For years, Milwaukee's Sawzalls have been valued for their outstanding ability to cut through almost any material: wood, nail-embedded wood, steel, cast iron, aluminum, brass, drywall, composition materials, hard rubber, cement, brick, plaster, and fiberglass. This 11 amp Super Sawzall has a standard blade stroke mode, plus an orbital stroke mode for more aggressive, faster cutting of thick wood. You can choose the level of orbital action, too, to fit the application--or you can switch it off for cutting in metal. Like almost all reciprocating saws, this Super Sawzall also has variable-speed control (with a speed control dial) for versatility, control, and increased efficiency over a wide range of applications. For those of you who've grown up with Sawzalls, you'll appreciate the addition of the handy Quik-Lok blade clamp, which lets you change blades quickly without having to use a hex wrench; this feature is especially convenient when you're cutting hard materials, such as steel, a situation in which blades break frequently. There's also a handy quick lever adjustment for the shoe.

We really like this tool's counterbalancing mechanism, which reduces some of the unavoidable vibration found in reciprocating saws. The difference you feel when operating this tool, compared to nonbalanced saws, is significant: the Super Sawzall is still extremely powerful, yet it has a smooth feel. As a result, of course, you can work longer with less fatigue than you can using other, unbalanced saws. Another significant feature is the clutch, which, by absorbing shock and impacts to the internal mechanics caused by sudden blade lockups (typically encountered during extreme use), minimizes time wasted tending to a damaged saw. Although this is a heavy tool, it does have an ergonomically designed rubber grip that provides a solid, comfortable hold.

From the Manufacturer
This powerful 11 amp Sawzall features a 1-1/4-inch orbital blade stroke that gives fast cutting in thick materials while the orbital action selector allows you to set the degree of orbital action. The steel Quik-Lok blade clamp system makes blade changes fast and easy with no hex key to lose or screws to strip. Absorbing high impact forces caused by sudden blade lockups, the gear protection system extends the life of the tool in even the most extreme cutting applications. The antivibration system makes it a smooth operator. Other features included a steel wobble plate mechanism for long life, a dial speed selector switch to match the correct speed to the application, and a shoe release lever that easily adjusts the shoe without the use of tools. Your Sawzall purchase includes a two-blade pack; an 8-foot, two-wire Quik-Lok cord; and carrying case.

Simply Outstanding, October 19, 2002
Reviewer: Scott Gaines from Bethpage, New York United States
I needed a recip saw for some remodeling/demolition work I am doing at home. I checked all of the other saws, read all the reviews and finally settled on the Milwaukee 6521. Why? Well, let's look at it.

First off, it has a no BS lifetime warranty. This means that if some little gear cracks inside, they will replace it. Of cours, if that same gear is just worn out, I pay. But since it's a Milwaukee gear replacement, now that new gear has the same warranty. Can't beat that.

Next, this has all the features you will ever, and I mean ever, need. The orbital action (more on that later), quick change blades, and quick change cord make this simply user friendly even if like me, you've never held a recip saw before in your life. The counterweight/kickback protection is a plus, you won't find that on other saws for this price. And Milwaukee includes an Ax blade and a metal cutting blade with the saw.

A word on the orbital action, which I didn't find out until I went to the website, is that you just won't see it in operation. According to the website, this orbital action is happening at 53 times each way per second, and that only when the blade is in contact with the material to be cut. So it's there, it's working, you just can't see it.

The plastic case has a blade storage compartment that seems to want to keep opening, but this is EXTREMELY minor. In fact, if it wasn't for that I would have titled this review "6 Stars or better".

In short, if you're thinking about a recip saw, don't drive yourself crazy with all kinds of research. Just go to the guys who invented the whole thing, and still do it better than anyone else and buy the saw. The first time you use it, you'll say what I did. "Geez (insert favorite exclamation there), I should've bought one of these years ago."

I wholeheartedly and without reservation reccomend this tool. Go ahead and buy it, you will not be sorry.

"Super" Sawzall, October 7, 2002
Reviewer: carlg137 from USA
This saw has gotten me out of more jams than any other tool I own--and I own a few. I can't believe the power and flexibility of this saw. The only trouble I have had is that the shoe adjustment lock/lever broke the first time I tried to adjust it. I got a new one from the local "tool shop" where I bought the saw, and now it's fine--probably a defect in the first one. I have cut galv. pipe, notched 2-2X door headers, and plunge cut laminate countertop. I am always finding something that I wouldn't have been able to do without it. Thanks Milwaukee!!

Excellent Tool, A Core Tool For Anyone's Collection., August 21, 2002
Reviewer: rob smith from USA
I bought the Milwaukee 6521-21 Sawzall for a home improvement project, and after using it wished I'd bought it years earlier. This tool cuts at 3200 strokes per minute and has orbital action. The motor is 11 amps. This tool came with a rugged plastic case which has steel clasps. The case appears to be very durable and won't rust, scratch or dent like a steel case. It also has a flip up storage compartment inside for extra blades. This is a nice touch because your extra saw blades won't rattle around and damage the quick lock power cord or scratch the tool. The tool itself was vey well built. The seams of the plastic and metal parts lined up perfectly, and the fit and finish were perfect. The appearance was flawless. Being 11 amp and having orbital action makes this saw a little heavy. It has a solid "heft" to it. Does it vibrate when turned on? No. I would describe the feeling as being more like a gentle pulsing sensation. Your hands won't go numb or tingle when using this saw. Milwaukee calls this saw "the smoothest in the world" and they are not lying. Blade changes are a snap. Just twist the collar, insert the blade, and release the collar. It takes about one second to change a blade. How does it cut? If you choose the right blade it will cut any material that exists. I used it to cut a duct vent hole in my roof with the supplied "axe" blade. After first drilling the four marked corners of my vent duct opening form inside the attic, so that once I got onto the roof I'd know where to make my cut, I cut through the shingles, tar paper, and 3/4" wood in about 7 seconds. The Sawzall cut so quickly and efficiently that I didn't have to apply any pressure to the saw. The weight of the tool itself created enough pressure to effortlessly slice through the roof. I was on and off that roof in less than 90 seconds. Boy, that part of the job was easy! I've also used the saw to cut steel tubing, cut up several ratty old chairs; which then fit in my dumpster, and trim a few dead branches off an evergreen tree. Like I mentioned earlier, with the right blade selection, this saw will efficiently and smoothly cut through any material. Remember to turn off the orbital action when cutting steel - otherwise you'll trash your blade rather quickly. My only complaint about this tool is that the orbital action slide lever on top of the tool housing is very stiff to operate. But that probably prevents it from moving around while you're cutting. I highly recommend this tool to anyone who does home improvements, works with steel, or who is a contractor. With a Sawzall, circular saw, drill, and jig saw you can create anything. This is one of the "core" tools to own. Milwaukee's legendary reputation for building solid, high quality tools that work well is demonstrated in this recently purchased tool. I wouldn't consider any other brand of reciprocating saw.

Reviewer: jc21 from Earth
Milwaukee invented the Sawzall and they still make the best. Far smoother than the Tiger Saw, imho. Makes a real difference at the end of a long day of demo work.

top of the line and worth it, June 11, 2002
Reviewer: A home improvement enthusiast from Des Moines, Iowa
I shopped around for quite some time before I settled on 6521-21. I studied these machines and used several. All work OK, but I only wanted to buy and use one and this Milwaukee has lived up to their reputation. The counterbalance is super smooth. The orbital slide is a little stiff. The orbital action itself is for rough cutting but goes through material like butter. I really doubt that I can wear out this machine. Unless you are really brutal in your job, it will last. Skip the Milwaukee blades as they all seem pretty much the same... other brands are much more inexpensive. The metal case is great and very sturdy... a real plus.

Wowww..., June 6, 2002
Reviewer: jdm1974
I just got this beast two days ago and promptly put it to work removing a drop ceiling in my house followed by cutting down some tree limbs. It saved me hours of work over doing these tasks manually. The ease at which this tool goes through material is stunning. If you've never used this model before you are guaranteed after doing your first cut to pause for a moment and let out various joyous or amazed exclamations under your breath. I've used a Dewalt cordless before in demolition and that jiggered all over the place while cutting. The Milwaukee is so smooth you're tempted to think it isn't very powerful, no matter what the amps say, until you stand stunned after effortlessly slicing through your first mangled wood cut.

The quick-lok cord and the tool free blade change are so nice. Dialing in the amount of orbital action you want is wonderfully easy and extremely useful. So is the the variable speed. It definately helps to set the speed to the recommended setting according to what material you're going through.

As for durability, well it's a Milwaukee. Enough said there. Best warantee out there too.

Worth the money!, May 18, 2002

Ok, I,m cheap. I thought "This tool better perform for this kind of money." It has.... This tool was not a waste of money!

Whosoever pulleth this saw from the case shall rightful, March 21, 2002
Reviewer: Jamie Jamison from Seattle, Washington USA
King of England be. No kidding, I felt like King Arthur wielding Excalibur when I pulled this beauty out of her case and fired her up. The saw is built like every other Milwaukee tool, that is to say it's built like a tank, and as someone who used to command an M-1 Abrams and M60A3 I can say this with authority. There are two features on this saw that are brilliant, one is the Quik-Lok blade clamp, which makes swapping out blades incredibly quick and easy, no searching for that 3/16" inch allen key to unlock blades any more, just twist and pull. The other feature that I like is that the power cord is detachable and connects to the saw with a twist lock connector. This makes stowing the saw in the very nice red metal case very clean and easy and also means that if the cord gets munged on a jobsite that you can replace it without taking the tool apart. Sure, you could buy a cheaper reciprocating saw than this one, but doing so would be about as smart as deciding to save money by doing your own dental work at home with a can of spackle and a power drill. King Arthur had Excalibur, Roland had Durendal and you can have the Milwaukee Super Sawzall.

This is the saw!, February 22, 2002
Reviewer: A home improvement enthusiast from atlanta, georgia United States
Ok I just returned the Bosch I bought, What a mistake that was(read my review of that bosch recip). This Milwaukee is golden! padded METAL case, detachable cord, speed dial, its light and compact. The case holds the saw with the blade on. You can tell once you begin to open the outer shipping box that Milwaukee really cares about the product that leaves their doors. I know it wierd to talk about a tool this way but they really did their homework. Its just one of those simple pleasures, the right tool for the right job. Im a die-hard Bosch man, but this tool has made me question my position on blue tools. Thanks Milwaukee!

Best Sawzall Made, August 27, 2001
Reviewer: Al Spataro from Chicago, IL USA
I recently purchased this tool and am very pleased with the performance that it offers. Blade changes are very easy and fast due to the Milwaukee's patented chuck design (just turn the knob and pull out the blade), but be careful, if you have been cutting for a while that chuck will get very hot and it WILL burn your finger tips. I used this tool to cut through 1" diameter solid steel railings and it cut through like a hot knife through butter. This tool is far better engineered than it's competitors and the Milwaukee blades seem to hold up better also. Spend a few extra bucks on the Milwaukee and you won't regret it.
