【Material】: Cnc 4 Flute Solid Carbide Spiral Router Bit excel at working carbon steels, alloy steels, pre-hardened steels, hardened Steels, cast iron,etc.Strictly for steel use, if milling aluminium, our 3 flute end mill is recommended.

【AlTiN Coating】: Titanium aluminum nitride (AlTiN) coating lubricates the end mill for stability at high temperature and superior wear resistance at high cutting speeds, offering better heat resistance than TiAlN, TiN or TiCN coatings

【High Performance】: carbide has higher hardness and wear resistance and excellent cutting performance than high-speed steel.

General Usage: Applicable with copper, copper alloys, cast iron, steels, carbon steels, alloy steels, pre-hardened steels, hardened steels, and stainless steel materials. Best use for materials HRC less than 50.

Solide Carbide: The material is European origin ultra fine grain carbide. We use the highest quality tungsten carbide powders and adjust the ratio of tungsten carbide and cobalt to meet the ideal hardness. It is stable and has excellent wear-resistance of the material. It significantly enhances the tool's lifespan and keeps the end mill sharp. It also helps keep the surface quality of your work-piece at the best level possible.

AlTiN Coating: It is a strong coating that's coated at temperatures between 450°C to 475°C. It is able to provide high wear resistance, lubricity, exceptional oxidation resistance, extreme hardness, and excellent abrasive wear resistance. It has higher reliability in dry operations, heat resistance, hard machining, and the resistance can be reduced.

DLC coating (diamond-like coating)-The tool surface to obtain ultra-high hardness(HV7000) Low coefficient of friction(μ=0.08-0.15)，Strong adhesion resistance

Use ultrafine grain tungsten steel matrix，Perfect combination of toughness and hardness，Improve wear resistance while avoiding breakage and fracture

Manufactured with five-axis precision grinding machine, Each milling cutter is tested by tool testing instruments，Good stability of dimensional accuracy
