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

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

I am restoring some old jigsaw puzzles, and these are PERFECT for milling the edges of repairs. They are just the right grit to leave no marks, and fit perfectly into the high-speed tool I am using.

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.

I primarily bought the set for the 2.35 mm shanks to fit quick change handle I havent found a set of diamond bits that survives my abuse for very long so they seem to be equal to other sets

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.

Best deal and Quality

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

Excellent quality and service

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

Inexpensive and do the job for cutting, but they rust fast. Make sure you keep them dry.
