The MAFELL KSS 40 18M bl PURE 18V Cordless Cross-Cutting System (Ref. 91D524) combines precision rail-guided sawing with portable cordless operation for interior finishing, flooring, framing, and trim work. Driven by a compact brushless motor, this system executes cross cuts, rip cuts, miter cuts up to 45 degrees, compound miter cuts, plunge cuts, and shadow gap cuts down to 13 mm (1/2 in.). Supplied as a PURE bare tool in a T-MAX carrying case, it operates on the 18V Cordless Alliance System (CAS) battery platform.

A quick-release catch allows the saw to be detached instantly from the guided cross-cut rail, transforming it into a standalone portable circular saw. The rail system features a fixed stop and an adjustable stop with clear scale markings for fast, repeatable angle cuts from +45 degrees to -60 degrees. With a 40 mm (1-9/16 in.) cutting depth on the track, the tool handles common interior assembly, parquet, laminate, solid wood, doors, and sheet materials on site without setting up a stationary saw.
