The Walter Prototyp Paradur® HSC is a new high-performance solid carbide tap for creating blind-hole threads in steel materials. With its special cutting geometry and reduced helix, this precision tool guarantees excellent chip breaking, even when working with long-chipping materials. With a concentricity of less than 10 µm, this tap guarantees excellent thread quality.

Facts and advantages:

  • Special micrograin carbide with high wear resistance and cutting edge strength, optimized for toughness
  • Graded TiCN multi-layer hard material coating for extremely high cutting speeds and a long tool life
  • Minimum production costs per thread thanks to 3-times higher cutting speeds in comparison to HSS taps
  • Fewer tool changes and optimum machine output resulting from significantly longer tool life
  • High degree of process reliability thanks to perfect chip breaking (no bird nesting) in higher strength materials and hard machining operations
