Diamond grinding disc for concrete MODECO MN-78-413, 125 mm

Diamond grinding disc for concrete MODECO MN-78-413, 125 mm is an abrasive accessory designed for surface preparation and finishing of concrete substrates. Made for use with standard 125 mm angle grinders, this disc is intended to remove laitance, level small unevenness, clean joint edges and prepare screeds for subsequent coatings or polishing. The tool is suitable for coarse to medium grinding tasks in construction, renovation and maintenance work where controlled material removal and consistent surface texture are required.

Advantages

The diamond segments provide efficient cutting performance and longer service life compared with conventional abrasive discs. The 125 mm diameter makes the disc compatible with a wide range of angle grinders and enables access to confined areas. Designed for concrete, the disc delivers consistent material removal while minimizing vibration and heat build-up during normal operation.

Suitable for

• Preparation of concrete floors and screeds before applying coatings
• Removal of surface laitance, thin mortar residues and minor imperfections
• Grinding around joints, edges and hard-to-reach areas with a 125 mm grinder
• Coarse to medium material removal during renovation and repair work

Key specifications

• Diameter: 125 mm
• Type: diamond grinding disc for concrete
• Compatible tool: 125 mm angle grinder
• Application grade: coarse to medium grinding
• Typical uses: surface preparation, smoothing, joint and edge work

How to use

Mount the disc securely on a compatible 125 mm angle grinder following the machine manufacturer's instructions and safety procedures. Operate the grinder with steady, even passes across the concrete surface, avoiding excessive pressure that could overload the disc or the tool. Begin with light passes to assess material removal rate and adjust grinding pressure or overlap as needed to achieve a uniform finish. Use appropriate coolant or dust extraction where applicable to control dust and reduce wear.

Usage recommendations

Always wear suitable personal protective equipment including eye protection, hearing protection, respiratory protection and gloves. Ensure the grinder is switched off and unplugged when fitting or removing the disc. Use dust extraction or a vacuum attachment to reduce airborne silica dust when grinding concrete and follow local occupational safety regulations.
