A special motor technology (no replacing of brushes necessary) with full-wave electronic speed control allows for powerful operation with constant torque, even at low speeds! This feature is especially important when micro-drilling, brushing and polishing on delicate materials (e.g. plastics, etc.). The extremely balanced motor, which makes the tool run smoothly and vibration-free, as well as low weight and the improved ergonomic design with the soft-grip two-component material allow for optimal control while working. The spindle runs in a precision ball bearing. A button locks the spindle for an easy exchange of bits. The keyless precision chuck allows for quick exchange of all accessories with shanks from Ø 1/64" to Ø 1/8" (0.3 - 3.2mm). The tool’s 4/5" (20mm) standard collar makes it fit easily into all other useful MICROMOT accessories, such as drill stands and vices, making this Precision Rotary Tool even more versatile.The heart of our MICROMOT precision tools for 115V: the direct current (DC) special motor.
