Bosch Diamond Cup Wheel DC500 5 Inch Double Row Segmented Rim Concrete Surface Grinding Disc (7 8 In Arbor Paint Epoxy Coating Removal Masonry)

Bosch DC500 5-Inch Double Row Segmented Diamond Cup Wheel

The Bosch DC500 is a 5-inch double row segmented diamond cup wheel engineered for rapid coating removal, paint stripping, and concrete surface preparation. Featuring a medium-hard matrix bond and widely spaced synthetic diamond segments, this grinding wheel lowers operating temperatures to prevent thermoplastic paints, epoxies, and elastomeric sealers from melting or smearing on concrete substrates. Designed for 5-inch right-angle grinders and concrete surfacing planers with a 7/8-inch unthreaded arbor, it delivers smooth, balanced rotation while leveling uneven masonry, fiberglass, and cured concrete surfaces.

Best Used For:

• Thermoplastic Paint & Epoxy Removal: Stripping thick protective paints, gummy elastomeric coatings, and hard epoxies from concrete subfloors without thermal clogging.
• Subfloor Prep & Joint Leveling: Grinding down high spots, uneven slab seams, and rough masonry aggregate prior to applying new floor finishes.
• Marine Fiberglass & Resin Scaling: Smoothing weather-damaged marine fiberglass laminates, tough gel coats, and thick industrial primers.

Key Performance & Safety Features

• Thermal-Optimized Segment Spacing: Widely spaced double-row segments maintain lower operating temperatures to prevent soft coatings from melting.
• Medium-Hard Matrix Bond: Custom matrix wears continuously to expose fresh synthetic diamond grains, eliminating surface glazing.
• Industrial Synthetic Diamond Matrix: Heavy-duty diamond grit delivers aggressive cutting action across concrete, masonry, and stone.
• Precision Machine Balancing: Factory-balanced core eliminates axial wobble and machine chatter to minimize user hand fatigue and protect grinder bearings.
• Universal 7/8-Inch Arbor: Fits standard 5-inch angle grinders and dedicated concrete surfacing planers with an unthreaded 0.875-inch spindle.
• Dust Shroud Compatibility: Standard 5-inch profile integrates seamlessly with major concrete surfacing dust collection shrouds for clean, dry operation.

Technical Specifications

Pro-Tip: Maintain moderate, sweeping pressure rather than bearing down hard when stripping soft coatings; letting the wide segment spacing keep matrix temperatures low prevents tacky paint or epoxy buildup from fouling the synthetic diamond edges.
