Diamond grinding disc 125 x 22.2 x 5 mm GRAPHITE 57H887

Diamond grinding disc 125 x 22.2 x 5 mm GRAPHITE 57H887 is a diamond-coated abrasive wheel intended for use with angle grinders that accept a 22.2 mm arbor. With a 125 mm diameter and 5 mm rim width, the disc is designed to grind, shape and profile hard materials such as natural and engineered stone, concrete and similar mineral substrates. The diamond rim provides consistent material removal and a durable cutting edge for tasks in construction, renovation and masonry.

Advantages

The diamond rim ensures effective abrasion and long service life compared with conventional abrasive discs. The 125 mm diameter and slim 5 mm rim allow for controlled edge work and precise profiling in confined or detailed areas. Balanced construction reduces vibration during operation, improving handling and surface finish consistency. The disc is compatible with standard angle grinders that use a 22.2 mm arbor, enabling straightforward mounting and replacement.

Suitable for

• Grinding and shaping natural stone and engineered stone edges
• Surface removal and smoothing of concrete and cementitious materials
• Profiling details, chamfers and grout joints in renovation work
• Removing small sections of masonry and preparing surfaces for finishing

Key specifications

• Diameter: 125 mm
• Arbor hole: 22.2 mm
• Rim width: 5 mm
• Abrasive type: diamond-coated rim
• Compatible tool: angle grinder with 22.2 mm arbor
• Typical applications: stone, concrete and similar mineral materials

How to use

Fit the disc to an angle grinder with a 22.2 mm arbor, ensuring the flange and locking nut are secured according to the grinder manufacturer's instructions. Operate the tool at the recommended speed for the disc and material, applying steady, light pressure to avoid overheating or excessive wear. Move the disc smoothly across the work surface for even material removal and maintain consistent contact angle for profiling tasks. Allow the tool to reach full speed before contact and do not force the disc into the material.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and a dust mask or respirator suitable for stone and concrete dust. Cool and clean the disc periodically if recommended for your specific grinding task, and inspect the disc for damage before each use. Ensure the angle grinder speed rating matches the disc specification and replace the disc if you observe significant wear, cracks or uneven performance.
