Diamond disc GRAPHITE 200 mm diameter, 25.4/30 mm arbor, model 57H871

Diamond disc GRAPHITE 200 mm diameter, 25.4/30 mm arbor, model 57H871 is an abrasive cutting wheel designed for precision cutting of hard construction materials. With a 200 mm diameter and a segmented diamond rim, this disc is intended for use on angle grinders and compatible saws when fitted with the correct arbor adapter. It is made to deliver controlled cutting performance in concrete, natural stone, ceramic tiles and masonry while maintaining wheel stability and wear resistance.

Advantages

The disc offers a balance of cutting speed and durability thanks to a diamond abrasive edge and a rigid steel core that reduces vibration. Interchangeable arbor compatibility (25.4 mm and 30 mm) provides flexibility to fit several types of grinders and saws. The segmented rim design improves cooling and debris clearance, helping to sustain cutting efficiency during prolonged use.

Suitable for

• Cutting reinforced and unreinforced concrete
• Splitting natural stone and paving slabs
• Cutting ceramic and porcelain tiles
• Trimming masonry blocks and bricks
• General renovation and construction cutting tasks

Key specifications

• Disc diameter: 200 mm
• Arbor/adaptor options: 25.4 mm and 30 mm
• Rim type: diamond segmented edge for faster cutting and cooling
• Core material: steel for rigidity and reduced vibration
• Intended materials: concrete, stone, tiles, masonry

How to use

Install the disc on a compatible angle grinder or saw using the appropriate 25.4 mm or 30 mm arbor adapter and secure it according to the tool manufacturer’s instructions. Ensure the tool is switched off and disconnected from power while changing accessories. Use the disc at the recommended rotational speed for a 200 mm diamond disc, apply steady, even pressure and allow the diamond segments to do the cutting without forcing the wheel. For wet cutting, follow tool and disc compatibility guidance; for dry cutting, avoid overheating by making short progressive cuts and allowing the disc to cool periodically.

Usage recommendations

Always wear appropriate personal protective equipment including safety goggles, hearing protection, gloves and dust mask or respirator. Check the disc for damage before each use and follow the angle grinder or saw manufacturer’s safety instructions and maximum speed ratings. Use suitable water supply or intermittent cutting to control dust and temperature when cutting dense materials.
