For drilling, milling, grinding, polishing, brushing, cutting, and engraving. The extremely slim housing, made of fiberglass-reinforced polyamide, features soft components in the grip area, allowing the device to be guided with two fingers in a pen grip. It has a balanced DC special motor that is quiet and extremely durable. The maximum speed can be continuously reduced by full wave electronics, maintaining almost the same torque in the lower speed range, which is particularly important for fine boring, brushing, and polishing. The ground, ball bearing spindle and high-quality micromot steel collets ensure that even the smallest shafts are clamped absolutely centrically, eliminating chattering and beating of the deployment tools. The spindle for tool change can be locked at the push of a button, and the system is compatible for use in micromot drilling rigs and horizontal rigs.
