In-Depth Review: Milwaukee 2625-20 M18 18-Volt Hackzall Cordless One-Handed Reciprocating Saw


94 %

Manufactured by the company that made reciprocating saws a household name (ever heard of Sawzall?), the 2625-20 M18 Hackzall does not really need to prove much else. It delivers as much superior performance as it is small.

The purpose of this review is to get you acquainted with what makes the 2625-20 M18 Hackzall a good choice of compact recip saw. We hope this helps you decide on which saw to get for your shop.



Ease of Use


We Like

  • It is light, compact, and portable.
  • Variable speed allows for flexibility.
  • The LED light is a nice touch that helps a lot.
  • The anti-vibration system is a good feature.

We Don't Like

  • A little water can cause it to stall.


When we were starting out in remodeling, we often encountered big cutting jobs that we thought required the use of full-length reciprocating saws. A lot of it later turned out to be overkill, like shooting at an ant with a cannonball.

We realized this when we experienced using the 2625-20 M18 Hackzall. It is so powerful that although it is not recommended for heavy-duty work, it sure can take on cutting jobs of maybe upper moderate difficulty.

Since we started using this recip from Milwaukee, we did not feel the need to reach for our full-length recips as often as before.

Who Is It For?

The 2625-20 M18 Hackzall is for any handyman or professional contractor who works on a lot of projects that do not require heavy-duty cutting.

It is compact but comes with a variable speed of 0-3,000 spm with ¾-in strokes. For added ease of use, there is a Quik-Lok blade clamp, an LED, and a dual-gear anti-vibration system.

Although the 2625-20 M18 Hackzall’s features are more or less basic, it looks like Milwaukee got the balance right because the recip’s performance sets it apart from other compact saws.

We have used it to prune fruit trees, cut pipes, chop up large panels of reinforced steel, and more, and it is still working wonderfully today. Sometimes, we wonder if we are abusing it, but it looks like the 2625-20 M18 Hackzall was designed for that kind of tool owner.

Buyer's Guide

In case you are not familiar with the versatility of reciprocating saws, here are just some of the things you can do using them:

  • Cutting Metal

A recip saw can cut through metal sheets and thick steel pipes and posts. There are just some techniques you have to apply to make sure you do not end up damaging your saw or causing unintended cuts in your material.

When cutting metal, the lower the cutting speed and the more teeth your blade has, the better. Your recip will be safe from overheating this way.

If the sheet you are cutting is too thin, place it between two sheets of plywood and cut. That way, the sheet metal will not sustain tears caused by the aggressive cutting.

  • Cutting Frame and Studs

There are times you have to align studs with the floor during construction and renovation work. You can make a flush cut to trim excess material and get the studs to align correctly. You can also remove framing or studs by cutting through the nails beneath. If you do have to cut through studs, you can do so using a makeshift guide block for a nice cut.

  • Making Surface Cuts

Reciprocating saws do a great job of making plunge cuts. Instead of drilling a starter hole through the material, you can just tip the saw blade towards the surface and cut from there.

  • Cutting Drywall

Cutting through drywall is tricky because the material is thin and often have a lot of wires behind that you have to avoid. You can work around this by trimming your saw blade to match the drywall’s thickness. That way, you can cut freely without worrying about hitting wiring or studs beneath.

Features & Benefits

  • Cordless Design

The 2625-20 M18 Hackzall does not have a cord, giving it full maneuverability. You can cut in tight or narrow areas even at odd angles without the hindrance of a cord.

Another advantage to using a cordless recip like the 2625-20 M18 Hackzall is that you can use it even in remote areas without having to worry about power outlets, extension cords, and generators.

  • Anti-Vibration System

Vibration may not sound like a big deal, but it can make all the difference when you are already cutting. The 2625-20 M18 Hackzall has a dual-gear anti-vibration system that reduces the amount of vibration that gets transferred from the recip to your hand.

Less vibration means you get more stability, make precise cuts, and experience less stress or fatigue.

    Lightweight and Compact Design

Since the 2625-20 M18 Hackzall is small and light, storage should not be an issue. You can carry it on you or in a backpack and transport it anywhere without even noticing its weight.

  • Variable Speed Control

The 2625-20 M18 Hackzall has variable speed control, letting you adjust your cutting speed to match your material or to achieve your preferred cut. You can speed it up to make faster, more aggressive cuts or slow it down to cut denser materials without overheating the tool.

The speed control trigger is conveniently located under the handle where your index finger can easily press it. The trigger’s accessibility gives you direct speed control and lets you adjust without having to take your eyes off the blade.

Reviews & Testimonials

We went over the many reviews garnered by the 2625-20 M18 Hackzall to see how it served other users. Most (and we mean MOST!) of the reviews were so good that they ultimately pushed us to buy the 2625-20 M18 Hackzall.

We think that says a great deal about how great this recip saw is. Many of the customers comment on how versatile the saw is, being able to cut a huge variety of materials (including an entire car, in one customer’s case).

There were not a lot of complaints. There was negative feedback about battery and product life, warranty, and related matters but none of them was repeated, leading us to think that those may have been isolated issues.

There was a comment about how a little water in PVC piping caused the 2625-20 M18 Hackzall to stall. We do consider that a minus because as a saw used to cut pipes a lot, this product should be able to withstand a little water.

Overall, the 2625-20 M18 Hackzall appears to have won many power tool-loving hearts. It is a good match for anyone looking for a compact recip that does the job superbly.

The Final Cut

Before heading out to buy a full-length reciprocating saw, you first have to make sure that it can’t be done by the small but powerful 2625-20 M18 Hackzall.
