Input: Text: i was installing a fence for a customer and drilling holes through a concrete slab with a very large hammer drill with a 1-1/4" three foot bit. 

leaned over to check my angle and caught a piece of rebar with the bit. it didn't disengage like it is supposed to and spun the whole damn thing around right into my jaw. 

that shit hurt so bad. felt like a blinding migraine for about 15 seconds. stayed on my feet like a champ. unless i'm dead and reddit is hell.

TIFU by punching myself in the face with a 3/4" hammer drill.
