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)
