Name: C.R. Onsrud Inverted Pin Routers — 500 VS / 750 SS / 900 VS / 900 VSX (a distinct class: hand-fed, spindle-below-table pin routers)
Brand: C.R. Onsrud

professional

These are C.R. Onsrud inverted pin routers, a fundamentally different class from the company's CNC machining centers: the cutting spindle sits below the table and the operator hand-feeds the workpiece over a guide pin/template for plunge routing and inside/outside profiling. The 500 VS is a light/intermittent-duty benchtop unit, the 750 SS a medium production-duty machine, and the award-winning 900 VS/VSX a continuous-duty machine for up to 3 shifts/day, with the VSX adding electronic variable speed. All handle wood, non-ferrous metals, aluminum, plastics, and composites up to 4" thick.
