BestParts HRC65 Tungsten Carbide Square End Mills - TiAlsiN Nano Coated, 4 Flute, 45 Degree Helix, 3 /8 inch Cutting Diameter, 3 /8 inch Shank Diameter, 1 inch Length of Cut, 2-1 /2 inch Overall Length

Features

• Size: 3/8" cutting diameter x 3/8" shank diameter x 1" length of cut x 2-1/2" overall length, 4 Flute, 45 Helix, Solid Carbide End Mill, TiAlsiN Nano Coated.
• Coated: TiAlsiN Nano Coating can improve the oxidation resistance,high temperature resistance and wear resistance of the workpiece. The hardness of the coating can reach 4500HV, and it has strong wear resistance.it's service life is five to six times longer than other coated tools.
• Material: Solid carbide tools offer long tool life and faster cutting speeds than other substrates, Carbide can run at higher speeds than high-speed or cobalt steel, resisting wear and high cutting temperatures.
• Features: Precision ground using the highest quality grinding wheels. High strength and hardness, abrasion resistant, practical, easy to use and durable in use.
• Application: Used for finishing machining of high-hard materials of hardness HRC60 such as Alloy Steel, Hardened Steel, Iron, Copper, and nonferrous materials.
