6 in 60 Grit Full Face Diamond Flat Lap Disc for Glass, Stone & Lapidary Polishing

The 6" 60 Grit Full Face Diamond Flat Lap Disc provides 100% usable abrasive surface area with its center-hole-free design, engineered specifically for high-efficiency grinding and rough shaping of gemstones, glass, ceramics, and hard metals. Built on a balanced, precision-ground steel backing plate, the aggressive 60-grit industrial diamond coating ensures rapid stock removal, perfect surface planarity, and dependable long-term durability across heavy-duty lapidary and cold-working applications.

Key Features

• 100% Full-Face Abrasive Surface: No center arbor hole design maximizes surface area for grinding large flats, bevels, cabochons, and sculptural pieces without interference.
• Aggressive 60 Grit Diamond Coating: Premium electroplated industrial diamond particles deliver fast, cool stock removal on hard stones and dense materials.
• Precision Flatness: Rigid steel backing ensures true, consistent flat surfaces without crowning or edge tapering.
• Versatile Backing Compatibility: Designed for easy mounting on standard flat lap machines using magnetic master laps, PSA adhesive, or custom fixture setups.
• Wide Machine Compatibility: Compatible with 6" flat lap grinders and polishing workstations including CabKing, Covington, Hi-Tech Diamond, and custom setups.

Applications

• Lapidary & Gemstone Roughing: Rapid stock removal, pre-forming cabochons, girdle shaping, and planar flattening on agate, jasper, quartz, sapphire, jade, and petrified wood.
• Glass & Crystal Cold Working: Beveling, flattening bottle bottoms, edge smoothing, and rough stock removal on fused glass and art crystal.
• Ceramic & Metallurgy Preparation: Surface preparation, weld flattening, and coarse lapping of technical ceramics and hardened metals.

Operating Guidelines

• Always operate with a continuous water drip or coolant to flush away swarf, extend diamond life, and prevent thermal shock.
• Apply light to moderate, even pressure across the disc face; allow the aggressive 60-grit diamond particles to cut without forcing.
• Rinse the disc and workpiece thoroughly after coarse grinding to avoid contaminating finer grit stages.
