Description
KEYSTONE
HP MOUNTED Silicon Carbide Stone · Red Small Saucer (R-4) 12pk
Overview
KEYSTONE Red MOUNTED Silicon-Carbide STONES are the general-purpose lab-bench abrasive for everyday workflow — acrylic adjustment, plaster reduction, base-metal trimming, and other miscellaneous grinding tasks where a specialty color (green for porcelain, pink for noble metals, blue for chrome-cobalt) is not needed. The Red bond is the all-around utility option — slightly coarser than pink, slightly less aggressive than green — suitable for bench cleanup and routine tasks.
- Red silicon-carbide bond. General-purpose abrasive grade — useful across most lab grinding tasks.
- 3/32" HP shank, pre-MOUNTED. No separate mandrel required.
- Multiple head shapes including saucer geometry. Covers small-area grinding and detail contour work.
- Numbered size system (R-x). Consistent inventory ordering.
- Standard 12-pack box.
