Think - Am I doing something stupid?
I caught one like this right in the chicklets and nose. I was using my Porter Cable R/A angle drill. It's an 8 amp so there is way more torque than my Milwaukee R/A has. I weigh 185 and it has spun me before in green lumber, etc. so I knew better...
Anyway I was drilling horizontally with the 2 9/16"' self feed bit and the drill l extended in front of me just above my waist.... since I have learned not to lean into my work with my face and that tends to be what we do..
Because I was drilling sideways my grip wasn't as firm. It still kicked easily when I caught a knot.
Fortunately I was wearing a dust mask which contained the blood from my nose but I ended up with a blood blister inside my upper lip shaped exactly like my front teeth...which is batter than cracking them loose...
As a result with the big drills I tend to brace aginst my hip now whenever possible and use a taller ladder so I can have the drill away from my face in higher locations.
