Review on 💎 Dremel Craftsman MTP Diamond Gemstone by Carlos Long

Great deal, lots of good parts at a very reasonable price. with a regular grinder. Ball drill bits are also great for drilling holes in glass. Haven't used the conical tips yet but they should work fine for etching/engraving. I find they work best if I cut off the bottom of a 2 liter bottle, fill it with water and sand down my piece while it's done. immersed. I use a flexible shaft to keep the water out of the way of the rotating tool and eliminate the risk of electrocution. When you first get them they will be too abrasive so sand the pieces for about a minute to break the bits. If you use the new nozzle directly on the glass, it will chew on it a little. but this only happens with new bits.
