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.

Have only used a couple so far and they worked well. Took a little longer to get here but ok cause when they got here they worked.

These hold up well for how cheap they are. Fit my corded Dremel and I used to grind concrete down in some tight spaces.

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.

I absolutely love these bits with my Dremel on resin crafts!

Works great and nicely packed

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
