This is one of my favorite power tools and that was one of the reasons we did a power tool review on the Milwaukee Sawzall.  I truly love everything about this and can not find one item to complain about.  The Milwaukee Sawzall is a power tool used to destroy, so it is even more important to buy a good quality tool as more accidents happen during tear down.  The body is put through more stress during tear downs, which can cause fatigue quickly without the right tool! 

First impression when picking up the Milwaukee Sawzall power tool is “Solid”.  It has some good weight to it, but not to much, (8.9lbs) which helps in this type of application.  The rubber grips feel nice in your hands which means your hands will stay in place and not slide around.  The variable speed control is on the lower part of the “D” handle which is nice because your not going to accidentally change speeds.  Another item we noticed from the start was the balance of the tool.  The balance of this tool was perfect.  Some weight in the front that helps the tool cut, while the back was easy to move around.  The Quick-Lok feature is one of the best ideas to come along in a long time.  Since this tool is used to destroy, chances are you will ruin the power cord.  Instead of having to open the tool up to change the power cord, you can just disconnect it and put a new power cord on.  I don’t know how many cords I have ruined over the years, causing unnecessary down time for the tool. Not with this tool, just plug in a new cord and go.

We ran this tool through a number of tests, including, cutting 4×4, railroad ties, a lot of black pipe, plaster walls and more.  We tried to get the tool to bog down by wedging the tool blade, using an old blade, putting dust in the motor, and more.  We could not get this tool to stop or even bog down.  Yes, you can tell the difference between a sharp blade and dull blade, but that doesn’t have to do with the tool.  We thought we could get the tool to slow down with the railroad tie because it is wood covered in Creosote and has a steel s bar in the middle of the tie.  We did rip through a couple blades, but partly because we tried a wood blade for the metal because when you get to the middle of a tie, you are cutting metal and wood.  We ended up ripping through the center with a metal blade and a small amount of orbital action.  Another nice feature is you can adjust how much orbital action you want.  The collar that holds the blade is also an awesome feature.  With all we put this tool through, the blade never slipped out.  We even put the blade in a vice and used a pulley system to try and rip the blade out.  We ended up lifting the work bench up in the air.  So we had two guys sit on the table and still couldn’t get the blade to budge.  After all this when we did take the blade out, I thought it might be hard to get out, but nope, just a simple turn and it came right out like it was supposed to.  All in all we could not get this power tool to bog down.  We did rip through a lot of blades, but that’s about it.

After using the tool for a long time, our arms felt fine.  We were not fatigued due to balance or vibrations.  Again, this is one of the biggest keys to a tool of this type.

Over all, our power tool review of the Milwaukee Sawzall is EXCELLENT. We were extremely impressed with this power tool.  This is a must own for anyone who plans on buying a reciprocating saw.  There are a lot of other great manufacturers out there, but the Milwaukee Sawzall truly has very nice unique features.  

Pro’s – Where to start. I love everything about this tool. The Quick-Lok, the blade system, the balance, the feel.

Con’s – I really can not think of any negatives to this tool. If I want to get picky, I guess the only con I can find is they should include some more blades.

Professional Power Tool Guide Rating

We believe the value for this tool is incredible, one of the best values around. When you compare what this reciprocating saw has compared to the competition, this is hands down one of the best tools. Milwaukee’s unique Quick-Lok and blade lock make this tool even a better value compared to its competition.


The performance of the Milwaukee Sawzall is incredible. This is only an 11 amp tool, and more than enough power, I could only image the 13 amp. We tried to bind the tool to get the motor to stop and couldn’t do it. If you are not holding on tight, it will probably come out of your hand before you can get the motor to shut down.

Ease of Use

The Milwaukee Sawzall is extremely easy to use. The variable speed and orbital action are easy to reach and adjust. The blade lock is also easy to use and figure out. There are no tight parts that get stuck or need a lot of muscle to use.


The Milwaukee Sawzall has all the important features from slow to extremely fast variable speed action. The orbital is truly orbital, as opposed to some reciprocating saws that only orbital a little bit. The Milwaukee has enough action to make a difference for cutting wood.


This tool really takes two hands to use and has a very nice balance. There was no arm or body fatigue due to the tool. The workers front hand is perfect for holding the tool while the back hand is easily used for adjusting angles.


This is an extremely solid power tool. When you pick the tool up in your hands you can feel it right from the start. Cutting wood, metal or anything else, the low vibrations (Compared to other reciprocating saws) it a lot easier in on your hands.


This is a must own power tool for anyone. If you are a professional or home user, I wouldn’t consider any other reciprocating saw. The Milwaukee Sawzall is hands down the best reciprocating saw we have used. When this tool was designed they thought about everything from making the cord easy to change to the quick change blade system that truly locks the blade in place. I could go on and on about how much I love this power tool. If you all ready own it, you understand me. If you don’t own this tool, once you try it, you will see why I love it and used this as our first power tool review.




  1. This is really old now, but I have a favorite model an its the old 6537-22 Super Sawzall. These did not have an orbital action to them, those guys came on generation later, but the had both 25’ and 50’ (I have one: a 48-76-3050) quick lok cords. What I liked about these older models was their relatively compact size to the newer models, and the quick lock cords. I also like the cleat or foot these guys came with versus the foot on your favorite model because the do not get as gummed up by debris as the multi-tooh models, and are more easily cleaned out if they do. The new ones do not have the same “soul” as these guys do. I don’t know why Milwaukee abandoned quick lock cords for these tools, it leaves me shaking my head.
    Milwaukee also made a 48-76-2050 two wite quick lok cord too….. too bad these are no longer available.
