Bought some of those hex drive drill bits the battery drill chucks scuff up your bits so bad when they slip ...an old machinist told me to soak the drill press chuck (jacobs)in diesel fuel just lower it into a can of D.F. for the weekend. Also said tighten all three positions on the chuck ! with diesel lube works good helps protect your number and letter bits !
Just bought a new Ingersoll Rand 90 degree die grinder. My Harbor Freight one still works but does not have the safety lock trigger and was always concerned for an accident to happen. The IR is much quieter and more powerful. So powerful that it shreds roloc discs very easily @ 90 psi. $54.00 on Amazon.
Very timely, I was operating a HF die grinder yesterday with a carbide bit inside the cab. . Set it down on a HF moving blanket and next thing you know leaned on the trigger and it went full tilt, luckily it spun into the blanket and stalled itself. It would of been a mess if I would of hit it directly with my butt cheek. Definitely will be being more careful in the future. Steve
