Outstanding tools. Great for harder granites!!

When a sandstone grinding bit fails to accomplish a task with excessive wear to the bit, this diamond grinding bit will undoubtedly finish the job with little or no wear proving that the bit is of good quality. The assortment of bits offered in the received package provides a variety of different sizes when grinding different shapes and for grinding A36 steel it was not necessary to operate the rotary tool at maximum speed. When you think of the word 'diamond', high price usually follows however this set of bits was a very good value for the money.

So these bits work great, although I initially had issues with them fitting in the collet of my rotary tool (non-dremel). The shafts were too thin (1/8") and I wasn't able to tighten the collet down quite enough to hold them. Luckily, I have an older Dremel single-speed lying around, and found the collet from that worked fine. Any other bits I have bought that say "will fit Dremel" have always fit my rotary tool, so I'm not sure why these didn't.

Great value for your money (I paid around $13). I bought these to grind down ceramic glaze drips, and these bits work well. I was able to grind down about 1/2" of glaze in a couple minutes. The bit was worn out by then though. Luckily there are a lot more in the pack. The texture these leave is pretty rough obviously, so it helps to sand down your ceramic with a finer grit of sandpaper after to get a super smooth bottom.

Have been using product to carve detail in quarts. Last as long as anything I've purchased from big box stores, and this set cost as much as one individual bit from those stores. Serves their purpose well.

When i use these bits they will work fine for about a minute or so till the start sliping and cause the chuck to loosen. I know its not a problem with my dremel because i have other bits the same size that dont get loose when I use them. I also expected smaller bits but i may not have paid as good attention to the sizing. They seem to be durable but they arent my favorite.

It worked as expected

Bon produit, solides pour du petit travail, utiliser sur une pierre tombale, ras !

Perfetto

Tolle Fräser, die sich mit einem Multifunktionswerkzeug hervorragend einsetzen lassen haben und sehr gute Dienste beim Bearbeiten einer Natursteintreppe geleistet haben. Ich bin wirklich begeistert, absolutes Top-Produkt!

Me gustaron mucho, aunque las uso poco para su función lo hacen muy bien, las recomiendo
