I use my cordless
jigsaws when the
reciprocating saw is just too cumbersome for those tight and
precise
cuts.
Cordless jigsaws
are lightweight and
easier to handle.
The vibration is very minimal and
the blades
that are normally used make much cleaner cuts.
It's
much easier to see your work which makes for a more accurate cut all
around.
Typically
you can make fairly tight scrolling cuts with ease
and your not limited to straight line cuts.
If
your work piece is to big to fit in the scroll saw then
this
is the power tool of choice.
My jigsaw tends to be one of the most used
power tools in my workshop or
on the project site.
Who
Makes
The Best Cordless
Jigsaw?
Once
again this is a matter of opinion and personal preference.
Most of the big
name manufacturers build a pretty decent power tool in
this category.
Some are listed below:
Dewalt
Craftsman
Bosch
Milwaukee
Makita
Hitachi
Ridgid
Ryobi
Skil
Black and Decker
Porter Cable
Plus many more...
Which
brand name you end up buying may depend on several
different factors.
Let's discuss those next.
What
to
Look for when Buying
Battery
Sizes
Like
any other cordless power tool your battery is going to play a big part
in which brand and model of jigsaw you choose.
The battery
sizes can vary from 14.4v all the way up to a
28v capacity.
Each will deliver the power and charge duration based on the voltage
and type of battery offered.
Whether it's a NiCad or Lithion-ion will determine the
duartion of charge and the speed at which you can recover a
charge.
Both
types have their pro's and con's and will perform
based on use, frankly either type works for me.
I've used both and have been satisfied.
Speed
and Control
Most
of the cordless jigsaws have a variable speed feature which is
controlled with the trigger.
More often than not you will not have a lock-on mechanism
that you may find on a lot of the corded jigsaws.
On the average cordless jigsaws will run between 500 and 3000
spm (strokes per minute).
The faster the stroke is the cleaner the cut you will have .
Don't forget that having the ability to slow your jigsaw down
occasionally can help you control your precise cutting as
well.
Quick
Blade Changing
This
feature has become commonplace in the power tool world today.
Having to find a screwdriver or special tool to change your jigsaw
blades is a thing of the past.
To me this is an
important feature on this type of cordless tool.
Now there are some tools with this feature that don't always work as
intended and can fail often.
For the most part this type of mechanism has
become pretty reliable in recent years.
Orbital
Action Capablitiy
Having
an adjustable orbital action is an additional feature that can be
useful.
High orbital action can help speed up your cut through a tougher or
thicker piece of material.
On the other side of the coin you don't want this feature set
on high if splintering of your material matters.
This can happen when
cutting
through a finish plywood laminate for example.
Typically you will have three to four different settings on a standard
jigsaw's orbital action and they will be
controlled with a lever or dial.
I do use this function on my cordless jigsaw alot.
Capacity
Most jigsaws can cut wood up to about two
inches thick, and others will
max out at around five inches.
Of course
this varies with blade size and length, but the amount of
power and the spm (strokes per minute) the jigsaw has will
make a difference on how well it handles thicker cuts.
You will find that blade bevel drifting may happen with a
thicker cut and a longer blade.
I tend to stay with 2 1/2 inch or less deep cuts if at all
possible....any more than that and I will use a different
power tool and method of cutting.
Jigsaw
Blades
Choosing
the right jigsaw blade can be just as important as the size
of your battery.
First
and foremost you need to have the correct type
of blade for the work you are doing.
Are you cutting metal or wood ?...obviously an important question.
What type of wood?.... Plywood, dimensional lumber or a finished piece
of window trim.
What type of metal?...aluminum or steel.
Just make sure your grab a decent set of of jigsaw blades that handle
all types of materials...and use them accordingly.
Our
Conclusion?
I use
this type of power tool just about as much as my cordless drills.
Lightweight and very portable it performs
well on just about any material and type of cut
I can
throw at it.
I always keep it handy for those special cuts that nothing else seems
to be able to handle...it seems I can't
function without it!
