5Pcs Carbide Square End Mill 1/4" Altin BN Coated 4 Flutes Bit 2-1/2" Long

Cutting Diameter: 1/4" Shank Diameter: 1/4" Cutting Length: 3/4" Total Length: 2-1/2" Material: Tungsten Carbide (Solid Carbide) Finish: AlTiN BN Coated Number of Flutes: 4 End Cut Type: Square End Cutting Direction: Upcut (Right Hand) Package Included: 1pcs x Carbide Square Nose End Mill Descriptions: Square end mill can create slots (keyways or internal grooves), straight or square edge features, flat smooth surfaces, holes or for roughing, finishing and side milling operations. Suitable for machining hardened materials, cast iron, high-temperature alloys, aluminum, and non-ferrous metals. Micro grain carbide mill bits offer high hardness, wear resistance, enhanced rigidity and excellent heat resistance. Aluminum Titanium Boron Nitride coating combines the advantages of both AlTiN and BN coatings. Offers superior thermal stability, reduced friction, and improved wear resistance compared to AlTiN. Features precision ground cutting edges for clean, precise cuts, resulting in accurate machining and excellent surface finish on your workpiece. Up-cut spiral flutes lift chips upward and away from the cutting area, providing excellent chip evacuation. Large spiral design helps effectively remove chips during cutting, reducing clogging and improving chip evacuation. Universal chamfered round shank, good compatibility and easy to use. Use on standard milling machines, CNC machining centers, engraving machines and other high-speed CNC machine tools. The longer the length of the tool clamped by the chuck, the better.
