Keyseat cutters slot parameter matching:

Slot width: The width of the tool needs to be equal to the width of the bottom of the T-slot (e.g., when machining 8 mm wide slots, use an 8 mm wide keyseat milling cutter).

Pick the coating according to the material to be processed:

  • Steel / cast iron: TiAlN coating (wear-resistant, high-temperature resistant).
  • Stainless steel: TiCN coating (anti-sticky chips).
  • Aluminum: Uncoated or nano-coated (reduces coefficient of friction).

Roughing: Choose 2-3 flutes (fast chip removal). Finishing: Choose 3-4 flutes or multiple flutes (high surface finish).
