    Designed for high-efficiency operations, the BX.35 uses a 1.5 kW motor to drive a 9-speed (132–1852 rpm) hardened gear transmission. The electromagnetic clutch provides 3 selectable automatic feed rates (0.1 / 0.2 / 0.3 mm/rev). With a 150 mm spindle stroke and CM4 taper, it accommodates various tool setups. The cast iron frame, CE-compliant micro-switch safety guard, emergency stop, and low-voltage electrical control system make it a top-tier choice for industrial drilling lines demanding repeatable and safe performance.
