Duff chuck - fixable or time to replace

Here's the place to talk about all your table saws, bandsaws, routers and dust extractors. In fact anything that makes noise and uses electrickery.

Duff chuck - fixable or time to replace

Postby RogerS » 05 Nov 2014, 17:51

I have a couple of Makita battery drills. The drill chuck redefines 'Not Fit For Purpose' as both are incapable of guaranteeing the drill bit stays where it should securely. Unlike the Bosch drill chuck on my mains drill - which, once you've tightened it up, further turns just seem to ratchet over on something - whatever - the thing is drill bits stay secure. On the Makita, there is no such ratchet mechanism and so nothing to tighten up 'against' as it were. I've tried holding the chuck in my hand and then spinning it closed under power but that doesn't work very well either. Very difficult to do with smaller bits as well.

So basically these drills are doing my head in. But before I start the long hard trek of choosing something else (My God..have you seen how many variants there are out there :o ) is there anything else I can try to make the chuck usable?

TIA

In my experience the only decent chucks are Rohm and Albrect and found in precision engineering with prices to match.

The ones on my Hitachi drill/drivers are just about acceptable but work loose when removing screws. Don't know the chuck maker

I'm just about on the point of fitting keyed chucks as about the only truly acceptable engineering solution IMHO

Hi Roger,

This is probably too late now, but there are two excellent posts on the ITS site explaining the DeWalt and Makita drill variants in great detail.

This is the DeWalt and this is the Makita.

Richard did a really good job.

A useful link, thanks, Neil.

However I am now the very happy owner of a Festool CXS :D

Yes, I thought that I'd read that you had bought the Festool, glad that you're enjoying it.

I surely am. It fits in the hand perfectly and the angle adapter is very handy. Just oozes quality.
