Angle grinder accessory Dedra DED7749P50 – sanding disc Ø225 mm, grit 220, Al2O3, 1 pc

Dedra DED7749P50 sanding disc Ø225 mm, grit 220, made from aluminium oxide (Al2O3) is an accessory for angle grinders designed for moderate material removal, surface preparation and finishing. The single disc format fits 225 mm backing plates and is intended for use on wood, metal and painted or coated surfaces where a consistent medium-fine abrasive is required. The disc’s aluminium oxide grain offers durability and balanced cutting action for both stock removal and smoothing tasks.

Advantages

The Dedra sanding disc combines a 225 mm working diameter with a 220 grit abrasive to deliver a mid-to-fine surface texture. Aluminium oxide abrasive provides wear resistance and a stable cutting rate across mixed materials. Supplied as a single piece, it is convenient for replacement during refurbishment, paint preparation or metal finishing jobs and is compatible with standard perforated or solid backing systems sized for 225 mm discs.

Suitable for

• Sanding and smoothing wooden boards, panels and furniture parts
• Light to moderate metal deburring and surface blending
• Paint and coating removal or preparation before repainting
• Finishing between work stages where a 220 grit surface is required

When it may not be suitable

This 220 grit aluminium oxide disc is not intended for very coarse stock removal where lower grits (coarser) would be more effective; it offers slower removal on heavy welds or thick coatings. It is also not designed for precision finishing tasks that require ultra-fine grits or polishing pads.

Key specifications

• Disc diameter: 225 mm
• Abrasive grit: 220 (medium-fine)
• Abrasive material: aluminium oxide (Al2O3)
• Quantity: 1 piece
• Intended use: wood, metal, painted/coated surfaces

How to use

Mount the 225 mm sanding disc onto a compatible angle grinder backing pad according to the grinder manufacturer’s instructions and ensure the disc is centered and secured. Use appropriate rotational speed for the material and apply even, light-to-moderate pressure while moving the tool steadily to avoid gouging. Keep the grinder moving across the surface to maintain uniform abrasion and change the disc when blunt or clogged to preserve consistent cutting performance.

What to consider before purchase

• Confirm your angle grinder/backing pad supports 225 mm sanding discs
• Ensure 220 grit matches the required surface finish and material removal rate
• Verify aluminium oxide is appropriate for the materials you will work on

Usage recommendations

Use personal protective equipment including eye protection, dust mask and hearing protection. For painted surfaces, ensure compatibility with substrate and coatings; test on a small area first. For dust control, use a vacuum extraction system or work in a well-ventilated area.
