🛠️ Complete Rotary Grinding Bit Set - 40PCS, 10PCS Diamond Cutting Wheel (22mm), 20pcs Diamond Grinding Burr Drill Bits Sets, and 10PCS Abrasive Mounted Stone Grinding Wheels Bits (3mm Mandrel) Review

This is a great addition to the standard grinder set that comes with your Dremmel tool. It is excellent for grinding, cutting and polishing.

good for the price Honestly, when I first saw it I never thought it would do any of its work. I've tried metal cutting discs and they worked just great which surprised me a bit but more testing needs to be done on the whole set to rate it better!

The washers are mainly thin metal so they are better than the old washers which were bakelite. A drill is used to turn the bits. Cutting a small steel bolt with a disc was slow. I didn't use all of the bits, but they should cut through plastic without too much trouble.

They appear to be well done, but I felt they weren't done right. Necks are a bit small. They are not 3mm but 2.8 and this small difference is enough to make them useless with the wrong adapters. My first try didn't fit properly and they were unusable, but with a better adapter they worked fine although they required a little extra tightening. Overall good value for money.

I used to buy rotary tool accessories by name at my local hardware store or bought large kits that often included things I didn't need or need. I will never spend that kind of money again. This kit had all the diamond discs and cutters I needed to complete my project. These are pennies on the dollar and they work just as well as name brand accessories.

These grinders did exactly what I needed. I had several garden tools, such as an axe, a machete, . that had to be sharpened. (See attached pictures.) If I used a whetstone or file I would spend hours trying to get the edge just right. Less than ten minutes with these bits and both were sharp enough to chop down bushes and trees on the property. These pieces were a message from heaven and I highly recommend them.

I've given up my Dremel tool but I still needed a sanding attachment now and then. This set meets all my needs (used with a cordless drill). The heads work well and when the abrasives are worn out they can be thrown away as there are several pieces of each type in the set. I used to spend 6-8 dollars. US$ for a US standard grinding head (for my 3/8 inch drill bit). No longer! This kit eliminates the need for heavy 3/8" shanks (the heavier drill bits you'll find today). For the hobbyist's simple
