Drill Chuck Removal

Can anyone help? I have a Black and Decker cordless drill, model EPC188.

This performs and does everything I want it to. Problem is the useless keyless chuck. It won't even hold a 3mm masonry drill when the hammer is engaged.

I have removed the screw from inside the chuck.

There are two flats behind the chuck that require a spanner on each. however the screws that hold the front plate to the body partially foul the body flats and the chuck flat is only 2mm deep. the total gap between chuck and body is 5mm.

How do I get the chuck off?

Chuck an allen key and then give it a sharp whack with a hammer.

Been there done it. Didn't come off. This may be a silly question but is the chuck on a left or right hand thread. Do I need to grit my teeth, become an animal and really give it one?

[Michael Cox 1Participant @michaelcox1]

Normally the screw in the chuck has a left hand thread and the chuck itself has a normal right hand thread.

Hi, I agree with Mike. The best way to remember which way they come off is while the drill spindle is held stationary, the chuck will rotate in the same direction as a nomal twist drill does when you are drilling.

As mike says chuck the sort end of a hex key and give a good sharp blow to the long end. It is best to use the biggest long reach one that will fit in the chuck and holding the spindle still with a spanner, use a mallet rather than a hammer if you have one and don't forget to use eye protection at the very least as the keys can shatter when suject to impact. A full face visor would be a better option.

Regards Nick.

Thanks gents, Used a 3/8 allen key and a mallet. no go. Decided to be an animal, laid drill flat on bench with chuck overhanging and gave it a whack with a 7lb mawl. Its off. All I have to do now is find a key chuck 3/8 UNF. Google here I come unless you know better.

Hi Ray,
Do a search on Ebay for "chuck 3/8 unf" and you fill find a good selection.

Les, try and get one with a solid body, not the type with the thin pressed steel body, these ones seem to tighten better, and they are easier to strip if you need to overhaul it. Not all chucks are drilled through for the L/H screw, and without that, working the drill in reverseis a no no, just try unscrewing a screw. Ian S C
