HARFINGTON 2pcs Square Nose End Mill 4mm Shank 1.5mm x 25mm AlTiSin Coated Solid Carbide Long Reach Extended Neck 4 Flutes CNC Router Bit Milling Cutter for Stainless Steel Hardened Steel

Features

• Size - Cutting diameter: 1.5mm / 0.06"; effective cutting length: 25mm / 0.98"; cutting edge length: 4.5mm / 0.18"; shank diameter: 4mm / 0.16"; overall length: 75mm / 3"; cutting hardness: HRC55; number of flutes: 4 flutes; end cut type: square end
• Material - Made of super fine grain carbide, the end mill cutter has high hardness (HRC92), high strength, and wear resistance. With good milling and cutting performance, carbide can run at higher speed than high-speed steel.
• Features - Square end cut, 4-flute design, large and spiral chip space design for fast and clean chip removal. Sharp cutting edge provides smooth cutting. The AlTiSin composite coating has high hardness, high wear resistance and high thermal stability.
• Applications - Suitable for cutting stainless steel, carbon steel, malleable cast iron, alloy steel, die steel, tool steel etc.. The end mill has an extended neck (long reach) that provides additional reach and clearance for machining deep or hard-to-reach areas.
• Note - Use on CNC machining centers, CNC machine tools, precision engraving machines and other equipment. 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.
