Questions & Answers

Please only comment if you can compare M12 vs M12 "fuel" vs M18, assuming each is using a 4 amp battery with a long life (not the 1. 5 amp). ?

What do you think they have in common? I only own gasoline-powered vehicles, so I have no opinion on non-gasoline vehicles. I do trim carpentry and keep my 12v driver, drill, and impact in my truck at all times. The 18v models would be in there if I did any heavier work. On both counts, the battery life is outstanding. Most days, one battery is enough for me, and I only use a second battery near the end of the day. These are fantastic instruments. I switched from earlier versions of the Dwalt 20v to these and haven't looked back. The yellow circ saw is a long way behind the 18v circ saws.

What is it like to cut galvanized pipes with it?

I've never used it on galvanized pipe, but depending on the blade I have in it, I wouldn't hesitate to do so.

Is there a source of light?

No, the saw does not have a light source.

FULL REVIEW OF THE M12 FUEL HackZall BY MILWAUKEE
5/5

While Milwaukee has named this tool the M12 HackZall, it's really a smaller, compact SawZall. br>br>Lightweight for use on a ladder and compact for tight spotsbr>br>Compact Weight and Sizebr>While Milwaukee has named this tool the M12 HackZall, it's really a smaller, compact SawZall. It's the ideal tool for getting into tight spaces where larger recip saws won't fit. It's only 13 1/4" long and weighs a little more than 4 pounds. Furthermore, the tool is well-balanced due to its design. The size-to-weight ratio is ideal for avoiding tool-fighting while in use. When one hand is required, the Milwaukee M12 FUEL HackZall can be used, but it can also be used with two hands. br>br>Accurate battery indicator lightbr>br>Battery Indicator Lightbr>I know we all got along fine before battery indicator lights, but what a better world we live in now. The lights on the M12 FUEL HackZall have proven to be extremely accurate, so I always know whether it's safe to go up the ladder or into a lift, or whether I need to change the batter before going up. br>br>Tool Protectionbr>Every day, tools become more intelligent, and the technology inside them improves, allowing you to use them for longer periods of time. If you put too much strain on the motor or battery in the M12 HackZall, the overload protection will shut it down. While this may be a pain in the short term for those of us who need to work on our patience, it saves time and money in the long run. br>br>LED Lightbr>I was pleasantly surprised by how well the tool's LED light functioned. Working in dim light and seeing the task in front of me was not a problem for me. br>br>Milwaukee M12 Tool Setbr>br>4. br>br>Milwaukee M12 Tool Set 0ah batterybr>As with any other Milwaukee M12 tool, you can swap out any of the four batteries. 0ah or 2. Batteries with a capacity of 0 ah In my opinion, the 4 is the best option. All of them work, even the 0ah battery with the flat base. The same batteries can be used with 60 different tools, whether they are FUEL or not. br>br>Overall Thoughtsbr>Over the last few years, I've become a huge fan of the red tools. And it's become one of my favorites as well. I don't believe this tool will let you down. Milwaukee invests a significant amount of time and money in research and development, as evidenced by the innovations it has developed in recent years. I've already used this tool on at least a dozen different projects around the studio, and I have no plans to stop using it. br>br>Complete Dissection- br>The M12 Hackzall is a 4-pound weapon. The M18 Hackzall weighs in at 5. 8 lbs (while carrying an XC battery pack). (With a small battery) 0 lbs. A pound may not seem like much, but if you're going to be holding the tool for an extended period of time, the weight difference will be noticeable. It's also crucial to know exactly where the weight is. On my M18 Hackzall (which I was wearing at the time), The motor protrudes well beyond the back of the tool (which I used extensively for this review). It improves the tool's top-of-the-line performance. When pitching it forward to cut, it has a heavy feel. That can actually help when you want the workpiece to have more weight to it—but I'll go into more detail about that later. The M12 Fuel Hackzall recip saw reduces the motor's depth by about one inch. Milwaukee also changed the angle of the handle (and, by extension, the entire tool) in relation to the battery by over 15 degrees. The M12 Fuel Hackzall model can now stand unassisted on its battery. That's a big deal for anyone who has ever needed to put one of these tools down for a brief period of time in a space with limited space (as I have). It's actually more ergonomic for cutting straight overhead because the tool considers the natural angle of your wrist to the cutting blade, rather than bringing everyone in line like the M18 model does now. br>Milwaukee also made significant improvements in the area around the reciprocating blade mechanism. The shoe and blade mechanism emerges from a square opening on the M18 Hackzall, as well as the brushed M12 Hackzall. Milwaukee closed the gap on the new M12 Hackzall (and, hopefully, the upcoming M18 Fuel Hackzall, which is almost certainly on the way), allowing only the shoe's twin steel posts to show through the plastic. The tool's front form a tight seal around the round blade mechanism now. Unlike previous tools, which allowed large amounts of dirt and debris to enter, the new tool does not collect debris within the tool itself, but instead allows it to fall off the front. Excellent engineering and design enhancements! br>br>Another significant improvement is that the Milwaukee M12 Brushless Hackzall has significantly less vibration than the M18 model, owing to its dual gear counter balance mechanism. It also has a strong impact. The reduction in vibration is considerable. As a result, more power is transferred to the workpiece rather than being wasted on vibration, which benefits the user. In practice, I found the tool to be far more enjoyable to use, even though cutting speeds on wood were nearly identical when the blade and tool did the work. The reduced vibration is actually a huge help in getting your cut started and finished cleanly on metal applications, such as cutting through conduit. br>Like the rest of the Hackzall tools, the blade fits into the Quik-Lock system quickly and easily. When you twist the Lok Blade Clamp, it never gets tangled or refuses to let go. This appears to be a very dependable and simple-to-use system. Milwaukee's blade system is a user-operated blade system that should last a long time. (If something isn't broken, don't fix it!) ) The M12 Fuel Hackzall has an integrated braking system in the blade mechanism. When you let go of the trigger, the blade comes to a near-instant stop, similar to the braking system on a circular saw. When the blade on my M18 Hackzall isn't engaged in any material, it takes nearly two seconds to wind down. br>I was fortunate enough to receive the Milwaukee 2520- I used the brushless M12 Hackzall to cut through some PVC for a small plumbing project (by "small," I mean we were re-piping a bathroom). 1500 sq. ft. of plumbing ft. a place to live ) From 1/2′′ PVC and CPVC to 3′′ schedule 40 PVC, we used it. I distributed it on the job site, and the response was overwhelmingly positive, with comments ranging from "Man, this tool is simple to use!" to "Wow, this tool is really cool!" " to "I had no idea Milwaukee had a 12V version" a saw with one hand " Everyone agreed that the M12 had significantly less vibration and was better suited to cutting on materials that moved (such as PVC installed beneath a raised home). " I was also impressed that, despite the fact that there were several options available, everyone present kept reaching for the tool as soon as it was introduced. br>The Milwaukee 2520- is a multi-purpose machine that can be used in a variety of applications.

We used a 6′′ Milwaukee Torch Double Duty blade for this job, which, despite being a little long (for this tool), did an excellent job cutting both copper and galvanized pipe, and provided another opportunity to appreciate the tool's reduced vibration during cutting. It's a feature that makes the tool more precise during cuts and allows you to use it for longer periods of time without becoming fatigued. br>I also ran some tests in wood with Milwaukee's Ax blades in a 6′′ configuration. These blades are one of my favorites. While I wouldn't recommend using the M12 Fuel Hackzall to demolish an entire house (or even a porch), it can be useful as a demonstration device in limited situations. It's not that the tool can't handle bigger tasks; it's just that it's designed for just that. work that is done by hand A long-term demo job will necessitate a two-person crew. a one-handed grip as well as a long run- Longer blades and additional tool weight help the tool do a lot more work, whereas the M12 makes the most of its light weight. br>br>Milwaukee Brushless Hackzall (Milwaukee Brushless Hackzall, Milwaukee Brushless Hackzall, Milwaukee Brushless Hackzall, Milwaukee Brushless Hack Stroke Length: br>Specificationsbr>Stroke Length: br>Specificationsbr br>SPM: 5/8′′br> 3,000 br>Battery: 3,000 br> M12 RedLithium XC4 is a lithium-ion battery with a diameter of 12 millimeters 0br>Charger: 0br>Charger: 0br>Charger: M12 Chargerbr>LED Lightbr>Quick-Charge M12 Chargerbr>LED Lightbr>Quick-Charge M12 Chargerbr>LED Light On-Blade Lok Universal Keyless Blade Clampbr>On-Blade Lok Universal Keyless Blade Clampbr>On-Blade Lok battery gauge toolbr>Length: 25′′br>Weight: 25′′br> 1 poundbr>Warranty on the tool: Battery Warranty: 5 yearsbr> 3 yearsbr>Conclusionbr>The Milwaukee brushless Hackzall is more than just a good tool or a good incremental upgrade. It outperforms both the M18 Hackzall and the current M12 model by a huge margin. This tool is also available in a package with several Milwaukee M12 drivers and tools for around $199 (with batteries) and $169 (without). If you've been waiting for a one-of-a-kind item, this is your chance. Milwaukee has eliminated all barriers to purchasing a right-hand reciprocating saw right now. The cordless M18 Fuel Hackzall is almost certainly on the way (though that's just a guess), but I believe the M18 will primarily serve as a run-around tool. If you're cutting PVC or small metal conduit, the Milwaukee brushless Hackzall 2520-S will save you time and possibly some extra torque. The 21XC kit will meet all of your requirements and is deserving of a spot in your growing toolkit.

Great job, Saw! It appeals to me
5/5

I work in the HVAC industry, and every now and then we need a saw that can cut metal, wood, and PVC. My friends all use full-size Dewalt sawzalls, which are great for their intended purpose but are two-handed monsters. The trigger on the Milwaukee Hackzall is extremely responsive and controls the motor with ease. I can start it at a slow speed and then increase the speed as needed for fine cuts. The saw is well balanced and easy to control as long as the blade guide is positioned against your work and the blade is allowed to do its job. The blades are securely attached to the saw, and I've had no problems with them coming loose. br>br>The best feature of the saw, and the reason I bought it, is its size. I needed to cut off a 2in PVC pipe that was hidden inside an air return cavity. Because I didn't have much room, I went to the van and got this saw. Like a knife through hot butter, the saw cut 2" PVC with ease. Not only did it cut well, but I also had no trouble controlling it. Have you ever tried cutting a motor shaft by hand with a hacksaw? This saw feels great in my hands, and everything about it screams quality. The bag that came with it is also well-made, and it, along with the saw, should last me for many years. Dewalt has always been a favorite of mine, and I have a number of their 20v tools. Without a doubt, I'm now a big fan of Milwaukee's 12v Fuel line and intend to buy some of their other products in the future. Finally, some thoughts: This is the ideal saw for getting out of a jam or cutting something in tight quarters. It comes with a fantastic blade lineup that can handle any situation. This is an amazing saw! It appeals to me.

Battery life and removal are both unacceptable
3/5

This tool's concept is fantastic. The tool excels at cutting dead limbs that are located far from an AC source. But. The battery life is extremely poor. If you work all day on a job, it's a good idea to invest in a second battery with a higher capacity than the one that came with it. Battery charging will be necessary on a regular basis. br>My main gripe is how difficult it is to remove the battery from the tool. To squeeze the little plastic pins that hold the battery in place, you'll need the hand strength of a weight lifter. The battery must be removed with a special tool provided by Milwaukee. Their current design gets a 0 out of 10 from me. In fact, because I get annoyed every time I have to remove the battery, this will be my last 12V Milwaukee tool. Design is a sham!.

Great saw, and a nice bag to go with it
5/5

Wow, what a fantastic tool! I'm currently working on three projects. I dismantled an old TV (plastic housing) that had been dumped in my alley, as well as cutting new slots in some stripped screws and wood. So far, it has performed admirably in every situation. I'm on my first battery charge right now. The saw, battery, and other items can all be stored in the bag. A charger and a slew of blades are included. There aren't any issues. TIPS: If you're really picky, take a picture of how the bag was packed before you take anything out. So you'll be able to figure out how to put everything back together. Not that you have to; the bag is large enough; however, some people prefer things to be exact. BTW: This bag is far superior to a large hard plastic case because it can hold more items, whereas the plastic case is only designed to hold the items that were included. Other than that, nothing. br>br>I'm also struck by how simple the insert is to use. blades should be changed My old saw was a Sears Craftsman Sabre Saw from the 1970s that belonged to my father. To keep the blade in place on the sabre saw, it requires a few small hex screws. Since then, man, have tools progressed tremendously! This Milwaukee Hackzall is so much better than the previous one that it's incredible. Following the purchase of the impact screw gun, I purchased this tool. They're a fantastic tool to have. But wait, there's more; The Milwaukee tools labeled "FUEL" are truly superior. Brushless motors are used in the "Fuel" line, resulting in motors that are more powerful and efficient without being larger.
