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).

Low voltage for optimal safety, 12V DC, max 40W input. ## Features - Portable - Compact ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B000S5KO3K | | Best Sellers Rank | #230,877 in Industrial & Scientific (See Top 100 in Industrial & Scientific) #9,722 in Industrial Power Tools | | Brand Name | PROXXON | | Colour | Green | | Customer Reviews | 4.6 4.6 out of 5 stars (720) 4.6 out of 5 stars | | Global Trade Identification Number | 04006274285125 | | Included Components | bare-tool | | Item Dimensions | 29 x 16.5 x 4 Centimeters | | Item Weight | 0.79 Pounds | | Manufacturer | Proxxon | | Manufacturer Part Number | 28512 | | Maximum Rotational Speed | 20000 RPM | | Minimum Speed | 5000 RPM | | Model Number | 28512 | | Number Of Batteries | 1 Unknown batteries required. | | Number Of Items | 1 | | Other Special Features Of The Product | Compact, Portable | | Power Source | Corded | | Recommended Uses For Product | Cutting, Engraving, Grinding, Polishing | | Style Name | 12-volt | | Upc | 785533786873 | | Voltage | 12 Volts | ## Product Details - **Brand:** PROXXON - **Voltage:** 12 Volts - **Power Source:** Corded - **Recommended Uses For Product:** Engraving, Cutting, Grinding, Polishing - **Colour:** Green ## Images ![Proxxon 28512 12-Volt Micromot 50 EF Rotary Tool - Image 1](https://m.media-amazon.com/images/I/513qJQiMU6S.jpg) ![Proxxon 28512 12-Volt Micromot 50 EF Rotary Tool - Image 2](https://m.media-amazon.com/images/I/31gZcvzW1FS.jpg) ![Proxxon 28512 12-Volt Micromot 50 EF Rotary Tool - Image 3](https://m.media-amazon.com/images/I/31PAuUmHMnS.jpg) ![Proxxon 28512 12-Volt Micromot 50 EF Rotary Tool - Image 4](https://m.media-amazon.com/images/I/61P8xHyZ2JS.jpg) ![Proxxon 28512 12-Volt Micromot 50 EF Rotary Tool - Image 5](https://m.media-amazon.com/images/I/51Rsx6VepAL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excelente herramienta! *by on Reviewed in Mexico 31 December 2022* Excelente maquina para modelista! Silenciosa ,muy buenos materiales, el mandril te permite diferentes medidas,muy recomendable , llego antes de lo eaperado! Seguiremos comprando productos proxxon! ### ⭐⭐⭐⭐⭐ Very impressed with the tool (Micromot 60 EF 12V) *by on Reviewed in the United Kingdom 21 August 2019* Comfortable to grip and use for extended periods - tested it on wood carving, rock cutting/engraving and glass etching - found it to be very controllable and easy to use. It's also quieter than I was expecting - which is another plus. Does require the Proxxon Power Transformer which must be purchased separately - would also recommend purchasing the Proxxon Footswitch as it makes operating it a lot safer. ### ⭐⭐⭐⭐⭐ Great little Tool! *by on Reviewed in the United States 29 October 2015* This little tool has a sweet feel and great balance!! It also runs true. It is the third in a line of attempts to get another tool to take some of the load of my Foredom tookl, and from having to do all of my work on my primary heavier duty Foredom cable tool. I bought a cordless model at Harbor Freight that came with only one battery. And the battery lasted all of about 15 minutes on a charge! Ridiculous! Then I was considering a cordless "Dremmel Micro". It looked like a nice tool, but it is a rechargeable stand tool, and it only comes with one battery. And coming out of the box with just one battery was unacceptable to me, for a tool that costs nearly 100 dollars by the time you pay the taxes on it. What was Dremmel thinking?So I tried a Dremmel model 2100 that costs around 65 dollars, 71 dollars + some change after taxes..And when I got home and chucked up a tool.and started trying it out, it did not run true, or even close to it. There was so much end wobble that my1/64th burr became at least a 1/32nd one while it was running. And I have seen this very sane complaint about Dremmel allot lately. How can Dremmel allow such poor quality tools to be put out on the shelves?Anyway, I had previous experience with Proxxon, and I loved my old Proxxon A/C tool. But sadly, I tried to use it in a situation where I really should have been using at least a small side grinder, and in so doing, I burned a resistor out in it. Now I am looking forward to using this new DC Proxxon version. Anyone who compares the feel and the much smaller grip area and the relative lightness of this tool compared to most of these other brands type tools will probably be spoiled to this Proxxon tool from now on! ## Frequently Bought Together - PROXXON Rotary Tool MICROMOT 60/EF, 28512 , Green - PROXXON 38704 MICROMOT AC Adapter NG 5/E - Proxxon 28594 Pen Sander PS 13, 12 Volt --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/334793030-proxxon-28512-12-volt-micromot-50-ef-rotary-tool](https://www.desertcart.us/products/334793030-proxxon-28512-12-volt-micromot-50-ef-rotary-tool) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-23*
