As a remodeler, I rely on reciprocating saws nearly every day,
so when JLC contacted me about testing these versatile tools, I
jumped at the chance. Rather than try to compare every
professional-duty saw on the market, I narrowed the field to
the most powerful corded models from eight major manufacturers:
Bosch's RS20, DeWalt's DW311K, Hilti's WSR 1400-PE, Hitachi's
CR13VBY, Makita's JR3070CT, Milwaukee's 6523-21, Porter-Cable's
9748, and Ridgid's R3020.
All of these saws have orbital cutting action, and all but the
Milwaukee, Ridgid, and Hilti models have a conventional
D-shaped handle. The Milwaukee and Ridgid saws have rotating
rear handles, which make the tool more comfortable when you're
working in contorted positions; while useful, I didn't see this
feature as a must-have. The Hilti has an extended rear handle,
which is great for grasping with a gloved hand but makes the
tool 3 1/2 inches longer than any of the other saws.
Although all the saws feature toolless blade clamps, their
design and ease of use varied. My favorite clamp is Bosch's:
You just push in the blade until it clicks. A quarter-turn of
the release mechanism ejects the blade. The Bosch is the only
model that pushes the blade out automatically — a nice
feature when the blade is hot.
My second-favorite blade clamp is Makita's. It's similar to the
Bosch clamp, but with no auto-eject: You insert the blade until
it clicks and remove it with an eighth-turn of the tabbed
Hilti's blade clamp requires a quarter-turn for both release
and insertion. It was easier to use than several others but
wasn't a standout.
The Ridgid and Hitachi both have simple levers for inserting
and releasing the blade. The Ridgid lever is on the saw body;
it works pretty well, except that the blade sticks slightly if
you pull the release lever too far. The Hitachi lever is on the
blade clamp itself, and works fine, as levers go.
The hardest releases to operate are the knurled knobs on the
Porter-Cable, DeWalt, and Milwaukee saws. Each requires a
half-turn for insertion and a quarter-turn for release. But
even though they're a little hard to grasp, they're still an
improvement over the hex-key clamps of the past (see Figure
Figure 1. Bosch's blade clamp (top) is the
best of the bunch. You simply push the blade in until it
clicks. Rotating the metal collar a quarter-turn ejects the
blade automatically, reducing the risk of burning your fingers
on a hot blade. With no tab or lever, the round collars on the
Porter-Cable, DeWalt, and Milwaukee saws (bottom) were tough to
While not a huge problem, it's worth noting that the blade
releases on the Hitachi, Milwaukee, DeWalt, and Porter-Cable
saws aren't accessible when the blade is at the bottom of the
stroke. When it stops there, you have to push it back up or
bump the trigger to get at the clamp. I encountered a bigger
problem with the Milwaukee and Ridgid saws: The Lenox
demolition blades I prefer wouldn't lock in the clamps until I
filed the corners of the blade tang (Figure 2).
Figure 2. Lenox demolition blades —
the author's preference — won't fit in the blade clamps
on the Ridgid and Milwaukee saws until the corners where the
blade body meets the tang are filed. The process doesn't take
long, but it's an inconvenience.
The Makita, Hitachi, Milwaukee, and Hilti saws all have
vibration-dampening technology built into their drive trains. I
couldn't discern any difference between the vibration levels of
these four saws, but by the end of my first day of testing it
was easy to feel the difference between the saws with dampening
technology and those without it.
Based on my testing, it was obvious to me that the tools with
vibration control were less taxing to use. This can prevent
injury and increase productivity — especially if you use
the saw for several hours at a stretch.
Cases and Other Features
A sturdy, roomy case is a must. All of the saws come with a
storage case with room for extra blades. Makita's case is
metal, Ridgid's is a soft-sided bag, and the others are
plastic. With the exception of Ridgid's bag and Hilti's square
version, the cases were approximately the same size and shape
(Figure 3). Note that you have to remove the blade before
stowing the Hilti or Milwaukee saws.
Figure 3. With the exception of Ridgid's
bag and Hilti's square container, the cases are roughly the
same shape and size. All provide plenty of room for an
assortment of blades.
Though easy to overlook, the small LED headlights on the Bosch
saw are a nice feature; they really boost visibility in the
dark spaces where you're likely to use a recip saw. The Bosch
is also the only tool in the test with a rafter hook, which is
handy when you need to set the saw down within reach.
The Milwaukee model — the Super Sawzall — has a
quick-connect cord; Bosch has eliminated the cord altogether
and instead includes a male plug so you can run an extension
directly into the tool. The Ridgid saw includes a Velcro strap
for cord management and a plug that lights up when the tool is
The Hilti saw has two unique features, both extra options: a
D-shaped auxiliary handle and an aggressively toothed shoe.
While the auxiliary handle doesn't seem that useful, the
toothed shoe might be helpful during some types of
In addition to using the saws on all my projects for several
weeks, I did some more objective cutting tests.
For the first one, I nailed together a header from some
salvaged 2x10s. I included 1/2-inch OSB sheathing on one side
(Figure 4). I made six cuts with each saw — three in the
straight-cutting mode and three more in orbital mode —
and then averaged the times. I used a new 4-inch Lenox
demolition blade in each saw. In straight mode, the Milwaukee
came in first, with the Makita second (see specs chart,
previous page). In orbital mode, the Makita finished first, the
Figure 4. To simulate cutting out an old
window opening, the author made test cuts on a 2x10 header with
a 2x4 plate and plywood sheathing on one side.
To test metal cutting, I screwed 3/4-inch metal curb stakes to
a sawhorse and made a pair of cuts, one in each mode (Figure
5). In straight mode, the Milwaukee came in first, again
followed by the Makita. In orbital mode, the Makita finished
first, followed by the Porter-Cable.
Figure 5. To test metal cutting ability,
the author made cuts through a steel form pin in both standard
and orbital cutting modes.
I picked my favorites based on three factors: how well the saws
cut, their overall balance, and how easy it is to change
blades. The Makita is my top pick for its speed, balance,
comfort of use, and excellent blade clamp. If the company added
a spring assist to the clamp, like that on the Bosch, this
would be the perfect saw.
My next favorite was the Bosch; though slower than some saws,
it has great features like the LED headlamps, auto-ejecting
blade clamp, and rafter hook.
My third pick is the Hitachi: Its blade release works well,
it's well-balanced, and the anti-vibration feature keeps it
from jumping around a lot.
In general I liked the Milwaukee, too, but its blade release is
among the toughest to use. It needs tabs to grip or, better
yet, a clamp similar to Makita's and Bosch's. With a better
blade clamp, it would have been my second choice.
