Diamond Cutting Disc Silver 125 mm, 12159 – Cup (Garnkowa) Wheel for Angle Grinder

Diamond cutting disc Silver 125 mm, model 12159, is a cup-shaped grinding wheel designed for angle grinders and intended for work on hard building materials. With a 125 mm diameter and a cup (garnkowa) profile, this disc provides stable contact with surfaces and efficient material removal on concrete, stone, tile and masonry. It is engineered for tasks such as surface preparation, edge smoothing and small-scale removal where controlled grinding and cutting are required.

Advantages

The cup shape ensures consistent edge contact and even wear during use, improving control and reducing vibration. Diamond abrasive provides high hardness and cutting efficiency on mineral materials, delivering faster material removal compared with conventional abrasives. The 125 mm format is compact and manoeuvrable, suitable for angle grinders used in confined spaces and on detail tasks.

Suitable for

• Grinding and profiling concrete surfaces and screeds
• Smoothing and shaping stone edges
• Removing adhesive, thin mortar layers and surface irregularities on tiles
• Minor removal and preparation work on masonry and brick

Key specifications

• Disc type: cup-shaped diamond grinding/cutting wheel
• Diameter: 125 mm
• Intended tool: angle grinder
• Suitable materials: concrete, natural stone, ceramic tile, masonry
• Primary applications: surface preparation, edge smoothing, small-scale material removal

How to use

Fit the disc to an angle grinder following the machine manufacturer's instructions and ensure the tool is switched off and unplugged during mounting. Use appropriate speeds and avoid excessive lateral pressure; allow the diamond segments to do the work. Maintain steady, even movements across the work surface and avoid forcing the disc into the material to prevent overheating and premature wear. Always verify that the disc is compatible with the grinder's arbor size and maximum rotational speed before use.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, hearing protection, gloves and a dust mask or respirator. Use water cooling where feasible to reduce dust and extend disc life when working on specific materials; if dry grinding, work in well-ventilated areas and control dust with extraction. Inspect the disc for damage before each use and replace it if cracks, missing segments or wobble are present.
