HARFINGTON Square End Mill 3.5mm x 12mm Cutting 4mm Shank Micro Grain Solid Carbide AlTiN Coated 2 Flutes Milling Bit Cutter for Alloy Hardened Steel Aluminum

Features

• Size - Cutting diameter: 3.5mm / 0.14"; cutting flute length: 12mm / 0.47"; shank diameter: 4mm / 0.16"; overall length: 50mm / 2"; cutting hardness: HRC55; number of flutes: 2 flutes
• Material - Micro Grain Solid Carbide end mill cutter offers high hardness, wear resistance, and heat resistance. Carbide material with good milling and cutting performance, run at higher speed than high-speed steel.
• Feature - Square end cut, 2-flute design, spiral chip space design for fast and clean chip removal. Premium AlTiN (high aluminum & titanium) composite coating can increase hardness and wear resistance, and apply lubricant better for smoother milling and longer service life.
• Application - The milling bit is suitable for cutting alloy steel, stainless steel, carbon steel, cast iron, tool steel, hardened steel, great for shallow groove machining, side milling and finishing. Works with CNC machining centers, engraving machines etc.
• Note - The longer the length of the tool clamped by the chuck, the better. Select an appropriate feed rate and cutting speed to improve the tool life and obtain better processing accuracy and performance.
