Diamond cutting disc Dedra Super Segment 115 mm for concrete, model H1242

Diamond cutting disc Dedra Super Segment 115 mm for concrete, model H1242 is a purpose-built abrasive blade for cutting concrete and other masonry materials. The 115 mm diameter and segmented rim geometry are designed to deliver fast cutting with controlled debris evacuation and reduced heat accumulation. The disc is intended for use with compatible angle grinders and is suitable for routine construction and renovation tasks such as trimming concrete blocks, cutting paving stones, and shaping masonry components.

Advantages

The segmented diamond rim provides efficient material removal and maintains cutting speed under load while helping to keep the cutting zone cooler. The compact 115 mm size offers good maneuverability and access in tight spaces while still providing a practical cutting depth for common on-site jobs. Constructed for compatibility with standard angle grinders, the disc balances cutting performance and durability for repetitive use on concrete surfaces.

Suitable for

• Cutting concrete blocks and panels
• Trimming and shaping paving stones and slabs
• Masonry and brick cutting on renovation sites
• Small to medium on-site concrete cutting tasks with an angle grinder

Key specifications

• Diameter: 115 mm
• Rim type: Segmented diamond rim for improved debris clearance
• Primary material application: Concrete and masonry
• Compatibility: Suitable for angle grinders with matching arbor and RPM rating
• Typical use case: Hand-held cutting operations on construction and renovation jobs

How to use

Install the disc onto an angle grinder following the tool manufacturer's instructions and ensure the arbor size and maximum RPM rating match the disc specifications. Securely tighten the mounting flange and verify the disc is free from damage before operation. When cutting, use steady, moderate feed pressure and allow the diamond segments to do the work; avoid forcing the disc. Maintain a stable stance, use appropriate cutting lines, and allow occasional pauses for the disc to cool during prolonged cuts. Always stop the grinder and disconnect power before inspecting or changing the disc.

Usage recommendations

Use approved personal protective equipment such as eye protection, hearing protection, dust mask or respirator, and gloves. For wet cutting situations, verify the tool and disc are rated for wet use; otherwise, perform dry cutting with dust extraction or local ventilation to minimize airborne dust. Store the disc in a dry, temperature-stable place away from impacts and chemicals to maintain integrity and performance.
