Maximum precision for the perfect cut

The KS 120 is impressive with its precise cuts thanks to the twin-column guide, powerful cutting capacity of up to 120 mm and light weight of 21.5 kg.

Extra large dimensions with dual ball bearings

The Festool twin-column guide guarantees reliable, smooth guidance of the saw blade and represents maximum precision.

Quality down to the finest detail

A double laser line precisely marks the saw cut.

Robust and mobile for harsh construction site applications

Ribbing and high-quality cast magnesium increase rigidity while keeping weight to a minimum.

Impressive cutting capacity

The special cutting position of the KS 120 allows you to cut strip material up to 120 mm vertically against the stop or cut coving and cornices in their "original wall position".

MMC electronics for safe working adapted to the material

Variable speed preselection, smooth start-up, overload protection and also with integrated quick-acting brake.

Short set-up times, good results

Always optimally prepared with FastFix for simple and quick replacement of the saw blade.

Even greater comfort

Fine adjustment for setting the saw blade angle accurate to the millimetre. As with all important control elements, it can be adjusted quickly and conveniently from the front of the machine.

Unlimited mobility

With ergonomic hand grips for left-handed and right-handed users, cord holder, transport safety device, clamp and an extremely compact, lightweight design.

Saves time and eliminates errors

The bevel for rapid measurement of interior and exterior corners and subsequent simple and precise transfer to the saw.

Static and transport frame in one

The base frame turns the KAPEX into a mobile unit that can be converted into a sawing station in three hand movements. With a trimming length of 2.40 m (including trimming attachment).

Also for long workpieces

The extension table, which can be pulled out separately, provides reliable and accurate support for long workpieces as well.
