Achieving accurate holes with long tool life is due to the low wear, thrust and stable cutting action. Sutton VA Carbide drills are the ideal choice for the toughest of applications.
Helica is a multi-layer AlCrN based PVD coating optimised especially for carbide drills. Helica wear at the main cutting edge and margin is markedly reduced in comparison with conventional coatings.
The outstanding oxidation resistance and hot hardness of the coating also contribute greatly to stability at the severely loaded cutting edge corners, while the improved toughness of the multi-layer structure significantly reduces the tendency towards cracking.
• Solid carbide material ultra micro grain.
• Balzers Oerlikon ‘Helica’ coating for maximum tool life.
• Optimised flute and point geometry.
