Product Spotlight

Application Alloy Steel, Tool Steel, Cast Iron, Stainless Steel, Titanium Alloys, High Temp and Other Ferrous Material up to 50 HRc
Cutting Application
Slotting, Roughing, Profiling and Finishing
  • Ultimate design on variable helix geometry generates harmonics shift, resulting in minimal chatter, exceptional finish and longer tool life
  • Eccentric Relief on the cutting edge has full support permitting higher feed rates and progressive wear is countered by increased flute thickness
  • High performance chatter free machining provides versatility in use for all ferrous materials
  • Enables higher SFM and heavier chip loads than conventional carbide end mill
  • ALCRO-MAX coating has remarkable wear resistance at lower feeds and speeds and under high mechanical loads, and can be used for roughing and finishing operation. Because of its titanium addition, surface finish of the work piece (Ra, Rz) remains consistent and low during the life of the tool. ALCRO-Max particularly excels when machining under wet or MQL (minimum quantity lubrication) conditions, cold and hot working steel, hardened and tempered up to 54 HRc
  • Cutting diameter tolerance: +.000, -.002"
  • Shank diameter tolerance: -.0001, -.0004"
  • 100% Made in USA
