• Enables up to 40% faster drilling rates and 50% lower feed pressure compared with standard HSS bits.
• Two cutters and two flutes ensure rapid chip evacuation, reducing heat build-up and prolonging bit life.
• Compatible with alloyed and non-alloyed steel, stainless steel, cast iron, cast steel, and acid- and heat-resistant steels.
