Revesun 10 Pcs Diamond Coated Cutting Wheels Discs 💎 Drill Bit Set for Dremel Rotary Tool - 40mm Stone Blade Review

I used this product to cut a gallon in half. I put the jug in the sink and poured some water on the blade to keep it warm while cutting with the Dremel tool. Took less than 10 min. Works great, only used one blade and is still in good condition. I highly recommend this product.

Excellent discs at a very solid price. You did the job and more. I would recommend them to anyone looking for diamond tipped blades that are inexpensive but work well provided you keep them cool and wet and don't overload them like other parts/parts of your tools and they last a long time. They while slightly more expensive for the same works.

Everything is fine, but none of the discs turns properly. I even took out my micrometer and measured each disc. The holes in the discs are off-center, so there's a lot of vibration and play. If you can handle the vibrations they cause when using them, they're fine for light grinding/sanding, but they don't cut for anything. Or at least not a good straight cut. Will NOT buy again!

Refund or exchange because I received a poor quality product. I used a pad of water to cool it down and the diamond was completely worn out in literally 2 minutes. The picture of an unused disc shows how rare the diamond coating on it is. I've ordered them before and after heavy use and grinned at the stones that have tarnished them, but none have worn down to bare metal like these. Disappointed as previous purchase was excellent.
