Drill bit web thinning.

I have the Oregon brand chain saw grinder once ZI somehow odored a new grinding disk for it that had the RPM miss labeled I turned it on and was just getting started to make sure it was running true when it exploded even with the guard in place a large chunk was embedded between my 2nd and 3rd fingers, Hurt like all heck I pulled the piece of disk out of my hand only to find it had penetrated over 1/2" between the knuckles. so that caused me to decide to go to the emergency room to make sure there was no more debris inside. There wasn't and the doc said that he didn't want to stitch it up just pack the wound and let it heal on its own. I could have done that after all I had already done the clean out and disinfecting with a hydrogen peroxide betadine solution the only thing I didn't have was the ability to x-ray
I rarely use my saw grinder and only for sharpening the chains but I can see how they could work for what you mentioned, They just seem a little dangerous to me now even with the 10,000 RPM disk that I bought for it.
just gun shy I guess.
