Diamond Grinding Cup Wheel AWTools 180 mm — segmented, for concrete, model AW47425

AWTools Diamond Grinding Cup Wheel 180 mm (segmented, model AW47425) is designed for grinding, leveling and preparing concrete and natural stone surfaces. The wheel features a segmented diamond rim that enables effective material removal and improved heat dissipation during intensive work. Intended for use with angle grinders and compatible floor grinders that accept 180 mm wheels, this cup wheel is suitable for surface preparation tasks such as removing coatings, smoothing uneven spots and opening the substrate for subsequent treatments.

Advantages

The segmented diamond design provides rapid stock removal while maintaining consistent cutting performance. Segments increase airflow and reduce overheating, extending service life under heavy loads. The 180 mm diameter offers a balance between working width and maneuverability, making the wheel practical for both localized grinding and broader surface runs. Constructed to maintain segment stability and diamond exposure, the cup wheel achieves predictable removal rates on concrete and stone.

Suitable for

• Removing paint, adhesives, epoxy and other coatings from concrete floors
• Grinding and leveling rough or uneven concrete surfaces
• Surface preparation before sealing, coating or overlay application
• Profiling and light shaping of natural stone and masonry
• Use with angle grinders or floor grinders compatible with 180 mm wheels

Key specifications

• Diameter: 180 mm
• Design: segmented diamond rim for aggressive material removal
• Compatible tools: angle grinders and floor grinders that accept 180 mm cup wheels
• Primary materials: concrete and natural stone
• Typical applications: coating removal, leveling, surface preparation

How to use

Install the cup wheel on an angle grinder or floor grinder following the machine manufacturer’s instructions and ensuring correct flange and mounting torque. Start at low speed to verify secure installation and gradually increase to the working speed recommended for the tool and wheel. Hold the grinder with firm, steady pressure and move across the surface in overlapping passes to achieve an even finish. Avoid excessive side pressure; allow the diamond segments to do the cutting. Regularly inspect the wheel for wear or damage and replace when segments are worn beyond safe limits.

Usage recommendations

Use appropriate personal protective equipment including eye protection, respiratory protection against dust, hearing protection and gloves. For wet grinding, confirm the wheel and the power tool are rated for use with water; otherwise use dry methods with effective dust extraction to reduce airborne particles. Match grinding speed and feed rate to the hardness of the substrate to optimize life and performance.
