HARFINGTON Square End Mills 1 /2 inch Cutting Dia HRC 60 4 Flutes AlTiN Coating Tungsten Steel Carbide Mill Bit for Hardened Steels

Features

• Package Content - Carbide Square End Mills, with a blade diameter of 1/2", blade length of 1.18"/30mm, total length of 1.97"/50mm, and a four-blade design. The shank is round and made of tungsten steel hard alloy material. This set is sold as a pack of 1 unit.
• AlTiN Coating - Titanium aluminum boron nitride (AlTiBN) coating that provides excellent heat resistance and wear resistance, making the end mills stable even when processing materials at high temperatures. This coating ensures longer tool life, improving efficiency and cost-effectiveness.
• HRC 60 High Hardness - The whole body of the end mill is made of tungsten carbide material, which has a high hardness and wear resistance, making it great for processing high hardness materials such as stainless steel, mold steel, hardened steels, or other materials lower than HRC 60 hardness.
• Quick and Clean Milling - 4 spiral flutes that provide efficient chip removal and prevent clogging, resulting in faster and cleaner milling, can produce a smooth finish on the workpiece. Suitable for side milling, end milling, slotting, step milling, CNC machining center, engraving machine and other high-speed machine tools.
• Note - Please ensure that the end mill is firmly clamped to the machine table before starting any machining operations.
