Amazon.com Review
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. --Tim Block

From the Manufacturer
Orbital action has been added to the heavy duty 11 amp Super Sawzall for even more aggressive cutting applications in wood. The Orbital Action Selector lets you select the degree of orbital action, for faster cutting in thick materials. The Super Sawzall incorporates our patented gear protection system which absorbs the high impact caused by sudden blade lock-up, thereby extending the life of the tool even under the most extreme cutting conditions. Our patented Counter-Balance Mechanism makes the Super Sawzall the smoothest operating, most vibration free saw in the world. The Trigger Speed Control allows you to match the speed of the tool to the application. The new Heavy Duty Steel Quik-Lok Blade Clamp System enables you to change blades quickly and easily without needing a hex wrench.

The 6521-21 includes the Super Sawzall, 2 blades, and a plastic carrying case.

The Best Sawzall Ever Made!
I had a Makita for 13 years that wasn't too bad, but it finally died of bad bearings. The repair cost was within $10 of replacement so I started shopping.

I was going to get the 10 amp Super Sawzall, but after reading toolpig's review and considering the advantages of orbital action, I bought this one. It was only $5 more. I will never be sorry!

My first project was cutting up a bunch of rebar to use spiking railroad ties down. Over 100 cuts (with a Lenox blade) and I wasn't tired and neither was the saw. I slowed it down with the speed dial to keep from burning up my blade. I never realized how handy this one feature would be until I used it. You can get precicion control over top speed without having to finesse the trigger. Just set the max and pull it wide open - no more overspeed burns!

Next I was cutting railroad ties with a 12" Lenox blade. I started out in the straight cutting mode and it was slow after the first inch. I switched to orbital action and the blade just about fell through the wood! I was making straight cuts and miters on 8" x 10" ties with no problem. I had used a chian saw in the past, but railroad ties always have a "suprise rock" right in the path of your cut. The recip blades are basically disposable, so you can save the chainsaw for less risky duty.

This saw runs smooth and quiet, no user fatigue after hours of use. The adjustable shoe is real handy, another feature new to me after the Makita. If this tool lasts as well as it runs, you'll never need another recip saw. I don't see how they could come out with a better tool, unless it would run itself on voice command while you sat back and watched! Maybe next Millenium.

The only thing faster is a chainsaw
I just have to smile every time I use my Orbital Super Sawzall. It runs so smooth, I have to check to make sure it's plugged in.(not really but almost)It has the new METAL quick-loc blade clamp. A vast improvement over the original.As another reviewer already mentioned, there are more positions on the adjustable shoe. You get two varible speed controls. One on the trigger for careful cutting, and one on a speed dial for cutting different materials. If you run full speed on steel or other hard materials you will burn your blades up. With the 6521 you can dial it down to nothing if you want to. Basically it's a super sawzall on steroids. You get more power,plus the only infinitely variable orbital action I know of. Believe me, it works ! I have had orbital saws from other companies in the past. I sold all of them to make room for something better. I needed something that could be run continuously without dislodging my fillings, and making my hands numb. So I got the super sawzall.(Reviewed it in November) I love it. But sometimes I need more than one, like when I'm on multiple jobs. I thought about getting a cheapie but resisted the urge. Boy am I glad. The 6521-21 exceeded all my expectations. Obital action with no vibration. Plus they retained all the good features of the 6537. Including the impact protecting clutch,and a LIFETIME WARRANTY two things you won't get anywhere else. I highly recommend the 6521!

Best Sawzall I ever purchased
Everyone knows that sawzalls can cut through almost any material: wood, nail-embedded wood, plaster, metal, (steel, cast iron, aluminum, black pipe, conduit, etc.) drywall, plaster,... you get the idea. When I used this to cut through floorboards and 2x4's it was as smooth as a hot knife through butter. Unistrut and allthread were also no match for this machine. This 11 amp Super Sawzall has a standard blade stroke mode, plus an orbital stroke mode for a faster, more agressive cut through thicker wood. You can also adjust the amount of orbital action from none to full depending on the application. This sawzall also has the new Quik-Lok blade clamp with allows you to change blades in seconds rather than minutes. There's no more searching for a hex wrench to change blades here.

I've been using sawzall's for quite a while now and I have always admired Milwaukee Sawzalls for their dependability and durability. When I finally had to replace my old one and discovered that Milwaukee had introduced a new sawzall to their line, it was a simple choice for me. The added power and easy of use make this an idea choice if your building something new, tearing something down, or fabricating something for a job. I would highly recomend this product to anyone who wanted to purchase a sawzall.
