The Mafell K 105-18 PURE 36V (2 x 18V) Cordless Circular Saw (Ref. 91D324) delivers impressive cutting capacity up to 4 5/16 in. (110 mm) for heavy-duty timber construction, framing, and insulation cutting. Powered by dual 18V CAS battery technology, this portable circular saw provides the mobility of cordless operation with the high power required for deep ripping, cross-cutting, and joinery cuts in solid wood, board materials, and composite insulation panels.

Built with Mafell's ErgoBalanceConcept, the K 105-18 is balanced for reduced fatigue and ergonomic control during demanding hand-held applications. For plunge cutting, the integrated FLIPPKEIL spring-mounted riving knife automatically retracts into the housing when plunging into workpieces and re-engages behind the blade without requiring manual unscrewing or removal. The tilting adjustment mechanism enables bevel cutting up to 60 degrees, while the cutting pointer automatically adjusts to match the set bevel angle to ensure precise cutting to the mark.

When used with Mafell F guide rail systems, the saw maintains an exceptional cutting depth of up to 4 1/8 in. (104 mm), making it suitable for long rip cuts and timber trimming. Integrated bright LEDs illuminate the working area, and an optimized chip ejection channel maintains clear sightlines and clean operation, especially when cutting thick fiber insulation materials.
