Diamond Cutting Disc MEGA 230x22 mm for Concrete, segment 2.5x7.5 mm

Diamond cutting disc for cutting concrete, masonry and similar materials. The disc has a diameter of 230 mm, a centre hole of 22.2 mm and a blade thickness of 2.5 mm, with a cutting segment width of 7.5 mm. Designed for use on angle grinders and similar handheld cutting tools at a maximum rotational speed of 6650 rpm.

Advantages

The MEGA diamond disc provides precise, clean cuts in hard mineral materials and offers a balance between cutting speed and durability thanks to its segmented diamond rim. Its 230 mm diameter is suitable for common grinder sizes, while the 22.2 mm bore ensures compatibility with standard flanges. The 2.5 mm blade thickness and 7.5 mm segment width help reduce vibration and improve control during cutting.

Suitable for

• Cutting concrete slabs and blocks
• Cutting masonry, bricks and aerated concrete
• Making grooves and openings in walls for installations
• Outdoor and on-site construction cutting tasks with an angle grinder

When it may not be suitable

This disc is intended for hard mineral materials; it is not optimized for cutting metals, wood or plastic. For thin, precision metal work or woodworking, choose a blade specifically designed for those materials. Also avoid use at speeds above the stated maximum to prevent damage or unsafe operation.

Key specifications

• Disc diameter: 230 mm
• Centre hole diameter: 22.2 mm
• Blade thickness: 2.5 mm
• Cutting segment width: 7.5 mm
• Maximum rotational speed: 6650 rpm
• Segmented diamond rim suitable for dry and wet cutting depending on tool and conditions

How to use

Mount the disc on a compatible angle grinder with a 22.2 mm arbor and secure it with the appropriate flange and nut according to the grinder manufacturer’s instructions. Check the disc for damage before use and wear suitable personal protective equipment, including eye protection, gloves and ear protection. Use steady, even pressure and allow the diamond segments to do the cutting; do not force the disc. Maintain the grinder at correct speed and feed rate, and keep the work area clear of debris.

What to consider before purchase

• Ensure your grinder accepts 230 mm discs and has a 22.2 mm arbor or appropriate adapter
• Confirm the disc type (segmented diamond) matches your intended material and cutting method (dry or wet)
• Check maximum RPM of your tool to ensure it does not exceed 6650 rpm

Usage recommendations

For best results on concrete and masonry, use short, controlled passes and allow the disc to cool between prolonged cuts; consider wet cutting where appropriate to reduce dust and extend blade life.
