Thank you once again, Dr. Nubs! I've been aware of so-called "self-releasing" collets, but I have never understood how they actually work. I also thought all modern routers now have them. Thanks to you I have been released from my appalling ignorance, and am now pulled up into the light of knowledge. It feels great! We don't pay you enough.
Thank you you just saved me from buying a new router have a Craftsman that I bought at Sears but Sears is no longer around nobody seems to know anything about a colic Departed router bit goes in I have a quarter inch I need to put in a half inch bit you can pop it out and put a new half engine to replace the quarter-inch it'll do both I did not know that thank you so much you helped me so much I watch all your videos I've learned a lot keep the good work current website
I always thought it was the universe telling me that I suck... This explanation is much better. Maybe Stumpy can also explain why it often takes 3 tries to push in a USB connector even though it only can be turned in 2 ways.
I have a Bosch router in a table and a 2.2kw spindle on my CNC with an ER20 collet. Both of them did this and it has always driven me nuts. I finally learned to keep a hold of the wrench until I'd loosened it a 2nd time. And now I know why and that kind of makes me happy. Thanks!
Yeah especially on the CNC it's super annoying because sometimes the cutter just falls straight out after the second loosening and if it falls onto the machine table, there's a good chance you'll break part of the flute (especially on the aluminum cutters with a single flute) or damage the tip on a chamfer tool.
There have been so many people online complaining they cannot get their router bits out. Explained they have to loosen it twice. I can now reference this video. Thanks.
Not only a Master Woodworker but a tooling Engineer as well. These vid's illustrating tool construction are invaluable in showing that the idiosyncrasies of many tools are there for a reason. The lesson! Make sure your tool isn't faulty before you send it back or; God forbid; try to mend it.
HA!! Awesome tip!! All this time I thought I was doing something wrong. I don't remember reading this in the Operator's Manual either. Thanks so much for sharing. 👍🏾
you have restored balance to the universe! I can usually intuitively figure out why tools do certain finnicky things, but I was never able to nail this one down. You are so good about instruction on the little things no one else ever brings up
I was just thinking about this the other day while using my router - I figured there was a reason you had to perform a two-step. Well, thank you very much for explaining why! This was great.
I've been puzzled by this ever since and have been really interested to know why and never even thought I will ever know. Never I ever expected that the explanation will come this morning.
Thank you for video. Something my father taught me was to set the wrenches 🔧 up so you can squeeze them with one hand. This is to tighten and to loosen them. I have seen too many times when you are especially loosening the collet your hands swing wildly and could hit or scrape something and you now have a injury. Same with tightening, however you usually slip and hit your hands 🙌 together.
I too had thought I had ruined my collet the first time I used it. But after a close examination of the bit, collet and shaft it all looked fine. After your video it all makes perfect sense. Not that I was losing any sleep over this. It is good to know why something works the way it does. Your videos have made my woodworking time more enjoyable and safer. Thanks a lot for your knowledge and keep up the good work.
I have been using collet sets on metal lathe and milling machines since I started a toolmaking apprenticeship in 1967. On lathes you usually have a draw bar that pulls and pushes on a sleeve that passes through the spindle for the collet to screw into, so you can change the workpiece in just a few seconds, plus they go down to sizes that a chuck couldn't grip, and are kinder to the workpiece leaving no marks on softer materials like brass. Collet sets on milling machines work exactly the same way as described by James in this video, and need the second pressure to release the cutter. Anyone owning a smallish hobby mill will know that you can get collet sets for crazy low prices from Wish and Bangood (about $80 for an M2 collet chuck and a dozen collets from 2mm to 20mm) and they work (almost) perfectly. That is to say they clamp the work piece but some of the collets didn't snap into the collet chuck without some minor work with a fine grit diamond plate.
Thank you so much for this little nugget of info. I've been wondering to myself why this happens with my router and if there is something wrong with the collet or shaft. There was a little ah ha moment realizing that the collet is like a small version of a Morse taper used on drill presses or lathes.
Mind = blown! I honestly thought I had a mildly defective collet all along and I was encountering a spot where the threads were rough and imperfect. Clearly I never looked too deeply.
Once again you've produced a clear, concise, and useful video. Thank you for sharing your knowledge! Hope the lake effect snow peters out before it reaches your burg. Not too bad in Mecosta country so far.
These are ER style collets that are used in the machining industry. If you measure the outside diameter of the largest part in millimeters then you know what size they are (ER-20, ER-25, ER-32, etc) That makes replacing them pretty easy.
Thank you, as always. Can't help but wonder why this bit of valuable advice isn't in the user manuals. And thanks for the additional router info links.
if your bits get constantly stuck, it could also just be a terrible surface finish on the collet. i had it on my makita palm router for example. every bit got stuck and i had to bang them free. the ruff surface grain basically starts to lock together and thats what keeps it from releasing. You can simply sand a smoother finish on the collet and the connecting surface. if the grains cant interlock, they wont get jammed. i sanded it on 400 and 1000 grit and have not had a single stuck bit afterwards.
My makita trim router has the second type of collet you mentioned. It does tend to get difficult to get the bit sometimes. I have found that giving the parts a good cleaning reduces this problem a great deal. I soak a few minutes in a solution of laundry soap and water, give a gentle scrubbing with whatever i can get in there ( a pipe cleaner today), rinse well and set to dry on some warm surface to be sure the water is all dried up.
The pre-self-releasing PC collets were a royal PITA to release! One way is to not bottom the bit out when installing the bit, and then try tapping the bit in when trying to release it. This is the way I have to do it with my Dremels.
I'd noticed that double tightness and wondered about it. I'm pretty sure my Dremel uses the shaft-integrated style too. Very nice to know the difference.
Recently replaced a dewalt router, and it came with like a combo collet..its like 2 sleeves in 1. Used a 1/4 bit, but when I went to remove it, the sleeve came out with the bit.when that sleeve is out, you can use 1/2 inch bit..was a little leary, but so far so good.
Thanks for a simple explanation, James. My hobby woodworking has become more CNC-centric over the last few years and I now deal with routers a few times per week, so this issue shows up regularly. One less thing for me to ponder while the CNC does its thing.
A somewhat related issue I've seen people run into, is where they are suddenly unable to get a bit to fit into a collet that was previously fine. In 9/10 cases, it was because they tightened the collet without a bit in the router. They did this to secure the collet firmly to the router after use, in an attempt to 'keep it safe and make sure it doesn't go missing'. Without the shank of a bit to provide resistance, the collet is compressed until the hole is narrower than the shank diameter it was designed for.
I never investigated how it works. I just blindly accepted that I have to do it twice on my crapman (craftsman) router. I probably would've pay more attention had it been a more expansive one. LOL. Thanks for explaining. Now I know it's not so crap anymore. haha.
Good vid, you should make a video all about how one should read the manuals for tools and how not to always follow them but read them none the less because some are invaluable. The first router I ever purchased had split ratings no middle ground most of them said they had to use pliers to remove the bits mangling them. So i found the digital manual read it and said to loosen the collet twice. I've had my Hitachi 2.25hp router for 5 years now after picking it up for 99 bucks with all the accessories brand new likely due to the vendor having to do a sale to move inventory due to the 3 star rating at the time.
Wow. I bought a Triton just a couple weeks ago and it was my first exposure to this very thing. Ive been curious about it but both collet nuts do the same and it is not crunchy so I figured it was some kind of feature.
Nice bit of info, I always like knowing exactly why something works the way it does 👍 I've bought an adapter which will allow me to use ER20 collets with my 1/2" router, meaning I can now use any size of bit rather than just a few sizes. I'd bought a full set of ER20 collets to go with a spindle I bought for building my own CNC ... I wasn't paying attention and didn't realise the size of it and that it weighed 5Kg, so needless to say I've not built the CNC yet!!

EVERY SINGLE TIME I loosen mine and hit that second spot I think "I bet stumpy knows why"

Yes he does :D on my side I'll be less frustrated by this thing
Thanks for absolving me of the worry that something was wrong/cross-threaded with my router’s collet!
I've wondered about this for decades. Thanks for revealing the inner truth. Keep 'em coming!
Phew!!!
After wondering if there was something wrong with my collet for the last 3 years you have in 3 minutes put my mind at ease.
Thank you.
Thank you; I’d never bothered to look into why it always does that. Makes perfect sense now!

My DeWalt 20V trim router does the same thing since it has the self-releasing collet, too. I think this is a pretty common thing nowadays.
What collet size for 12mm Router machine? Er20 is compatable for 12mm Router machine?
@@manzerasobrado6045 ER20 will work for a spindle, but not a router. You'll need to look for a 12mm collet specifically for a router.
@@dgoddard my Router machine is 12mm
What collet size for 6.35 bits
An outstanding video! Nothing like learning something useful in 3:28! Thanks so much!

Thanks so much ! The "turn a 2nd time tip" at 2:06 worked like charm, after having tried other suggestions for 15 minutes...
Another of life’s mysteries solved. Thanks lad.
Great info! I had wondered if I had somehow jacked up the threads on my router. My doubts have been erased! Thanks.
Pretty interesting indeed! Thanks, James! 😃
Stay safe there with your family! 🖖😊
Always wondered why this happened!
I always assumed I ruined the collet the first use by overtightening it. Thank you!
And I wondered if I was over tightening my collet - thanks for the explanation and new found peace of mind!
I discovered this a long time ago. It sure makes removing the bit a lot easier.
I love your explanation!!!! Very good and very understandable!!
Thank you ❤

That makes so much sense now! I always thought the threads on mine were messed up!
Bruh I literally asked myself this question yesterday when I had to loosen it twice. THANK YOU!
Thanks, James! The clarity helps 😊
Thanks for clearing that up for me James. You're always amazing!
Always wondered what was going on changing router bits. Thanks.
Thanks!!! That has driven me crazy for years.
My PC 690 has done this from the day I got it in 1992. Now i finally know why. Thanks, Stumpy.
Perfect, I noticed that but never stopped to really think about what was happening. Another mystery solved! Good one, thank You
Again, enlightened! Thank you!
Thank you for explaining this! I came so close to returning my 1st router for a replacement, thinking it was defective.
Interesting! My old 1 3/4 HP Craftsman router works the same as you demoed. My Dewalt only needs to be loosened once to get the bit out.
My makita trim router has the second type of collet you mentioned. It does tend to get difficult to get the bit sometimes. I have found that giving the parts a good cleaning reduces this problem a great deal. I soak a few minutes in a solution of laundry soap and water, give a gentle scrubbing with whatever i can get in there ( a pipe cleaner today), rinse well and set to dry on some warm surface to be sure the water is all dried up.
I have nothing to say really, but I appreciate your content, and wish to help with the yt-algorithms.
Thanks for the video, always enjoy watching!
I always just thought my router was old... Bought it used and it's always done this. Now I know why!
THANK YOU!!! I have wondered about this for a loooooong time.
THANK YOU! My Shaper Origin always made me wonder why I had to loosen it twice. Love your channel!
And I thought it was just me! Thanks for this great simple little info vid!
The pre-self-releasing PC collets were a royal PITA to release! One way is to not bottom the bit out when installing the bit, and then try tapping the bit in when trying to release it. This is the way I have to do it with my Dremels.
Thank you! I thought I was doing something wrong for YEARS!
I have always wondered why this happens. THANK YOU
My Bosch does this and I always wondered if something is wrong with it. Now I know. Thanks for this clarification.
For this great tidbit, you deserve a cold one my friend!
I was just wondering about this, this past weekend. Thanks for the info!
Thank you. I have wondered about this ever since I got my router.

So THAT's why. Thanks again, James.
Great information James. That does help getting the bits changed. Stay safe and keep up the great videos. Fred.
Thanks James. Didn’t know that was a feature on my Bosch 1617. I don’t recall this mentioned in the instructions. I’ll check it out again.
Always wondered about this. Thanks for the info.
I'm glad I asked about this. Thanks for doing the video.
man i was about to look for a replacement collet for my PC lol! Thanks James!!!
