Features: This milling cutter is made of tungsten steel with good milling, cutting performance, ensuring high work efficiency. Sufficient anti-bending strength, high hardness, high wear resistance and high strength. Smooth and tidy groove to avoid sticking knife, greatly improve efficiency. The cutting edge adopts an internal arc design to reduce the wear in cutting and make the cutting head more incisive and durable. Chamfering design enhances the seismic resistance of the milling cutter, convenient to use. Specification: Material: Tungsten Steel Compatible models: manual milling machine, CNC milling machine Application: carbon steel, iron, copper, aluminum alloy, insulation board, wood, bakelite, PVC board Model (Optional) HeadDiameter BladeLength Shank Diameter Overall Length 4*17 3mm / 1.2in 18mm / 7.1in 45mm / 17.7in 45mm / 17.7in 4*22 3mm / 1.2in 23mm / 9.1in 45mm / 17.7in 45mm / 17.7in 4*25 3mm / 1.2in 25mm / 9.8in 45mm / 17.7in 45mm / 17.7in 4*28 3mm / 1.2in 28mm / 11in 50mm / 19.7in 50mm / 19.7in Package List: 1 x Milling Cutter Note: 1. Proper reduction of cutting speed and inlet speed can extend the service life of the milling cutter. 2. Need to add cutting fluid to protect the cutting edge, cutting more smoothly. 3. When workpiece surface residual oxide film or other hardened layer, can be removal by reversible milling. 1、This milling cutter is made of tungsten steel with good milling, cutting performance, ensuring high work efficiency. 2、Sufficient anti-bending strength, high hardness, high wear resistance and high strength. 3、Smooth and tidy groove to avoid sticking knife, greatly improve efficiency. 4、The cutting edge adopts an internal arc design to reduce the wear in cutting and make the cutting head more incisive and durable. 5、Chamfering design enhances the seismic resistance of the milling cutter, convenient to use.
