Angle grinder accessory Dedra H12G0400 — diameter 12.5 cm, 1 pc

Dedra 125 mm diamond flexible polishing pad with 400 grit is designed for controlled polishing and finishing of hard surfaces such as natural stone, engineered stone, concrete and similar materials. The flexible diamond surface conforms to slight contours while delivering consistent abrasive action, making it suitable for both initial smoothing and final finishing steps. The pad is intended for use with rotary and angle polishing tools that accept 125 mm backing plates and provides predictable material removal with a focus on surface quality.

Advantages

The flexible diamond layer ensures even contact with uneven surfaces, reducing the risk of localized over-polishing. A 400 grit abrasive offers a medium-fine finish that removes minor scratches and prepares surfaces for subsequent finer polishing stages. Compatibility with standard 125 mm tool backings simplifies attachment to a wide range of rotary and angle polishers. The pad construction balances durability and flexibility for consistent performance during extended use.

Suitable for

• Polishing and finishing natural stone surfaces such as granite and marble
• Smoothing and refining concrete and engineered stone
• Intermediate polishing stage between coarse grinding and fine polishing
• Use with 125 mm backing plates on rotary or angle polishers

Key specifications

• Diameter: 125 mm
• Abrasive type: diamond
• Flexibility: flexible/following surface contours
• Abrasion grade: 400 grit (medium-fine)
• Intended materials: stone, concrete, engineered stone and similar hard surfaces
• Tool compatibility: rotary and angle polishing tools with matching 125 mm backing

How to use

Attach the polishing pad to a compatible 125 mm backing plate on a rotary or angle polisher, ensuring secure fastening before operation. Begin polishing at low speed to establish contact and control heat build-up, then increase speed as appropriate for the material and tool. Move the tool with steady overlapping passes, applying light to moderate pressure and keeping the pad flat to avoid edge wear. Regularly inspect the surface and the pad condition; clean or replace the pad if performance declines or if abrasive loading occurs. Progress to finer-grit pads after achieving the desired intermediate finish.

Usage recommendations

Use water cooling or intermittent operation on heat-sensitive materials to minimize thermal damage and extend pad life. For best results, follow a stepwise polishing sequence from coarser to finer grits and match pad speed and pressure to the specific stone or concrete type.
