3 PIECE CORE CUTTER SET
25mm length rotary cutters. Set includes 14, 18 & 22mm endmills and centering pins.
Evolution endmills are guaranteed to perform better than endmills made of HSS, Cobalt or Tini coated. This is because...
Tini coating on HSS endmills increases the cost of the end mill, but only improves its appearance.
- HSS M-2 endmills can only be heat treated to 64 RC before they become too brittle.
- Cobalt endmills can only be heat-treated up to 66 RC before they become too brittle.
- Evolution Premium endmills can be heat-treated up to 68 RC and still have a hardened hardness.
A higher RC rating without brittleness means more holes drilled per pass.
