Flexible Diamond Resin Bonded Discs & Sheets

We purposely designed our discs without arbor holes so you can use the full surface, however if an arbor hole is required, we can provide it to you at no extra cost. You can order them with PSA (pressure sensitive
adhesive), Velcro, or Magnetic backings as separate items. Discs range in size from 1⁄2” to 24”, and PSA isstandard on 1⁄2”, 3⁄4”, 1”, and 1 1/2” discs.

All discs up to 8 inches in diameter will be supplied on Ernst (Heavyweight) for anything up to 800 Mesh and for 1200 Mesh and finer they are supplied on Carbo (Mediumweight).

Discs starting at 10 inches up to 24 inches will be supplied on our BRK (Heavyweight) material for anything up to 800 Mesh, except 1200 Mesh and finer we supply on Carbo (Mediumweight).

Our diamond resin bonded sheets we supply in 9 x 11 inch sheets and we typically provide it on Carbo (Mediumweight), however we can also provide it to you on BLT (Lightweight) material if looking for more flexibility. Sheets are sold individually not in packs.
