Diamond Grinding Disc AWTools AW47422 — 125 mm, M14 segmented, for concrete

Diamond Grinding Disc AWTools AW47422 — 125 mm, M14 segmented, for concrete is a 125 mm diameter segmented diamond disc engineered for use on concrete surfaces with angle grinders and concrete grinders. The disc’s segmented rim is designed for efficient material removal, enabling surface preparation, leveling and removal of coatings, adhesives or irregularities on concrete slabs, screeds and sidewalks. Its construction supports both dry and wet grinding, allowing dust reduction and cooling when water is applied.

Advantages

The segmented diamond rim ensures fast cutting and aggressive grinding while maintaining durability and consistent performance across the disc. The 125 mm diameter and M14 thread make it compatible with a wide range of handheld angle grinders and smaller floor grinders, offering controlled handling and access to tight areas. The design allows for both dry work with dust control and wet operation for reduced heat and prolonged segment life.

Suitable for

• Surface preparation of concrete floors and slabs
• Removal of thin coatings, paint and adhesives from concrete
• Leveling uneven concrete and smoothing rough patches
• Grinding edges, corners and small repair areas

Key specifications

• Disk diameter: 125 mm
• Mounting thread: M14
• Segment type: Segmented diamond rim for aggressive material removal
• Compatible materials: Concrete and similar mineral surfaces
• Operation modes: Suitable for dry and wet grinding

How to use

Mount the disc onto a compatible grinder with an M14 arbor, ensuring the tool is unplugged or its battery removed during installation. Check that the disc is securely fastened and that the grinder’s guard and safety features are in place. Start grinding with moderate pressure, allowing the diamond segments to do the work; avoid excessive force which can overheat the disc or damage the surface. For dust control and extended segment life, use water when the tool and worksite conditions permit. Follow the grinder manufacturer’s speed and safety recommendations.

Usage recommendations

The disc is intended for use on concrete and similar mineral materials; select an appropriate grinder speed and apply even, controlled passes. Use personal protective equipment—safety glasses, gloves, respirator or dust extraction—and follow local safety regulations when performing dry grinding. For improved finish and lower dust, use wet grinding where feasible. Inspect the disc before each use for damage and replace if segments are worn or the bond is compromised.
