Milwaukee Self-Sharpening chisels provide longer life and increased productivity during general demolition applications. The extended feature length at the tip of the chisel enables up to two times longer life compared to standard chisels and up to 30% longer life compared to other self-sharpening chisels. The self-sharpening tip geometry helps the bit maintain its shape throughout the life of the chisel providing increased productivity by breaking up the material more effectively. High grade, forged steel enables increased durability in abusive, concrete applications. Milwaukee SS SDS-Max 1" x 16" Flat Chisel 48-62-4252
