Diamond Grinding Disc Heidmann 125 mm, 2-row segmented rim for stone and concrete

Diamond grinding disc Heidmann 125 mm with a two-row segmented rim designed for grinding and processing concrete, masonry and other mineral surfaces. The 125 mm diameter and 22.23 mm center hole make the disc compatible with standard angle grinders; the two-row segment configuration improves surface finish while maintaining efficient material removal and cooling.

Advantages

The two-row segmented rim provides faster, stronger grinding with reduced clogging and better cooling compared to continuous rims. Hardened steel core increases durability and resistance to deformation. The disc can be used wet or dry to adapt to different job-site conditions.

Suitable for

• Surface preparation of concrete and masonry
• Leveling and smoothing uneven spots
• Shaping and removing excess material on stone and concrete
• Renovation and construction site grinding tasks

How to use

Install the disc on a compatible 125 mm angle grinder with a 22.23 mm arbor following the grinder manufacturer’s instructions. Secure the disc with the correct flange and tighten to the specified torque. For dry grinding, use steady, controlled passes to avoid overheating; for wet grinding, ensure adequate water supply to cool the segments and reduce dust. Allow the disc to run at operating speed before engaging the work surface and avoid excessive side pressure.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, dust mask or respirator, hearing protection, and gloves). Match rotation direction and mounting orientation as marked on the disc. Do not exceed the maximum speed of 12,200 rpm. Store the disc in a dry place and inspect for damage before each use.
