Diamond polishing pad AWTools AW CROWN M14 51mm for concrete and stone polishing

AWTools AW CROWN M14 51mm diamond polishing pad is a compact abrasive accessory designed for polishing and fine grinding of concrete, natural stone and engineered stone surfaces. With a 51 mm diameter and M14 thread, the pad mounts directly to angle grinders and small polishers to access confined areas, edges and details. It is intended for surface preparation, removing minor imperfections and achieving a smooth, polished finish on small patches, corners and profiles.

Advantages

The AW CROWN pad offers a compact size that enables precise work in tight or hard-to-reach locations where larger pads cannot operate. Its diamond abrasive provides consistent material removal and long wear life compared with non-diamond abrasives, while the M14 threaded connection ensures secure attachment to common grinders. The pad’s construction delivers controlled polishing performance for both concrete and various stone types, reducing the need for multiple tool changes during detail work.

Suitable for

• Polishing small areas, edges and profiles on concrete floors and countertops
• Removing light scratches, stains and surface imperfections from natural and engineered stone
• Surface preparation before sealing or further polishing
• Detail work around fixtures, corners and carved elements where access is limited

How to use

Fit the AW CROWN M14 51mm pad onto a compatible grinder or polisher with an M14 spindle and check that the tool is switched off and unplugged before mounting. Start work at low speed to establish contact with the surface, then increase speed as appropriate for the material and desired finish. Use light, even pressure and keep the pad moving to avoid overheating or creating uneven spots. For best results on concrete and stone, progress through finer grits or polishing stages as required by the project. Clean the surface and inspect frequently to monitor progress.

Usage recommendations

Use appropriate personal protective equipment including eye protection, dust mask or respirator, hearing protection and gloves. Where possible, use wet polishing or dust extraction to minimise airborne dust when working with concrete or stone. Match the pad grit and polishing stage to the material and desired gloss level to avoid over-polishing or glazing the surface.
