CoroTap 200 Spiral point tap

​Spiral point taps push the chips forward and are used for through holes. They have the strongest tap design as a result of 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, acts as a good carrier of lubricants, and prevents cold welding and built-up edge
