## Overview

The Proxxon 28512 Micromot 50 EF is a compact, lightweight 12V rotary tool delivering variable speeds from 5,000 to 20,000 RPM. Designed ergonomically with a pen-style grip and vibration-free motor, it excels in precision tasks like engraving, milling, and polishing across diverse materials. Its efficient cooling system ensures extended use, making it the go-to tool for professionals and hobbyists demanding accuracy and comfort.

## Description

Perfect for milling, drilling, routing, polishing, cutting, cleaning, brushing, deburring, sawing, engraving, carving, etc. These lightweight high precision tool in a pen style design (diameter only 35mm (1.4")) is ergonomically formed to allow comfortable handling and optimal control. His quietness and effortless, vibration-free drive via the special permanent magnet motor, the ground spindle and collar bearing all contribute to the ergonomic design. An efficient cooling system facilitates extended use under various load conditions. Useable on any workable material e.g. steel, precious metals, wood, glass, ceramics, plastics, precious stones. Ideal for model builders, woodcarvers, jewelers, opticians, artists, dental technicians, tool and die makers, etc. Note: A mains adapter is required to operate the MICROMOT 60 devices. We recommend the PROXXON mains adapter NG 2/S. 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). Technical data: Speeds from 5,000 - 20,000rpm (no load), weight: 230g (1.2 lbs), length: 220mm (8 21/32"). Low voltage for optimal safety, 12V DC, max 40W input

## Questions & Answers

**Q: where is the on-off switch?**
A: The on-off is incorporated into the speed dial. Turn it and it clicks "on" and turn it further the speed will go up. Turn it the other direction and the speed will reduce and turned further will switch off.

**Q: Is there a replacement battery available and if so at what price?**
A: This model don't use any batteries. You must have a special adapter (also from Proxxon) from 220 or 120 V to 12 V.

**Q: Can I use a universal 12V adaptor or I have to buy Proxxon brand? Is any power supply included?**
A: I have not experimented with other power supplies, I can tell you the Proxxon power supply is 12 volt DC / 2 amp output.I can't tell you how much of that 2 amps the rotary tool uses under normal use. The label on my model 50E rotary tool states 18 volts DC max. and 40 watt power max.Other than being lighter and easier to handle for delicate work, a Dremel tool is what I use most of the time.

**Q: Is power supply is sold separately ?**
A: Yes, you will need to purchase a Proxxon power supply. Either a 38706 Proxxon NG 2/S or 38704 Proxxon NG 5/E. You must use a Proxxon brand power supply otherwise the speed control not work.
