Black and Decker hammer drill

[Michael Brett 1Participant @michaelbrett1]

I have a Black and Decker KR100RE 1000W hammer drill. Drill works fine but chuck is knackered. First problem is I cannot remove the chuck. I have taken out the screw which holds it on but chuck still not moving. Second problem is finding a stockist for spare parts. Do I have to think of buying a new one, I hope not as this has been a good drill up to now.

Any ideas folkes.

Replacing chuck

[bernard towersParticipant @bernardtowers37738]

I would have thought if your locking screw was LH the chuck is 3/8 or 1/2 RH UNF. put a piece of bar in one of the chuck key holes arrest on the bench and give the bar a good whack it should loosen your chuck.

Not familiar with your drill and it depends how old it is ? However all the ones I have has occasion to work on the chuck is fitted on a right hand 3/8" UNF thread several had a screw inside the chuck body to lock it in place — hope this helps

If you have a cordless impact driver, put a 50mm driver bit in the impact driver, then tighten the drill chuck on the same hex bit, always takes them straight off for me.

In my limited experience, it is likely to be a 1/2 x 20 UNF main thread, locked for reverse running by the central L H screw.

Once that is out, the usual brutal method is to insert the chuck key and git a hearty wallop in the direction to unscrew the chuck.

A replacement chuck should be available.

I got one, a Jacobs, (From a local hardware stockist ) for my big Bosch pistol drill, from a local stockist.. So any Black and Decker or Bosch stockist ought to be able to supply a replacement.

Rather than hitting the chuck key to loosen the chuck which tends to knacker the holes, I use a big allen key in the chuck. Lock the chuck on the short end and hit the long end with a lump of wood. Works for me but, I like the idea of the impact driver.

Thanks for help. I did not realise chuck was threaded on, chuck is now of and am looking for replacement.

Not sure if this idea is applicable. I was given a really good cordless drill with two good battery packs and a badly damaged chuck. The original owner had made thing worse, as he had mangle up the screw head, so out came the angle grinder. I did a bit of grinding every day for 10 minutes or so for a week, slowly slowly as things get hot. Got there in the end, and bought a new chuck. You might like to try my idea. John

I know that you have now got it off but I use the same method as Sandy put the largest allen key that will fit and tighten it up and then give it a good tap to release that is assuming that you can tighten the chuck .

You could put the drill under a drill press and try drilling the screw head off.
