Diamond Segmented Cutting Disc GRAPHITE 180×22.2 mm (57H618) for Angle Grinders

GRAPHITE diamond segmented cutting disc 180×22.2 mm is designed for use with angle grinders to cut a variety of construction materials. The segmented rim layout ensures high cutting speed and efficient cooling of the blade during operation. With a 180 mm diameter and standard 22.2 mm bore, this cutting disc fits most common handheld grinders used in renovation and building tasks and is intended for cutting concrete, masonry, tiles and similar hard materials.

Advantages

The segmented diamond rim provides fast material removal while reducing heat build-up, extending blade life and maintaining consistent cutting performance. The disc construction balances durability and cutting speed to deliver reliable results on abrasive construction materials. Its standard diameter and bore make it compatible with many angle grinders, facilitating easy replacement and installation on job sites.

Suitable for

• Cutting concrete slabs and blocks
• Trimming masonry and brickwork
• Precision cuts in ceramic and porcelain tiles
• General renovation and on-site construction cutting tasks

Key specifications

• Disc diameter: 180 mm
• Bore diameter: 22.2 mm
• Edge type: segmented diamond rim for rapid cutting and cooling
• Primary materials: concrete, masonry, tiles and similar hard construction materials
• Intended tool: angle grinder (handheld)

How to use

Fit the cutting disc onto a compatible angle grinder with a 22.2 mm spindle, ensuring the disc is mounted securely and the grinder is disconnected from power during installation. Use appropriate safety equipment—safety glasses, gloves, hearing protection and a dust mask. Start the grinder and allow it to reach full speed before engaging the workpiece. Apply steady, controlled pressure and maintain the correct cutting angle; avoid forcing the disc to prevent overheating or uneven wear. For best results on thick or reinforced materials, make incremental passes rather than forcing one deep cut.

Usage recommendations

Use the disc on compatible grinders within the manufacturer’s recommended speed limits and follow local safety regulations. Keep the work area ventilated and use water suppression only if the disc and tool manufacturer permit wet cutting; otherwise, perform dry cuts with adequate dust extraction. Replace the disc when diamond segments are worn down to avoid reduced cutting efficiency and potential safety hazards.
