Download location of the database Please refer to the Product Guide and Documents on the product page. We have included the download links for the various software, including Fusion 360, Carveco and G-Wizard, in a PDF document (can only be called a USER GUIDE due to desertcart policy). To cover all the other options, we have included two tables with all the parameters for bits, speeds and feeds. What's it for? The Tool Database is used to make tool management and selection very quick and easy, reducing the possibility of programming jobs with incorrect depths, speeds and feeds. The Tool Database is accessed from the Select button each time a new toolpath is created and allows pre-defined tools and settings (speeds, feeds, etc.) to be selected from a list. Overall, a tool database can help you save time, money and improve safety in your workplace. Note: The database can only be used as a guide, please start with conservative settings, low speeds and depths of cut and see what speeds and feeds work best for your specific application.

Review: Great little corn cobs - The 1/8 cob cut bits are monsters, Love 'em, wish I could buy them in a stand alone pack. I just sit like a cave man and watch them granulate steel. I've always thought that chips were the way to go but these little guys showed my something different. I thought that these were more for wood and such and only grabbed it off my shelf out of desperation but they cut well. I had to feed it a slow cutting speed (.001 or so per sec at 900 rpm) but it worked like a charm on 1045. I chewed one up after about an hour, but I had gotten a little impatient and dinged the very tip up. The flutes kept cutting! The price on these is good, like I said, just wish I could buy the 3mm in multi packs by themselves. Review: Affordable and effective - So far these have worked great for cutting wood. Just be sure to get your feeds and speeds right. Run them too fast and you break them, run them too slow and you create friction which heats them up until the either break our wear out very fast. Even the most expensive endmills in the world can be destroyed by operator error. I got good results cutting hardwood with the 1.4mm bit using SFM: 141, chipload of .005, and a depth of cut of .0157 (4mm). I would not probably not recommend cutting metal with these, but I have not tried it yet. ## 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 | #63,598 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #4 in Drill Mills #82 in Spiral Router Bits | | Brand Name | SainSmart | | Customer Reviews | 4.4 out of 5 stars 3,405 Reviews | | Cut Type | Plain End | | Cutting Diameter | 3 Millimeters | | Cutting Length | 12 Millimeters | | End Cut Type | Center | | Finish Type | Nano Blue Coat | | Finish Types | Nano Blue Coat | | Global Trade Identification Number | 04897093841353 | | Helix Angle | 3E+1 Degrees | | Item Dimensions L x W | 1.46"L x 0.13"W | | Item Weight | 0.01 Ounces | | Manufacturer | SainSmart | | Material | Carbide | | Material Type | Carbide | | Model | 70C08 | | Number of Cutting Edges | 2 | | Number of Flutes | 2 | | Part Number | 101-60-70C08 | | Shape | Round | | Size | 0.8-3mm | | Size Name | 0.8-3mm | | Tolerance Held | Precision | ## Product Details - **Cutting Diameter:** 3 Millimeters - **Cutting Length:** 12 Millimeters - **Finish Type:** Nano Blue Coat - **Material:** Carbide - **Number of Flutes:** 2 ## Images ![C08 - Image 1](https://m.media-amazon.com/images/I/71YsFa2AGSL.jpg) ![C08 - Image 2](https://m.media-amazon.com/images/I/81X-sygyPDL.jpg) ![C08 - Image 3](https://m.media-amazon.com/images/I/715w7hH+FML.jpg) ![C08 - Image 4](https://m.media-amazon.com/images/I/71-6tUx2jSL.jpg) ![C08 - Image 5](https://m.media-amazon.com/images/I/61hClO7pE5L.jpg) ## Available Options This product comes in different **Size** options. ## 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 ### ⭐⭐⭐⭐⭐ Great little corn cobs *by R***. on February 18, 2026* The 1/8 cob cut bits are monsters, Love 'em, wish I could buy them in a stand alone pack.

I would not probably not recommend cutting metal with these, but I have not tried it yet. ### ⭐⭐⭐⭐ Actual dimensions are all over the place. *by J***C on September 9, 2022* The largest is in fact very close to 3.175mm, and the smallest close to 1.5mm, but other than that they seem to be placed at random sizes, nowhere close to representing the dimensions shown in the photo. I also got two identical 2.4mm bits, which is not a huge deal for me, but I was consider using the 2.2mm for something and I didn't get one. So they're cheap and good for things that don't require a specific width dimension. ## 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? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/122696645-c08](https://www.desertcart.in/products/122696645-c08) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-21*
