just purchased my first benchtop mortiser and i love it. well….....except for the fact that everytime I use it the auger bit slips from the chuck. Has anybody else had this problem? any suggestions?

Nope…..never had that problem. Mine works perfect. Check your set-up. I’ve had mine for 14 years, and cut a lot of mortises….Push the auger all the way up into the chuck, then let it drop down about 1/16”, and tighten the set screw on the front. Make sure bit and auger are secured good in the chuck…...

You didn’t mention what kind of mortiser it is….

Make sure you tighten all three places around the chuck.

well still no luck! i took the chuck off today to inspect it and everything looks fine to me. I guess my only option is to but a new 3/8” chuck. any recommendations?

Is this a new item or did you buy it used?

If it’s new, the manufacturer should make it right.

If it’s used, you’ve just had a refresher lesson in “caveat empor…”

Good Luck and …

Are you installing the bit and chisel EXACTLY per the instructions? I just got the Powermatic 701 and had problems until I read and followed the instructions to the letter.

i bought a used craftsman on craigslist. however it looks like it has not been used. when i bought it half of the parts were still in the original packaging. I also am doing what the instructions say.

does it just slip out or does it get stuck in the wood and gets pulled out by raising the mortiser?
i have had the latter happen a few times in very hard wood. Are there deep scratch marks on the bit where it slips from the chuck? if so you may want to sand them smooth, if not you may want to add scratches to give a grip surface.

Also check if there isn’t oil on the chuck fingers.

do you have other size bits and does it happen with those also? if not try with a regular drill bit to see if the problem is the chuck or the auger bit.

I agree with Greedo good advise, one thing I didn’t know was you need to sharpen mortise chisels. Nbeener taught me that one look up sharpening hollow mortise chisels on LJ’s search engine.
