Angle grinder accessory AWTools AW47421 — diamond segmented 125 mm disc

AWTools AW47421 is a 125 mm diamond segmented disc designed as an accessory for hand-held angle grinders. It is made for smoothing surfaces and dry grinding of hard materials such as concrete, granite, marble, mortar and natural stone, offering fast material removal and the durability associated with diamond-segmented blades.

Advantages

The disc features twenty 5 mm high diamond segments that provide efficient cutting and grinding performance while maintaining wear resistance. Its 125 mm diameter makes it compatible with most standard hand-held angle grinders and suitable for routine construction and masonry tasks requiring surface preparation and material removal.

Suitable for

• Dry grinding and smoothing of concrete surfaces
• Working with granite, marble and other natural stones
• Removing mortar, adhesives and surface irregularities
• On-site renovation and masonry preparation

When it may not be suitable

The disc is intended for dry use and surface smoothing; it is not designed for wet cutting operations. For very fine polishing or precision finishing tasks a finer grit or polishing pad will be more appropriate. Also, for materials softer than stone (e.g., wood, plastics) a different blade type should be chosen.

Key specifications

• Diameter: 125 mm
• Segment type: diamond segmented
• Number of segments: 20
• Segment height: 5 mm
• Intended use: dry grinding and surface smoothing
• Compatible tool: hand-held angle grinders (standard 125 mm discs)

How to use

Mount the disc on a compatible 125 mm hand-held angle grinder following the tool manufacturer's instructions and ensure the grinder is switched off and unplugged during fitting. Wear appropriate personal protective equipment including eye, ear and respiratory protection. Use steady, controlled passes across the surface without applying excessive pressure; allow the diamond segments to do the cutting. Maintain ventilation when working indoors and clean dust regularly to reduce airborne particles.

What to consider before purchase

• Confirm your angle grinder accepts 125 mm discs and that the mounting fit is compatible
• Choose the disc for dry grinding tasks rather than wet cutting or polishing
• Plan for dust control and appropriate PPE when working with stone and concrete

Usage recommendations

Use the AWTools AW47421 diamond segmented disc on dry surfaces and for coarse material removal. Start with light passes to assess cutting rate, keep the tool speed within manufacturer limits, and replace the disc when segment wear reduces effectiveness to maintain safe and efficient operation.
