CoroTap 200 Spiral point tap

Spiral point taps push the chips forward and are used for through holes. They have the strongest tap design due to shallow flutes. The flutes are only used for cutting fluid, not for chip evacuation.

Features and benefits

  • Chamfer B (3.5-5 threads) for high process security
  • Edge treatment for reduced axial force and torque makes the tool run more smoothly, reduces risk of cutting-edge chipping and improves surface quality, tool life and chip formation
  • High speed powder steel taps for improved strength, wear resistance and tool life
  • Different coatings and grades are available:
    • CoolTop coating combines high hardness with good wear resistance
    • SmoothTop coating for low friction and adhesion
    • Steam Temp An oxide layer protects the surface, act as a good carrier of lubricants and prevents cold welding and built-up edge
