Product Series:XY-650 Product name: 65 degree blue nano milling cutter Specifications: 1-20MM Blade: flat knife with four edges Granularity: 0.03 Helix angle: 45 Packing quantity: 1PC Applicable models: CNC, machining center, engraving machine, high-speed machine, etc. Applicable materials: tool steel, stainless steel, hardened steel, carburized steel, alloy steel, titanium alloy, pre-hardened steel, cast iron and cast steel Kind tips: 1. Appropriately reducing the cutting speed and feed speed can extend the service life of the milling cutter. 2. Cutting fluid needs to be added during work to protect the blade and make cutting smoother. 3. The shorter the length of the tool protruding from the chuck, the better. If it protrudes longer, please reduce the rotation speed or feed speed by yourself. Select high-quality tungsten steel base material. Extremely wear-resistant and lasts 2.5 times longer than uncoated tools. Made with high quality machine tools. It can perform finishing and semi-finishing on materials heat-treated below 65 degrees Celsius. The unique spiral edge angle effectively solves the problem of tool sticking, enhances tool hardness and tool service life, and reduces the number of tool changes. The unique handle end chamfer design is easy to install, and it is closer to the chuck for tighter grip without slipping. At the same time, the stability of milling is increased, and the fine polishing accuracy of the tool holder body is controlled within 5M. The knife edge is double-layer passivated. The double-layer passivation before and after the knife edge coating is carefully ground to make the tool edge burr-free milling smoother and extend the service life of the tool.
