At which speed should you use your jigsaw?
When using your jigsaw, the speed you require will primarily depend upon the material you are cutting.
However, you may also need to adjust the speed of your tool depending on the intricacy of the cut you are making.
Most jigsaw manufacturers do not specify the exact speeds represented by the graduations on their numbered speed control dials.
In their user manuals, they will refer to the speeds as simply low speed, medium speed or high speed. As a general guide, high cutting speeds are those greater than 2000spm and lower speeds are around 750spm.
Materials such as softwoods benefit from a fast cutting speed.
This is because higher speeds produce less vibration, enabling the jigsaw blade to more efficiently work its way through the material.
On the other hand, for denser materials such as plastic, hardwoods and metal, a lower speed setting should be selected.
Using too high a speed to cut these materials is likely to cause both the workpiece and the blade to overheat. This will reduce the life of your blade and could potentially damage your workpiece.
The type of cut you will be making will also have an effect on the speed your jigsaw should run at.
For straight cutting, a slower speed should be used to prevent the blade from pulling the saw away from the cutting line.
Depending on the material being cut, curve cutting should be carried out at a moderate speed.
More detailed scroll cutting, on the other hand, requires a slower cutting speed to give you greater control over the jigsaw.
