Sintered Diamond Burr 10 Piece Kit (Assorted Grits)

The same sintered diamond burrs that I use on the Roys Rocks YouTube channel (https://www.youtube.com/c/RoysRocks).
 
This set covers a wide range of grits including 80, 90, 120, 240 and 600 (ANSI grit). Perfectly suited for opal carvings (and other gemstones/materials). The shank size is 3/32" or 2.38mm.
They are an absolute powerhouse and will outlast many sets of electroplated diamond burrs and may even last a lifetime with proper use. I've used mine daily now for multiple years with little signs of wear.
 
Instructions can be found on the tool instructions page (HERE), and of course, there is plenty of extra info on the youtube channel.
