Diamond Drill Grinding Bit Set, Stone Carving Rotary Tools Polishing Kits Diamond-Coated with 1/8-inch Shank Universal Fitment for Stone Glass Ceramics

exactly what is said. has different heads and allowed me to figure out what i need. still waiting for it to burn out but it is still good

We did some yard word and added these beautiful black stones but had a bunch left over. They are small, maybe 3-5in but nicely polished. I had seen a stone engraver on Tiktock but since I already had a Dremel, this was perfect. SO many bits all for a GREAT low price. I have engraved about 6-7 rocks and it’s a lot of fun! The bits fit the Dremel perfectly and engrave the rock without hesitation. It leaves a beautiful mark on the stone as the different bits allow it to be fairly wide or fine point. I have only used 1 oval bit really, and so far it’s showing no signs of wear. A great set of bits!

Sharp and easy to use, these diamond bits work great for detail jobs. They don’t last forever but definitely get the job done.

Well priced and great for engraving stone and wood.

Used my flexible shaft machine to remove glaze from my kiln shelves using these bits. They removed the glaze drips at a controllable speed and I suspect they will last a long time. I like the variety of shapes which might be handy for fixing glaze issues on my ceramics as well.

Good bit set.

Cuts through porcelain tile, but you need to add water to the cutting area to cool the bit or it will over heat and get dull.

The obvious durability and the variety make these a one-time, satisfying purchase. I have not used them on metal, but I'm quite certain they'd hold up better than the alternatives littering Amazon.

Used this set to drill into a ceramic mug and turn it into a pot plant. The bits handled the job well precise and sharp. A handy little kit for creative projects!

A good selection of tip angle among the bits and they appear to be long lasting.. used for smoothing out damage on alloy wheel rims when caused by clumsily hitting the kerb. Better to remove the wheel to enable a good angle for the bits to work or jack up the car and turn the wheel.
