Jigsaw blades explained
Which blades to use for each material/job
There are several different types of jigsaw blades available for various materials and speeds of cut. Choosing the right cutter for the job is essential in order to get the best finish and prolong the life of your power tool. Even if you have a relatively cheap jigsaw, with good blades you can get great results.
You don't have to spend big bucks to get decent blades but as always you get what you pay for. And the saying 'buy cheap buy twice' is as true as always with blades.
What difference does the number of teeth make?
The more teeth the blade has, the slower the cut. Less teeth = faster cutting.
More teeth also gives a cleaner cut. The less the teeth there are, the rougher the cut will be.
At least two-three teeth will always be cutting the material when in use. Use fine toothed blades for thin materials, and rough cutting blades for thick materials.
Different types of tooth design
Side set teeth - great for rough cutting work
Wavy set teeth - Best for fine, clean cuts
Conically ground straight blade (not off-set teeth) that are sharpened diagonally - Gives a more precise clean cut.
Side set teeth diagonally sharpened - for fast rough cutting.
What materials can you cut with a jigsaw?
Metal cutting blades
There are loads of different carpentry jobs I use my jigsaw for like skirting, kitchen fitting (including cutting kitchen worktops, sink/hob holes etc), scribing timber to irregular surfaces, cutting round pipes, roofing and more.
