I'll also add, think your proceedure through first, what will happen if things don't go as planned..
I use a 7inch hand held grinder alot, it's very fast, with alot of torque. If it hangs up in the work, I want to know which way it'll try to go, and I want to to pull it's self out of trouble. One I learned from my dad, with a large drill motor, the trigger hand holds it so if the bit binds, the finger is pulled from the trigger, not into it, especially if it's in low gear. Develop good work habits, so it's natural to do the safe thing. I spent 20 years in construction, whenever I laid the skilsaw down, the saw blade pointed away from the body. I automaticly do it now.
