Angle grinder accessory Dedra H12H0200 — 12.5 cm diameter, 1 pc

Diamond polishing disc Dedra H12H0200 125 mm coarse grit for dry use is a tool designed for surface preparation and material removal on hard substrates such as natural stone, concrete and ceramic tiles. The disc features industrial diamond abrasive bonded to a metal or resin matrix and is optimised for dry grinding with handheld angle grinders and rotary polishers that accept a 125 mm disc. The coarse grit provides fast stock removal and effective shaping while maintaining consistent wear resistance for repeated use under dry conditions.

Advantages

The diamond abrasive delivers high cutting efficiency and prolonged service life compared with conventional abrasives when used on hard materials. Coarse grit accelerates material removal, reducing the number of passes required to achieve the desired profile. The disc is balanced for handheld operation and engineered for dry use to eliminate the need for water cooling in many surface preparation tasks. Compatibility with common 125 mm tool fittings simplifies mounting and replacement.

Suitable for

• Grinding and shaping natural stone and engineered stone
• Removing mortar, adhesive residues and surface irregularities on concrete
• Initial polishing and profiling of ceramic and porcelain tiles
• Surface preparation before sealing or coating

Key specifications

• Disc diameter: 125 mm
• Abrasive type: industrial diamond
• Grit size: coarse
• Intended use: dry grinding
• Compatible tool type: handheld angle grinders and rotary polishers with 125 mm discs

How to use

Secure the disc to a compatible angle grinder or polisher following the tool manufacturer's instructions and ensure the machine is switched off and unplugged during mounting. Operate the tool at the recommended speed range for diamond discs and apply consistent, moderate pressure to allow the abrasive to cut without overheating. Move the disc evenly across the surface in overlapping passes until the required level of stock removal or profiling is achieved. Regularly inspect the disc for wear and replace when diamond segments become ineffective.

Usage recommendations

Use appropriate personal protective equipment including eye protection, dust mask or respiratory protection, hearing protection and work gloves. Ensure adequate dust extraction or local ventilation when working in enclosed spaces, as dry grinding generates respirable dust. Avoid excessive pressure or prolonged dwell in one spot to prevent glazing of the abrasive and premature wear.
