Why choose it

The cobalt-alloyed HSS-E steel provides high heat resistance and wear resistance, extending tool life when drilling alloyed and unalloyed steels, stainless steel, cast iron, non-ferrous metals, and plastics. The fully ground flutes ensure smooth chip evacuation and accurate hole sizing.

Ideal use cases

• Drilling large holes in steel plates and structural components
• Machining stainless steel and cast iron in industrial settings
• Creating precise holes in non-ferrous metals and plastics

Good to know

The bright surface finish reduces friction and helps prevent chip welding. The Morse taper shank MK4 allows quick tool changes and secure clamping in matching machine spindles.
