20Pcs 0.5Mm End Mill Bit 1/8" Shank Carbide CNC Router Bit Engraving Cutter Tool

This milling cutter is made of tungsten steel (carbide), which has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. These properties extend tool life and keep end mills' edge, helping to improve cutting accuracy and efficiency. Corn-shaped cutting edge, diamond-shaped cutting teeth, fishtail-shaped cutting tip, CNC router bits integrating drilling and milling. This manufacturing process effectively reduces cutting resistance, minimizes vibration during processing and reducing errors caused by tool vibrations, ensuring a smoother cutting process without damage. This flat end mill is frequently used in PCB circuit boards, various CNC milling machines, woodworking CNC tools, and engraving machine tools. In addition, it is also suitable for cast iron, copper, carbon steel, alloy steel, pre-hardened steel, and hardened steel—processing of metal materials. Most end mills are clamped using spring clamps, to prevent the end mill from gradually protruding from the tool holder or even falling completely, we recommend that the end mill handle and tool holder be removed before clamping the end mill, clean the inner hole with cleaning fluid and dry it before clamping. Since there is a small gap between the end mill and the tool holder, if the tool vibrates during processing, please consider reducing the cutting speed and feed speed, and take measures such as adjusting the cutting amount, increasing the stiffness of the tool system, increasing the feed speed, etc. measure.
