Diamond Vacuum-Brazed Cup Wheel Dedra DED1592S40 M14 40 mm

Diamond vacuum-brazed cup wheel Dedra DED1592S40 M14 40 mm is a compact grinding accessory designed for shaping and smoothing hard materials. The vacuum-brazed diamond layer delivers consistent cutting performance, high wear resistance and precise material removal on concrete, natural stone and other dense masonry. The M14 thread allows secure mounting on compatible angle grinders and the 40 mm diameter provides controlled access to tight areas and profiles.

Advantages

The vacuum-brazed diamond surface ensures strong bond between diamonds and the steel body, which increases durability and reduces risk of segment detachment. Its small 40 mm diameter and balanced construction enable precise work in narrow or confined spaces while maintaining stable rotation at typical grinder speeds. The M14 mounting guarantees easy attachment and reliable hold on most professional and DIY angle grinders equipped with the corresponding thread.

Suitable for

• Grinding and profiling concrete edges and corners
• Smoothing and shaping natural stone and terrazzo
• Removing small amounts of masonry material in repair and finishing work
• Detail work on stairs, thresholds and tight grooves

Key specifications

• Diameter: 40 mm
• Mounting thread: M14
• Abrasive type: vacuum-brazed diamond layer
• Recommended use: dry grinding (use depends on material and tool instructions)
• Construction: steel body with brazed diamond surface for high wear resistance

How to use

Install the cup wheel on an angle grinder with an M14 spindle following the grinder manufacturer’s instructions for secure mounting and correct flange placement. Before use, check that the wheel is undamaged and that the grinder guard and personal protective equipment are in place. Operate the grinder at recommended speeds and apply light, even pressure; avoid forcing the wheel into the material which can cause overheating or premature wear. Periodically inspect the diamond surface and remove accumulated debris to maintain cutting efficiency.

Usage recommendations

Use appropriate personal protective equipment including eye, ear and respiratory protection. For best life of the vacuum-brazed diamond surface, avoid prolonged heavy pressure and allow the tool to cool between extended passes. When working on reinforced concrete, proceed cautiously to prevent contact with rebar which can damage the diamond layer.
