Angle grinder accessory Dedra DED79474 abrasive disc 125 mm, P120, single pack

Dedra DED79474 abrasive disc 125 mm, P120 is an abrasive accessory designed for use with angle grinders and 125 mm sanding backing pads. This single-pack abrasive disc delivers medium-fine P120 grit suitable for light material removal, surface preparation and smoothing on metal, wood and composite materials. The disc is compatible with standard hook-and-loop (velcro) sanding pads used on 125 mm grinders and is intended for tasks where a balance between stock removal and surface finish is required.

Advantages

The P120 abrasive provides a consistent medium-fine cut that removes minor imperfections while producing a relatively smooth finish. The 125 mm diameter is a common size that fits many angle grinders and sanding backing pads, making the disc easy to integrate into existing tool setups. Supplied as a single pack, the disc is convenient for occasional work, repairs and touch-up jobs and can be used across several materials including metal, wood and composites.

Suitable for

• Smoothing and finishing wooden surfaces prior to painting or varnishing
• Light rust and paint removal on metal surfaces
• Feathering edges and preparing composite panels
• General surface preparation before bonding or filler application

When it may not be suitable

This P120 grit disc is not intended for aggressive material removal or heavy stock removal tasks; coarser grits are more appropriate where rapid cutting is required. It is also not optimal for ultra-fine finishing or polishing where finer grit abrasives or polishing pads are needed to achieve a smooth, mirror-like surface.

Key specifications

• Disc diameter: 125 mm
• Grit: P120 (medium-fine)
• Attachment: hook-and-loop compatible with 125 mm backing pads
• Pack quantity: single disc
• Suitable materials: metal, wood, composite materials

How to use

Fit the abrasive disc onto a matching 125 mm hook-and-loop backing pad on a compatible angle grinder or sanding machine, ensuring the disc is centered and securely attached. Use appropriate rotational speed recommended for the backing pad and the material you are working on. Apply light, even pressure and move the tool steadily across the surface to avoid gouging. Regularly inspect the disc for wear and replace the disc when cutting efficiency declines or the abrasive surface becomes clogged.

What to consider before purchase

• Ensure your angle grinder or sanding tool accepts 125 mm discs and uses hook-and-loop backing pads
• Confirm that P120 grit matches the required balance between removal rate and finish for your task
• Consider quantity needs: this is a single-disc pack suitable for occasional use or trialing the grit

Usage recommendations

For best results, start with a test area to verify grit performance on your material, use consistent feed motion and moderate pressure, and consider switching to coarser or finer grits depending on whether you need faster removal or a smoother finish.
