The high-speed radial drilling machines of the KSR series are designed according to the machining principle “tool to workpiece” and are often used in maintenance and in tool and steel construction. The design offers unique flexibility and plenty of work space for larger workpieces, so that one side of the workpiece can be completely machined without repositioning. The machine frame offers clamping surfaces for clamping devices and workpieces on three sides. The quill feed can be varied in four stages by gearbox and with a manually mechanically adjustable depth stop.
