Angle grinders generate high dust loads, especially with masonry and concrete. A well-fitted shroud turns the grinder into a controlled system by capturing dust at the disc before it can disperse.

The components that matter

A typical shroud includes an adjustable collar to suit the guard, a rigid body with an extraction port, and a brush skirt that seals to the surface. Some models have swing or cut-out segments to reach edges. Connect to an H-Class vacuum via an antistatic hose.

Set-up for capture

Choose a shroud matched to disc size and guard style. Check that the brush skirt touches the surface evenly without dragging. Keep hose runs short and avoid tight bends. MAXVAC-compatible shrouds are commonly used with H-Class extractors to maintain capture during heavy grinding.

Technique during grinding

Start with the shroud flat so the skirt seals. Advance steadily; do not rock the tool. For edges, use the swing segment only as needed and slow your pass to keep capture. If you must plunge, lower the disc gently, re-seal the skirt, then continue the cut.

Maintaining performance

Empty the bin before suction tails off. Use pre-filters where available and clean or change filters per site conditions. Inspect the brush skirt for wear; a split or short skirt leaks dust. Confirm performance with a quick visual check or a handheld PM meter.

Practical takeaways

  • Fit the correct shroud and seal the brush skirt to the surface.
  • Use an H-Class vacuum with short, straight, antistatic hose runs.
  • Grind with steady passes; slow down at edges to maintain capture.
  • Maintain filters and replace worn skirts to prevent leakage.
  • Spot-check with a PM meter to confirm control during work.

This simple set-up reduces visible dust, keeps the workspace clearer, and supports compliance when working on silica-containing materials.
