NGe 10 Pcs 10mm Cylinder Head Diamond Coated Mounted Points Grinding Bit - 3mm Shank

I used these to help do the fine tuning of a tile install in my bathroom. These bits made quick work of the ceramic tile and left very smooth edges which I really like since I don't want sharp edges near the PEX pipe. Great value for way more bits than I need.

Durable, cuts through glass like hot knife in butter.Downside is that grit is too coarse and chips glass badly on the side if pressed against.needs special attention not to chip too much, but will chip glass edges anyway.overally, this is a go if you can tolarate some chiping

Though there was at first some skidding due to the flatness of the head, I was able to drill through a 1/4" beach rock using this bit. Made for a cool necklace pendant. Quite pleased.

Great

I use this product to engrave stone, and it lasts longer than other brands I have used for the same purpose. Good value for the money. I would purchase again, but would prefer if they were made in the USA.

If you’re buying these as a groomer don’t. They get hot so fast and take twice as long to file down the nail.

I'm a professional dog groomer and I have found that dogs seem to mind this type of dremel head much less than the traditional sand paper type. I think because the grit is finer it doesn't feel as harsh on their nails.

Use these for my dogs nails. They work well.
