High Quality: The5PCS V-Groove CNC Router Bits are made of ultra-fine 0.2μm tungsten carbide steel alloy that can keep continuous machining 800 minutes. Nano Blue Coating: The hardness and heat resistance of the bits are enhanced with the Nano Blue Coating. It enables the tool's cutting edge to retain crucial sharpness and lubricity. This provides longevity and produces cutting results of the highest quality. Shank Diameter: 1/8” (3.175mm); Cutting Diameter: 3.175mm Cost Effective: The V shape bits are good at letting and sign making. This set of V-Groove CNC Router Bits includes 4 different degrees (20, 30, 45, 60), which is commonly used in 2D engraving and 3D sculpting. Wide Applications: Widely used to engrave on Acrylics, MDF, Plastics, Solid Woods, etc.
