Stone Carving Set Diamond Burr Bits Compatible with Dremel, 50PCS Polishing Kits Rotary Tools Accessories with 1/8’ Shank For Carving, Engraving, Grinding, Stone, Rocks, Jewelry, Glass, Ceramics

This was perfect for stone repair. Slightly opening up fissures and pinholes to provide space for adhesive. The super small/thin straight bar bits suck but the cones are excellent as well as the discs

I bought this drill bit set as a gift, and it completely exceeded my expectations. The quality of the materials is excellent: you can tell they're built to last. They come well organized in a sturdy case, which makes storage and transportation very easy. Furthermore, the performance on various types of surfaces has been impeccable: wood, metal, and even plastic. It's clear this is a product designed for those with experience and looking for professional-grade tools. Highly recommended for those who value precision and durability.

I bought these to carve porcelain tiles for my backsplash. It made it easy for me to cut the crazy shapes that fit under the cabinets. As a former bench jeweler, I was able to use them in my flex shaft. Much more efficient use of my time when I have the correct tools! So glad that I ordered these. Prior - I was breaking tiles left and right, trying to cut and snap pieces out. Now my project is moving along nicely!

If you don’t use water, they don’t last long when cutting rocks (specifically chalcedony - Ellensburg blue). But for the price, not too bad.

The big set worked really well and were decently long lasting. The small ones didn’t work or have enough grit in them. So it was effectively half of what I wanted. I use these to carve into different stone materials, some are harder than others. Probably wont purchase again.

Love this set of detail burrs. I love to carve duck decoys and little Santa heads. This set of sanding burrs helps me get the fine detail I look for in my work. Fits my Dremel perfectly. Love these and recommend for your Dremel detail work also!!

They work great for etching and engraving. Value for money. Fits in my other two engravers as well.

Ive used these on numerous different materials and was never disappointed. Even after heavy prolonged use i dont see any of the diamond plating rubbing off. If possible, use water or some kind of lubricant to keep everything clean and to prevent clogging.

Mala calidad por el precio. Creo que lo venden más por el peso del metal que la propia calidad. No lo recomiendo, hay mejores productos por el mismo precio
