The Diamond Tool Holder

This video is not a test for the Diamond Tool Holder; it's rather a test for my mini lathe comparing its performance over the conventional HSS Cobalt toolbits I use.
We also take a closer look on another tool from Eccentric Engineering. The FoR Inverted Parting Tool Holder.
I have used this tool for over a year now and I’m more than satisfied!
For more information about the Diamond Tool Holder and the FoR Inverted Parting Tool visit Eccentric Engineering web site at: www.eccentricengineering.com.au/
If you like to see more videos of the Diamond Tool Holder in action on bigger and more powerful lathes than mine. Check these links!

Thank you for an excellent overview of the tangential ‘diamond ‘ tool holder. I look forward to trying out my own when they arrive.

[@JimmysCanal]

Thanks a lot for the comment, I appreciate it! Its an easy to use tool and can easily re-sharpened. I'm sure that you'll enjoy using it. Thanks again sir! All the best Dimitris

Thank you for demonstrating how to grind the cutter for cutting threads.

[@JimmysCanal]

Thanks for the comment. Happy new Year! Jimmy

[@rogercrier]

I've got one of these and the finishes I am getting are the best I've ever got They also take nice big cuts. Easy to sharpen correctly, and much sharper than the cheap carbide most hobbyists can afford Notice he uses the opposite hand tool for threading as it clears the chuck better. I would buy another if mine got stolen. There is a UK Distrbutor now

[@kenheppener6632]

Hi Jimmy....Excellent video as usual....I have one of those Diamond Tool Holders that I got about four years ago....I think they are really good and I use it for nearly all my turning....Keep up the good work.

[@JimmysCanal]

Hello Ken, Glad to hear you again, my friend! Yes I agree, there are really good tools and I'm sure that pretty soon I’ll find how to use them more effectively! Thanks again for your comment. Cheers Jimmy

[@ShevillMathers]

Their round HSS & Crobalt tool steel leaves a superb finish.

[@JimmysCanal]

[@pjhalchemy]

Really excellent editing and video Dimitris. Love that you breezed through the boring stuff and let us see the meat with good music! I can see why you like them, especially with the finish and Big depth of cuts you were making on your mini with little singing except for the brass which is normal. I also like the simple sharpening and that you could grind a threading tool so easily. Thanks for sharing your tests with us...may have to save some shekels for some of them. ~¿@ ~PJ

[@JimmysCanal]

Thank you PJ. I must tell you that except of what you see in the video, I test my mini lathe while using the Diamond Tool Holder on 1045 steel and Calmax® tool steel. Also on 6082 aluminum, copper and plastic. I had excellent results on all those materials. The only exception was copper that I couldn't manage to have a good finish on deeper cuts. Yes, I agree with you for the 'singing', this I think was unavoidable since I didn't use cutting oil as also it was close the limit of the lathe motor to have the power for the cut. As for sharpening it's very easy and safe, on grinding the threading tool we must be careful because the hands are closer to the wheel! It's worth to save some money to buy a set!!! Glad to share! Thanks again. Dimitris

Hi Jimmy with your experience from today would you still buy the diamond holder or build it DIY.. How often do you use it? Greetings from Austria

[@JimmysCanal]

Hey Wolfgang, I use it all the time and I'm very satisfied with it!! With the tools that I have in my disposal it is impossible to make one, but if I had the machines and tooling that you have I'll tried it for sure. Here is something that is worth seen it simply to get ideas: www.toolsandmods.com/docs/ralph_patterson_diamond_tool_holder.pdf Cheers Jimmy

[@vasilioskalimerkos4636]

realy Good!!!!!!

[@moholo8898]

You should not cut off in reverse with a threaded spindle. If the chuck comes loose you risk the tool, the part, the chuck and damage to the machine. Also, use a tray, pipe or a rod on hollow parts to catch the part and avoid damage to the part and ways. A tray will also keep some mess off the machine. Less mess and non disappearing parts is always a good thing.

[@JimmysCanal]

+Experiencing Technical Difficulties Hi, Thanks for the comment! There isn't any risk because my chuck has 3 bolts for clamping it to the spindle, so it's safe. As for the tray your are right, it is useful. Thanks again. Cheers Jimmy

[@robmckennie4203]

Are we sure a radius on the tool edge makes the tool last longer? I've always heard it's a tradeoff between finish and tool life.

[@JimmysCanal]

Please accept my apologies for the late reply. Thanks for asking! The manufacturer mention; about edge life and surface finish on his site. Here is the link: eccentricengineering.com.au/index.php?option=com_content&view=article&id=7&Itemid=32 I have seen that the radius helps the edge to last longer, but it’s important to say that I don’t make continuous and heavy use. To achieve fine surface finish use a fine diamond file to make the radius and try to keep it as small as you can. All the best Jimmy

[@M1KEMEX]

Do you notice much difference between regular HSS, M42 and Crobalt? If so, when and how?

[@JimmysCanal]

+M1KEMEX Hi, Thanks for asking! There is difference between HSS and M42 when cutting harder steels, like Impax supreme and 1.6582. M42 has 8% cobalt so, cuts easier and gives better finish. Crobalt it's even more better on stainless as well as on Impax and 1.6582 these two are similar to the 4140 steel. The max. cutting depth with HSS is 0.5mm; when M42 or Crobalt is used the depth goes up to 1mm. Cutting fluid must be used on all the previously mentioned steels and stainless. When turning free cutting steel M42 gives an almost mirror finish in up to 1mm depth of cut without using cutting fluid. In the description of the video there are a few links on how the Diamond tool holder performs on bigger and more powerful lathes. Thanks again All the best Jimmy

[@TheRamsalt]

What sizes did you buy for the parting blade holder and the diamond tool holder ? Thank you for the information.

[@JimmysCanal]

Hi, Thanks for asking. I bought the FoR 9.5 parting holder, as for the diamond tool holder I bought the smallest of the series, the one that has 8mm tool height. All the best Jimmy

[@TheRamsalt]

@@JimmysCanal Thank you for the info. I ordered one size up on the parting blade holder, seems like it would fit ok (i have the same lathe as you).

Don't mention it; it's a very nice tool you will enjoy for sure. All the best Jimmy

[@marcio.roberto.torneiro4897]

Hello, what the price of the tools? What site where you bought?

[@JimmysCanal]

Hello Marcio, Here is the official site of the Diamond Tool Holder: www.eccentricengineering.com.au/ As for prices and shipping charges, you must compare from the official site, with the US distributor and the UK distributor.

All the best Jimmy

[@stavrious]

hello dimitris,just found your chanel and really like it. would you say diamond set is still worth getting?

[@JimmysCanal]

Hello, Thank you for the comment, I really appreciate it! If you have a mini lathe I think that's worth to have at least a RH holder; mini lathes are lacking torque and carbide tools need torque to give fine finishes. HSS cutting tools work very well on mini lathes, I'm using it for years now without having any problem. One other advantage is the easy grinding, just touching it on the bench grinder and your are ready to work. All the best Dimitris

[@stavrious]

@@JimmysCanal just ordered optimum tu 1503,should arrive in 10 days.i don t know what cutting tools to get and i came across your vid

[@JimmysCanal]

The tu 1503 is a small machine, so be careful on the size of tools you going to choose; before buying the diamond tool holder, I suggest you to see if the smallest size can fit on your lathe holder: www.eccentricengineering.com.au/shop/The-Diamond-Tool-Holder-c46073009 It is quite expensive and it will be sad to buy it and find out that it can't fit on your lathe holder, wait to recieve your lathe first! Now, if the diamond tool can't be used, the best you can use are square HSS bits (6x6 or 8x8mm); you can try to use indexable carbides of course, but I don't know how this will perform. If you decide to go for carbide tools, I recommend you to buy an inexpensive one to start with. Cheers Dimitris

[@thebaron44]

I also have a Diamond tool holder purchased some...???????? 15 plus years ago, one looses tract of time. So much easier than grinding back rake, top rake, side rake, clearance etc. with the old Armstrong tool holders meant for the lamp post tool holders. Quick change...we waited for too long.

[@JimmysCanal]

thebaron44 I think that the Diamond tool holder is the perfect tool for all novice machinists like myself. The fast and easy grinding of the bit saves all of time. Wish to had a few more holders!! Thanks again for your comments! All the best Jimmy

[@thebaron44]

***** Yes at least one more set. One for positive rake and the other for zero rake, would save time. I have a 1/4'' set for my 11'' lathe and a 1/8'' set for my 5'' lathe.

[@JimmysCanal]

thebaron44 I will start saving money to buy one more set, this is for sure!

[@BRO-RU]

After grinding, allow the tool bit to air cool. Do not quench in water as this can cause cracking on the cutting edge. /eccentricengineering recomendation ....

[@JimmysCanal]

+Sergey Sorokin Thanks a lot for the tip, Sergey! I knew that this was applies for the Crobalt bits. That's explains to me why, while using the HSS bits the cutting edge was crack off! I'll assume that you have also a Diamond Tool Holder! I highly recommend you to use carbide tip on the holder.I bought a 1/4"x1/4" solid carbide to test it. The results...amazing finish in almost any material (copper is a little difficult, needs plenty cutting fluid) Thanks again All the best Jimmy

[@BRO-RU]

+JimmysCanal Jimmy, yes it was applies for Crobalt bits, but HSS is name of group varios composition, for some, it is appropriate, for the other is not, but it's better to keep in mind. Yes, I use them, they are my faivorite tools.Thanks for yuor advice, can you ask where you buy then? Sergey

[@JimmysCanal]

+Sergey Sorokin Hi Sergey, It's my favorite tool also, I use it all the time! I bought the carbide from this shop: www.internationaltools.gr/index1.html Thanks again All the best Jimmy

+JimmysCanal Thank for link, but a can't find they. Do you have name of manufacturer and part name? Do not want to buy a not original or bad. Sergey.

[@wolfitirol8347]

Hi again you use a tray in front of the support now.. You have hardened ways so is there another reason than the mess (use one too, made if leather, just asked me if there's more about it) Thanx

[@JimmysCanal]

Hi, Yes, the ways are hardened; but as you have already see my lathe is very small, so the mess from the chips must be removed with ease keeping the ways as clean as possible! Cheers Jimmy

[@wolfitirol8347]

@@JimmysCanal do the same with a piece of stiff leather in the size of your tray and underneath in the chip tray under the chuck i have a big 50 x 50 x 4 cm tablet into everything from above falls and which i can take with one hand and throw it into the metal waste regularly... it saves time and its cleaned up faster..

[@holmes230536]

Jimmy, I don't have the diamond holder but I'm sure you are happy with your choice, I read all of the comments on the first page and to me its six of one half dozen of the other, if your happy that's all that matters, the main reason for this comment is please do something with the gap between grinding wheel and table, there is a bad accident just waiting to happen, keep that table as close to the front of the wheel as you can or you are going to have a very bad nasty some time in the future, you could lose some fingers, it happens so fast you would never get your hands away in time, plus you are probably on your own in the shop, Edmund.........Alberta

Hi Walter, Thank you for your time and comment. Yes, I can say that I'm a happy user. The tool is great, I highly recommend it! As for the gap, you are absolutely right!! It's big enough to grab the bit as well as my fingers. You did well pointing this, not only for me but for all novice machinist. I need to be more careful in the future, that's for sure. I appreciate your concern. Thanks again! All the best Jimmy

[@paulk3573]

Hello sir, Following your advice, I watched the video "The Diamond Tool Holder". As always, very rewarding and pleasant to follow and that makes you want to buy. * In 2.06, you have 1 bar A.R.S. Would you have a link please? * En2.49, we see your grinding station. I have to equip myself to be able to sharpen my tools. Your white wheel has a grain of 80, but what is its diameter and thickness? Could you specify the power of the s.v.p. On the front of the drum there is the support shelf for the tools. Have you made a video for its realization? If you would not have information of the type: dimensions and especially its fixation in front of the reel? In 4.17, 4.23, 5.18, you control your practical sharpening angle: Epsilon = 60 ° to the template. I validate your method of control, questioned by some stakeholders. Indeed, it is only when the cutting angle "Gamma (o)" = 0, that the angle of manufacture Epsilon (r) = 60 ° In your case, the cutting angle Gamma (o) = 15 ° (given Eccentricenginer); hence the manufacturing angle Epsilon (r) is no longer equal to 60 °. Solution: tangent Epsilon (r) / 2 = Tangent 30 ° / Cosine 15 ° Let: 0.577 / 0.966 = 0.597 -> Epsilon (r) / 2 = 30 ° .85 and Epsilon (r) manufacturing is: 30 ° 85 × 2 = 61 ° 70. To control this calculated manufacturing angle, you must place your template in the plane (Pr); therefore the tool in place on the machine and the template, horizontal, pressed against a cylinder in the chuck and the angle of "60" against the tool. So inevitably there will be a game equal to the difference of the 2 values. Anyway you are absolutely right during your check. Excuse, it's a long time! In 20.33, you sharpen a cutting blade, what is its thickness? Will I have the pleasure of reading an answer? Thank you in advance and good day. P. k. (French)

Salut Paul, Heureux de savoir que vous trouvez ma vidéo utile. La barre HSS que vous avez vue à 2:06 je l’ai achetée dans un magasin d’usinage local, mais elle n’a pas de site Web; la taille de l'embout est de 6x6x100mm avec 12,5% de cobalt, je suis sûr que vous pouvez le trouver sur votre marché local. Pour le reste de l’affûtage, je vous enverrai un courrier électronique avec les détails si vous voulez le fabriquer vous-même. L’épaisseur de la lame que vous avez vue à 20:33 est de 1,6 mm, mais le support peut accepter des lames de cinq épaisseurs différentes, de 1 mm à 3,2 mm. Merci encore d'avoir demandé!

you measured the 60deg wrong on the threading tool, it has to be orthogonal to the axis of rotation, parallel with the horizon

What RPM were you using for parting?

[@JimmysCanal]

thebaron44 Hi, For free cutting steel close to 450rpm, for hard steels and brass around 320rpm. The max. diameter of the materials you see in this video was 20mm. Cheers Jimmy

[@thebaron44]

For me all parting on the back gears.. very slow...I heard your metal talking to you when parting...it was saying slow down.

[@JimmysCanal]

thebaron44 Thanks for the comment! Yes you are right! On hard steels like the Impax, 1.6582 and stainless I sould had to slow down! On brass and free cutting steel, I have seen that I can use 300-350 rpm on diameters up to 40mm. Cheers Jimmy

[@thebaron44]

***** We all must 'feel'' our way , for me parting was more difficult that thread cutting. I had better luck turning with a parting tool than parting with it. It's easier now but have been tinkering for 45 years.

Quite honestly, I don't get the benefit of this tool. I'm hearing chatter and squealing sounds and the finish is not satisfactory. The only advantage I can see is the cost of the tool bit, but the price of the tool holder is expensive. Other than that, there's nothing to write home about.

Fucking ridiculous 200 bucks for these tools. Not worth the money you can get just as good of a finish with just HSS bits if properly ground and they don't cost 200 bucks. Absolutely crazy price. It is mind boggling to me why anyone would spend good money on this.

[@JimmysCanal]

+Tony Emory Opinions are respected as long as they are decently expressed. If offend people makes you feel better, maybe it is something you should look it!

[@tonyemory3618]

+JimmysCanal How is my statement offensive to any person. It is simply the truth as far as i see it. People are free to make whatever choice they like i was simply stating. WHY would anyone want to spend that much money on a tool when a simple HSS tool bit would achieve the same results. But hay if you have the money to just throw away on superfluous tools go ahead. To be completely honest i went to their website and was shocked at the price. Expecting to see something in the neighborhood of 60 to 70 bucks. These are tools for a mini lathe after all and they should be priced accordingly i think. Just pisses me off that companies gouge people on so many things. I understand they are in business to make money so is everyone however there is no sense in gouging people that is just pure greed. offense was not my intent but if my language or choice of words offends you i think your the one that needs to take a closer look at one self. I personally could care less what people think or say about me it does not effect me nor will it ever bother me. I am a free thinking person and will always be that way.

[@ajofscott]

+Tony Emory I have a micro lathe, the tooling that best fits the toolrest are 50-70 dollars a set, although the carbide cutter is indexed, you cannot buy replacement cutters and must buy the whole setup again. I would pay the 200.00 once and have a holder that I can use readily available tool steel stock with over and over and over.

[@tonyemory3618]

Aaron Scott There must be replacement inserts available for the cutters you mention. They were made for the cutters you purchased originally so somewhere there is a place to buy them. Search E-bay and Amazon i would venture a guess you could buy the replacements you require. But if you would rather spend your money instead of time that is your choice. From the way I look at most things even though it may take me longer to make the tool than to buy it i have more time than i do money to waste on something that i could build. Personally i would rather spend my money on good stock and building materials than on tooling but there are some circumstances where a properly made tool is best and this may be one of those cases. In all honesty when i wrote that comment i was shocked at the price when i looked them up. I figured a set of these tools might cost 60 or 70 bucks but to find out they want almost 200 plus shipping i could not believe my eyes. I know machinist tools and the machines surrounding those tools are expensive and everyone knows when you buy a lathe expect to spend more on tooling for that machine than the machine itself. I have a Mini Lathe from Harbor Freight. Mine must have been one of the good ones as the run-out on the spindle and chuck is less than 1 thou. I thought that was pretty good for a cheap machine. Anyway i have recently acquired a much larger REAL lathe a south bend 10'' and even though i mostly use the larger lathe for everyday projects the mini lathe still has its place in my shop. My first thought was to sell the mini lathe thinking i would not use it but i find myself using it to make small pins and things that would be somewhat difficult to make on the larger one so i decided to keep it my favorite thing about the small lathe is its variable speed ability without the need to change belts i wish i had this on my larger lathe.

[@ajofscott]

You could obtain a VFD to run the AC motor on the large lathe giving you speed variability.
