Professional Tool Reviews for Pros

Now, you might think choosing the best SawZall blade for any job would be incredibly easy. Just select bi-metal or carbide (among the various carbides). Then, decide how long the blade needs to be. Pick from 3, 5, 7, 10, 14, 18, or 24 TPI configurations. Decide whether to prioritize cutting metal (thick or thin), wood, nail-embedded wood, PVC, shingles, or even roots. Lastly, ponder how many blades it might take and buy enough so you don’t have to run back to the store. After all that, run the math to balance all those considerations so you stay within your budget.

Then again, perhaps selecting the best SawZall blade takes a bit more thought…That’s OK. We’ve got you covered.

Editor’s Note: SawZall is the Milwaukee trademark name for a reciprocating saw. Thus, when we speak of the best SawZall blades, we mean the best Milwaukee-branded reciprocating saw blades.

If the above options seem confusing—you’re in good company. Add to that, the fact that new SawZall blade choices appear quite often. In fact, Milwaukee Tool is in the midst of a carbide-tooth Sawzall blade expansion right now.

To help clear things up, we recently spoke with Karl Weber, Milwaukee Tool’s Sawzall Blades Product Manager, about blade selection. He broke down the key considerations, setting us on the path to blade choice mastery.

The foundation of blade selection centers around the material you intend to cut. The material determines the Teeth Per Inch (TPI) needed to cut efficiently. This also delivers the maximum blade life for that material. The rest of your blade selection choices should follow from TPI. Karl broke TPI down as follows:

From here, you end up choosing between two large categories of blades: bi-metal or carbide. Less expensive bi-metal blades offer satisfactory performance in common applications. These “disposable blades” work well when you can get the job done quickly and you don’t want to spend a lot on a blade that may not make it to the next job. You may, however, need to use several of these blades for tougher cuts.

Carbide tooth blades offer professionals more cutting options, improved efficiency, and potentially lower accessory costs. That last part may be hard to swallow without some math. After all, you’ve been to the store. Those carbide blades cost a LOT more than the equivalent bi-metal.

That math actually works out…

If you or someone on your crew has ever attempted a cut that burned up 15 or 20 bi-metal blades—that’s $30 to $40 (at least). It also translates into half an hour or more of lost labor time. That may be an extreme example, but you get the idea. In many cases, the right carbide blade saves time and money.

Clearly, Milwaukee Tool has a vested interest in promoting carbide SawZall blades. In our own experience—regardless of brand—carbide blades generally result in increased productivity.

Carbide blades also offer cut through more materials than bi-metal can handle. Take stainless steel for instance—don’t tackle that with bi-metal. When you combine faster cutting with significantly longer blade life, carbide starts to make a lot of sense. Why buy 3-5 blades, when one will do the job—and possibly the next job as well?

Milwaukee carbide blades have been available since 2016. However, in addition to original models, the lineup has introduced several new models. We expect the line to continue evolving over time.

We recommend one-handed reciprocating saws for pruning as they offer an easier way to cut low-hanging branches than chainsaws, pole saws, or hand saws. The Ax with Carbide Teeth for Pruning and Clean Wood blade perfects the accessory for this application with a durable solution for hardwood that clears material quickly and stays sharp. This 3 TPI blade practically devours wood as it cuts, making it our best SawZall blade for pruning.

The original Carbide Ax blade works really well for cutting through nail- or screw-embedded wood, shingles, plaster, or even Durock. This blade delivers a ton more life than any bi-metal blade—letting you cut longer before having to swap out for a new accessory. That alone makes it our pick for best SawZall blade for nail-embedded wood. Part of that arises from the use of a nail-guard design that keeps larger nails from getting in between the 5 TPI teeth and snapping off carbide bits. Instead, the blade glides over the nails and screws as it cuts.

The best carbide SawZall blade for demo work uses an agressive 6 TPI design. It lets you cut through a wide variety of materials. This blade not only tackles clean wood quickly—it can take on cast iron. Of course, that’s not our first choice for this blade, but in a pinch… This blade should be your go-to when doing demolition jobs that could reveal any number of materials needing to be cut away and removed. It even manages to keep the Milwaukee “Fang Tip” for plunge cuts into wood. The design stays close to the Ax design, but the increased TPI lets it transition into metal-cutting as needed.

The 7 TPI Carbide Torch blade is best for thick metal cutting applications. It offers a good balance of performance and value. This blade optimizes cutting performance for black pipe, cast iron, angle iron, and even stainless steel without being quite as expensive as blades dedicated to those extreme cutting applications (see the Nitrus Carbide blade below).

A truly unique and specialized solution, the Milwaukee Torch with Nitrus Carbide thick metal blade uses next-gen carbide teeth. It competes directly with other traditional carbide teeth reciprocating saw blades. The idea is to spend a bit more to maintain both accessory life and speed of cut. These 7 TPI blades last several times longer than Milwaukee’s existing carbide teeth reciprocating saw blades. They do it by reducing heat during cutting. The blades contain 25% more Nitrus Carbide per tooth, making them the best SawZall blade for cutting cast iron and soil pipe over and over again.

We’ve been asked how blade height and speed affect the cut. It presents a valid point since so many blades vary in height and thickness. Although these characteristics aren’t as important to blade selection as TPI and blade material choice, they do contribute to practical cutting speed.

Common 1-inch tall blades are more rigid and durable. Although shorter blades are more flexible for flush cuts, they don’t have the same stability. They also won’t last as long.

Regarding speed, you typically want to slow down when cutting thick metals and stainless steel. Heat is always the enemy of blade and tooth life. With that said, Milwaukee knows most folks simply pull the trigger and go…

Because of this, they test all of their blades at full throttle. It ensures an overzealous worker doesn’t necessarily burn up a blade faster than its stated life by going full tilt!

Once you’ve chosen the appropriate TPI and blade material, what blade length is appropriate? Karl explains that you should choose a blade at least three inches longer than the material’s diameter/width for wood blades. For cutting thick metal – especially pipe with an inner and outer wall, opt for a blade at least four inches longer than the diameter/width for safety. By the end of 2020, each of Milwaukee’s five carbide blades will be available in 6-, 9-, and 12-inch lengths.

In closing, choosing the best SawZall blade doesn’t have to be a mystery.

It might just save you loads of labor and money over time.
