With controller for speeds of 900 - 6,000rpm. The triple ball bearing armature provides direct drive (no gearing). This yields virtually vibration-free operation and extremely high spindle accuracy. Aluminium die-cast head with spindle neck of 43mm (European standard). Remainder of casing is fibreglass reinforced nylon. Large, easy to use switch with emergency function. Chart indicates optimum speeds for milling and drilling of various materials.Technical Data:Control unit with full wave electronics for 230V, 40VDC secondary voltage. Power consumption up to max. 250W. Spindle speed infinitely variable between 900 and 6,000rpm. Complete with triple slit, hardened collets covering 2.35, 3.0, 3.2, 4.0, 5.0 and 6.0mm, as well as spanners. Weight 4.2kg.N.B. The motor operates at 40V, supplied from the power pack/controller. At this level, the control characteristicsare ideal and yield high torque, even at lower speeds. (The compound table, drill stand and clamps are not included).
