Diamond Burr Set- Ceramics Tile Glass Lapidary Stone Carving Sets Diamond Burs for Rotary Tools includes Dremel 50pc

Ok this is from 25 years ago, but I used the cone and ball I believe to cut a hole in a Jager bottle using a padded vice and drill press. Dremel split the glass on the first one quick, user error (made hole, started going worble-crazy), but will a nice controlled slow spin, cut through the glass cleanly. Took a while, but worked. The angle I had it at was also not ideal, so I was pretty impressed with the little cheapo's performance. Certainly the right size to get in tiny spots. Seemed like good construction then, actually enough diamonds to do something, look the same now.

These are bomb.com not cheaply made (like some can be) I've used the same piece on metals, rock, and ceramics so far... And there's no sign of wear yet 🤘 I've used my share of cheaply made bits, but these are just cheap-price and totally worth it

Nice selection of shapes. Worked well on shaping wood burning tips. Only issue so far is shaft size consistency. Some bits will not fit in my rotary tool.

Pretty good product! Great price. I recommend!

Low craftsmanship better to spend money on higher quality diamond burrs also not concentric so vibration at high speeds also causes them to wear out prematurely

just what I needed, works great.

Best burr set for price

Bits are OK for small jobs or hobby use. Used my small high speed grinder to enlarge a hole in a glass table top and completely used up a (diamond) bit in the process.

Surprisingly good quality for this price. I am pleasantly surprised It could cut through a lot of concrete.

DIAMONDS DONT LAST LONG

Todo bien, solamente llego la tapa de la caja rota

Only tried one so far and it worked very well for grinding off glaze from ceramic pieces. I’m very satisfied with my purchase.

Good quality, durable and a great assortment of burr shapes.
