12" 14000Grit Resin Diamond Smoothing Pad – Magnetic Backing for Flat Lap Grinding & Polishing

The Diamond Smoothing Pad is engineered for large-scale pre-polishing and surface refinement of fragile yet super-hard materials like glass, ceramics, crystals, and natural stone. Made with high-concentration resin-bonded diamonds, it delivers rapid removal of grinding marks and high spots—outperforming traditional silicon carbide discs and messy diamond compound systems. Available in a full grit range from 60 to 50000, this pad features a strong magnetic backing for instant, tool-free attachment to most flat lap grinders.

Application

Ideal for lapidary artists, glass studios, and precision fabricators, these diamond smoothing pads excel at pre-polishing flat surfaces before final buffing. Use them to refine stone slabs, smooth glass edges, or prepare ceramic tiles for high-gloss finishes. Simply start with coarse grits (e.g., 60–280) to level the surfaces, then progress through medium (600–3000) to ultra-fine grits (8000–50000) for a mirror-like result. Works wet or dry—though water lubrication is recommended to extend pad life and reduce heat buildup.
