Diamond cutting disc 230 x 22.2 mm GRAPHITE 57H638 — for stone, concrete, tile

The Diamond cutting disc 230 x 22.2 mm GRAPHITE 57H638 is designed for efficient cutting of hard mineral materials. With a 230 mm diameter and 22.2 mm bore, the disc fits angle grinders and bench saws with compatible flanges and is intended primarily for cutting stone, concrete, masonry and ceramic tiles. Its diamond-segment construction ensures precise, controlled cuts and durability during construction and renovation tasks.

Advantages

The diamond-segment edge provides fast material removal while maintaining a consistent cutting line. The disc construction is optimized for heat dissipation and reduced vibration, which helps extend cutting performance and improve operator control. Compatibility with common 22.2 mm bore power tools makes the disc easy to install and replace for professional and DIY use.

Suitable for

• Cutting natural and engineered stone
• Cutting concrete and reinforced concrete elements
• Masonry and brick cutting
• Cutting ceramic and porcelain tiles

Key specifications

• Diameter: 230 mm
• Bore: 22.2 mm
• Intended materials: stone, concrete, masonry, ceramic tiles
• Segmented diamond rim for dry or wet cutting (depending on equipment)
• Designed for use with angle grinders and bench saws with matching flange

How to use

Install the disc on an appropriate power tool following the tool manufacturer’s instructions and ensure the flange and mounting surfaces are clean and secure. Use recommended rotation direction markings on the disc. For best results, select a suitable cutting speed and apply steady, even pressure without forcing the disc. Use appropriate personal protective equipment including eye, hearing and respiratory protection. When possible, use water cooling to reduce dust and heat; if dry cutting, take frequent breaks to allow the disc to cool.

Usage recommendations

Check the compatibility of the disc with your tool’s maximum RPM rating before use. For reinforced concrete and very abrasive aggregates, prefer slower feed rates and consider wet cutting to prolong disc life. Store the disc flat in a dry place and avoid impacts that can damage the diamond segments.
