A range of electric screwdrivers, offering the highest levels of torque accuracy and repeatability, together with award-winning ergonomics, is now available from Townsend Coates. Operating at lower sound-levels, and consuming less power, than any other similar tools currently available, these high-performance devices are suitable for a wide range of light-duty, precision assembly applications (see Plate 8).

Incorporating more than a dozen innovative features, the VersaTec range of electric screwdrivers from Ingersoll-Rand provides a torque accuracy of ± 4.9 percent ­ more than twice as accurate as its nearest competitor ­ and operates at sound levels of only 69dB (at 30cm). Available in high- and low-torque versions, covering the range 0.03Nm-4.6Nm, the product features a unique egg-shaped textured grip, designed to fit almost any hand size, and able to maintain a nearly constant temperature for typical shift-length periods.

Available as a transformerless 230V version, or as a 34V version with controller, the high torque (0.06Nm-4.6Nm) VersaTec models can be supplied in straight, pistol-grip or angled configurations, while the 24V model is intended for tasks where low-torque (0.03Nm-1.2Nm) and speed control are required. The controller serves to activate special features, including soft-start, which allows for the accurate positioning of very small screws, and rundown speed, which provides application adjustment without changing tools.

By using a removable contoured flange, with a torque adjustment cover, the VersaTec solves the problem of unauthorised changes of torque setting, allowing only technicians with a special tool to reset torque from the exterior. A torque readout window provides instant confirmation of torque output, while brush wear and replacement are signalled by an external indicator light. Brushes can be easily replaced without opening the tool. Unlike competitive models, where it is necessary to cut and resolder wires, the VersaTec allows electronic repairs to be made quickly and easily by removing and unplugging the controller's quick connectors, and the device offers single-fastener access to its interior for fast and simple maintenance.

A wide range of accessories for the VersaTec includes a vacuum pickup adaptor, vacuum pickup sleeves, digital counter (optional), torque adjust wrench, extension cords, suspension bails, mounting brake and low-profile flange.
