S Gear system

With our newly developed S-Gear gearbox, you can easily control the surface finish required by the job. With 5 different (preset) axial feed options, this unique gearbox system even allows you to adjust the cutting feed between preset positions when a different surface finish is required. The S-Gear gearbox also allows you to move the cutting tool in both directions, creating an in-and-out feed.
