The SPM301’s mechanical linkage allows the pilot drill and router bit to cut at the same time, reducing cycle time without sacrificing cut quality. Simple back fence, stop rail, and depth adjustment make setups and adjustments quick and easy. The built-in analog depth gauge allows changing material thickness a breeze and can be completed within seconds. When it comes to manufacturing, the SPM301 is unmatched. Manufactured completely in the USA, the SPM301 showcases heavy duty construction; a machine truly built to be a work horse and requires only standard 110 VAC and 1-2 CFM compressed air at 80 PSI.
