This 8.00mm 4-flute solid carbide end mill features a square end, AlTiN coating, and a 55-degree high-helix cutting geometry. The 20mm length of cut provides useful reach for precision milling, profiling, finishing, light slotting, and flat-bottom pocketing in CNC applications.

The AlTiN coating helps improve wear resistance and heat resistance when cutting steels, stainless steels, and other harder materials. The 4-flute square-end design is well suited for finishing passes, contouring, and precision work where a clean flat-bottom cut is needed.

  • Tool type: Solid carbide end mill
  • Cutting diameter: 8.00mm / 0.3150"
  • Flutes: 4
  • End style: Square end
  • Coating: AlTiN-coated

Typical Applications

  • Precision CNC milling and profiling
  • Finishing passes in steels, stainless steels, and other harder materials
  • Light slotting and contouring
  • Flat-bottom pocketing and small-part machining
  • Model making, mold work, prototype work, and general CNC milling

Benefits

  • AlTiN coating helps improve heat and wear resistance in demanding materials.
  • 4-flute geometry provides a strong cutting edge layout for finishing and light milling operations.
  • 55° high-helix design supports smoother cutting action and improved finish quality in suitable applications.
  • 20mm LOC provides added cutting reach for deeper profiles and pockets.
  • 8mm shank matches the cutting diameter for simple toolholding in 8mm collets.
