Rated 4.7 out of 5 by 22 reviewers.
Rated 5.0 out of 5.0 by Very handy tool This tool has performed in my various home projects and has really impressed me. I’ve used it to cut hardwood, PVC, wire mold, card board, fiber glass etc. It’s conveniently sized. Battery power indicator and LED are really handy. Pressing the trigger is directly proportional to the speed and that’s how you control it. Changing blades work like plug-n-play and requires no tools. Keep in mind that this is TOOL ONLY; you still have to buy a battery for it unless you already have one. Battery will not come with the charger, so if you buy the battery then you have to buy the charger too. I would recommend buying Tool & Battery as a kit and save some money. February 21, 2013
Rated 4.0 out of 5.0 by Ez Twist Change Blade and Comfortable Grip Hackzall I've a hope chest of 3rd generation old tools. Receiving this modern version of a Reciprocating saw was a blast! I've spent hours looking for the right tool to put a blade on an old reciprocating saw. I'm having fun just using a couple of fingers to twist a knob with the Quik-Lok blade clamp. The grip is small enough for a woman, with rubber to make it easy to control. This isn't a tool I've used often. I've never had one I could grip and control. I'm looking forward to learning new things to do with it besides basic wood cutting. This Hackzall can be bought as an add on to the 12 Volt Red Lithium Ion Tools with Battery Kits, like the Brushless Drill. They come with an extra battery so both tools can be used in one project. Lastly, if you didn't notice in the specs, this has a 5, Five year warranty! February 28, 2013
Rated 5.0 out of 5.0 by Surprisingly Powerful Once again I'm blown away by the capability of Milwaukee's M12 line. This one-handed mini reciprocating saw provides amazing performance for its small form factor. It comes with two 4" blades: one for wood and one for metal. The vibrations are minimal when I have the guard pressed firmly against the material I'm cutting. The only times I experience excessive vibrations are when I don't have the material clamped or held down to a solid surface. So far the most challenging task I've thrown at the Hackzall was cutting down the holly bush in my front yard. That thing was the bane of my yardworking existence, and I finally got fed up with it. The two 4" diameter trunks took quite a while to cut through with a 9" pruning blade, but the Hackzall just kept on chugging. I completely drained a standard capacity M12 battery and got about halfway through the charge on a second by the time I was finished. I've got a total of four M12 batteries, and with multiple chargers I haven't had any projects that I had to pause and wait for them to charge back up. However, if you've only got one or two batteries, you may find yourself waiting during big projects with extended demand for a reciprocating saw. April 22, 2014
Rated 5.0 out of 5.0 by Genius This is one of the most handy tools any contractor or DIY'er can have. Cuts anything, cuts everything, gets in all the small places and has plenty of power to cut hardwood to drywall. I love it and pull it out more often then the Sawzall. Only fault is I wish it came with a rigid hard plastic case instead of a bag. But its a wonder otherwise. October 6, 2009
Rated 5.0 out of 5.0 by Great little saw I had an 18v saw all that was great for demo but as a home user didn't use too often due to its large size. I purchased an M12 drill kit and after playing with it at HD I gave it a go. Great little saw when on the ladder and up in the rafters. I feel more comfortable and confident with this small saw than my older 18v saw and the variety of blades makes this a versatile tool. My wife had a big grin once I purchased the pruning blade and this has become her go to tool outdoors. December 1, 2012
Rated 5.0 out of 5.0 by Nice Compact Saw This saw is about half the size of my 18v ni-cad saw but performs just as good. Because of it's size you can get into tight places that other saws won't fit into. One handed cuts are a breeze. Blade changes are quick and easy with a twist of the blade lock. The battery indicator is nice as you can do a quick check before going up the ladder to do a cut. Great addition to the tool box. February 12, 2013
Rated 5.0 out of 5.0 by Very compact and easiar to use! The new reciprocating sawzaw is absolutely the best. It can reach those hard to reach corners that the longer saw zaw just can not! Thank you fo rmaking an smaller better easiar reciprocating saw. April 14, 2015
Rated 5.0 out of 5.0 by M12 Hackzall The small but powerful package makes the saw very useful for getting into smaller spaces. The speed control is nice and smooth. Blade changes are easy and the blade lock works with just a twist. Plenty of power for cutting 2x4 boards. The battery indicator is a nice plus too. This saw is perfect for the occasional construction project and is a good addition to my workshop. February 14, 2013
