Customer Reviews for Milwaukee M12 12-Volt Lithium-Ion Cordless ProPEX Expansion Tool Kit with (2) 1.5Ah Batteries, (3) Expansion Heads and Hard Case

Its a little heavy, but it does an amazing job. Even a 1.5 battery has a great run time.

Very good and very useful tool also. I would recommend to anyone and everyone.

Kit didn’t come with the cutter as shown in the image.

It took a few times to understand the right way to the tool. Once I learned the neuances of a new medium its was quite easy.

Brilliantly useful for the intended purpose, these will rotate and expand using the milwaukee m12 expansion tool. Keep them properly lubricated and these will last. I have included a picture of the 3/4" head to see it in expanded form.

The tool to get if you are installing more than a few expansion pex fittings or need to do so in tight quarters. Like all Milwaukee tools this is solidly built and performs its function well. The manual alternatives are terribly impractical and as a certified hand therapist I can tell you they won't do your joints any favors. This not only expands but also rotates the expansion head which is something manual versions do not do and is necessary for proper installation. This fits into tight spaces which in plumbing is an inevitability. You can tell that 1" is about the max size fitting this is built for as it works pretty hard at that level, be sure to use the included lubricant and keep the second battery ready to rotate a fresh one in when the other runs out of juice. This will allow uninterrupted use. Expansion pex is superior if you care about maximum and uninhibited water flow.

I'm not a plumber , but this tool will make DIY a lot easier ..

PEX Expander works really well. Much faster and easier than trying to use the manual tool.

Works decent for the 1/2" however when doing 3/4" it struggles and sounds like it's dieing. Also unlike my Ridgid tools that the batteries give you consistent power till it dies, this you can feel and hear it struggles and almost stop once it gets to 1/2 charge left and need to swap batteries. Needs bigger batteries or be corded as option. Will be returning to purchase one with bigger batteries.

If you buy the Milwaukee M12, 2432-20 Expansion tool only, this expansion head is what you need for 1/2" PRO PEX tubing. It DOES NOT come with the tool as pictured with the Expantion tool & also mentioned in the Q&A on the HD website. Also, it does not come with grease that you NEED to use it. I could not find it on the HD website, so I will go to a plumbing supply house for it. I gather it's food grade grease, so make sure you get the right grease for this head.

Love this tool it comes with all you need to get to work . It expands 1/2 and 3/4 oponor all day with no issues . It does a good job with 1" but heats up a bit around the tenth back to back fitting . I love the size and weight of it and the light is really handy .

I own a lot of Milwaukee power tools and love them always durable and don't have issues with them. I purchased the Milwaukee M12 Pex expander and love it. I used a manual expander tool before and it takes time and results were not as exact as this tool. The Milwaukee rep at the store is awesome, super knowledgable he knows Milwaukee. The tool works great pull the trigger it expands and rotates automatically can't complain about that. It feels solid and works solid I don't feel like this tool will wear out, overall a great buy.

The expansion tool is made of high quality materials and should last, like most Milwaukee tools. Extremely simple to use and makes leak free connections every time without any guesswork. The tool is pretty pricey, but in my case, I'm re-plumbing my entire home, and it makes connections so simple, it was more than worth it.

Milwaukee has become as reliable as Skillsaw was back in the 70’s when I started lets hope they don’t sell out and become cheap imitations Master Carpenter/Builder Framing Square Const

Great tool! One you may not use every day if not a plumber by trade, but is a game changer when you need it. This tool along with the uponor water line system is by far the easiest, cleanest and fastest way to plumb. IMO

Great tool. Fast and gets the job done. I highly recommend

Great tool. Manual expanders do not meet pex worry from manufacturers even though they sell them and this one does.

It’s definitely worth the money. Cuts down on labor time and the compact design is great for getting into tight spots.
