Specification:Cutting Edge Diameter: 1.5mm / 0.059"Shank Diameter: 3.175mm / 1/8"Cutting Edge Length: 8.5mm / 0.33"Overall Length: 38mm / 1.5"Material: Cemented CarbideSurface Treatment: Titanium CoatedPackage Content: 10 x Carbide End Mill Engraving Bits Description:1. Made from carbide material, good milling properties to ensure efficient work.2. Great replacements for your CNC or PCB machinery. With sufficient flexural strength and wear resistance.3. Sharp cutting edge, milling, hole and plate edge, surface clean, neat, no glitches.4. Wide ranges of materials can be engraved, including: circuit boards, metal, plastics, wood, SMT, PCB, fiber glass, carbon, etc..5. Tips: The longer the length of the tool clamped by the chuck, the better. If the clamping length is shorter, you need to lower the feed rate and cutting speed to reduce vibration and extend the tool life. 6. Combined with the material to be processed, select an appropriate feed rate and cutting speed to improve the tool life and obtain better processing accuracy and performance.
