12X3Mm Tungsten Carbide Cnc End Mill Cnc Router Bits Left Hand 2Pcs

Attributes:* Cutting Edge Diameter: 3mm / 0.118"* Shank Diameter: 3.175mm / 1/8"* Cutting Edge Length: 12mm / 0.472"* Overall Length: 38mm / 1-1/2"* Milling Direction: Left Hand* Material: G05 Tungsten Carbide* Finish: Diamond Film Coated* Coating Process: CVD (Chemical Vapor Deposition)* Style: Corn ShapeWhat Is Included:* 2 Pieces x End Mill Router BitsApplications & Features:--- Widely used for drilling PCB (print circuit board), acrylic, plastics, aluminum, soft metal, fiberglass, wood, etc. Suitable for PCB drilling machines, engraving machines, CNC and high-precision special drilling equipment. Use vertically and control your CNC speed well. Can work quickly and cleanly, no glitches or scrap left.--- Sharp cutting edge provides smooth drilling, low cutting force and drilling accuracy to prevent tool breakage. Large chip removal space, smooth chip removal, and low drilling heat. The positioning ring reduces machine set-up time and increases efficiency.--- Tungsten carbide bits have high hardness, good toughness, wear resistance, high strength, resistance to bending and heat resistance, providing a precise and easy experience. --- The diamond film coating processed by CVD (Chemical Vapor Deposition) is very close to natural diamond and has high hardness, high elastic modulus, high thermal conductivity, good self-lubrication and chemical stability.Useful Tips:--- The mini drill bit is too tiny and easily twisted off. Be careful and control your CNC speed. The longer the chuck clamps, the better. If the clamping length is short, the feed rate and cutting speed should be reduced to reduce vibration and increase tool life.
