03 Key Features

Built for the job site.

// 01
Flat head — surface polishing focus
Flat grinding head distributes pressure uniformly across the disc — produces consistent surface finish on large plate areas, rather than the spot wear of angle-grinder discs on flat work.
// 02
10,000 – 13,000 r/min spindle
Higher RPM than angle grinders gives faster material removal on rust, paint and oxide layers. Standard tool for surface prep before coating application.
// 03
Spark-free pneumatic
Safe for damp, dusty and hazardous-area work where electric tools introduce ignition or shock risk.
// 04
Light (1.5 – 2.5 kg) — overhead capable
Sized for overhead and vertical surface work where heavier angle grinders cause operator fatigue. Bulkhead, beam and underside polishing.
