Diamond Resin Burr Kit (4 piece)

The same diamond resin 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 200, 400, 800 and 1500 (ANSI grit). Ideally suited for opal carvings (and other gemstones/materials). The shank size is 1/8" or 3.1mm.
They are the best alternative to the Diamond Pacific Nova points that I used to use and stock in the store at a fraction of the price. They do cut and polish a little differently due to the harder resin, so some adjustment is required. In essence, the harder resin makes the grinding action much faster and stronger, so care should be taken not to overshoot if you are used to Nova resin points.
 
Instructions can be found on the tool instructions page (HERE), and of course, there is plenty of extra info on the youtube channel.
