Rotary tool sanding disc set GRAPHITE 55H855, for wood, Ø 12.5 cm, pack of 3, 56 g

GRAPHITE 55H855 is a set of three fibreglass-backed sanding discs for rotary tools, designed primarily for working with wood. Each disc has a diameter of 125 mm and a coarse abrasive grain that enables effective sanding, shaping and material removal. The discs feature a close-coated alumina abrasive covering the full working surface to provide consistent cutting action and improved processing accuracy. Supplied as a pack of three, the lightweight discs are suitable for detail work, edge smoothing and preparation of wooden surfaces for finishing.

Advantages

These sanding discs offer full-surface abrasive coverage with durable alumina grains that maintain cutting performance during prolonged use. The close coating ensures even wear and efficient material removal, while the fibreglass backing provides support and resistance to tearing. The 125 mm diameter balances reach and control for detail tasks, and the set format gives users immediate replacements for continuous work.

Suitable for

• Sanding and shaping wooden surfaces
• Edge smoothing and profiling
• Removing paint, varnish or surface contaminants from wood
• Detail sanding in joinery and carpentry

Key specifications

• Abrasive type: alumina (close-coated)
• Typical grain size: coarse (suitable for material removal)
• Backing: fibreglass-reinforced disc
• Pack quantity: 3 pieces
• Intended materials: wood (also suitable for metal, plastic and putty in light grinding tasks)

How to use

Mount the disc onto a compatible rotary or angle grinder using the appropriate flexible attachment or backing pad specified for 125 mm discs. Ensure the tool is switched off and unplugged (or battery removed) during mounting. Operate the grinder at the recommended speed for sanding wood, applying light to moderate pressure and moving the disc steadily across the work surface to avoid gouging. Replace the disc when abrasive performance diminishes or the backing shows damage.

Usage recommendations

Use appropriate personal protective equipment including eye protection, dust mask and hearing protection. Test on a scrap piece before starting precision work to confirm speed and pressure settings. For best results on timber, progress from coarse to finer abrasives as you approach the desired surface finish.
