Sawzalls
When it came time
to decide what to write about this month, I started to
think about what tool is an incredibly popular tool, past
the obvious choice of cordless drills. The one I came up
with is the reciprocating saw. Now for people that are
familiar with this tool, you are probably saying to
yourself "it's called a sawzall." The truth is
the only company that manufacturers a "sawzall"
is Milwaukee, and the Sawzall name has become synonymous
with Milwaukee. Lets take a look at what a reciprocating
saw actually is.
Like the
Milwaukee name states, a sawzall will saw all. It can be
used to cut just about any material, including wood,
metal, fiberglass, particle board, PVC, tile, copper, and
just about any other material. The saw is straight, with
a back "D" handle design. The blade comes out
of the other end and the motion of the blade follows that
of a hand saw, which is an in line, or back and forth
motion. They come in either two speed, or the much more
popular variable speed models. The power that these saws
deliver varies drastically from manufacturer to
manufacturer, and many manufacturers offer several
different powered reciprocating saws within their line.
For the most part, the well built tools will be between 4
amps and 10 amps. Another useful feature to look for is
called orbital action. The best way to describe this is
that in addition to the blade going in and out, the blade
goes up and down as well, which makes the saw incredibly
aggressive when going through wood.
Up until
about two years ago the way you went about changing
blades is by inserting an allen key into a screw located
at the head of the unit, loosening it, inserting the
blade, and retightening the screw. The problems that
existed with this system were the overtightening and
stripping of the screws, lost screws, lost allen keys,
etc. Although their are still many reciprocating saws on
the market that use this system, the blade clamping
system has come a long way with the introduction of the
quick blade clamping system. Porter Cable introduced this
first, and several other companies including Bosch and
Milwaukee have followed suit with similar systems. The
way it works is you turn a knob, insert your blade, and
release the knob. Your blade is now locked into the
proper position. Dewalt just released a new system which
you simply pull a lever, insert your blade, and release
the lever. The advantage in this system is that you do
not have to touch the blade to remove it from the tool,
and if the blade gets hot, this can be an advantage.
A couple of
other things to look for: the manufacturers have gone to
new lengths to make these tools as vibration free as
possible, so run the tool prior to purchase to check and
see how much vibration it produces. The footplate should
bevel and adjust both in and out to set your depth of
cut. Milwaukee offers a feature called a removable quick
lock cord. The cord twists on and off, which is a
advantage if your cord goes bad. You don't need to take
the tool in for service. Simply twist off the existing
cord, and twist on a new one.
It's now
time for the Guru's best of the best. In the low price
category, I go with the Milwaukee model 6509-6. Variable speed, no frills, down and
dirty saw.
I
also love the new Dewalt DW309K. It is the highest amperage of all the
models, and the blade changing system is the latest and
greatest. The reason it did not get the overall nod is it
is brand new and has not yet stood the test of time. I
guess we will find out in the future.
