Heavy Duty Drill Bits for generally large diameter hole drilling needs. HSS Drill Bits are for Metal or Wood Masonry Drill Bits are for Cement or Concrete. 16mm and 20mm Masonry Drill Bits are tapered to fit most Impact Drills. The Masonry Drill Bit size 20mm can be ideally used when trying to penetrate a 1/2" or 20mm diameter pipe through a wall instead of chipping or breaking concrete material. In this manner, the penetration is cleaner and requires less or no repair at all.
