(1) Appropriately reducing the cutting speed and feed can prolong the service life of the milling cutter. (2) When working, it is necessary to add cutting fluid to protect the cutting edge and make the cutting smoother. (3) When oxide film or other hardened layer remains on the surface of the workpiece, it can be removed by up-milling. (1) 55°4 flute coated end mill, sharp and strong, fast milling speed. (2) Cutting edge, TiSiN coated, TiSiN coating can directly rough to finish heat-treated materials up to 55°, reducing the number of tool changes, improving machine tool utilisation and saving manufacturing time. (3) 0.6um micro-grain carbide, micro-grain tungsten steel base material, with higher wear resistance and strength, belongs to the special milling cutter for high hardness high-speed cutting applications. (4) Fully sharpened cutting edge, sharp cutting, wear-resistant and durable, providing a strong guarantee to extend the service life of the milling cutter. What are the benefits of adding coating. 1? Higher wear resistance and sharpness of end milling cutter. 2? Reduce the number of tool change, save time, improve the use of efficiency. 3? Corresponding degree of heat treatment materials can be roughing to fine machining directly. (1) Due to the lighting effect and shooting angle and other reasons, the product has a colour difference, please understand. (2) Due to manual measurement, there are errors in product size. (3) You can find more products with different materials, types, colours, sizes, quantities and shapes in our shop. (4) If you have a big demand, you can find us a discount!
