• Powerful 18 V technology.
• The rail is attached to the portable circular saw by a quick-release catch.
• Precise angle and miter cuts.

We have not reinvented cross-cutting – but we have made it easier and more portable. And with the new KSS 40 18M bl, we have even added a battery: one that delivers what it promises - innovative battery technology for maximum performance.

When it comes to internal finishing work, there is no better helper than the KSS 40 18M bl, whatever the task in hand: be it for floors, walls, doors, furniture, ceilings or roof battens – to make cross or rip cuts, rail-guided cuts, miter or compound miter cuts at angles up to 45°, or even plunge cuts.

Backed by 25 years of experience, it takes cross-cutting system technology to the next development level with the addition of state-of-the-art battery technology.


One system, five, saws, one case: the KSS 40 18M bl can be used as a cross-cut saw, plunge-cut saw, shadow gap saw or portable circular saw with or without the Flexi-Guide for extra guidance when cutting.

Fastening the portable circular saw to the KSS rail creates a very practical single-handed cross-cutting system.

In combination with the roll-up Flexi-Guide, precise guided cuts up to a length of 1.4m can be executed....with consummate ease.

Perfect edging: the circular saw's spacers enable you easily to make exact expansion joint cuts with widths from 13mm.
