    • Powerful and Reliable Cordless Grinder for Precision Work
The Milwaukee 2939-20 18V Cordless 1/4" Braking Die Grinder is a fantastic tool that delivers on power and precision. As a professional, I rely on high-performance tools, and this die grinder does not disappoint. The braking feature is excellent for added control and safety during use, especially when working with intricate parts. The 18V battery provides solid power, and I love the fact that it’s cordless, which makes maneuvering much easier. It’s lightweight but still packs a punch, making it ideal for long working sessions. The slide switch is simple and easy to operate, and the chrome finish gives it a sleek, professional look. Overall, it’s a highly durable and reliable grinder that I would recommend to anyone in need of a quality tool for detailed grinding and polishing tasks. ... show more

    • Must for plumber,pipe fitter, pipelayers
As a pipelayer this tool is invaluable. Specifically used when cutting down roof drains or cutting existing pvc pipe that were stubbed too far into manholes. When you don't want to shovel 2' around a pipe to fit a Sawzall just hold this sucker down inside your pipe and cut it out clean and easy. I've never had an issue like some but we don't have weak wrists and forearms here. Never used it to cut D.I.P. or cast. Only PVC schd 40, sdr 35 and 26. Time saver. Highly suggest metal blades don't get the abrasive cutting wheels. Get diamond and metal ones they last sooooo much longer. You'll need to buy a Mandrel For Cut-Off Wheels W/3/8" Arbor Hole, 1/4" Stem to use this tool it does not come with one. And of course blades with a 3/8" hole usually 3" diameter for use. It's a must. Cheap tool saves you money on it's first few uses. Stay safe ditch diggers. ... show more

    • Good purchase. Good tool.
Its loud, its fast and has plenty of torque. It's the real deal... I dunno how they do it but they do. And that means I get to own one of these at a way more digestable price. I bought a 4 pack of tungsten or cobalt burr bits and went to go at it on round of lodgepole, and the first bit went fast and okay... But when it started getting deeper... It would grab like a muff rucka. And when it grabs like that, its hard to hangon and stay in the cut. This thing has a 20k rpm rating I think... And I don't think those bits were made for hogging out wood. So I just looked up random 1/4 shank grinder bits and found rasp bits for wood. Those are perfect for what I've wanted to do.... They don't grab and they grind through at a slower rate even though they're going at 20k rpm. Easy to control and is useful for detailing. Now I gotta figure out what them cobalt burr bits are for so I can see what they're all about... ... show more

    • Underperforming Die Grinder
The slide switch is awkward and hard to use, and the grinder lacks power for heavy-duty tasks. It also feels bulky and uncomfortable to handle.

    • Powerful and Affordable Die Grinder for Heavy Duty Work
I recently purchased the M18 die grinder for just $130, a steal considering its retail price of $270 on Milwaukee's website. As someone who works on heavy equipment, I understand the importance of having a reliable die grinder on hand. This tool has truly been a lifesaver on multiple occasions since I added it to my arsenal a few weeks ago. The performance of the M18 is top-notch, and the fact that it comes at such a discounted price makes it even more impressive. Even if you don't foresee needing a die grinder often, I highly recommend grabbing this one. It's a fantastic investment that I can't praise enough. ... show more

It works great. I wish I had known there was no speed control.
