April 27, 2015
Makita introduces the 16” self-sharpening bull point chisel bit with an innovative design engineered to keep the bit point sharper longer than traditional bits. The bit features improved geometry for faster penetration and more efficient material removal. It is for use with 1 1/8” hex hammers, and is ideal for general purpose demolition in brick or concrete, as well as for starting holes in concrete.
