Diamond cutting disc 230 x 22.2 mm GRAPHITE 57H630 — wet/dry cutting, segment rim

GRAPHITE 57H630 is a 230 x 22.2 mm diamond cutting disc with a segmented rim designed for cutting hard construction materials. The disc is made for use on angle grinders with a 22.2 mm bore and supports both wet and dry cutting methods. Its segmented diamond rim ensures efficient material removal and helps maintain controlled cutting speed when working with masonry, concrete, brick and similar materials.

Advantages

The segmented diamond rim provides fast cutting and effective debris clearance, reducing overheating during extended use. Compatibility with wet and dry cutting methods adds versatility on site and in workshops. The 230 mm diameter combined with a standard 22.2 mm bore makes this disc compatible with many common angle grinders, while the reinforced core improves stability and reduces vibration for straighter cuts.

Suitable for

• Masonry and block cutting
• Concrete slab and curb trimming
• Brickwork modifications and openings
• Cutting paving stones and kerbstones
• General construction demolition and renovation tasks

Key specifications

• Diameter: 230 mm
• Bore: 22.2 mm
• Rim type: Segmented diamond rim
• Cutting methods: Wet and dry
• Primary materials: Masonry, concrete, brick, similar hard materials

How to use

Fit the cutting disc onto an angle grinder with a matching 22.2 mm arbor and ensure the fastening flange is tightened according to the grinder manufacturer's instructions. Before full-depth cutting, make a shallow test cut to confirm alignment and cutting behavior. For dry cutting, use steady, moderate feed pressure and allow the disc to cool periodically; for wet cutting, ensure a consistent supply of water to the cutting zone to reduce dust and heat. Always follow the maximum RPM rating of the disc and avoid side loading or twisting motions that could damage the segmented rim.

Usage recommendations

Wear appropriate personal protective equipment: eye and hearing protection, gloves and a dust mask or respirator when dry cutting. Maintain even pressure and avoid forcing the disc; allow the diamond segments to cut at their designed pace. For prolonged cutting tasks, prefer wet cutting where possible to extend disc life and improve dust control. Inspect the disc for cracks or excessive wear before each use and replace it if any damage is visible.
