Diamond cutting disc GRAPHITE 200 mm × 25.4/30 mm, Graphite model 57H870

Diamond cutting disc GRAPHITE 200 mm × 25.4/30 mm, Graphite model 57H870 is a circular abrasive tool designed for cutting mineral materials such as concrete, brick and natural stone. The disc features a continuous diamond edge that provides smooth, precise cuts and consistent performance when used on an angle grinder or stationary cutting machine with a matching arbor size. Its 200 mm diameter balances cutting depth and control for medium-duty jobs and professional applications.

Advantages

The continuous diamond rim reduces chipping at the cut edge and delivers stable cutting behavior under load. The disc construction is engineered to maintain segment integrity and to provide longer service life on abrasive materials. Dual bore compatibility allows straightforward mounting on machines with either 25.4 mm or 30 mm arbors, increasing versatility and reducing the need for additional adapters.

Suitable for

• Cutting concrete slabs and reinforced concrete (non-abrasive structural concrete)
• Cutting brick and masonry blocks
• Trimming and profiling natural stone and paving stones
• Indoor and outdoor renovation and repair tasks
• Use with hand-held angle grinders or compatible stationary cutters

Key specifications

• Disc diameter: 200 mm
• Bore options: compatible with 25.4 mm and 30 mm arbors
• Edge type: continuous diamond rim for smooth cuts
• Intended materials: concrete, brick, natural stone and similar mineral materials
• Typical use: medium-duty cutting tasks on angle grinders and stationary cutting machines

How to use

Mount the cutting disc on a compatible machine ensuring the arbor fits securely and the rotation direction matches the arrow on the disc. Tighten the flange according to the machine manufacturer’s instructions and check that the disc runs true before starting. Use appropriate cutting speed, steady feed rate and light, consistent pressure to avoid overheating. Keep the workpiece stable and use water cooling if the machine and application recommend it for dust suppression and reduced heat in the cut. Always follow the safety instructions of the power tool and wear required personal protective equipment.

Usage recommendations

Prioritize correct mounting and matching arbor size to avoid vibration and premature wear. For best cutting life and finish, use the disc on materials it is intended for and avoid side loading. When cutting reinforced concrete, make short progressive passes and allow the disc to cool between long cuts.
