Diamond cutting disc Smart SM-10-125S 125 mm segmented – 125mm diameter, for angle grinders

The Smart SM-10-125S 125 mm segmented diamond cutting disc is a circular abrasive accessory designed for angle grinders. It is intended for fast, efficient cutting of hard construction materials such as concrete, brick and masonry. The segmented rim profile improves cooling and helps clear debris from the cut, supporting continuous operation on building sites and renovation projects.

Advantages

The segmented diamond rim delivers rapid material removal while maintaining blade stability during straight cuts. Its design reduces heat build-up and facilitates dust and fragment evacuation from the cutting kerf, which extends useful life under heavy use. The 125 mm diameter provides a compact, maneuverable size suitable for common angle grinder models and for working in confined spaces.

Suitable for

• Cutting reinforced and non-reinforced concrete
• Brick and block cutting for masonry work
• Trimming pavers and concrete curbs
• On-site cutting during renovation and construction tasks

Key specifications

• Disc diameter: 125 mm
• Segmented diamond rim for improved cooling and debris removal
• Intended tool type: angle grinder
• Application materials: concrete, brick, masonry and similar hard building materials
• Compact size suitable for work in tight areas

How to use

Mount the disc on an angle grinder that supports 125 mm wheels, following the grinder manufacturer's instructions for flange and nut installation. Use appropriate rotation direction markings and ensure the disc is securely tightened before switching the tool on. Operate the grinder at the recommended speed and apply steady, controlled feed pressure; avoid forcing the disc through the material to prevent overheating. Allow the blade to cool periodically during extended cutting sessions.

Usage recommendations

Always wear suitable personal protective equipment including eye protection, hearing protection, gloves and a dust mask or respirator when cutting. Use water cooling only if the disc is rated for wet cutting; otherwise, use dry cutting with intermittent breaks to reduce heat. Inspect the disc for damage before each use and replace it if cracks, warping or significant segment loss are present.
