Irwin HSS Pro Drill Bits

The Irwin HSS Pro Drill Bit in 16mm diameter comes individually supplied, offering convenient single-bit purchasing for professionals requiring this larger heavy-duty size. The 16mm diameter is perfect for heavy industrial fabrication, structural engineering, and creating holes for large anchors and through-bolts in demanding construction and metalworking applications. Constructed from high-performance, high-speed steel to DIN 338 standards, this drill bit features a 118° split point shape for increased performance and very good centring. The drill bit ensures precision starting with no need to pre-punch or pilot drill, and penetrates the material quickly, requiring little effort and feed pressure. This reduced shank design is suitable for many trade and industrial applications in alloyed and unalloyed steel, non-ferrous metal, cast iron, and plastics.
