Grinding Disc for Angle Grinder Dedra DED7749P2, 225 mm Diameter, 1 pc, Aluminium Oxide Grit

Replacement grinding disc for angle grinders, designed for general-purpose metal and wood work. The Dedra grinding disc with a 225 mm diameter and aluminium oxide abrasive is supplied as a single piece and is intended for surface preparation, deburring, shaping and removal of rust or paint in construction and workshop projects.

Advantages

The aluminium oxide grit provides a balanced combination of cutting performance and durability for common ferrous metals and softwood. The 225 mm diameter offers a broad contact area for faster material removal while retaining control during operation. As a single-piece supply, this disc is suitable for occasional replacements and small repair tasks without excess stock. The disc’s abrasive structure is appropriate for both coarse shaping and intermediate surface finishing.

Suitable for

• Removing rust and old paint from metal surfaces
• Deburring and reshaping welded joints and edges
• General metal grinding and edge dressing
• Smoothing and profiling softwood and wooden components
• Surface preparation prior to painting or coating

When it may not be suitable

This aluminium oxide grinding disc is not intended for high-speed cutting tasks that require diamond or ceramic abrasives. It may wear faster on very hard non-ferrous alloys or stainless steel compared with discs specifically formulated for those materials. For precision finishing to mirror-like surfaces or for grinding ceramics and stone, specialized abrasives should be used instead.

Key specifications

• Disc diameter: 225 mm
• Abrasive material: aluminium oxide (Al2O3)
• Quantity: 1 piece

How to use

Fit the disc to a compatible angle grinder following the tool manufacturer’s instructions and ensure the grinder is disconnected from power while mounting. Check that the disc is securely fastened and free of visible damage before use. Operate the angle grinder at the recommended speed range for a 225 mm disc, apply steady, moderate pressure and keep the disc moving across the workpiece to avoid uneven wear or heat buildup. Use appropriate coolant or intermittent operation if prolonged grinding causes excessive heat. After use, allow the disc to stop rotating completely before setting the tool down and inspect the disc for wear or damage before storing.

What to consider before purchase

• Compatibility with your angle grinder’s disc diameter and mounting system
• Suitability of aluminium oxide abrasive for the materials you will grind (ferrous metals, softwood)
• Required disc thickness and grit grade for your specific task

Usage recommendations

Use suitable personal protective equipment including eye protection, hearing protection, gloves and a dust mask. Secure the workpiece, maintain correct grinder speed and avoid excessive side pressure on the disc to prolong service life and maintain safe operation.
