## Long description

Accessory for angle grinder Dedra DED77670 with an abrasive disc diameter of 39 cm supplied as a single piece. The abrasive disc is intended for use with compatible angle grinders for surface grinding, cutting or finishing tasks. Depending on the disc material and the angle grinder's capabilities, it can be used on metal, stone and other construction materials; verify grinder compatibility and safe operating speed before use.
Advantages
The abrasive disc offers a large working diameter that increases coverage and reduces the number of passes required for wide surfaces. Supplied as one unit, it is simple to store and replace. The design fits common angle grinder attachments and provides effective material removal when used with the appropriate disc type and correct operating parameters. Using a disc of this diameter can improve efficiency on large-area tasks while maintaining stable rotation when mounted securely.
Suitable for
Grinding and leveling large metal surfaces
Cutting or rough shaping of stone and masonry when using compatible disc types

Key specifications
Abrasive disc diameter: 39 cm
Pack quantity: 1 piece
Intended use: grinding, cutting or finishing depending on disc type
Compatible with angle grinders that accept 39 cm abrasive discs — check spindle size and maximum RPM
Material suitability: metal, stone and other construction materials depending on chosen disc composition
How to use
Before fitting the abrasive disc, ensure the angle grinder is switched off and disconnected from power. Confirm the grinder’s maximum rotational speed matches the safe RPM rating of the disc, and verify spindle and flange compatibility. Mount the disc securely following the grinder manufacturer’s instructions and tighten the flange with the correct tool. During operation, hold the grinder with both hands, apply steady pressure without forcing, and move the disc across the workpiece with controlled, even strokes. Allow the disc to cool periodically and replace it if signs of excessive wear, cracking or imbalance appear. Always follow safety guidelines and use appropriate protective equipment.
Usage recommendations
Use the abrasive disc only with angle grinders and disc types compatible with a 39 cm diameter. Select the correct disc composition for the material you are working on and respect the maximum RPM limits. Wear eye, hearing and respiratory protection, and use appropriate gloves and clothing. Inspect the disc for damage before each use and replace if compromised. Store the disc flat in a dry place away from extreme temperatures.
