Excellent organization case

The case keeps all 102 pieces neatly sorted, which is a huge plus when you are switching between different grits frequently. The diamond bits cut through rough stone effortlessly.

Great value for the price

I was impressed by the number of accessories included. Most of the bits are high quality, though a few of the smaller felt wheels wore out quickly. Overall, a solid purchase for beginners.

Good variety of shapes

The different shapes of the grinder heads make it easy to reach tight corners in intricate designs. Just be sure to use water cooling when grinding hard stones to prolong bit life.
