HARFINGTON Micro Grain Carbide Square End Mill 1/8" x 11/32" (3mm x 9mm) Cut 1/8" (3mm) Shank 2" (50mm) Length AlTiN Coated 4 Flutes Square Nose Cutter for Alloy Steel Hardened Steel - hta231225hh000347

• Size - Cutting diameter: 3mm / 1/8". cutting flute length: 9mm / 11/32". shank diameter: 3mm / 1/8". overall length: 50mm / 2". cutting hardness: HRC55. number of flutes: 4 flutes. end cut type: square end Material - Micro grain carbide end mills offer high hardness, wear resistance, enhanced rigidity and excellent heat resistance. Features sharp, precision ground cutting edges for clean, precise cuts, resulting in accurate machining and excellent surface finish on your workpiece. Features - AlTiN (aluminum titanium nitride) coating increases hardness and wear resistance, improves lubricity, enhances chip evacuation, and can withstand higher cutting speeds and feeds, providing better performance than TiAlN, TiN or TiCN coatings. Applications - Suitable for alloy steel, stainless steel, carbon steel, pre-hardened steel, hardened steel, cast iron, non-ferrous metals, and plastics. Square end mills are used to create slots (keyways or internal grooves), straight or square edge features, flat smooth surfaces, holes or for roughing, finishing and side milling operations. Note - Ensure that the square end mill is securely held in the tool holder or collet. Maintain stable cutting conditions by adjusting the feed rate and depth of cut appropriately. Use proper lubrication and cooling methods when machining.
