Milwaukee M12 Cordless Rotary Tool Review

The Milwaukee M12 Cordless Rotary Tool Receives A Brushless Motor Upgrade

Rotary tools have a long-standing history amongst serious hobbyists and DIYers for their versatility and precision. With advances in modern battery technology, many manufacturers are cutting the cord and taking a more Pro-focused approach. We’re doing a deep dive on the latest Milwaukee M12 Cordless Rotary Tool so you can decide if it’s a good fit for your tool arsenal.


Pros:

  • Brushless motor
  • Improved speed controls
  • Ergonomic grip
  • Lightweight design
  • Tool free collet

Cons:

  • No-Load Speed: 5000-27500 RPM
  • Collet: 1/8 in.
  • Motor: Brushless
  • Max Accessory Diameter: 2 in.

This brushless rotary tool has a total of 12 speed settings ranging from 5,000 RPMs all the way up to 27,500 RPMs. That kind of speed is right in line with what we expect from a pro-grade tool.

Setting the speed is easy, but there is a slight learning curve. To set the speed, just press the +/- to cycle through the settings. Each of the LEDs represents two speed settings. Odd speeds display initially as a solid light, while even speeds display initially as a blinking light and then go solid.

The 1/8-inch collet doesn’t stray too far from the norm, but there are some things to know before you get started. Although not included, Milwaukee’s collet is compatible with 1/32-inch, 1/16-inch, and 3/32-inch shanks. Additionally, the nose collar pulls double duty as a collet wrench, allowing for quick accessory changes.

So when is the best time to put this tool into action? Well, Milwaukee recommends this rotary tool for light sanding and grinding tasks, polishing, wire brushing, and even light cutting tasks. Its small, lightweight profile allows you to work with precision.
