Key features

• Size: 5/16" Cutting Diameter, 5/16" Shank Diameter, 13/16" Length of Cut, 2-1/2" Overall Length, 5PCS
• AlTiN Coating: The aluminum titanium nitride coating offers resistance to high-temperature oxidation and limits material adherence to the flute surface during use.
• 4-Flute Geometry: The four-flute configuration features a greater core thickness than designs with fewer flutes, resulting in higher rigidity and permitting higher feed rates.
• HRC45 Hardened Carbide Body: Suitable for Machining Stainless Steel, Cast Iron, Tool Steel, High Alloy Steel. Ideal for 3D contouring, arc grooves, and mold machining.
• Mirror Finish: The flutes are highly polished to reduce friction and ensure smooth chip flow, preventing material adhesion during high-speed cutting.
