The Jigsaw is a versatile power tool for cutting almost unlimited shapes into various materials by simply selecting the right blade accessory and speed.
The saw blade which is positioned at a right angle to the motor shaft performs a straight or orbital stroke motion.
They come in 2 different handle configurations, D Handle and Barrel Grip . Though not common they are also available in cordless which is more typical of a professional application
What to look for when buying a jigsaw
Strokes/Min & Stroke Length
Though not as commonly referred to, the Stroke per minute and Stroke length ratings can be a very important factor to professional
Strokes/min (SPM)
The higher this value the faster the Jigsaw will cut through the material. A typical SPM rating would be 0 -3200spm
Stroke Length
This is the distance the blade travels from the minimum point to the full extension of the stroke. It is this distance and the length of the blade used that will provide the actual cutting depth. This length averages around 25mm
Pendulum or Orbital Action
This feature provides an oscillating action to move the blade in a slight circular motion as the blade moves forward on the upwards stroke. This is the same direction as the teeth cut in to provide a more aggressive and faster cut.
There are typically 2 or 3 settings plus a
0 setting for straight cutting which is
recommended for metal & thin materials
with the orbital settings for the fast straight
cuts such as ripping excess material.
The higher the orbital setting the rougher
the resulting finish.
What to Think About
What materials will it be cutting?
Type of handle configuration?
Are they replacing an old jigsaw (blade fitment)
Maximum cutting depths?
Is weight or physical size a factor?
Is it for professional or home handyman use?
Safety Hints
Wear approved safety equipment e.g. Ear Muffs & Goggles/Glasses
Wear a dust mask when cutting Perspex or similar
Ensure you have a good firm grip on handles
Keep work area clear and un-cluttered
Always clamp the work where possible
Keep powercords clear of blade and un-tangled
Check the tool is switched off before connecting to the mains
Start the tool prior to the blade making contact with the work
Keep the shoe firm and square to the work at all times
Check for blade clearance on the underside of the work piece
Do not over extend your body when operating
Use accessories that are in good sound condition
Ensure the accessory is fixed tightly to the tool
Let the accessory do the job
