Covington Resin Bond Diamond Discs
When your lapidary project moves beyond shaping and into the critical pre-polish stage, the right disc makes all the difference. Resin Bond Diamond Discs are designed to deliver smooth, consistent surfaces that prepare your stones or glass for a flawless final polish.
These discs feature a resin bond matrix that holds diamond abrasives in a softer, more flexible structure. This relaxed bond exposes fresh diamond particles as the disc wears, producing a smoother cutting action that refines surfaces without the aggressive grinding marks left by harder bonds. The result is a beautifully even pre-polish that dramatically improves the quality of your final finish.
Magnetic backing allows the discs to snap onto your steel lap plate in seconds, making grit changes quick and effortless during multi-stage grinding and polishing. This saves time at the machine and keeps your workflow efficient.
Designed with a 1" center hole, each disc easily aligns on your steel plate to ensure stable, accurate operation during use.
