Very sharp and aggressive. Second weld in it jumped around, broke 3 cutters off. Stil drilled a whole floor pan out of a Chevy truck bed and half of the replacement bed floor. It was cutting fine still, but I let it walk and broke the last tooth. Replaced with a new cutter, and practiced better drilling technique. That one has done over 100 spot welds, and still cuts great.
