Cutting Wheel Double Segment 115 mm, 22.2 mm bore — Dedra HP040

Double-segment cutting wheel 115 mm with a 22.2 mm bore by Dedra is designed for use with standard angle grinders to perform fast, controlled cutting in construction and renovation tasks. The segmented profile improves chip evacuation and ventilation during cutting, reducing friction and helping maintain cutting speed on materials commonly encountered on work sites. The wheel is intended for intermittent cutting operations where efficient material removal and cooler cutting conditions are required.

Advantages

The double-segment design provides improved ventilation and chip clearance compared with continuous-rim wheels, which supports faster cutting and reduced heat buildup. The 115 mm diameter and 22.2 mm central bore make the wheel compatible with many handheld angle grinders, allowing for precise and controlled cuts. The wheel’s segmented shape helps maintain cutting performance on masonry, concrete and similar materials while offering stability and predictable wear during repeated use.

Suitable for

• Cutting masonry and concrete blocks on construction sites
• Renovation tasks involving tile, brick or pavers
• Intermittent cutting where ventilation and chip clearance are important
• Use with 115 mm angle grinders fitted with a 22.2 mm arbor

Key specifications

• Diameter: 115 mm
• Central bore: 22.2 mm
• Segment type: double-segment (improved ventilation and chip clearance)
• Intended use: cutting of masonry-like materials
• Compatibility: designed for handheld angle grinders with matching arbor size

How to use

Fit the cutting wheel onto a compatible 115 mm angle grinder with a 22.2 mm arbor and secure it according to the grinder manufacturer’s instructions. Use appropriate guard and personal protective equipment including eye and hearing protection, gloves and respiratory protection when cutting dusty materials. Operate the grinder at the rated speed and apply steady, controlled pressure; allow the wheel to do the cutting without forcing it. Make intermittent passes when cutting thicker material to avoid overheating and to maintain chip clearance.

Usage recommendations

Inspect the wheel before each use for cracks, chips or other damage and replace if any defect is found. Use the wheel only for its intended materials and follow the angle grinder’s maximum RPM rating. For wet cutting or tasks requiring reduced dust, consider appropriate dust control measures or wheels specifically designed for wet operation.
