Can a chuck be straightened? Wobble in the bits

dimanche 6 avril 2014

Help! My bits wobble!



Ahem.



Anyway, I have a Trade Tools RI170 with a keyed chuck ( http://ift.tt/1e1WKyB ). The whole shebang is second hand. I have good reason to trust it hasn't been abused as the dude I bought it off is an army engineer who made, well, everything metal for them. He had 3 and needed space as he was forced to move.



The bits I mount wobble. Drill bits, fortner bits, etc. I took out the chuck and noticed one of the three teeth/grippers had a slight dink in it. I must have done it as the wobble seems to be new.



It's a small wobble, about 1mm on the end of a 10cm long drill bit, but I'm keen to see this zero'd out.



So, am I up for a new chuck (I don't mind) or is a chuck somehow resettable so it grips symmetrically? Jam a drill bit in it in reverse or sand it with wet/dry on a shaft?



BTW, I've noticed the teeth/grippers are a bit wobbly until tightened. I wouldn't say it's worn, but it does strike me as somewhat un-machine-quality-worthy.
