Head coating

Solid carbide high-performance deep twist drill bit

• With optimised shank diameter tolerance for use as a holding fixture in power chucks and hydraulic expansion chucks
• 2-facet grinding
• Cutting material: ultra-fine grain solid carbide, TiAlN-coated (head)
• Reliable chip flow even with tough and long-chipping cutting material due to
  adapted drill bit profile and large chip chambers
• Four guide chamfers for precisely aligned bores with good quality surfaces
• True-running accuracy of the tool when clamped max. 0.02 mm
• Pilot hole recommended
