Getting bits out of water-cooled spindle

Postby TD On The Hill » Sat Jul 28, 2018 2:25 pm

Hi friends,

Any secrets to removing bits from the spindle? I loosen the collet, but the internal part stays tight. I'm using the correct collet insert, 1/4" for 1/4" bits. Getting the bit out tends to require more encouragement (with more accidental finger slices) than I'd like. I want to avoid marring any surfaces, and I also want to avoid moving the spindle out of position during bit changes. Other than using gloves and prying it out with other tools, does anyone have a good method? Has anyone else experience this?

Thanks!

I'm using the Shark HD4 extended with water-cooled spindle.

When I first got my water cooled spindle from NWA, I had the same problem. I would have to force the bits out. I wound up buying another collett. It has made life much easier. Still use the original one from time to time.

I will be buying another collet. Which one did you buy?

My workaround: I noticed when taking the tightening nut off, that the collet seems to sit at a slight angle. Some gentle tapping on the shaft of the bit on the high side (the part of the collet that is further into spindle) helps it release.

Thanks!

It has been a couple of years so I can't remember I ordered it through my local woodworking tool/supply store.
