  |
|
|
My bench drill's chuck won't open up fully,i can use small dia bits but when
i try to use any large bit's it just stops turning. Has anyone got any ideas what the problem might be.I have'nt used it much for drilling really but i have been using sanding drums.

Probably just clogged up with crap, if theres nothing obvious.
Spray the chuck especially inside, with some wd40 or similar... work it open and shut a few times, taking it open a little more each time you do it.
If still no joy, undo it as far as possible then put a ring spanner over the chuck key for more leverage.

Does it take bigger than 10mm drill bits, what size are you trying to put in?

I think it goes up to 10mm Jason, but i can only get it to around 5 or 6 mm
at the moment, i want to use my plug cutters to cut some plugs but i'm
stuck. I could use an ordinary drill but would prefer to try and fix the bench drill.
Good point Hitch,it's probably full of M.D.F. dust as that's what i was sanding ( jigsaw pieces for my grandson).I'll try again as soon as i can get in the workshop. Cheers lads.

Finally got round to looking at the drill, (well actually i needed to drill a 7mm vertical hole in a piece of wood) so i tried to see if i could fit the bit in the chuck and the bloody thing opened up fully
Happy chappy.

dont forget they're usually easy to swap for another sometimes larger or keyless.... usually have a opposite threaded screw inside the chuck, which unscrews (pushing upwards) in an anti clockwise direction. which you remove, then put the chuck key in and knock it clockwise with a mallet, sometimes with force to give it the quick jolt, this should allow the chuck to unscrew and be replaced.
regards keyless chuck's, buy a cheap cordless drill or use from a knackerd old one you may have laying around, usually cheaper to buy one than buying the keyless chuck on its own...
yeah i know you pay for quality before anyone saids it...
above dont apply for morse taper drill presses tho, they're usually industrial...
make sure this is all done with the drill press unplugged...

Chucks fitted to mt shanks are easy to change. they are fitted on a taper, aswell. A shallow wedge with a split get them off no trouble. Theres the odd occasion when you need to heat the chuck up though
Not a fan of keyless chucks myself, unless they are top quality ones.
In my line of work, nothing like doing a chuck up by hammering the key round or putting the end of a spanner over it.
I find if a drill snatches and locks up in a cheap plastic covered chuck, you half kill it trying to undo it.
