30 Pcs Diamond Cutting Wheel Cut Off Discs Coated Rotary Tools W/Mandrel 22mm for Dremel by YEEZUGO

These are great, but I found they wear out fast if you force them through stone. I have cut several geodes with them and it cut easy and fast. Just don't put too much force. When cutting dry, take it slow and let the blade do most of the work. Using oil try to create a reservoir around the cutting area to keep blade cool and coated. Great product. The 50mm blades are even great at cutting and polishing using the edge.

Complete garbage. Saw attachment is down right dangerous. Arbor bent within 10 seconds of use and the saw blade tore my hand all up. Almost had a trip to the er....nothing a few feet of electrical tape couldn't fix.

I was using this for the first time in a rather simple project when the shaft bent and begun to spin wildly. Very dangerous. Luckily I hold my tool back a ways out this would have done some serious damage.

Absolutely what I needed. Thought of times past when I needed a good cut off disc. Went through a LOT of the fiber ones. This one did exactly what I needed, and found a need soon after it arrived. Definite addition to the tool bin.

I used these in my Dremel to cut pieces out of china plates. I will add stained glass wings and a head and make them into angels. The diamond covered drill bit worked just the way I needed it to and was very durable

I had friends tell me how great it was. This is better for shaping. Tho the cutting edge is horrible. The supposed diamond surface wore away after I touched it to the surface needing to be cut. Otherwise it has a good mandrel that is better than what comes from Dremel.

First off, I was shorted on my original order, had to put in a claim for the missing replacement parts. They shipped me a new order right away and shipped back the shorted order. Overall not happy with the whole order, you get what you pay for. I would not recommend this product.

Good product
