The Mafell KSS 80Ec/370 Cross-Cutting System combines the cutting depth and motor capacity of a heavy-duty circular saw with an integrated 14-9/16 in. guide track for precise, portable cross-cutting and ripping on site or in timber framing applications.

Powered by a high-torque 17A CUprex motor with variable no-load speeds from 2,250 to 4,400 RPM, the system drives a 9-5/16 in. blade through thick timbers, tenon shoulders, and heavy framing materials. The saw mounts directly onto the included Guide Track 370, which features a non-slip friction base and an adjustable smart stop. Operators place the guide track edge against the workpiece and push the saw through to execute square or miter cuts up to 60 degrees without tracing lines or manually guiding the blade. An integrated rubber splinter guard on the track maintains clean, tear-out-free cuts along the top wood surface.

For standalone operation, the circular saw detaches from the cross-cutting track, expanding cutting depth up to 3-7/16 in. at 0 degrees off track. The saw is also compatible with the broader Mafell Guide Rail System for long straight rip cuts and sheet goods processing.
