Product Overview

The M18 FUEL SAWZALL Reciprocating Saw cuts faster than its corded counterparts and offers up to 2x more runtime and 5x longer tool life than competitive saws. The POWERSTATE brushless motor provides cutting power. Compatible with ONE-KEY, this is the industry’s first Reciprocating Saw that wirelessly connects to a smart phone to Customize, Track and Manage a tool’s performance and location. Unlimited Tool Customization allows you to connect to the tool and access predetermined set-ups for blades and materialsor have complete control over output speed and power for the specific application at hand. Once the desired output performance is reached, the custom profile is then saved to the memory of the tool and the connection to the smart phone is no longer necessary. The app will track all ONE-KEY compatible devices within 100 ft. range of your phone. By building the functionality into the tool, not the battery, all devices are trackable even if the battery is not charged or on the tool. The app will automatically keep records of the last time a tool was within range of the app, allowing you to pinpoint missing tools quicker and increase accountability of your crew. If you’re having trouble locating a lost tool, expand your search with the help of anybody with the ONE-KEY app. By opting in, when any phone with the app comes within 100 ft. of your tool, you will receive an updated location.

Customer Questions & Answers

Can you use any Milwaukee M18 Battery with this tool?

All my Milwaukee M18 Batteries are 2.0 amps.
Asked by: audiovideofreak
Yes, you can use any Milwaukee M18 battery with this saw, any also with any other tool in the M18 line. I use 4.0's in mine and get plenty of run-time. If you were needing to purchase batteries for use in this saw, I would certainly recommend those as a minimum, but your 2.0's will work fine, just obviously needing to be swapped out more often.

Customer Reviews

M18 FUEL 18-Volt Lithium-Ion Brushless Sawzall with One-Key 2 Bat Kit is rated 5.0 out of 5 by 6.
Rated 5 out of 5 by from All you need in a reciprocating saw and more! This is definitely an excellent Pro-Level cordless reciprocating saw. This is a Milwaukee sawzall set that comes with a sawzall, two M18 REDLITHIUM XC 5.0 batteries, charger, a 6 inch 10TPI metal blade all in a heavy duty case. The Milwaukee M18 Fuel Sawzall with One-Key is pretty heavy. With the battery it is almost 10 pounds. That being said it has a comfortable handle and average vibration while using it. It blade lock is a Quik-Lok spring loaded that is a little tough to use but works well. You pay much more for the One Key technology but it makes this a must for Pros that work with metal.

Rated 5 out of 5 by from Quality Sawzall Picked this sawzall to replace and older battery model. What a great saw. It is very hardy, well built and strong. It is a little heavy but felt well balanced in my hands. It is very powerful and with its variable speed it ramps up the cutting action very easily. I used it with new Milwaukee blades to demo cut 2x4s easily and cut some plumbing pipes. Later I attached a pruning saw and used it to trim trees. It easily cut 4 inch branches. It was like a hot knife through butter. The blades are easy to change and tooless. The battery lasts a looong time, I never personally ran out of power. It also comes in a very nice hard sided carry case that carries the tool, charger and 2 batteries (included)

Rated 5 out of 5 by from Powerful with smart features I’m a DIY home user and this Sawzall kit absolutely meets or exceeds my needs. It is very powerful, especially for a cordless. The kit includes a charger (which can charge both M12 and M18 Milwaukee batteries), two M18 batteries, the tool, and a blade in a custom case (see pictures). The tool has pushbutton variable speed with 5 settings. Quick blade change requires no tools. The adjustable boot is handy. Being an occasional DIY user, I haven’t used the One-Step feature which will save all the tool’s settings to a smart phone for easy recurring uses/settings; but I can see where a pro would find this extremely useful. The batteries have a charge indicator on them, another handy feature. The only downside to the tool is weight: the tool itself weighs 7 lb 7 oz, with battery it’s 9 lb—not a game changer, but something to consider depending on user. This is only my second Milwaukee cordless tool (I bought into a different brand in a big way years ago) and I’m very impressed with their tools. The kit is a bit pricey for an occasional user, but worth the price for a frequent user.

Rated 5 out of 5 by from TOP OF THE LINE This review is for the Milwaukee M18 FUEL Sawzall. This kit contains top of the line Milwaukee parts and so not to confuse its contents with other Milwaukee kits and parts here are the kit’s contents with their Milwaukee numbers: 1 - Sawzall #2720-20; 2 – XC5.0 batteries; 1 Multi-volt charger #48-59-1815; 1 – Blade #49-22-1135, 6 inch, 10TPI. All of these items fit perfectly in the big red Milwaukee case which in itself is a strong and rugged as its contents and perfect for transporting the tool to the job or project site. The inclusion of two XC5.0 batteries and the multi-charger make this kit a value buy. Of course the center piece of the kit is the new cordless Sawzall. The words that come to mind when using the saw for the first time are WOW and AWESOME. This saw has no equals – powerful and loaded with features. It can cut through almost any type of material without straining the motor of the operator’s back. The motor is of the brushless type so it runs quieter, longer, and heats up less than ordinary brush type motors. The batteries are the new XC5.0 having extended use time and more power than any other batteries. The batteries and the saw are in sync with each other so the output is regulated as to the type of work the saw is doing. Download the user manual from the internet to learn how to manage the built-in electronics and to experience the almost magically marriage of saw and electronics. The saw sports a one touch blade release lever that make changes blades as simple and quick task – no tool required. The adjustable shoe works just as the blade lease does – move the lever and the shoe locks in place. A simple but welcomed feature when using the saw in darkened areas is the LED built into the saw that lights up the cut area so the user can see the exact place to position the blade. While not considered heavy, the saw is definitely not light in weight – a small price to pay for all this power and quality. However, the user will appreciate its handling characteristics that rate high on the ergonomics scale. The included charger supports both the 12v and the 18v batteries so it can serve all the 12v Milwaukee tools that one owns or should own. For starters, I do recommend the purchase of the Milwaukee 12-piece blade kit, 49-22-1135, that includes an assortment of cutting blades for various materials and uses. This blade kit also includes a very hand and very useful carrying case for storing loose blades – no more scavenging the work place for that extra blade. Milwaukee tools cost a little more but a Milwaukee tool is more than worth that extra penny.

Rated 5 out of 5 by from Sawzall This is the most high tech sawzall that I have seen! I cannot believe the mobile app and the bells and whistles it has. The carrying case it great and it is well made. This brand has never let me down and I am sure it will get a lot of use so the feel and control of the saw is great! It is easy to use and has a ton of features. Can't wait to get more blades and do all kinds of projects!
