Diamond Grinding Blade Dedra HP043 double-segment 230 mm diameter, 22.2 mm bore

Diamond grinding blade Dedra HP043 double-segment 230 mm diameter, 22.2 mm bore is a rotary abrasive tool intended for surface grinding, material removal and edge profiling on masonry, concrete, natural stone and similar hard materials. The blade's double-segment rim combines continuous contact with intermittent gaps to improve debris clearance and cooling during operation. It is made for use with angle grinders and surface grinders that accept a 22.2 mm arbor and a 230 mm wheel.

Advantages

The double-segment design ensures effective removal of material while maintaining controlled heat dissipation and reduced clogging. The diamond abrasive layer provides consistent wear performance and maintains grinding speed over extended periods. The 230 mm diameter delivers a balance between working width and manoeuvrability, and the standard 22.2 mm bore fits common grinder arbors for straightforward mounting.

Suitable for

• Surface grinding of concrete floors and screeds
• Removal of adhesive residues and coatings from masonry
• Profiling and levelling of natural stone and paving
• Preparing substrates for repair or resurfacing

Key specifications

• Diameter: 230 mm
• Arbor bore: 22.2 mm
• Rim type: double-segment diamond rim
• Suitable materials: concrete, masonry, natural stone and similar hard materials
• Primary use: surface grinding and material removal

How to use

Mount the diamond grinding blade on a compatible angle grinder or surface grinder with a 22.2 mm arbor and ensure the blade is secured according to the tool manufacturer's instructions. Start the grinder at low speed to verify balance, then operate at the recommended speed for the tool and blade. Use steady, even passes across the workpiece without forcing the blade; allow the diamond segments to do the cutting. Maintain a moderate downward pressure and keep the tool moving to avoid creating grooves or overheating any single spot.

Usage recommendations

For best results, use appropriate personal protective equipment including eye and hearing protection, dust mask or extraction, and gloves. When working on particularly abrasive or contaminated surfaces, consider periodic inspection of the rim and replacing the blade when wear reduces cutting efficiency. Use water cooling only if the blade and grinder are specified for wet operation; otherwise use dry grinding with adequate dust control.
