Irwin HSS Pro Drill Bits

The Irwin HSS Pro Drill Bit in 7.5mm diameter is supplied individually in a PVC tube, providing practical single-bit purchasing for professionals who need occasional replacements for this larger mid-range size. The 7.5mm diameter is particularly suited to heavy-duty construction work, metalwork fabrication, and creating holes for larger fixings and wall plugs. Manufactured to DIN 338 standards from high-quality HSS steel, this drill bit delivers reliable performance across demanding applications. The precision ground cutting edges provide fast drilling with perfect finishing, whilst the ground flute design ensures maximum accuracy and promotes fast chip removal. The universal 118° point shape makes it suitable for drilling alloyed and unalloyed steel, non-ferrous metals, cast iron, and plastics in trade and industrial applications.
