The Mafell K 105-18 PURE cordless portable circular saw is designed to meet the evolving demands of modern woodworking. It combines robust material and build quality with a carefully considered design focused on ease of use and ergonomic handling. Dual-battery technology supports consistent performance and flexible operation across a wide range of applications.
ErgoBalanceConcept and safety in the K 105-18 PURE Mafell Cordless Portable Circular Saw
The saw is built around the MAFELL ErgoBalanceConcept, which optimizes handling across different working positions. This supports precise control while reducing user fatigue, particularly during extended use or demanding cutting tasks. A key safety and convenience feature is the FLIPPKEIL system, which removes the need to unscrew the riving knife, improving safety and efficiency during plunge cuts.
Mafell K105-18 PURE Cordless Portable Circular Saw: versatile circular saw for diverse cutting applications
This model is suitable for cross-cutting and rip cuts, bevel and compound mitre cuts up to 60 degrees, birdsmouth cuts, plunge cuts, chamfers, and grooves. It is compatible with a broad range of materials including solid wood, board materials, insulating materials, doors, worktops, and interior finishing and renovation materials.
High-precision cutting performance with optimized visibility and control
Performance features include effective chip ejection, particularly when working with insulating materials, and bright LED lighting that improves visibility across the work area. The saw allows cutting directly to a mark, with a pointer that automatically adjusts to the selected tilt angle. It delivers a cutting depth of up to 110 millimetres, and up to 104 millimetres when used with a guide rail, while depth adjustment and locking can be completed in a single action. The redesigned tilting mechanism also improves scale readability, and the base plate groove enables use as a cross-cutting system when paired with the required guide device.
Guided versatility and cordless system compatibility from Mafell's K105-18 PURE Cordless Portable Circular Saw
For guided applications, it is well suited to cutting structural timber to length using guide L, supporting a maximum cutting depth of 104 millimetres and a cross-cutting length of up to 370 millimetres. Rip cuts can also be performed efficiently using a guide rail or parallel fence with full cutting depth capability. Powered by two CAS batteries, the system delivers strong performance and independence while remaining fully compatible within the Cordless Alliance System. This allows seamless use across a wide range of system partners, supporting flexible jobsite workflows.
