Yakamoz 30Pcs 2.35mm Shank Titanium-Coated Diamond Burrs Set Rotary File Burs Accessories Kit for Rotary Grinder Tools Grinding Polishing Carving Stone Jewelry Glass Ceramics

Best deal and Quality

They cut very good (hardwood), and are durable. Enough said.

Bueno

They will work for what I do, but not the best cut from them

How beautifully it works when cleaning my jewelry in the fabrication stage. They clean ever tiny space that I cannot reach with regular tint hand files. A very nice product, perfect shakes and sizes.

These are a nice array of bits for the price, but its worth passing along that some of the tips are slightly off, compared to the product image on amazon. I would imagine that wouldnt be a problem for most, but just in case you need a precise mirror of what youre seeing. For instance, the tear-drop tips are probably the most different from the product imagery.

After using them for the first time the next day they were covered in rust Very disappointing Ive never had any of my bits rust that fast

They last between five and ten seconds before melting no matter the speed on the dremel

Excellent quality and service

These are the longest lasting diamond burrs that I have used in over 20 years of carving stone.
