Milwaukee 12v Keyless Chuck +/-

[scratchedup]

Milwaukee is probably my favorite tool maker but these keyless chucks generally piss me off...they just are IMO not up to the job of holding the bits.

This is for the 12v stuff that I have a bunch of.

Generally all is good but one in ten times the bit will suddenly loosen and fall out.

With only 12v there is no way to get enough tightening torque.

Years ago on my big 1/2" M hammer drill I had my tool guy send it back to re-place the keyless for a keyed chuck....HUGE improvement although it took a few months to get back. It was worthless. Now awesome.

Well I've owned the older M12 hammer drill and the new Fuel M12 hammer drill and haven't had issues with either. I wouldn't say they're top end but they have held twist bits, mason bits, spade bits (smooth & hex shank) hole saws (hex) & hex bit holders.

I put them exactly between the Dewalt 18v NiCad (functional but not spectacular) and Bosch (Röhm, top end) among the cordless ones I've used.

The Milwaukee chucks used to be made in Japan by a company called Yukiwa Seiko. I believe they may still be made by Yukiwa, but I'm not sure whether they're still made in Japan, or to the same design. Yukiwa may also make chucks for Makita, and while I like the chucks, I get the feeling from reading some reviews, that the company occasionally screws up on the engineering.

As for your current drill, it probably uses a standardized threaded mount. Once you figure out what the mount is, i.e., 3/8"-24 or 1/2"-20, it's not that hard to remove the chuck and replace it with a different brand, such as a keyed or keyless Rohm chuck from Germany, or an LFA chuck from France, or a Jacobs chuck from wherever the heck they're made nowadays.

If you're just using the power of the tool to tighten the chuck, you're never going to get it properly tight. Push the tightening collar of the chuck towards the back of the tool and ratchet it tight by hand.

I tighten my m12 drill by hand and have never had a problem.

Sounds like this might be operator error on my part...I have never thought to tighten by hand with the tool unpowered!

When I get home I will try this.

Thanks...great advice.
