What's the BEST Endmill for Beginners?

[@Machining-tutorials]

Quick clarification: In this video, I mentioned that HSS (High-Speed Steel) is out of the equation, which isn’t entirely accurate. HSS is still widely used, especially in drills and other tools, and performs well in many applications. However, carbide is a "newer" technology designed to handle higher speeds and tougher materials, like steel, more efficiently. If I had to choose between the two for cutting steel, carbide would be my pick for its speed and durability. That said, now that I’m a bit older and wiser (haha), I plan to make an updated video in the future to share what I’ve learned and provide even better insights. Stay tuned, and thanks for your understanding!

[@Raul28153]

Before matriculating university, I spent over 20 years in tool rooms mold rooms and tool and die Never saw a carbide end mill. HSS is perfectly fine for all alloys of steel just not pre-hardened. If there is a down side to it, it is that you have to go slower and pay more attention to coolant. In fact on mills such as the one you have there Carbide is probably the wrong choice almost all the time because your bearings are old and small and worn and not rigid enough to provide the ridigity carbide needs. So you are probably getting half the expected life of a carbide end mill.

[@professorjim6874]

And it's a universal mill with literally 7 different linear and rotary manual axes, so just doesn't have the... "rigibility" to use only carbide.

[@oh8wingman]

I agree with you wholeheartedly. HSS has been around forever and precedes carbide by probably 50 years. Carbide is great on tool steel or stainless steel parts but for mild low carbon steel HSS is more than adequate especially if you use a good coolant system since heat is what kills any mill tool.

[@DavidHerscher]

Facts.

[@Dane33781]

If your machine isn't clapped out, carbide can be more economical than hss in the long run. You also have the option of not using coolant at all with carbide. I actually climb with carbide on my Bridgeport for finish cuts. It can be done.

[@fpou1557]

if you have coolant on directly on a HSS endmill and lower the speed a little bit and take smaller cuts you can cut cut steel no problem (not hardened steel tho) and carbide is always better but cost more

[@crucettij]

I climb cut the final .010 or so. Chip load is small, finish is better. But never for roughing!

[@markmarkiewicz9848]

Also to add, when slot cutting, use a 2, 3, or 5 flute. Never a 4 flute, unless you can accept it to cut oversized. But then the deeper the slot, other issues can come up. But to use an under size cutter, ruff and finish to size if is critical.

[@michaellunebach9714]

I’ve been using high-speed steel and mills on Steel for 40 years. You just need to get your speed and depth of cut correct. A little cutting oil won’t hurt. Of the three carbide end Mills, I think you chose the wrong one. I would’ve gone with the larger one. The larger end mill would have been more rigid and all-around more useful if you were only going to buy one.

There is a time and place for climb milling, it definitely serves a purpose, and HSS can be used to cut steel, it just doesn’t stay as sharp as long...

[@Sketch1994]

I actually climb cut on anything, from the clapped out minimill at work and a equally clapped out 40 taper knee mill, to the brand spanking new 50 taper big boy box way horizontal universal manual mill (with a universal huron head attachment, a +-45° table, a universal angle rotary/dividing/differential indexing/helical milling head-tailstock attachment along the dreams of finding the elusive vertical slotting head attachment...universal af in general) and the VMC of course. On manual machines I can do some pretty fine work on steel with quality HSS-E tools, but when it comes to VMC work (even if it's just a one off prototype/jig/fixture/mold/die/stamp) I cringe whenever I as much as touch an HSS tool that isn't a tap or a countersink (not a chamfering tool though) on the bench

[@bobmac9070]

I’d like to correct you. Not all but many older machines “if” the gibs and ways are in good condition and you have a good table and you have sufficient HP, you can climb mill which I personally did myself for over 30 years as an application specialist for a major carbide end mill company. (Which is better and preferred ) on most all carbide end mills. Conventional cutting will prematurely wear your end mill out because of the rubbing from a zero chip thickness to a very heavy chip throwing all the heat on the tool and dulling the tool quickly. Climb milling puts all the heat into the chip so less heat is at the edge of the tool and less wear and tear on your tools. The part will be barely warm to the touch. The proper SFPM-surface feet per minute and CPT-chip load per tooth is required for a given material. This will help the performance of the tool in a given material.

[@rholanddelamerced]

What is the difference of HSE and HSS end mills? I bought 2 HSE 2-flute end mills and it can not flatten a pre-drilled hole and its sharp points will wear out as soon as it touches the work piece; also its cheaper for only $18.40. Then we bought HSS Co. no 8; its points do not dull fast unless you made a mistake while setting it. I just wanna know the difference of the 2. Thank you!

[@CactusforceX]

interesting, I have been told by some people to "always climb mill" even on a manual machine, but my old mentor said conventional milling is the way you do it. I always have better results like that anyway!

[@sevakmoradian6716]

If the machine is ball screw clim cutting is the way to go and all cnc machines are ball screw. Some manual machines are just screw and nuts and it has lots of backlash, so it’s better to use conventional.

[@peterfoldesi483]

Depends on the machine, with old machines which has a lot of slop in each axis, conventional, because it won't pull the part on the end mill If the machine isn't a half dead one, and can do movements without slop, then climb Climb cut has an advantage because the edges on the tool won't rub on the piece, increasing tool life, and if I'm right it needs less power from the spindle as well, but it needs a rigid machine, otherwise the tool will destroy itself

[@partmaker]

I just retired from 40 years in the shop. Imho there are not any firm rules as there are a bunch of variables to consider. As one poster mentioned yes, climb cutting can be difficult and even disastrous on a machine with a large amount of backlash. Climb cut will often give the better surface finish. One thing I have done on a loose machine is to remove bulk material cutting conventional and if a climb cut is desired tighten the table lock slightly on the axis you are cutting on to help the cutter not grab the work. Its worth it to take some time and adjust as much backlash as you can out of your machine. In machining experience is golden so get in there and do it. Be prepared to pop a few cutters but that is how it goes.

[@Zkkr429]

Conventional mill on a manual if you’re taking any type of meaningful cut. Climb cut at your peril!

[@hansong_official]

Which Brand End mill do you use?

[@AshokSaini-sf3ev]

Nice presentation

[@Dominator2930]

I have to disagree on the point of choosing the .5 over the .75 because of price. If you can't afford it don't buy one, but if you can afford a .75 carbide FEM and it makes sense in your application, use it. With proper use it will last a long time and you will be able to hog through much more material than the .5 FEM. While it is much more expensive, if you're using proper feed rates then it should be able to make you much more money than you spent in the time saved cutting your material while lasting a long time.

[@partmaker]

The smaller cutter you can spin a bit faster and keeping chip load the same if you can will give a little more feed ability

[@craigtate5930]

What brand and model is the endmill you are using in this vid?

[@jakeperry8773]

That hss roughing endmill would've taken all your extra material in one pass. You just have to keep the cutter cool with some kind of cutting fluid. Those teeth on roughing endmills (aka turbo mills) greatly reduce the amount of power needed to take the same cut with a regular endmill. Also it's Rigidity not rigibility. We also use conventional milling on manual machines because of feed screw backlash not lack of rigidity. If anything, most of the manual machines I have used are MORE rigid than a lot of CNCs

[@sjaakwanninkhof4872]

Thank you very much

[@cosmiccolonel]

HSS is no good for steel!! Bullshit mate!! Every standard drill bit is made from HSS so how are they able to drill through it?..

[@Migman2020]

how do you actually do a perfect feed rate on a manual mill once you have worked out the feed rate for your tool? got my RPM set for my two tooth carbide end mill with 260mm per min travel.. but how do i actually put that into practice? new to machining here )

[@CJ-ty8sv]

Really need more info but in short, if hand cranking, then it really comes down to feel with experience. If you have / are using a power feed, then you can get really close with a stopwatch / timer and adjust the power feed speed till you get what you want, then make your cut(s)... Just take your desired feed, then divide it by 6 and mark off the distance that you get (rounding to nearest .5 (or even whole number) if you get a decimal will get you close enough 99% of the time) and then adjust the power feed until your mill travers's that distance in 10 seconds. Unless your using less than 3mm (1/8") endmills, I wouldn't worry about the feed error from rounding, or just always round down so to reduce chip load rather than rounding up and increasing chip load. For example, lets say that you needed a feed of 300mm/min, just divide that by 6 thus getting 50, so mark of a 50mm distance and adjust the feed until you cover that 50mm distance in exactly (or as close to) 10 seconds time. If you have a DRO, then its even easier since you can start the feed and the stopwatch at the same time and kick the feed off when you hit 10sec, and see how much the DRO said you moved, then adjust the speed unitl the DRO is as close to the target number as you can get (i.e., 50mm in this example). *EDIT:* Rereading an older post because of a "Like" popping up and I realized I had an error in my time vs. distance math.. Was thinking of the 10 second interval and accidentally said to divide by 10 which it really should be 6 to arrive at the distance per 10 seconds.

[@markmarkiewicz9848]

Climb cuttings on a lead screw machine can problematic. A CNC mill has a ball screw, so it will not walk the cutter across the cut like a typical manual mill like a Bridgeport with a standard lead screw. Many reasons why to climb cut, and only a few reasons to conventional cut . Climb cut 99% to 100% of the time if possible on a CNC. Conventional cutting on a BP, because you really have no choice.(Lead screw, no ball screw) Just one example: Conventional cutting pulls the cutter into the work, (cutting more than you want) and pulls the parts out of a vice. Climb cutting pushes the cutter away, and the part down into the vice. Climb cut leaves a better finish and longer tool life Hard materials sometimes need to be conventional cut. And so on,,,,,,
