LS End Mill for Difficult-to-Cut Materials

Purpose-Built for Titanium, Superalloy and Nickel-Based Alloys

The LS End Mill for Difficult-to-Cut Materials is a dedicated cutting tool series developed for titanium alloy, superalloy and nickel-based alloy machining. A brand-new cutting edge geometry is paired with CrS coating at Hv 3200, delivering high heat resistance and low friction in demanding cuts.

  • Unequal helix structure effectively suppresses cutting vibration
  • Unequal indexing improves workpiece surface finish and extends tool life
  • R tolerance ±0.005 for ultra-high-precision cutting edges
  • Ball-nose style suited to precision machining of complex profiles

Ideal for precision production in the aerospace and medical industries.

Highlights
Key Advantages
  • Special edge shape keeps a sharp cut in tough alloys instead of rubbing and work-hardening the surface
  • Unequal helix breaks up chatter so you can hold tolerance on deep pockets and thin walls
  • Unequal indexing spreads cutting load, which shows up as better surface finish and longer tool life between changes
  • CrS coating at Hv 3200 with μ 0.1~0.2 handles the heat and friction that come with titanium and nickel alloys
  • R tolerance ±0.005 means the ball radius you order is the ball radius you get — critical for contour accuracy
  • Ball-nose geometry reaches into complex 3D profiles without secondary finishing operations
