How Not To

Step 4Battery Drill Danger

Battery Drill Danger
A friend was helping me out, drilling some holes in a bench to attach a vise.
She was using a battery drill, the kind with a heavy battery on the base of the handle.
The bit bound in the hole and the drill spun around, whacking her in the head with the battery.
Hard.

Drill presses are famous for swinging things around and hitting people or gashing them, but it hadn't occurred to me that a battery drill could do that too. I guess battery drills are a lot stronger now than they used to be.

She's okay now.
Be Careful.

True story: I was using my 24volt Black&Decker to enlarge the hole in a buddy peg for my kids bike. I had the buddy peg in my left hand with a pair of large vice grips, and was holding that tight against my leg. I then had the drill in my right hand with a 5/8 drill bit. The bit snagged in the hole and torqued the drill around so hard that it literally broke my hand. Nice loud snap. It was a spiral fracture in the ring finger tarsal, the bone that goes across the back of your hand from your wrist to your finger. It hurt pretty good for a while...

FYI, I still don't own a bench vise or a drill press. Anyone want to give me either?

A WorkMate bench is a pretty economical and portable alternative to a bench vise. It makes drilling & cutting stuff (especially round stuff) much easier. And WAAAAYYY cheaper than an ER visit.

One time I was drilling into plastic with very sharp edges and the drill bit got stuck and made the plastic start spinning. It put a large slice in my chest

Ouch. Frequently back the drill bit out of the work to clear shavings which can bind the bit. Keep the bit at the same angle for the whole cut. Faster speed can throw the chips out more efficiently. Not saying she didn't, but while we're on the subject.
