Angle grinder accessory Dedra H1161-45 — cutting/flange disc Ø45 mm, 1 pc

Dedra H1161-45 is a diamond cutting disc for concrete with a 450 mm diameter and a 25.4 mm bore designed for use on large abrasive saws and masonry cutters. It is intended to deliver efficient straight cuts in concrete slabs, curbs and other concrete elements on construction and renovation sites. The disc’s dimension and construction make it suitable for heavy-duty cutting tasks where consistent performance and stability are required.

Advantages

The diamond segment composition provides high cutting speed and extended life compared with conventional abrasive wheels while maintaining straight, clean cuts in reinforced and non-reinforced concrete. A 25.4 mm bore ensures secure mounting on compatible professional saws and reduces runout for improved accuracy. The 450 mm diameter allows deeper cutting depths for thick slabs and curbs, reducing the number of passes needed for full-depth cuts.

Suitable for

• Cutting concrete slabs and floor panels
• Trimming and cutting curbs and pavements
• Making straight cuts in reinforced and non-reinforced concrete
• Use with large abrasive saws and masonry cutters on construction sites

Key specifications

• Diameter: 450 mm
• Bore (arbor) diameter: 25.4 mm
• Material capability: concrete (reinforced and non-reinforced)
• Designed application: straight cutting with large abrasive saws and masonry cutters
• Suitable for wet and dry cutting where compatible with the machine and local safety guidelines

How to use

Mount the diamond cutting disc on a compatible large abrasive saw or masonry cutter with a 25.4 mm arbor, following the machine manufacturer’s instructions for secure fastening and correct rotation direction. Check the disc for damage or cracks before each use and ensure the saw’s guards and safety devices are in place. When cutting concrete, set the cutting depth and progress steadily; allow the disc to work at its own pace without excessive feed pressure to avoid overheating or premature wear. Use appropriate personal protective equipment including eye, ear and respiratory protection.

Usage recommendations

For prolonged blade life and optimal cut quality, match the cutting speed and feed rate to the concrete hardness and reinforcement, use periodic cooling or wet cutting if the machine supports it, and perform regular inspections for segment wear and wheel integrity.
