Product Information

Full details

The Scheppach HMS850 Planer Thicknesser is an ideal solution for hobbyists and DIY woodworkers looking to achieve professional-grade timber surfacing in a home workshop setting. By combining a surface planer and a thicknesser into one compact 1250W benchtop unit, it allows users to precisely flatten and dimension stock up to 204mm wide. While it offers impressive efficiency for small to medium projects, users should be aware that as a benchtop machine, it is designed for lighter-duty tasks and requires careful management when handling very long or heavy hardwood boards.

FAQs

What is the maximum thickness capacity of the HMS850?

The machine can thickness boards up to a maximum height of 120mm.

Can I sharpen the blades myself?

While HSS blades can be honed, for optimal results and safety, it is recommended to replace them or have them professionally sharpened.

Do I need a dust extractor?

Yes, using a dust extractor with the HMS850 is strongly advised to maintain visibility and prevent motor blockages from wood chips.

Is this tool suitable for hardwoods like Oak or Walnut?

Yes, it can handle hardwoods, but you must take shallower passes to prevent overheating the motor and blunting the blades.

How do I switch between planing and thicknessing modes?

The transition involves moving the dust extraction hood and adjusting the table configuration as outlined in the provided owner's manual.

Troubleshooting

Snipe or gouging at the start or end of the board

Support the board as it enters and leaves the machine, ensuring the workpiece remains perfectly level with the feed bed.

Rough or uneven surface finish

Inspect the blades for chips or resin buildup. Clean with a dedicated solvent or sharpen/replace the HSS blades.

Motor stalling during a pass

Reduce the depth of cut for the current pass. Avoid forcing material through the machine too quickly.

Pros and Cons

Pros

  • Compact footprint ideal for small workshops
  • Efficient 2-in-1 functionality saves workspace
  • Reliable 8000rpm blade speed for smooth finishes
  • Simple manual height adjustment for ease of use

Cons

  • Limited to a 204mm planing width
  • Designed primarily for lighter-duty workshop tasks
  • Requires careful stabilization to prevent movement during heavy cuts

Setup, Compatibility & Care

Setup of the HMS850 is straightforward: ensure the unit is bolted securely to a stable workbench to minimize vibration during operation. The machine is compatible with standard 230V power outlets.

For care and maintenance, always disconnect the power before performing adjustments or cleaning. Periodically inspect the twin HSS blades for dullness or nicks, as sharp blades are essential for preventing 'snipe' (a slight gouge at the end of a board). Keep the internal feed rollers clean of resin buildup using a specialized resin remover to ensure the 6m/min feed rate remains consistent. Dust extraction is highly recommended; connect a suitable workshop vacuum to the integrated dust port to keep the cutting area clear of debris.
