Rotary tool Proxxon MICROMOT 230/E — 80 W, 6,500–21,500 OPM, AC 220–240 V, 270 g

Proxxon MICROMOT 230/E is a compact, AC-powered rotary tool designed for precision work including drilling, milling, grinding, polishing, brushing, cutting and engraving. The unit runs on 220–240 V with an 80 W input and offers a continuously adjustable idle speed from 6,500 to 21,500 oscillations per minute (OPM), delivering nearly constant torque across the speed range. The slim glass-fibre reinforced polyamide housing with a soft component grip allows comfortable pen-style handling for fine tasks. The tool is lightweight (270 g) and includes high-quality steel collets for accurate clamping of small shafts.

Advantages

The MICROMOT 230/E combines a balanced, low-noise DC motor with long service life and full-wave electronic speed control for smooth, vibration-free operation. Ground, ball-bearing spindle construction and precision steel collets reduce runout and prevent rattling of bits and cutters. A spindle lock button enables quick tool exchange, and the 20 mm collar makes the unit compatible with MICROMOT drill stands and horizontal stands. Included collet sizes support a wide range of accessory shank diameters for immediate use.

Suitable for

• Hobby model making and scale modelling
• Jewellery making and fine metalwork
• Micro drilling, engraving and intricate cutting tasks
• Small workshop tasks requiring controlled polishing, grinding or brushing
• Work with small-diameter bits and mandrels

How to use

Fit the appropriate collet for the accessory shank and secure the accessory by tightening the collet; use the spindle lock button to hold the spindle during exchange. Connect the tool to a 220–240 V AC supply and set the desired idle speed with the control; reduce speed for micro drilling, brushing or polishing to maintain control and torque. Hold the tool in a pen grip for fine work or use the 20 mm collar to mount the unit in a compatible drill stand for repetitive or precision operations. Allow the tool to reach the set speed before engaging the workpiece and apply light, steady pressure.

Usage recommendations

Use cutting, grinding and polishing accessories rated for the MICROMOT speed range and ensure collets tightly fit accessory shanks to avoid runout. For delicate materials, operate at lower speeds and use minimal pressure. When performing extended work sessions, monitor the tool for heating and allow cooling intervals; follow safety practices such as eye protection and dust extraction appropriate to the task.
