The bits for the router when using the Leigh dovetail jig have 8 mm shafts. With the jig they send an adaptor to convert a 1/2” collet to an 8 mm collet. I put that adaptor into my collet some time ago. Now I want to remove it so I can use router for another purpose. I cannot get it out. Does someone know the trick to get this adaptor out or do I need to buy a new 1/2” collet?

Rich I have the same Leigh jig setup with both 1/2” & 8mm cutters & I had to change collets all the time so I just bought a spare to simplify the process. Is it a dewalt router where the collet pushes into the nut & snaps home, or is it a sleeve? If it’s a sleeve type you may have to completely remove the collet nut & tap it out with a drift & screw it back on again

Trevor,

It’s a Festool router. I have completely removed the collet and attempted to tap the adaptor out. No go. I guess I could just hit it harder with a mallet but I fear doing some damage.

I don’t know what you mean by a “drift”.

Hi Rich sorry to take so long getting back it’s the time difference, You didn’t say if it was a split sleeve type adaptor or not. I used to be an engineer & the term was used for a piece of bar sightly smaller than the piece to be removed. Assuming it is a sleeve (the type with 8mm bore 1/2” outside diameter & slits down the sides)Just cut a dado about 5/8” wide in a piece of scrap say 6” long sit the collet nut face side down on the dado, then take a piece of steel / brass bar (“Drift”)7/16” diameter & sit it on the back of the sleeve Then tap the drift with a hammer it gives much more direct driving force than a mallet which soaks up too much of the shock.You may have to hit it quite hard but the “Drift” will punch the sleeve through & into the channel of the dado. Collets & adaptors often come from new with a light coating of rust inhibitor on them which should be cleaned off before use it turns into a kind of gum with sawdust etc& temp changes that maybe what has “glued” it in. Good luck & let me know how you get on
Best

Old tricks. Soak in WD-40 for an hour. If that doesn’t work, dry it off, then heat the outside one with hot water or lightly with flame. (no flame around WD40)

Use the same principals for opeing new jar lids, etc….................

While you are waiting, order a spare 1/2” collet…............(-:

I’m with Jim.
I had that problem and the soaking in WD-40 worked for me.
I also like the idea of keeping that as your dedicated 8mm collect router and getting another router…:)
