Specs

3/32" shank - the size most Foredom and Dremel rotary tools take. On a Dremel, use the 3/32" collet.
Keep them wet. Water or Gem Lube on small work, a damp sponge held to the stone on big pieces. Run one dry, even for a moment, and the resin melts and the point is finished.
Two head shapes. Bullet for grooves, corners and undercuts. Rounded cylinder for sweeps, flats and the inside of a bowl. Each one comes small or large.
The colour tells you the grit. Green is 60, rust 140, black 280, brown 600, grey 1,200, rose 3,000, tan 8,000, cream 14,000 and light blue 50,000.
The Set is four points in one shape and size: 280, 600, 1,200 and 3,000. That is Diamond Pacific's own sanding order. Finish with 8,000 or 14,000 for a wet shine.
They sand and polish. They do not shape. Grind the form first, then work up through the grits.
Small marks in the resin are normal on a new point. They do not change how it cuts.
Wear safety glasses. Diamond Pacific publishes no speed setting for these - keep the point wet and let the diamond do the work.
