HPD HSSE HSSE Drills Hole Making Tools

• High helix-sharp cutting edges to avoid built-up and to be suitable for high performance drilling.
• Wide flute and stub length-increasing chip removal and reducing vibration and deflection.
• High vanadium HSS-EX material with superior TiN coating - higher speed and feed, longer service life.
• High quality-good surface finishes, high productivity

Designed for drilling in stainless steels, mild steels, aluminium, aluminium alloy, aluminium die cast, copper alloy etc.
