An important detail on double slit collets like the ER-32 is that it needs a minimum engagement length of 2/3rds to clamp well. A single slit collet can hold pieces with very short engagement. Clamping short things in ER-style collets can damage them!
@kitsgarage5931
@kitsgarage5931 4 месяца назад
While technically true, we got away with a lot with a cheap set of ER32's at my last place of work. We clammed things only 1-5mm long in them with quite regularity (though they were also only 3-6mm in diameter) without any issues. Bit fiddly though.
@hoxviii
@hoxviii 4 месяца назад
Came to say exactly this, when I was looking into collet sets I saw that ER style sets only guarantee concentricity if your part engages ~2/3 depth or more- a remnant from originally being designed as a tool holder that was later adapted to workholding. 5C style collets will grip and be concentric so long as your part reaches past the gripping face. Really only matter if you're doing a lot with really short parts, but is why I started with a 5C set and added an ER set later.
@Self_Evident
@Self_Evident 4 месяца назад
That 2/3rds requirement is not true if you have a seperate piece of stock in the back end of the collet the same diameter as, or ever-so-slightly smaller in diameter than, the actual work piece. Just like when holding a small piece in one end of a vice jaw, it's good to have a similar size piece in the other end for a better hold.

Quinn, Thank you, Thank you, Thank you! For all of your excellent videos. I'm 72 and a life long woodworker. But my community's woodworking shop inherited a LOVELY vintage metal working lathe (Taiwanese built JET-1024 (??) circa 1980s or so, heavy as all heck). No electronic controls, no DRO, but very nicely maintained and buttery smooth in operation. And I hadn't a clue how it works. But, I want to make some things with it. I've now been watching your videos for the past 6 weeks trying to absorb some of the basics of turning on a metal lathe. In the process, I've learned a ton about metrology, and found This Old Tony's, Abom's and Mr. Pete's channels. I wish I could have learned from the 90-year old master machinist who donated the lathe before he passed (it was his home workshop hobby lathe), but alas I did not and I'm charging into this on my own. ***But now also with YOU!*** Many thanks for all of your excellent materials.

Hi Blondi , a nice summary. R8 collets were designed by Bridgeport for their milling machines (a word of warning for non north american viewers, R8 appears to be much less common than Morse 3 collets) 5C collets were designed by Hardinge for their very wonderful manual lathes ,real hardinge collets are quite expensive. Lathes from the lowest and cheapest to the most expensive and precise have a morse taper in the spindle so Morse collets are an option. (added ) ER originally by Rego-Fix switzerland It is truely international If you use collets on your lathe there is no chuck jaws to run into. running into chuck jaws is a very bad thing.

Cleaning the grit, swarf, and burrs from inexpensive collets sets, when received, can often yield a much better product than expected. I do this underneath a microscope and use an X-acto blade to carefully trim burrs from each cut. The ultrasonic bath may be overkill but I have gotten some grit left behind after the bath.

Nice summary. Only thing I would add for the lesser initiated is that It is important to snap the collet into the closing nut before installing it as undoing the nut is what pulls the collet out. They can be tricky (if not impossible) to remove if you just push the collet into the holder and then screw the nut on over it.
@donaldsutherland244
@donaldsutherland244 4 месяца назад
Thank you! I can't believe that I waited a day to watch this! Two categories of collet not mentioned yet are the square and hexagonal 5C, the oversized 5C's that can be shallow cut to hold thin stock, (watch makers, . . .) and I forget what they're called? -the type that are heated up, to expand, insert tool, let cool and grip the whole of the tools surface area. Admittedly not something the hobbiest will encounter, but knowing of this as a possibility has allowed me to increase the shank of an odd sized drill, and once to make a collet for an old pantograph. I do love your videos and think that you are an excellent teacher! Consider yourself given one apple!

@MichaelKJohnson
@MichaelKJohnson 4 месяца назад
5C collets are good where you need to hold only a very shallow amount of material; the ER collets will close unevenly under that pressure (kind of like using only one side of your mill vice with nothing balancing it on the other end). This can lead to parts slightly canted relative to the spindle axis, resulting in tapered cuts. I run both ER40 and 5C in my lathe (and ER40 more often than 5C), depending on what I'm cutting and why. I also made an adapter to use the ER40 collets as a self-centering "spider" on the outboard spindle end.

Nice idea on the ER spider. ER collets don't hold well on a very short amount of work or tool inside. Had an employee try to get more length on a CNC router ER32 with the result of a tool flying across the shop @16,000rpm.
@Self_Evident
@Self_Evident 4 месяца назад
In order to securely clamp short parts in an ER collet, put a matching diameter (or even slightly smaller) part in the back end of the collet to balance the ER clamping force, just like when clamping a small part in one side of your vice with a similar size part in the other side of the jaws.
@Nemozoli
@Nemozoli 4 месяца назад
Nice comprehensive comparation, Quinn! The only thing I would add - that also puts another checkmark in the ER collet's book - is that they have a "loosen - then - eject" function, meaning the initial loosening of the nut doesn't let the tool or part go at once, you have to turn it a bit more to get it out. It is a nice addition, has saved me lots of endmills NOT falling onto the workpiece or the machine vise. The thing that allows them to do this is an eccentric ring on the inside which fits into the groove at the collet's neck part.

I use ER a lot. Common error is not to tighten the nut sufficiently - look up the closing torque for ER32, it's *massive*. Ball bearing nuts can help with this, they basically have a thrust bearing built in that allows more of the applied torque to be used closing the collet.
@sidewind131258

@@sidewind131258 Depends on the size of the part and the range of the collet. The lower down in the range you go, the more torque you need. And I'm not making up the torque figures: the published closing torque for ER32 is 100 ft-lb (135Nm). That's a lot.

@paullehmor982
@paullehmor982 4 месяца назад
One thing to watch out for on hex collet blocks is their precision on the edges.The sides can be expected to be precision ground, but not necessarily the edges. So, for example, when you clamp a hex collet block laying down on the edge in the milling vise (as is shown in the video), the Y position of the work piece is repeatable, but not necessarily the Z position.
@mpetersen6
@mpetersen6 4 месяца назад
The easy way to fix this issue is to lay a piece of material of a consistent size in the bottom of the vise so that the collet block rests on the piece of material. Not the edges. The best way is to surface grind the edges so that they are all the same distance from the centerline of the block. I made my own 5C collet blocks in arrangements other than the common 4 and 6 sided ones. 5, 7, 8, 9, 10 and 12 sided ones. All were within .0001" using a precision collet.

Great job explaining the differences and the uses of collets. The old guy wisdom I would impart is “Clean your collets, every time”. As you know, collets work using the tapers to collapse the collet and grip the tool or workpiece. (Quinn said so), but I have often seen people using dirty collets, pulling one tool out and slapping another in, or keeping their collets “well lubricated” they defeat the friction that make collets work. I use ISO Alcohol because it leaves no residue. Like anything else in life, you can go really far down the rabbet hole topics like fretting and pull out forces would warrant their own video. (Hint hint Quinn) Sometimes knowing that the long, skinny pedal on the right makes car go is all I really need. Thanks again Quinn, great job!

Excellent video as always, Quinn. Thorough, concise, and delightfully nerdy. Regarding the TTS holders: I'm one of the hobby users that's had much success with them. The "special" collet really isn't that special... You can buy the precision ground one, or you can do as I did, and just grind a regular 3/4" R8 collet nose flat, on a belt sander. The important thing is that the face of the collet is recessed into the spindle, which allows the upper face of the holder to register against the spindle nose. The collet face is not the registration surface. This is what gives you the Z-height repeatability, as well as making up for (most, if not all) rigidity lost due to stickout. I've got a smaller mini-mill than yours, and on the rare occasion I need the extra Z-height, I just hold the tool in the appropriate R8 collet... But I honestly cant' remember the last time I've had to do that. Most of the time I can just swap tools in a few seconds, which is well worth it, for me. (I definitely recommend using the genuine Tormach holders... Unless you're luckier than I am, those import ER collet holders have terrible runout) An added bonus is if your DRO has a tool library. Automatic offset compensation at the touch of a button!

The deckel collet is also used in the deckel mills (deckel FP1 ) The spindle is fitted with a tapered insert which has a morse taper on the outside and an deckel collet taper inside This is done to have the option to remove the morse taper adapter and use bigger tooling for example a 6" shell mill I believe that the flat side of the thread is done to increase the friction on this side of the thread so the drawbar can't loosen itself due to repeated starting and stopping /reversing of the spindle The deckel mills are very stable and easy to use and reliable Greetings from Germany Keep up the great work I learned much from Ur videos

They've come in handy with the collet blocks I bought at the same time. I own both an old milling machine (Clausing 8520) and an old lathe (Logan 10-inch). They have enough wear in the lead screws and ways that I know I'm never going to get great precision from them, so I limit any projects based on that knowledge.

An important point to be aware of is that end mills with a set screw detent must be inserted at least a few millimeters beyond the detent. Otherwise, when cutting at high feed rates the pressure on the end mill will cause it to break. p.s. - You can instruct apprentices on how to do things the right way until you're blue in the face, but I've yet to find a way to ensure they consistently follow directions. I've even had apprentices place double-end end mills in ER-32 collets at such a depth as to break the flutes on the second end.

I have a 6" Atlas lathe and recently purchased a set of collets that work in the MT#2 spindle of the lathe. I fabricated my own draw bar with some grade 8 threaded rod, a thrust bearing, brass busing washers and a knob from McMaster-Carr. The capacity is inch sizes with the largest being 1/2". The utility is limited although it is great for threading rod to make studs, pins, small shafts or finials.

Somd early collet fun for me was when I acquired a Dremel, a rather odd and apparently discontinued model with only one collet that came with it. Thankfully in those pre-internet days we still had hobby shops around and I was eventually able to acquire all four of the sizes that were possible for that thing. :-)

Collets come in many varieties. You have your DA collets for drilling, your ER collets for general workholding, and of course there are Phil collets that can feel it in the air tonight

I checked Finnish and German shops a bit. C5 and R8 collet don't seem to exist here. For hobbyists it's either Morse taper 2/3/4 or ISO40 for the big guns. ER32 for MT3 on mine.

Buttress threads are very common on certain types of industrial machinery. One application is on stamping presses for the adjustment screws used to set closure height on dies. They were also used for the interrupted threads on the breech blocks of large artillery pieces iirc.

Vintage Deckel Machinery is quite common here in Germany. We have companies that entirely specialise in restoring and maintaining old Deckel Milling machines and also still produce the acessories. Deckel clones are also produced by the company FPS.

Also you can use the Deckel collets for tool holding. Deckel Milling machinea have a Iso40 taper and Deckel made Iso40 collets with the same buttress thread aswell as Iso40 adapters for the small and thin collets.

Great video, and very helpful, thanks. I'm hoping to be setting up my first hobby machine shop later this year, and my plan had been to "standardize" on 5C collets. After this, I'll likely start with er-32s, especially since I already have a small set...

Excellent presentation. I've got a 5C "run-tru" chuck for the lathe an it is my go to when I have the correct collet for the work. Useful when polishing right up to the colleet. No edges to snag the hand like an ER has. Also very little of the work has to be inside the collet. I also have an ER40 "run-tru" chuck that I use because of the greater holding range of the collets. My set of 5C collets is by 1/32"s which is too coarse to hold all work sizes. I do have a few square and hex 5C collets bought for a specific use. Other handy things I've got for the 5C is the spin indexer (which I reversed ends on and true the base to the bore so it can be quickly clamped in the mill vice.) The collet blocks I've got originally didn't center the work ±perfectly so I had to take a slight cut on them to get very good results. I've used them on the mill to drill into the end of a rod. Was helpful when I needed the hole to be offset from centerline to work as a cam. I have the R8 to ER40 adapter mainly because I have some metric tooling that my ER imperial collets will closed down enough on to hold. My First set of ER collets were by 16"s, too large of steps and they were a PIA to use because they were really difficult to get snapped in & out of the nut. I bought an import set by 1/32's which are much easier to get in & out of the nut. They run just as true as the name brand set. My 2¢.

As usual an awesome video ! In my line of work we don’t do much more than very basic machining in a mill and I thought I was being clever when I used a collet block to mill a hex on a part little did I know that it’s very common to do that - ahh it was nice thinking I was that clever at least for a while, lol I enjoyed riding that train for a while until I realized that everyone uses them for that purpose, lol

All hail the algorithm. I was looking at collet sets today (and bought a set of ER40s and a collet block set). And now your video is at the top of my feed. I needed the larger collet to hold some larger parts. The mill I use at work (a high school) has ER32 tooling collets. Our CNC mini mill and CNC wood router use ER16s. I hadn’t even thought about the block setup fixing the part centreline in Z axis.

Nice video. I use ER collets almost exclusively. Both on my lathe and mill. ER32 is the go to size but I also use ER16 on the mill for small work as it gives good reach into confined spaces. Also, as someone mentioned above, get some bearing nuts. You can crank them up tightly or if you don't need to hold so tight you don't so much welly for a given clamping force. I also use R8 from time to time for the very reasons Quinn pointed out.
@johnfreiler6017
@johnfreiler6017 4 месяца назад
Great Video, thanks. I would have suggested a moment to discuss machinable collets. Keeping one or two in the shop always seemed to be a life saver when you had something odd and didn't own every conceivable collet size. So, you buy your sixteenths 5C collet set, cheap and common as you noted. then you have a machinable collet for when you discover that you absolutely need to grip that 7/32nds part.

In Europe ER collets are the most common type. I have two sets, one for holding endmills and one for a collet block. Also have a ER32 to MT3 holder to fit in the lathe tailstock. As Quinn mentioned in other videos, not recommended to use an endmill in a drill chuck.
@Galleitch
@Galleitch 4 месяца назад
Might be worth mentioning that although a 1"/25mm hole is technically out of spec for ER32, there are folk who make them - more hole than collet, and I'd be wary if it's something that needs a lot of holding power or high precision but they work just fine. Searching for 25-24mm collets should turn them up.

In my whole apprenticeship I only worked with ER collets so far. On all the mills I worked with, they used swappable collet holders, in which the tool and collet themselves can be left in when swapping tools, so you don’t lose Z and and they are identical for the same collet size class.
