Review: Worked great for shark teeth - I needed to drill holes in some shark teeth...like most normal folks do on a daily basis, of course. In particular, I wanted small holes just large enough for wax thread. So, I found these bits and thought I'd give them a shot. I had no illusions that these would be heavy duty for the price and just hoped that a set of thirty bits would be enough to drill 14 holes. Well, I have to say that I'm impressed. Not only did they work...But, I drilled all 14 holes in fossil shark teeth using just one bit. So, after reading all the other reviews, this was far better performance than I'd expected. Here's how I did it. 1. I found a small round tin with 2" high walls to use to hold the water and base for drilling. 2. I packed some Plasticine modeling clay into the bottom to act as a grip to hold the tooth. 3. I embedded the tooth into the clay and put enough water to cover the tooth by about a half inch. 4. I put the bit in my Dremel and set it to one of the lowest speeds. This is important because I think a lot of people are running these too fast and burning the grit off. 5. I slowly drilled into the tooth and frequently backed out to allow the filings to wash out of the hole and to cool the bit. I think it took less than an hour to drill 14 holes through shark teeth around 1/8 to 3/16" thick. That is the pro...definitely worth the money. The downside - Don't expect all the bits to be drill worthy. I mean, if you are drilling any sort of precision holes, only half of the bit tips are true enough for accuracy. The rest are fine for grinding edges or maybe enlarging holes. Some are slightly bent and some are varying diameters...just not precision manufacture. So, don't expect anything amazing for ten bucks. But, I'd definitely recommend them. Review: Very Pleased - I'm very pleased with these diamond bits. They have worked perfectly for me opening up and grinding holes in glass. They seemed at first to be too thin and fragile for what I was doing but so far are holding up well! ## Features - Set of 30 pcs. 1mm Diamond Drill Bits - 1/8 shank - Fits drills, flex shafts and dremels. - Used by Jewelry Designers for drilling clean holes - Drills Beach Sea Glass, Sea Shells, Rocks, Marbles, etc. - For Making Earrings, Pendents and Bracelets. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07L86Y83S | | Best Sellers Rank | #443,018 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #464 in Power Rotary Tools | | Brand | Oudtinx | | Brand Name | Oudtinx | | Customer Reviews | 4.1 out of 5 stars 1,615 Reviews | | Cutting Angle String | 135 Degrees | | Cutting Diameter | 1 Millimeters | | Finish Type | Diamond | | Finish Types | Diamond | | Manufacturer | Oudtinx | | Material | alloy | | Material Type | alloy | | Minimum Bore Diameter | 1 Millimeters | | Number of Flutes | 1 | | Number of Pieces | 30 | | Set Name | Oudtinx 30-Piece Diamond Drill Bit Set | | Shank Type | Straight | | Surface Recommendation | Glass | | Tool Flute Type | Straight | | UPC | 656664572003 | | Unit Count | 30.0 Count | ## Product Details - **Brand:** Oudtinx - **Cutting Diameter:** 1 Millimeters - **Finish Type:** Diamond - **Material:** alloy - **Shank Type:** Straight ## Images ![30 Pack 1mm Diamond Drill Bit for Dremel Craftsman Rotary Tool 1/8" Shanks Jewelry Beach Sea Glass Shells Gemstones Lapidary 30pcs. - Image 1](https://m.media-amazon.com/images/I/61L0uufvtlL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Can i drill small holes in a glass jar with these?** A: These diamond bits arent made to drill on glass they are used to etch on glass. To drill holes on glass you need a carbide bit and make sure you constantly keep the bit wet by spraying with water or anti freeze while you drill so you dont damage the bit and also so that the glass doesnt get too hot and end up breaking **Q: can these drill bits be used to put a hole in gemstone or are they just used for etching?** A: I use the 1&2 mm to drill my stones. I also purchased 30 box of all 1 mm,for drilling... **Q: Can I cut slots in in weld epoxy with these ?** A: I do not expect this drill to cut from its sidewall for hard material. For softer material, it could work. **Q: Is there a burr cup in here? to smooth and clean ends of wire** A: No ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked great for shark teeth *by M***R on April 12, 2021* I needed to drill holes in some shark teeth...like most normal folks do on a daily basis, of course.

They have worked perfectly for me opening up and grinding holes in glass. They seemed at first to be too thin and fragile for what I was doing but so far are holding up well! ### ⭐⭐⭐⭐ Good, but predictably flimsy *by E***A on November 28, 2023* I got these to sand paint out of some very small corners, and they did the job. The only caveat is that the extremely thin metal warps a bit when when dremel gets going, and the tip makes a circle around an axis instead of spinning right on the axis. Once the tip was on the metal, i could press it into staying in place, but because of the extra pressure i also got a couple of unwanted grooves. Once I had a feel for how they needed to be handled though, they were wonderful for fine detail work. --- ## 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.com.ar/products/112927445-30-pack-1mm-diamond-drill-bit-for-dremel-craftsman-rotary](https://www.desertcart.com.ar/products/112927445-30-pack-1mm-diamond-drill-bit-for-dremel-craftsman-rotary) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-07-06*
