Wide Applications Suitable for PCB, SMT, CNC, MDF, ABS, PVC, mold, acrylic, nylon, resin, plastic fiber, carbon fiber, MDF boards, hardwood, plywood, printed circuit boards and other precision parts that are machined and milled. Premium Quality With sufficient flexural strength and wear resistance to ensure high working efficiency. Sharp cutting edge, milling, hole and plate edge, clean surface, neat, no defects. Cost-Effective With 10 pieces per set, the set is very inexpensive for CNC manufacturers. It comes with a portable plastic container, and each is kept in its own box, so the bits are easy to store and transport. Why choose the Genmitsu Nano Blue Coat CNC Router Set? Enhance the hardness of the bits. Reduce the frictional resistance coefficient of the bits at high speed to improve the smoothness of the machined surface. Increase the heat dissipation performance of the bits to avoid the influence of the crystal structure change due to excessive temperature. 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. Extend service life. Review: Work well in Dremels - I don’t have a CNC! So I can’t comment on their performance for this, but these work well in my Dremel, nice and sharp good for detailing at a slower speed or clearing waste on my wood carving projects. The smaller ones are easy to break, however this could be because I’m using them differently. Review: Good product - Work great. Reasonable price ## Features - Cutting Edge Diameter: 0.8 - 3.0mm (0.8/1.0/1.2/1.4/1.6/1.8/2.0/2.2/2.4/3.0mm), 10Pcs. - Hard Steel: With sufficient flexural strength and wear resistance, which ensure high work efficiency. - Material: Using ultra-fine grained carbide material, with good milling and cutting performance. - Advantage: Sharp cutting edge, milling, hole and plate edge, clean surface, neat, no glitches. - Application: PCB, SMT, CNC, Mold, plastic fiber, carbon fiber, hard wood, printed circuit board, and other precision parts processing. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07P7LGQJ6 | | Best Sellers Rank | 13,688 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 3 in Drill End Mills | | Brand | SainSmart | | Country Of Origin | China | | Customer Reviews | 4.5 out of 5 stars 3,368 Reviews | | Cut Type | Plain End | | Cutting Diameter | 0.8 Millimetres | | Cutting Length | 12 Millimetres | | Cutting diameter | 0.8 Millimetres | | Cutting length | 12 Millimetres | | End Cut Type | Center | | Finish Types | Nano Blue Coat | | Finish type | Nano Blue Coat | | Global Trade Identification Number | 04897093841353 | | Helix Angle | 3E+1 Degrees | | Item Shape | Round | | Item Weight | 0.01 Ounces | | Manufacturer | SainSmart | | Manufacturer Part Number | 101-60-70C08 | | Material | Carbide | | Model Number | 70C08 | | Number of Cutting Edges | 2 | | Number of Flutes | 2 | | Number of flutes | 2 | | Size | 0.8-3.0mm | | Size Name | 0.8-3.0mm | | Tolerance Held | Precision | ## Product Details - **Cutting diameter:** 0.8 Millimetres - **Cutting length:** 12 Millimetres - **Finish type:** Nano Blue Coat - **Material:** Carbide - **Number of flutes:** 2 ## Images ![SainSmart Genmitsu 10Pcs Nano Blue Coat End Mill CNC Router Bits, 0.8-3mm, 1/8" Shank - Image 1](https://m.media-amazon.com/images/I/71YsFa2AGSL.jpg) ![SainSmart Genmitsu 10Pcs Nano Blue Coat End Mill CNC Router Bits, 0.8-3mm, 1/8" Shank - Image 2](https://m.media-amazon.com/images/I/81X-sygyPDL.jpg) ![SainSmart Genmitsu 10Pcs Nano Blue Coat End Mill CNC Router Bits, 0.8-3mm, 1/8" Shank - Image 3](https://m.media-amazon.com/images/I/715w7hH+FML.jpg) ![SainSmart Genmitsu 10Pcs Nano Blue Coat End Mill CNC Router Bits, 0.8-3mm, 1/8" Shank - Image 4](https://m.media-amazon.com/images/I/71-6tUx2jSL.jpg) ![SainSmart Genmitsu 10Pcs Nano Blue Coat End Mill CNC Router Bits, 0.8-3mm, 1/8" Shank - Image 5](https://m.media-amazon.com/images/I/61hClO7pE5L.jpg) ## Questions & Answers **Q: will these cut aluminum?** A: The machine can engrave aluminum as far as cutting it it would take a very long time depending on the hardness. 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Work well in Dremels *by R***M on 23 October 2025* I don’t have a CNC!
