Festool HSK-A 80x400 Hand Sanding Block

At a Glance: Ergonomic 80 x 400mm hand sanding block with suction power bypass adjustment, rounded burr-layer corners and integral adapter for Festool extractor hoses.

The Festool HSK-A 80x400 sanding block is a professional hand sanding solution designed for fast, controlled sanding on flat and curved surfaces. With its large 80 x 400mm sanding surface, it is ideal for covering more area by hand while maintaining good control and consistent sanding pressure. This makes it a brilliant choice for preparation work, finishing work, filler sanding, board sanding and surface refinement where machine sanding is not always practical.

The ergonomic handle with easy-grip surface helps reduce hand fatigue during longer sanding sessions, while the rounded corners on the burr layer help prevent accidental surface damage while sanding. The integrated adapter allows the sanding block to be connected to Festool extractor hoses, helping reduce dust when used with a suitable dust extractor. With bypass suction adjustment, the user can regulate the extraction strength for smoother movement and better handling on the workpiece.

Large-format Festool hand sanding block for dust-extracted manual sanding

The HSK-A 80x400 is designed for users who need the feel and precision of hand sanding, but with the advantage of Festool dust extraction compatibility. It works with compatible 80 x 400mm abrasives and is suitable for coarse, intermediate and fine sanding applications.

Extra Information

  • The HSK-A 80x400 is designed for compatible 80 x 400mm Festool abrasives.
  • The integral adapter allows the sanding block to be connected to Festool extractor hoses.
  • The bypass adapter allows suction power to be adjusted for better handling and smoother sanding.
  • Rounded corners on the burr layer help reduce the risk of surface damage while sanding.
  • The ergonomic handle is designed for comfortable use during longer sanding operations.
  • Use the correct abrasive grit for the task: coarse for removal, medium for levelling and fine for finishing.

Pro Tips

  • Use the bypass adjustment if the sanding block feels like it is gripping the surface too strongly when connected to extraction.
  • For large flat panels, sand in long overlapping strokes to maintain an even surface finish.
  • Let the full length of the sanding block stay in contact with the surface to avoid creating uneven pressure marks.
  • Change abrasive sheets as soon as they become clogged or worn; a fresh abrasive gives a cleaner finish with less effort.
  • Use extraction whenever possible, especially when sanding filler, paint or fine finishing dust.
  • Start with a coarser grit only when necessary, then work through finer grits for the best finish quality.

How to Use

  • Select a compatible 80 x 400mm abrasive sheet in the grit required for the task.
  • Attach the abrasive securely to the sanding block, making sure it is flat and aligned.
  • If dust extraction is required, connect the adapter to a compatible Festool extractor hose.
  • Adjust the bypass setting to control suction strength and sanding feel.
  • Place the sanding block flat on the workpiece before applying pressure.
  • Sand with smooth, even strokes, allowing the sanding surface to do the work.
  • Overlap passes slightly to maintain a consistent surface finish.
  • Inspect the surface regularly and change abrasive grit as needed.
  • After use, remove dust from the sanding block and check the burr layer for debris or damage.

  • Do not use worn, torn or clogged abrasives, as they can reduce control and damage the surface.
  • Keep fingers clear of sharp workpiece edges and rough abrasive surfaces during use.
  • Check the workpiece for nails, screws, staples or other metal objects before sanding.
  • Do not sand unknown coatings without confirming whether hazardous dust may be produced.
