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.

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!

These work but aren’t the best. For the price I suppose they are okay.

I wanted to etch some memory stones for family members who recently passed away. These bits were just what I needed to do just that. They work great!

They work good when they are fresh. I've cut all kinds of patterns into rocks with them from simple crosses to humming birds. but they wear out fast.

Been using them a lot, they do wear down fast but no faster than the official pieces imo and works really well considering to get the same set with dremel it would cost your soul so for the price they are great.

No nos engañemos, los productos chinos son de baja calidad, ni siquiera dirÃa media. Estas fresas de diamante cumplen su función pero no esperes durabilidad, hacen su trabajo suficientemente bien pero no los puedes forzar ni un poco. Para madera, metal blando y no férrico y algunas piedras de media dureza sirven, pero si quieres trabajar en serio compra producto europeo o de USA, mucho más caro pero fiable. Para practicar y no gastar demasiado entonces este producto te sirve.
