WORKEASE 4-inch Diamond Polishing Pad Kit — 12pc 50–6000 Grit Wet/Dry with 5/8"-11 Backer

This kit bundles eight diamond-resin pads spanning 50 through 6000 grit, two wool felt buffing pads, a hook-and-loop 5/8"-11 backer pad and an 8mm drill adapter so you can attach it to drills, grinders or polishers. Built for both wet and dry use (higher grits require water), the pads combine fast material removal at low grits with fine finishing at high grits. The resin bond and diamond matrix provide durability and consistent cutting while the wool felt pads refine final gloss.

How do these pads progress from rough to mirror finish?

The set is laid out to follow a standard polishing sequence: start with coarse grits to remove chips and heavy scratches, move through medium grits to smooth the surface, then use fine and ultra-fine grits to build gloss. Each step removes the scratches left by the previous grit, producing a progressively finer surface ready for buffing.

• 50–200 grit: aggressive stock removal and scratch correction
• 400–1500 grit: smoothing and visible sheen development
• 3000–6000 grit: ultra-fine polishing for high-reflective shine
• wool felt: final burnishing to enhance depth and luster

Which machines and attachments are compatible with the kit?

The kit includes a 5/8"-11 hook-and-loop backer pad and an 8mm drill adapter so it fits most consumer and professional rotary tools. It works with variable-speed polishers, angle grinders, electric drills and small bench polishers provided the tool speed is appropriate for the grit being used.

• 5/8"-11 threaded polishers and grinders compatible
• 8mm adapter for standard household drills included
• Recommended: use below 5000 RPM to reduce heat and prevent surface burning
• Check tool thread and variable-speed control before operation

Can I use the pads wet and dry, and when is water required?

The pads are designed for both wet and dry applications, but higher-grit pads (400–6000) perform best with water to carry away heat and swarf and to produce a cleaner, glossier finish. Dry use is acceptable for coarse grit stock removal, though it may generate dust and more heat.

• 50–200 grit: suitable for dry or wet stock removal
• 400–6000 grit: use water for optimal gloss and cooling
• Wet use reduces dust and extends pad life
• Always follow safety precautions for slurry and tool handling

What surfaces and jobs are these pads best for?

This 4" pad set is made for stone and concrete work on edges, slabs and small areas where control matters. It handles granite, marble, quartz, terrazzo, vitrified tiles, glazed tiles, natural stone and concrete countertops or flooring. Use the smaller 4-inch diameter for tight corners, sink cutouts and edge profiles where larger tools can't reach.

• Countertops, sink cutouts and edge profiles
• Small floor areas, stairs, and tile repair spots
• Restoration of chips, scratches and dull finishes
• Final polishing and buffing for high-gloss surfaces

Who is this for? The WORKEASE 4-inch diamond polishing pad kit suits homeowners doing countertop repair, tile and stone installers working on detail areas, and DIYers or professionals who need a compact polishing solution for stone and concrete. If you require controlled access to edges, sinks, or small restoration zones and want a single kit that spans coarse grinding to high-gloss finishing, this set provides the range, mounting options and wet/dry versatility to accomplish those tasks. Always verify your tool's thread and speed before use and use water with fine grits for best results.
