The timber construction all-rounder.

Whether you are cutting solid timber, doing joining work, cutting planks, square timber or boards, sawing tenons or cutting panel materials of all types – the robust 2300 watt HK 85 ideally combines performance with ease of use. Combined with unique accessories such as the adjustable groove cutter, the HK 85 is the reliable all-rounder for timber construction.

  • High-torque 2300 W motor with power electronics ensures constant power when sawing
  • Safe and easy handling thanks to the cutting depth adjustment with plunge function, pendulum hood remote control and guide wedge
  • Angle adjustment with central clamping mechanism from 0 to 60 degrees
  • Using the conversion kit accessories, the portable circular saw can become a groove cutter
  • In conjunction with the trimming rail, fast, accurate and mobile cross cuts
  • Safe and perfectly straight sawing along the guide rail

Product highlights

  • Achieve ideal results more quickly:

    Constant power when sawing to 85 mm thanks to the high-torque 2300-watt motor with power electronics.

  • Convenient and safe:

    Safe handling – thanks to cutting depth adjustment with plunge-cut function, remote control of the suspended cover, guide wedge and angle adjustment from 0 to 60°.

  • Systems get it done:

    Reproducible angle cuts and guided cuts with the cross cutting guide rail and the guide rail and groove routing with the adjustable groove cutter.

Product details

  • From portable circular saw to groove router

    With the adjustable groove cutter conversion kit, the versatile HK 85 becomes a groove router for transverse and longitudinal grooves, making it a real all-rounder. For grooves with a width of 16 mm to 25 mm and a depth of 35 mm.

  • The quick-acting closure

    Coupling the HKC 55, HK 55 and HK 85 with the FSK cross cutting guide rail, which is available in three lengths, is incredibly easy. In no time at all, you have a mobile, easy-to-handle compound mitre saw system for precise and accurately angled cuts.

  • Stop system

    The fixed positioning bolt and the adjustable stop allow angled cuts from –60° to +60° to be made and repeated exactly. For simple work, the most common angle settings are locked into place in the rail.

  • The retraction function

    To ensure that it is always ready for use, the cross cutting guide rail has an adjustable stop and an integrated rubber spring, which automatically brings the HK 85 back to the starting position.

  • Pendulum hood remote control

    To enable a clear view of the saw blade, the pendulum guard can be moved backwards from the front handle. This uncovers the saw blade and ensures your hands always remain at a safe distance from the saw blade.

  • Guide wedge for a high level of safety

    The guide wedge enables unobstructed, stress-free and therefore safe sawing. As it is integrated into the spring-mounted pendulum hood, it is also possible to carry out plunge cuts in a safe and unobstructed way.

  • Viewing window and gauge marker

    The open construction and the viewing window on the inside provide a good view of the scribe mark and saw blade. The continuous gauge marker also increases precision.

  • Extremely easy depth adjustment

    Simply push the lever and set the desired cutting depth using the clearly visible and easy-to-read scale, then release – and you're done. When combined with the plunge cut function, you can also make plunge cuts to the preset cutting depth easily and conveniently.

  • The FastFix saw blade change

    Quick, one-handed and with no need for tools. Saves time and improves quality, because working with a material-specific saw blade goes without saying.

  • Scribe mark = cut

    Precision work even for mitre cuts of up to 50° (HKC 55, HK 55) and 60° (HK 85). When sawing in combination with the guide or cross cutting guide rail, the scribe line will always follow the cutting edge exactly, even when mitre cutting.

  • Precision guidance

    The HK 85 demonstrates its versatility when combined with the Festool guide rail system, too.

Main applications

  • Rip and cross cuts in materials up to 85 mm thick
  • Wide application range for mitre cuts up to 60°
  • Cutting tenons, square timber and boards
  • Cutting panel materials, wood fibre insulating materials and sandwich panels

Performance features


    Integrated bayonet fitting as the connecting element between the extractor and the tool.

  • MMC Multi Material Control electronics

    “Multi Material Control” power electronics with constant adjustable speed and temperature monitor for work on all types of material.

  • Cross cutting guide rails

    Compound mitre saw system which securely joins machine and cross cutting guide rails together for precisely accurate repeat cuts.

  • Antistatic function

    Mobile dust extractors and tools with the antistatic function to prevent static charge from accumulating when working.

  • Quick-acting brake

    For safe work when planing, sawing and routing.

  • FastFix

    Makes changing routing, sawing, planing, sanding, drilling and screwdriving tools easier.
