Great power from a little saw
I bought this tool for cutting holes in OSB/siding as well as cutting conduit. The tool works exactly as expected and shines as a 12v tool. I was very surprised at what it was capable of and how quickly it cuts through a 2x4. This is not a replacement for a 18/20/corded by any means though but is a great addition to any tradesmans collection. The only con I have is that there is no hook or anything to hold it on my tool belt.

Get One
I use this tool almost every day, and with a 6.0 battery I can go all day with one charge. I am constantly recommending it to peers and other contractors when they ask “if I like it.” It’s definitely the little engine that could! With all the sales CPO offers, you get your money’s worth the first day you use it! I usually don’t write reviews, but for this tool, I feel obligated. Don’t hesitate, Get One!

Awesome!
This thing is awesome! Running a 6" sawzall blade it took forever to run the battery down. I own quite a few M12 and M18 Milwaukee tools and they never cease to amaze me with their power and runtime. This Hackzall is way more convenient than a sawzall for most stuff.

Milwaukee 2520-21XC M12 FUEL 12V Cordless Hackzall Reciprocating Saw Kit with XC Battery is a go-to tool for smaller tasks and more. I have used it to cut copper, aluminum, steel pipe, etc.; and I have used it for general around the home purposes. I have used good blades which this saw is very happy with. This saw has plenty of power and durability for a 12 Volt saw. It gets into tight places with ease. The shoe is not adjustable and does not pivot, but that has not been a problem since I adjust my cutting approach to fit the situation. I have used this saw "One Handed" style with ease. The Battery, a Lithium Ion Battery", does a lot of work before the need for a recharge. I also have it "Big Brother" the 18 Volt Fuel, and my wife and I use it a lot also for the bigger situations that require more power and provide a sufficient work space. Very easy to carry and store. I do recommend this saw, and its "Big Brother" (18 Volt Fuel, Brushless, with Lithium Ion Battery) for your "go-to" tool box... you will be surprised at how often you will reach for them. Remember to use the Appropriate, "GOOD QUALITY" Blades for the very best results and for the longevity of the equipment...

How much does the saw weigh? Is it the same size as the 18v version?
Giff on Feb 22, 2016
BEST ANSWER: It is pretty light weight it I think around 3lbs without the battery 4 with the 4.0hr extended battery. It's noticeably smaller than the m18 version. I also chose this one after reading nasty reviews of the m18 version and I've become a bit of a fuel brushless odor snob as the m18 does not have brushless. It about 11inches tool only and the motor housing is smaller for fitting in tighter spaces. This was not a replacement for big demo projects requiring a full size sawzall but it has very successfully cut through wood and screws as well as pvc and conduit.
I would highly recommend this if you have smaller cutting project or working in tighter spaces like between floor joists, studs, or under cabinets as its compact and easily controllable with one hand.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
