Drilax Diamond Drill Bits for Stone and Glass – 30 Pc Set (1mm, 2mm, 3mm) 1/8 Shank for Dremel & Rotary Tools – Jewelry Making, Gemstone, Sea Glass and Lapidary Drill Bits Kit

I’m very happy with this DRILAX diamond drill bit set. The case arrived well-packaged, and the bits were neatly organized and clearly labeled by size (1mm, 2mm, and 3mm). The diamond coating looks even and well-applied, with no visible defects. I used these on glass and ceramic, following the instructions to start at an angle and use water, and they performed exactly as expected. The bits cut cleanly without chipping, and none of them overheated or lost their grit during use. For small, precise holes, they work extremely well. For the price, getting 30 pieces is a great value, especially if you do detailed or repetitive work like crafts, tile, jewelry, or DIY projects. The storage case is also a nice bonus for keeping everything organized. Just be sure to use water and take your time—these bits do a great job when used properly. I would definitely buy this set again and recommend it to anyone needing small diamond drill bits

I’m really happy with the Drilax Diamond Drill Bits set. The variety of sizes is perfect, especially for detailed work, and everything arrived exactly as described. I used them on glass and small stones, and they cut cleanly without chipping when used with light pressure. The bits feel solid and well made, not flimsy or disposable like some other sets I’ve tried. They’re also very easy to use, even if you’re newer to jewelry making or lapidary work. The 1/8 inch shank fits my Dremel perfectly, and the bits stay secure while drilling. With a little water for cooling, they perform smoothly and consistently. Overall, this is a reliable, well thought out set that works exactly as described and is a great addition to any jewelry making or craft setup.

Very nicely works well

The diamond drill bits are amazing. They cut stone and rocks so easily and they dont break. I love the variety of sizes as well. I liked this kit so much im going to buy a second for my daughter so we can work together!

Great set for drilling stone! Three sizes. Very sharp! Very good price also.

I bought these specifically to drill a small hole in a piece of rock to make a necklace for child’s birthday present. I used a drill press and continued to wet the stone. Within seconds the bit started melting at the tip even with water and got so hot it bent. I tried a second bit and applied water almost constantly and drilled very slowly. The bit was barely scratching the rock but again even with water it started melting off the tip and eventually broke off inside the small rock which also broke when I tried to remove it. Third bit on the same rock I submersed the stone in water and went very slowly in and out and it worked. Maybe these work for glass but definitely not recommended for hard gem stones like agate and jasper unless you submerse it, go very slowly and clear out the hole repeatedly.

These drills are great. Drill perfect holes thru my tumbled stones so I can make jewelry. They came in three sizes all perfect fit for my needs and the quality was better than expected along with the price. Have done over a dozen still using one drill as none dulled or broke. Very sharp. Will buy again

These work well for the money but water to keep em cool makes them last a lot longer.
