Shop Talk 13: Carbide Threading Tools

[@kevinpulver4027]

Very helpful thank you! I'm just a hobbyest who's never done any single point threading and trying to tool up. I want to make some high crown head nuts for an antique hit and miss engine. 5/8- 11 threads. It was SO frustrating trying to find what insert to use. I only learned by Googling tonight that LT stands for laydown thread. Your video showed me why they call it that- (because the old style ones on their way out actually stood up!). At your recommendation I bought the little black book and FYI the Third Edition does add SAE/inch also! (I'm writing this 6 yrs after the vid came out) Great job teaching, and much appreciated!

[@barryantrim6508]

I started a job shop 10 years ago. I've used HSS for most everything. These videos explaining the nomenclature of the insert tooling has given me the confidence nudge I needed. Thanks for your generosity and efforts in sharing with the community.

[@Abom79]

Thats great Barry. i still use hss for many things, but mostly inserts for turning and threading.

[@raincoast2396]

You are the only one Adam, with a simple easy to understand style of getting across the information. Love the machining community on here, but almost all just skip over their tool holders and inserts when showing projects. As if we all have complete understanding! We don't. Your explanations now make the viewing that much more enjoyable. Cheers.

[@PorkBarrel.]

No one else on the web shows as much technical information. I really appreciate your time and talent for learning and have helped me tremendously even though I've been machining for 25 yrs. Hope you are grooming your son (if you don't have one get one) to carry on the family business. Thank you so much for all you do!!!

[@randallparker8477]

I like this series, you are a great "explainer", I kinda have known how the insert part #'s work ordering them for the operators in several shops, but I found your comments about grooving tools (and radius and parting) to be true. All the major mfg's available through the big distributors just use their catalog #'s for the tools, you have to use their books etc to find what you need by doing the cross referencing and sizing etc yourself. No standard that I ever found. Keep 'em coming!

[@Gary.7920]

Adam, These are very informative episodes. I really get a lot out of them, and it helps me when I am about to make an order for some inserts. Thanks for all you do. Gary 73-year-old Home Shop Machinist in North West Arkansas

[@Bobbycat115]

Hi Adam I bought myself a Vardex threading tool from KBC it is the best thing I have done for threading it is a lay down style and tougher then hell to brake a tool . I fined it dose not mater how tough or hard the material is. I get nice smooth finished threads . I use the 8 to 48 TPI insert . The first thread I cut was a 17/8 - 8 for a test plug for the spindle for that old 1929 13" Southbend I bought from Don Cossitt and cut it on that lathe and it finished perfect . The one thing I like is just put the tool to the side of the chuck to square it up and go to work. No fish tail needed . Love your videos dont stop.

[@SuperAWaC]

There's so many high quality online courses for STEM but very few to none for trades. Your format is easy to understand.

[@DJnach3157]

doing an outstanding job Adam. I have been watching your chanel for the last several years now and ery much enjoy watching you work. I am a carpenter by trade as well as a cabinet maker so I am always fabricating something from scratch. I am always ribbed about how I like to build things because when I do it , I do it the right way the first time and usually twice as strong and twice as many fasteners that are needed so that I never have to worry about it coming apart. my wife always says hope that you have to take it apart because it usually needs to be redone because taking it apart is not an option. it has been glued and screwed together so that it won't come apart. Anyways Adam, I think you are doing an outstanding job. I have also been watching Tom's channel and Keith' s channel and enjoying every minute of all of you guy's work. I have always had an interest in metal machining and maybe take it up here soon. I am 59 now but no where ready to retire. Darrell Nachtigal DJ Naughty Woods Edmonton, Alberta Canada

[@leebarnes655]

No need to worry about content Adam. As usual top drawer stuff as long you keep informing us of why you think what you think and the road to that conclusion is shown, I really can't ask for more.

[@petersharman3408]

Thank you Adam for taking more interest in the industry. Peter Australia

[@cavemansmancave9025]

Thanks for taking the time to do this, Adam. I struggle with the insert codes. Even when I go to manufacturer websites, I find that without already knowing the correct codes, it's a challenge to find what I want. This helps. Thanks, John

[@Abom79]

Glad it helped out John

[@sharkrivermachine]

I enjoy this video format. It is good hearing from you during the week.

[@Effay513]

Anything you post is interesting to me. I love your style. love your work.

[@Natestang302]

These videos are great! Been in machining for about 2 years now and starting to learn CNC as well! Definitely gotta get me one of those books! Thanks!

[@richardsteadman2246]

Very informative, I recently took delivery of the black book after seeing it on your video and now I will be adding threading tools to my collection. Cheers!

[@glennfelpel9785]

Very well done Adam, The video was excellent, the personal experience is what we want to hear. We can listen to a salesman any day but I come here for your experience. Thank you much.

[@bobandres5559]

Hi Adam, thanks for these vids, the company i work for bought out an old machinist shop and all his tools and tooling. I have tool cabinets of tools with a drawer full of carbide inserts which i knew very little about. I am a welder fabricator learning from doing jobs for work. I'm understanding this stuff more and more thanks to you. Ordered a t shirt .

[@billlee5307]

Another very useful video. Many thanks Adam! This kind of information is often something a person needs exactly when there is little time to research it on one's own.

[@horseshoe_nc]

I just seen this book at a local fastener shop today, Quality Fasteners. I am going to pick one up soon. I really enjoy your videos, keep it up.

[@RGSABloke]

Hey Adam, this co tent is great, the Black Book folks assured me that both the Imperial and Metric versions of the 'Black Book' have all the info on the inserts and they told me that they may be shipping out of the UK shortly to reduce costs. Thanks for sharing. Kindest regards. Joe.

[@RGSABloke]

Adam, I also scoped out oUt the 'Fasteners Black Book' which looks awesome also. Joe.

[@MarkGarth]

Both books are excellent, well worth the investment.

[@tridium-go6hw]

Hey Adam, I was re-watching a video you posted in 2013 on spiral flute taps. Wow, what a difference! The shop was a lot sparser (and the ceiling wasn't done either), video and sound quality, etc. You've come a long way! Of course the content was and is always relevant. Good job!

[@TomZelickman]

I like the variety, Adam. You won't please everyone all of the time and if mixing things up is what makes you happy then I'd say keep doing it! It's bound to help someone out there in the world... Best wishes, Tom Z

[@Abom79]

+Tom Zelickman (Inspiration Metalworks) But they say I can please some people some of the time. 😆

[@MrJugsstein]

Good one Adam you always make it seem like a mate dropped round and asked a question. yet still get the info across.

[@johnwalker4602]

This is the vid I have been waiting for and pretty well covered all the information I was in need of. Thank you and as always a fine job of presentation of the topic.

[@charlescompton4495]

Shop talks are great. I hope to see more, Greg.

[@jedirogar]

Thanks and really glad I found your vid!! It’s been over 20yrs since I’ve Cnc machined and I just picked up a lathe for some projects and this is exactly the info I was looking for!!! Great tips and I’ll be ordering the books, thanks!!!

[@shadowfox929]

Thanks for going through all that. Explaining how to dig out this information is very helpful.

[@gmckinney626]

Adam, always learning from shop talk. Keep the knowledge flowing!

[@Abom79]

+Greg Last Thanks Greg, I'll keep em coming...

[@oddgeirvarhaug7087]

Hey Adam, nice and informative. One thing to mention is if you find a insert you can determine if its made for internal or external by looking at the orientation of the triangle. The flat side and cutting part should always face in direction of threading. Hope this make sense.

[@Abom79]

Yessir, I can look and tell. Also applys for top notch inserts :)

[@vajake1]

Thanks so much for posting this. I really enjoyed it and I learned a lot. I have been given a lot of this type of tooling and I needed these lessons to try to understand what I have and how to use it. Thanks again!

[@Abom79]

Glad it could help you

[@johnfry9010]

I am new to all this and this helps unravel the mystery .

[@RyanWeishalla]

Nice presentation of the information. I've noticed that some places seem to use IR instead of NR for internal inserts.

[@MrCubflyer]

Thanks for the explanation Ive just started using my lathe and I've never done threading but after your explanation I think I can figure it out.

[@itsaposcj5]

Great video. I would love to see more on the tool holders themselves. What are the good ones for threading internal vs external for smaller tool holders like 3/8" or smaller.

[@erikdevaney4781]

love the shop talk. i as well get alot of questions about car and automotive concerns like type or style of tool. best way to use and maintaining the properly. thanx again ABOM maybe shop talk on some of your equipment. like how to properly change band saw blade

[@silveradoman298]

Another good shop talk adam. Id like to see a video on drills. Drill sizing, different types of drills, when to use different grades of drills (cobalt, hss, carbide etc.) spotting drills vs center drills, tips on how to not harden material when drilling and sharpening drills.

[@bcwrangler]

Thank you Professor Booth! I'm new to the insert stuff and having to do up a future backing plate for a Boxford lathe(using the Whitworth pitch) this helps immensely

[@rlsimpso]

This was a very helpful video. That book looks like a good one. One of my local suppliers has them on sale for $20. I need to pick up a copy. Thanks for posting. This Shoptalk series is great.

[@Abom79]

Good price and worth having around.

[@ajfreeze215]

What are your thoughts on the full profile versus partial? I have to make a draw tube adapter and thread both internal and external M42x1.5 threads. If I buy full profile, I have to buy 10 inserts (5 minimum of each) to do it, just for this one non-paying job. It's because I need an adapter plate for a new chuck on my subspindle. If I could just drill and tap 3 more holes in the spindle, it would make my life easier because I would need the adapter plate. Half the people I talk to think it's crazy to try, the other say go for it. It's a brand new lathe. Love the channel, and thank you for taking the time to post videos.

[@johndavid3343]

Thanks Adam, good vid. I like the Shop talk format, I'll watch whatever topic you post. :)

[@davidgiles5461]

Brilliant contents! Inserts and tool holders is a mine field to me so this info really helps. Thank you 👌

[@travisshrewsbury7169]

good stuff man,would really like to see you go over some of that pile of cutters you got for the K&T,specific purpose,feeds n speeds,ect.

[@bcbloc02]

Funny, I just spent the evening doing threading, broke my only acme 22ER I had, found out how much they cost so skipped it and ground my own thread tool because I really wanted a flatter thread anyway because it is really a locking drive mechanism for the hoist. During that time my brain left and I really struggled making an obvious mistake. I got it knocked out after 6hrs to cut 2 bastard mating threads. lol Guess I will be needing to order up some seats and inserts the next time they are on sale.

[@yqwgjsg]

bcbloc02 Hey Brian, hope you shot some video of that. When are you going to teach Bailey how to use that camera?

[@bcbloc02]

Hammer0f Thor Baily needs a camera that plugs in the wall for as slow as I work. lol

[@rklassen1054]

Video quality and content are awesome. No need to apologize about the camera. GoPro camera have a small aperture, which helps keep everything in focus. It has been my experience that focus control becomes an issue with larger aperture cameras. Keep on doing what you are doing .

[@mikemcewen2092]

The inserts we used were for a certain thread only,you would leave the od a little big and the insert tops the the thread down to correct dia and deburrs it.

[@paulchiarello5139]

Thanks Adam! This helps me in my quest to understand inserted tooling. I appreciated the turning and threading tools/inserts. I'd like to see something on inserted face/shell mill tooling. I just picked up a face mill that uses EP1408 inserts, and I'm getting overwhelmed by the information.

[@robertpartsmade5832]

Hi Adam, regards from the UK , great content as always , now have a copy of the "black book " in my shop ( can now ref your US metal standards against UK materials ) keep up the good work . Cheers Robert PARTSMADE

[@cosprint]

Your doing a great job of explaining, Keep up the good work. and Thanks.

[@josemanuelmartinruiz624]

Hi, I'm thinking about buying a SER1212H16 tool with 16-gauge ag60 but I do not know whether to buy vp15tf (pvd) or ue6020 (cvd) I know that vp 15tf can be made with stainless steel but I usually use steel f114, what do you recommend?

[@josemanuelmartinruiz624]

hello adam please answer my question

[@MrCubflyer]

Thanks I've never done single point threading and I need to do a 3/4-10 .I'm going to give it a shot.

[@gk6305]

I look foward to more and more of these videos. Keep it up.

[@richardvaughan6783]

Hi Adam. A great series of videos. You said the threading insert was Right Handed Can you use it for Left Hand threading. Many thanks again Richard. UK.

[@leonardwinn3446]

Hi Adam, Thanks for the clear explanations. How about a video about knurling ? Straight, checker, clamp vs thrust, also why does the diameter of the part not have to be a multiple of the pitch of the knurling tool ? Thanks again for your great channel. Len

[@StreuB1]

Great episode, Adam!! These threading inserts have always been a mystery to me. This made total sense. Both videos really broke things down for a lot of people I think. Face Mills is my suggestion for an episode!!! BTW I just bought the dominion "recycler" from discotech. Can't wait to get it! Great value in that face mill I think.

[@Abom79]

Brian Streufert That's great Brian! That's a nice tool and high quality. Don't forget you'll need an R8 mill adaptor as well.

[@StreuB1]

Yep, got a used R8 to 1" arbor for $42. No brand listed but it looks like an old USA made. Scored inserts as well so all in all, I'll have a complete face mill and inserts for $200. Not too shabby.

[@douglasthompson2740]

Great video Adam. Maybe the SECO literature would cover grooving and SAE threading? The rep that was on Dale's vid made reference to the manual or whatever saying it was available through tooling retailers but the threading and grooving were subjects among many that he didn't get into and he hasn't been back so you are doing a needed service. Also the practical info on which performs best in the real world is very useful. Thanks again. Keep expanding the topic and I will keep watching as I am just getting into inserts. Take care. Doug

[@sjb_rnd]

Great job Adam. Its amazing how much technical detail there to a machinists trade. I am looking forward to seeing the Indicator Master video I emailed you about regarding the different types on indicators and how to use them properly. keep up the great work on your videos!

[@Abom79]

Thanks Stephen. Yes I plan to do something on indicators, maybe a couple videos on the different types.

[@thegreatga]

Sweet! A mid week video!

[@ccfoam]

Thanks for the great information Adam. Any chance you keep the black book in the same drawer as the K&T Manual? Have a great day!

[@johnstrange6799]

Greatly appreciate your efforts. Thank you.

[@shawnmrfixitlee6478]

Very interesting Adam , Tons of info and easy to understand.. Thanks man !!

[@Abom79]

Thanks Shawn

[@afnDavid]

2 questions: About when was this standardized nomenclature system invented? And 2: Who invented it? was there a trade organization? Something like JEDEC, JETEC, RMA/RETMA, EIA/CEG for example were early trade groups who invented various electrical and electronics nomenclature systems. JEDEC- Joint Electronic Device Engineering Council. JETEC - Joint Electron Tube Engineering Council. RMA - Radio Manufacturing Association. EIA/CEG - Electronics Industry Association/ Consumer Electronics Group.

[@taznelson3146]

these videos are great and I'd like to know about parting tool inserts

[@westendshop8528]

Awesome information. Keep up the good work.

[@badijks]

hello adam i use the type 16 threading inserts also. i use it for cutting metric, metric fine, unf, unc, and gasthreads. i also use for every pitch or od a different underplate under the insert this is because my toolholder has standerd a angle of 1.5 degrees positive and the insert can cut the proper profile and doesnt wear on the sides of the insert also can i cut left pitched threads with the same tool holder and insert i only need to fit a negative underplate under the insert

[@EitriBrokkr]

What carbide shim do you use with them? I've had a heck of a time trying to get the shims to line up under the cutting tooth. Its a brand new tool holder, but maybe the pocket is wrong?

[@Sicktrickintuner]

Will you do parting tools along with grooving tools? Like how far you can reach out and cut without breaking it? Or the old lantern style holder

[@WildmanTech]

For your camera upgrade, you can get a refirb T5i direct from Canon for under $500 with a nice zoom lens. Keep up the good work.

[@tolydukhovny682]

adam, thank you for the very straightforward and clear classification of carb inserts. what would you say about the hss inserts? some folk swear by them. -toly

[@TheMan1510]

Very good info, Adam. Thanks!

[@arichardson46]

Excellent video Adam, keep em coming.👍👍

[@stanwooddave9758]

Thanks so much for taking the time to setup or the video, shooting the video, and SHARING. :-) Very informative.

[@Abom79]

+Stanwood Dave You bet Dave!

[@emildekoven4872]

Very informative and your pedagogical method (whatever that is....?) is SUPERB.....! Something about tapers would be also informative.....

[@WilliamTMusil]

I have a question re: the grooving tool, sort of. Sorry if this sounds dumb. I have seen you use the grooving tool for radial cuts on the lathe. I recall Brian at bcblock02 cut slugs out of a diesel engine deck plate he manufactured with a hole saw on a mill. Now I know you could easily farm such a job out to a plasma cam, do it in-house with plasma or a torch and a magnetic circle cutting fixture, or just just hog out and bore all the material, but say you had large holes in a flat that you wanted to cut, but didn't want to waste all the material in chips but still wanted to cut those holes on a mill. Is there a setup with the grooving tool, like an offset boring bar with the grooving tool held parallel with the spindle of the mill that could be used to rough slugs out of plate? Like a spinning spindle mounted tool holder?

[@WilliamTMusil]

Or something like a horizontal boring mill spindle for a mill or a jig bore? We know Brian has a nice HBM that he plans on setting up, and you have a nice one at Motion you have shown in your vids. Basically, could somebody without access to an HBM do such a job on a mill, without a hole saw?

[@robgerrits4097]

Clear explanations on carbide tips! Thanks for sharing:):)

[@williamsquires3070]

Well, now that you've covered threading tools/inserts, maybe you can cover threads next?

[@elgardog]

Hi, That was a great explanation, many thanks, Dave, UK

[@chrischtea]

when insert threating, is a righthand insert for "going in" and a lefthand insert for cutting on the way out?

[@garyc5483]

Hi Adam thanks for sharing. By laydown insert tool I presume you are referring to "negative rake" tools. Maybe that is something that can be covered in a later episode. ie Pro's & cons of positive versus negative rake tools etc. regards from the UK

[@Abom79]

They are negative rake but the cutting edge has positive rake angles molded in.

[@onehot57]

Thanks for the great info Adam!

[@thandles_workshop]

Very good info Adam! you make it easy to understand.. My lathe is old and have no brake in it.. do i need more revs with garbide inserts vs hss?

[@Abom79]

+Tapsa Surface speed for carbide is much higher then high speed steel. In many cases to slow of a speed will cause the inserts or tool to chip or break.

[@thandles_workshop]

Abom79 Ok. Thats good to know. What speed do you recommend for threading mostly 1/2 to 1inch threads?

[@Abom79]

I'm usually in the 300-400 rpm range

[@thandles_workshop]

Ok. I can do that without crash.. 😂😂

[@theromihs]

Thanks Adam, that was really helpful.

[@billdlv]

Nice job Adam.

[@edgarmilson8686]

Hello Adam, I would like to see you do a shop tour of your shop. In the background you have a huge wheel and I would love to know what that is all about. Regards, Edgar

[@Abom79]

I've done a couple and I believe I did one in one fo the first shop talk episodes, but I'll keep your request on my list. Thanks.

[@michaelfiller3452]

Another great video. I love the shop talk series. I'm a new-bie at this, and this helped explain alot. Does "lay-down" mean you lay the insert on a shelf, screw or clamp it in place, while a "stand-up" is sort of hanging on the outer side of the holder? I had seen some threading inserts that you would rotate to bring up a fresh cutting surface, mounted to the side. Is that "stand-up"? Are there other types in this regard? I am guessing the screw-down are those with a hole through the middle? I've seen others that use a little arm, held down with a fastener completely outside the insert. A very tiny version of the milling machine clamps that set on a step block, "toe clamps"? Anyway, too long a post, but a great video, I really appreciate what you do, and know it takes a lot of time and effort. You must write out a script or story-board to keep it all straight, lol!

[@Abom79]

We speak of lay down and stand up by the way the insert is mounted on the tool. The lay down style looks like it's laying down on it back flat, in a horizontal plane. The stand up type look to be mounted in a vertical position.

[@steveantal5834]

once again bud. very informative. thanks a bunch, and great video. from my perspective it's whay we look for.

[@WAF74]

Hey Adam, I can't tell from the diagram, but what's the difference between an ER and an NL (EL / NR too) insert? The diagram for each looks identical or at least geometrically similar. Can you cheat and use a single type of insert in the opposite type of holder? Fewer parts to keep track of in the shop...

[@Abom79]

+w.A.f. Actually you can cheat there. A NR insert will work on on an EL holder and vise versa. So basically the threading insert I shown for my boring bar can also be used for a left handed external holder.

[@TheRetiredtech]

I like these info pieces. thanks for uploading them

[@kostasg666]

This is very interesting staff.I am waiting for gearbox shaft part 3.

[@mertsilliker1682]

very ingeresting, I am looking for the least amount of inserts to keep down cost. doing home work and pleasure. any suggestions, 13 by 40 lathe.

[@troyam6607]

Aussie one Adam just says (threading) not metric. go figure. Any chance you could elaborate on the ISO Metric Cutting insert Versus the 60° insert? both cut 60° thread but which to use? Cheers Troy

[@overkillaudioinc]

Great vid's Adam as always! Just FYI, On a Big screen....27" or larger, I can read the book and everything just fine!

[@Abom79]

I bet the new tv's look great! I have an older model 55" Vizio. It looks good but i think new ones are sharper.

[@tomherd4179]

Would like to see how to find an Insert if one knows the tool holder code (MSDNN-16-5). I did buy the Engineers Black Book and tried to figure out the insert from that. I managed to (I think) figure out it was square, 0 degree, and circle of 0.625. But that leaves a number of missing values. SN??5?? I am a home hobbyist retired so uses would be just general stuff. Beginning to think the missing values would be determined by the job requirements.

[@mysteriousstranger239]

Thanks for the info Adam very useful information

[@wgm-en2gx]

Adam, that was a great presentation. I learned a lot (I'm not a machinist). Although I wished you covered "laid down" vs "stand up". Also, are the inserts made of all the same material or in other words is carbide always carbide or are their different compounds of carbide and other materials...

[@timholsten]

Could you do a video on the cost of getting started? I like to watch and would like to get into this but the cost is unreal. I was offered a Southbend 9 $800. That is with no tooling. Alot of us out here would like to see what your investment is. love your channel, keep going.

[@howder1951]

As always, great video Adam, you are clearing the air about inserts, a little bit adds up in the long run, that is called progressive knowledge. My request; Could you do parting tools sometime, a couple other tubers have been commenting on this, so it is somewhat timely. Thanks. PS; almost 6000 views at this time, and it looks like they all commented!WTG Abom79

[@justinserra4844]

New viewer, love the vids. What would be a good first lathe and mill for beginners for home gerauge? Thanks again for the great vids

[@ML-tu3eh]

hi sir what insert do i need? im threading 6tpi 304 stainless!

[@badrita1059]

your videos are great! you should totally have a catchy slogan or something you say in closing.
