Designed for precision cutting with diameters ranging from 0.8 to 3mm and a 1/8" shank, this 10-piece set delivers smooth, chip-resistant performance ideal for detailed CNC projects. Trusted by thousands, these bits extend tool life and maintain finish quality under high-speed conditions. ## Description SPECIFICATIONS Shank Diameter: 3.175mm Cutting Edge Length: 12mm Overall Length: 37mm Cutting Edge Diameter: 0.8-3.0mm; 10Pcs; Innovative Nano Blue Coat Chemical Composition: Ni-La203 Physical Characteristics: 1. Enhance the hardness of the bits. 2. Reduce the frictional resistance coefficient of the bits at high speed to improve the smoothness of the machined surface. 3. Increase the heat dissipation performance of the bits to avoid the influence of the crystal structure change due to excessive temperature. 4. Reduce the phenomenon of chipping of the cutting edge. Enhance the elasticity of the bits. The impurities of the workpiece can be elastically skipped to avoid damage to the cutting edge. 5. Extend service life. 6. Since the carbide bit has high hardness and is relatively brittle, the machine speed range should be controlled during use.

To engrave I would set the passing depth at 0.5mm and the feed rate between 150 and 300 mm/min, spindle speed between 300 and 500 rpm. Aim a cooling fan at the work piece and keep a vacuum handy. **Q: Can It engrave on copper?** A: It's possible, but I wouldn't recommend it. Engraving on metal, even one as soft as copper, would dull the bits quickly. **Q: Why is amazon shipping from Baltimore to Kentucky and back to baltimore?** A: All 2 day air packages go to the hub in Kentucky first. You could ship something 2 day air to your next door neighbor and it will go to Kentucky first. Crazy, right? **Q: Are these upcut or downcut? Can this vital piece of information be added to your product specs please?** A: I believe they are Burrs and neither upcut or downcut however, they have an appearance of being upcut. Although I have them, I have not used them yet. ## Frequently Bought Together - SainSmart Genmitsu 10Pcs Nano Blue Coat End Mill CNC Router Bits, 0.8-3mm, 1/8" Shank - Genmitsu 10 Pcs 1/8" Shank V-Groove CNC Router Bits, 10 /15 /20 /25 /30 /40 /45 /60 /90 Degree Set, Nano Blue Coat Conical V-Bit, Engraving Tool for CNC Signmaking Carving Lettering 2D&3D Sculpture - Genmitsu 30pcs PCB Drill Bits Set, 0.1mm-3.0mm, 1/8" Shank Spiral Flute CNC Router Bits for Print Circuit Board Jewelry CNC Engraving, PD30A --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/253890371-sainsmart-genmitsu-10pcs-nano-blue-coat-end-mill-cnc-router](https://www.desertcart.jp/products/253890371-sainsmart-genmitsu-10pcs-nano-blue-coat-end-mill-cnc-router) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-18*
