Makita Genuine 345238-3 Base Plate 4340 / SMA400 for Makita BJV140 Cordless Circular Saw

The Makita 345238-3 is a genuine OEM base plate designed to restore accurate, stable cutting performance to compatible Makita jigsaws, including the BJV140 and BJV180.

This flat metal foot — sometimes referenced under the part numbers 4340 and SMA400 — forms the foundation of the jigsaw's cutting action, supporting the tool against the workpiece and keeping the blade square to the cut. Constructed from hard-wearing metal with a protective finish, it is built to withstand the demands of regular trade use on site and in the workshop.

A worn, bent, or damaged base plate is a common cause of inaccurate cuts, increased vibration, and surface tear-out. Fitting a direct OEM replacement restores the tool's original geometry, ensuring reliable alignment whether cutting straight or at a bevel angle. The smooth underside allows the saw to glide cleanly over sheet materials without marking finished surfaces.

Compatible with the jigsaw's built-in bevel mechanism, this part maintains precise angular alignment across a range of cut settings. It is straightforward to fit using standard hand tools, making it a practical repair option for both professional contractors and competent DIYers looking to extend the working life of their Makita jigsaw.
