Rotary tool grinding/sanding supply GRAPHITE 55H781, diameter 22.5 cm, pack of 5

GRAPHITE 55H781 grinding and sanding discs are a pack of five Velcro-backed abrasive attachments designed for rotary and extension grinders. Each disc has a diameter of 22.5 cm and a grit of K180, making it suitable for fine material removal and surface preparation on gypsum and similar substrates. The discs are perforated across the entire surface to facilitate dust extraction during sanding, and the Velcro backing ensures fast, secure replacement on compatible backing pads.

Advantages

Perforated design improves dust evacuation and helps maintain consistent abrasive contact with the work surface. K180 grit provides a balance between cutting and finishing for light smoothing, leveling, and removal of minor imperfections. Velcro fastening enables quick disc changes without tools, reducing downtime. Supplied in a pack of five, the set provides multiple replacements for small projects and routine workshop tasks.

How to use

Attach a compatible Velcro backing pad to the extension grinder or rotary tool, then press the disc onto the pad so the Velcro secures it evenly. Use the grinder at the recommended speed for the material being worked on; apply light to moderate pressure and move the tool steadily to avoid gouging. The perforations allow connection to a dust extraction system if available; otherwise work in a well-ventilated area and use appropriate respiratory protection. Replace discs when the abrasive surface shows significant wear or clogging.

Usage recommendations

For best results on gypsum and plaster, start with light passes to achieve even removal and follow with a finishing pass. Use compatible dust extraction or mask to reduce airborne dust. Store discs flat in a dry place to maintain adhesive and abrasive performance.
