VSM CP501 Silicon Carbide Sandpaper Disc – 7 in. x 7/8 in. Arbor, 120 Grit, 100 per Box
VSM CP501 Silicon Carbide Sandpaper Disc – 7 in. x 7/8 in. Arbor, 120 Grit, 100 per Box
The VSM CP501 Silicon Carbide Sandpaper Disc is a 7 in. disc used to sand and refine stone, glass, ceramic, composite, steel and wood, in 120 grit with a 7/8 in. arbor hole, supplied 100 per box. VSM publishes the CP501 line as a silicon carbide grain on an E-Paper backing, full-resin bonded and close coated. In this range 120 grit is a medium disc that takes out the coarse scratch pattern.
This is a coated abrasive on a paper backing, not a diamond disc. It sands and refines a surface; it will not grind hard stone flat or take out a saw cut. For that, use a diamond tool — the SIERRA Resin-Filled Diamond Cup Wheel, 4 in., for grinding, or the Alpha Ceramica Resin Wet Polishing Disc for wet polishing. Note also that this size has a plain 7/8 in. arbor hole rather than a hook-and-loop face, so it does not mount on a hook-and-loop backer pad — the 4 in. and 5 in. CP501 discs are the hook-and-loop version.

Frequently Asked Questions
What does it mount on?
VSM publishes no attachment method for the 7 in. discs beyond the 7/8 in. arbor hole, so no backing claim is made here. Confirm the pad or backing plate on your machine before ordering.
What is E-Paper?
VSM's paper weight code. E-Paper is approximately 250 g/m2 and VSM specifies it for hand surface grinding. It is the backing VSM publishes for the whole CP501 line, and it is where the trailing E in old catalogue grits such as 120E came from — that letter was the paper weight, not part of the grit.
Is this CP501 or CP501K?
CP501. VSM publishes no product called CP501K. The part list reads "CP501 SAOK", and the CP501K code came from running the line name together with the suffix.
What materials does VSM recommend it for?
VSM lists unalloyed steel, composites, glass, stone and ceramic, and wood, with lacquer as a secondary material.
How many discs do I get?
Each box holds 100 discs.
