H3P Drilling Heads

        • Available in the drilling range of 12-25.9 mm (.472-1.02”)
          diameters with 0.1 mm (.004”) increments
        • Single type geometry suitable for both ISO P
          and ISO K materials
        • H3P drilling heads are made from IC908 TiAlN PVD nano
          layer coating grade, for prolonged and predictable tool life
        • Unique wavy and honed cutting edges enable best chip
          form and easy evacuation process
        • Patanted concave cutting edges enable smooth
          penetration, excellent centering and stable drilling process
        • Patent-pending robust and precise chisel point and gash
          angle to withstand high cutting forces (Fig. 1)
        • 15° corner chamfer increase wear resistance and
          strengthen the cutting corner (Fig. 2)
        • Unique dovetail clamping to prevent the head from being
          extracted from the pocket during retraction
        • Wiper land to strengthen the cutting corner (Fig. 3)
