The 50/EF with quick-action chuck. Practical for use with different shaft diameters. MICROMOT 50/EF Slim, easily handled and light. Quick-action chuck and electronic revolutions adjustment, with feedback effect (high engine power in the lower revolutions area). Special, balanced, low noise DC motor with high life expectancy. A transformer is required for operation. We recommend MICROMOT network devices from 1.0A. Technical data: Direct voltage 12 - 18V. Power absorption up to 40W. 5,000 - 20,000/min. Length 220mm. Weight 230g. NO 28 512 The MICROMOT 50/EF can also be used with MICROMOT steel clamping devices. This is recommended when milling continuously at high lateral pressure. This makes it impossible for the shafts to become loosened after prolonged working. Using clamping devices makes true running better than using the quickaction chuck. Note: The speed control of our 12 volt devices only works when operated via nonstabilised power supply units (e.g. all MICROMOT mains adapters). Connection to stabilised power supply units is possible. However, the devices will then operate with maximum rotational speeds (also applies to operation with batteries).
