Keyless Chuck Loosening Problem.
I use a Hitachi DV 18DGL battery drill for a lot of my work. It is very good and the battery lasts a long time and charges up quickly when needed.
BUT, when in use the keyless chuck comes loose and the drill bit does not turn due to a poor hold. I have two of these drills and the same problem exists with both chucks. Is it a design problem or a bad batch of chucks? I do not know. Other makes of keyless chucks that I have used over the years hold the drill bits securely and do not come loose even if using a hammer action.
Is there a solution? Perhaps I should pour some fine sand into the chucks.

I have the same problem with the Makita,and have put it down to the sudden braking action if the trigger is released quickly.
Have noticed if I let the motor slow down gradually,the chuck stays tight.
Regards,HzBlinkin Ek! This is getting scientific and now includes physics. I should have listened more attentively during "science" lessons at school I think. Perhaps that Newton bloke is involved.
