Diamond Cutting Disc 125 x 22.2 mm (Segmented) — Hoegert HT6D751

The Hoegert Diamond Cutting Disc 125 x 22.2 mm (Segmented) HT6D751 is a segmented diamond blade designed for angle grinders and intended for cutting hard construction materials. With a 125 mm diameter and a 22.2 mm bore, this disc is made to deliver efficient, controlled cutting of concrete, masonry, tiles and natural stone. The segmented rim promotes faster material removal and improved cooling to reduce heat build-up during intensive cutting tasks. The disc can be used for both wet and dry cutting depending on the specific job and operator preferences.

Advantages

The segmented diamond rim provides accelerated cutting speed while maintaining durability and a longer service life compared with conventional abrasive discs. Improved ventilation between segments helps dissipate heat, reducing the risk of overheating and blade distortion during prolonged operation. Compatibility with standard 22.2 mm angle grinder flanges makes the disc easy to mount and suitable for common handheld grinders used in construction and renovation. The design balances cutting performance and chip clearance for consistent, controlled cuts in a variety of hard materials.

Suitable for

• Cutting concrete and reinforced concrete
• Cutting masonry blocks, bricks and pavers
• Trimming ceramic and porcelain tiles
• Shaping and cutting natural stone and granite
• On-site renovation and construction cutting applications

How to use

Mount the diamond cutting disc on an angle grinder with a 22.2 mm arbor and secure it according to the grinder manufacturer’s instructions. Inspect the disc for damage before use and wear appropriate personal protective equipment including eye protection, gloves and hearing protection. For dry cutting, operate the grinder with steady, moderate feed pressure to avoid overheating; allow the disc to cool periodically during extended cuts. For wet cutting, apply a controlled water supply to the cutting line to reduce dust and further cool the blade. Follow safe cutting practices and avoid lateral side loads that could damage the diamond segments.

Usage recommendations

Use the segmented diamond disc for medium- to heavy-duty cutting tasks where speed and cooling are important. For finishing or precision tile work, consider a continuous-rim or fine-grit diamond blade. Regularly check the disc for wear and replace it when diamond exposure or segment loss affects cutting performance.
