4Mm X 16Mm X 4Mm X 75Mm Altin Coated Carbide 4 Flutes Square End Mill Cutter

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. 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. 35 degree spiral chip space design for fast and clean chip removal. The cnc end mill is suitable for alloy steel, stainless steel, carbon steel, pre-hardened steel, hardened steel, cast iron, non-ferrous metals, and plastics (cutting hardness below HRC55 materials). 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. Works with CNC machining centers, engraving machines and other high-speed CNC machine tools. 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. Note: Use proper lubrication and cooling methods when machining. Using coolant or a suitable cutting fluid can help dissipate heat and improve chip evacuation. Select the appropriate square end mill based on the specific machining requirements, material type, and cutting conditions.
