Preamer Cutting Burrs Editorial Review
The 18" Shank Diamond Coated Cylindrical Grinding Mounted Point Bits Burrs Compatible with Rotary Tool Bit, 4 mm Head, 10 pcs are great for enlarging holes in glass, shaping ceramic items, grinding edges of stained glass, and cutting through glass tiles. The diamond bits are coated with a fine grit which means they tend to get clogged easily and therefore require frequent rinsing and wiping during use. However, they are great for use as one of the final steps during the polishing process. The set comes in several sizes and includes a 7mm diamond burr, but sadly, all are of the same grit, and there are no different grit sizes to choose from.
