Diamond Grinding Disc AWTools AW47426, 180 mm, segmented, M14 arbor, for concrete

The AWTools AW47426 segmented diamond grinding disc is a 180 mm accessory designed for grinding and leveling concrete surfaces using handheld grinders with an M14 arbor. The disc has segmented diamond edges that facilitate efficient material removal, promote cooling, and allow debris to clear from the cutting area. It is intended for tasks such as smoothing rough concrete, removing coatings and adhesives, and preparing surfaces for further treatment.

Advantages

The segmented diamond design delivers fast stock removal while maintaining a controlled cutting action. Segments create channels that help dissipate heat and evacuate dust and debris, reducing risk of clogging and improving cutting consistency. Compatibility with an M14 threaded arbor makes the disc suitable for a wide range of handheld angle grinders. The 180 mm diameter balances working area and maneuverability for both spot work and larger surface areas.

Suitable for

• Grinding and leveling concrete floors and slabs
• Removing paint, epoxy, adhesives and surface coatings
• Surface profiling before applying coatings or screeds
• Preparing rough or uneven concrete for repair work

Key specifications

• Disc diameter: 180 mm
• Segmented diamond edge for aggressive material removal
• Arbor/thread type: M14 (threaded)
• Suitable for handheld angle grinders
• Application material: concrete and similar masonry substrates

How to use

Install the disc on a compatible angle grinder with an M14 threaded arbor following the grinder manufacturer's safety instructions. Use appropriate personal protective equipment including eye protection, hearing protection, dust mask or respirator, and gloves. Start the grinder at low speed to check balance, then apply steady, even pressure while moving the disc across the surface—avoid forcing the tool. Work in overlapping passes to achieve a uniform finish and allow cooling pauses if the disc or surface becomes excessively hot. Keep the work area ventilated or use dust extraction where possible.

Usage recommendations

For best results on concrete, use with a grinder that supports the 180 mm disc size and provide dust extraction or water suppression if the grinder and disc are rated for wet use. Match the disc to the hardness of the concrete and the required finish: segmented diamond discs are most effective for fast removal and coarse preparation, while finer-grit diamond products are better for final smoothing.
