VR 561 Aluminium Oxide Resin Fiber Disc

The VR/FR 561 is a premium aluminium oxide fiber disc on vulcanised fiber backing, made for deburring, light material removal, and finishing on mild steel and sheet metal fabrication. Jumbo-coated grain coverage means more cutting points per square centimetre — the disc works the surface evenly without the operator having to compensate for uneven grain distribution with increased pressure.

Product Information

Benefits

- Even grain distribution delivers consistent material removal across the full disc face

- No dead zones that force the operator to rework the same area

- Vulcanised fiber backing provides rigidity under grinding pressure without cracking or delaminating

- Close coat construction gives the cutting density needed for clean deburring on mild steel edges and weld toes

Advantage

- Jumbo coating increases active grain coverage over standard coated fiber discs

- More material removed per disc, lower cost per component on sheet metal fabrication lines

Features

- Premium aluminium oxide grain on 0.8mm/0.6mm vulcanised fiber backing with close coat

- Jumbo coating for maximum grain coverage and even cut across the disc face

- Compatible with standard angle grinder backing pads for MS and sheet metal fabrication
