The KAPEX Sliding Compound Mitre Saw is a true example of Festool's innovation. It's unique design allows maximum cutting capacity of the 10 inch saw blade, enabling you to cut 120 mm high skirting boards at their finished angle. Dual line laser beams clearly mark the exact width of the cut for positioning the work piece from the left or right. The variable width, expandable side fences provide secure and precise support even for long workpieces by increasing the surface area.  Fine adjustments give millimetre precision for angle and bevel cuts and the twin sliding rails ensure smooth guidance of the saw blade for the perfect cut. The compact design means no space is required behind the saw, allowing you to work easily in restricted spaces.

Main Applications

  • Cutting boards and panels up to 305 mm x 88 mm
  • Cutting crown moulding up to 168 mm at finished angle
  • Cutting framing timber and beams up to 88 mm thick
  • Cutting plastic and steel cable ducts
  • Cutting strip material to fit
  • Trimming aluminium and other non-ferous metal profiles
Special cutting position

Innovative design maximises the cutting capacity of the 10 inch saw blade so you can cut 120 mm high skirting boards, crown moulding at their finished angle. The smart bevel makes it easy to transfer angles from the wall directly to the saw.

Fine adjustments

The KAPEX cuts bevels up to 47 degrees on either side and mitres up to 50 degrees to the left and 60 degrees to the right. The convenient bevel lock and fine bevel adjustment feature make it easy to cut precise bevel angles.

Compact and mobile

Compact, lightweight design for easy transport and use in small areas, enhanced mobility with the mobile work stand.

Precise trenching

The dual line laser of the KAPEX marks the exact width of the cut so the work piece can be positioned from the left or right, simplifying the trenching process and providing perfect accuracy.

Fast blade changes

Change the blade to suit the material you are cutting with ease.

Tough for heavy duty work

Ribbing and high quality die cast magnesium provide a base with greater rigidity and less weight. Twin sliding rails with dual ball bearing mounting ensure smooth and reliable guidance of the saw blade.
