I've got heaps of different types of Jigsaw Blades that I keep ready in my Jigsaw box and I'll go through my favourite blades to use for a few of the most common jobs & materials I come up against when using my Jigsaw at home and on site too.
I use my jigsaw for all sorts of jobs like cutting/scribing skirting boards, kitchen fitting (including cutting kitchen worktops, sink/hob holes etc), scribing timber to irregular surfaces, cutting round pipes, for roofing and more.
The jigsaw is an incredibly versatile tool, there are some jobs I wouldn't use anything else for and sometimes it just comes in handy & gets you out of the $hit when no other tool would really work that well!
Choosing the right cutting blade for the job is essential not only to get the best cut but also because you can prolong the life of your power tool & blades.
Finally you don't have to spend big bucks to get decent blades they are actually some of the cheapest power tool blades you'll buy and they can wear out quickly if not used correctly.
Your power tools are only as good as the blades you have in them!
The best type of Jigsaw blade to choose / use will depend on these factors:
The first thing to identify is the type of shank your jigsaw blades need to have in order to fit your Jigsaw properly.
The shank is the top section of the blade that slots into and is gripped by the jaws of the Jigsaws clamping mechanism.
There are two types of Jigsaw shank; T-Shank blades (Tang shank) & U-Shank (Universal) blades.
If you are buying a new Jigsaw, aim for one that uses T-Shank blades if possible, it is the newest and best performing type and quick release Jigsaws use T-shank blades.
The number of teeth a jigsaw blade has makes a big difference to the speed & type of cut it will make.
There are different teeth designs for different Jigsaw cuts as well
When cutting sheet metal or pipes with a Jigsaw, I have found Bosch HSS Jigsaw blades to be the best combination of value and performance. I also clamp the metal down whenever possible to stop it rattling up and down and use a medium speed at first, but speed up as much as possible provided the tool is cutting well and the blade isn't trying to wander at all.
It doesn't hurt to clamp a straight edge on to guide the Jigsaw if you need a straight cut for longer than a couple of inches - takes a little longer to set-up but makes cutting a neat line much faster.
These are also great Jigsaw blades for cutting things like door handle spindles to length as well (clamped in a vice)
You've probably heard me say a dozen times through this site, man made & laminated materials can absolutely annihilate the cutting edges of blades and therefore you must use blades specifically designed to cut laminated boards or completely ruin pretty much any other type.
For things like laminate floor boards, 44mm thick Laminated kitchen counter-tops or even laminated formica such as kitchen cabinets or bedroom furniture, I really like Dewalt Downward cutting Jigsaw blades
No matter what blades you use on these materials they will wear out quickly. These are good value so you can change them as soon as they get dull and because they cut on the downward stroke you get a really clean cut from the face side (you don't need to mark out the cuts on the back of the boards).
I really like Dewalt XPC Jigsaw blades with Plunge cutting tips for almost all cuts I make with my Jigsaw in soft woods and even some soft plastics too.
It is handy not having to drill a hole before you can plunge the Jigsaw blade (slowly) into a material especially when cutting a square or round hole in the middle of a sheet of ply for example.
I use these blades for Plywood, Hardwood, Softwood, Cutting letterbox holes in doors, cutting skirting boards and sometimes even for cutting roof rafters during roofing work as well.
They come in a great little box that keeps them safe from getting knocked around and damaged and they last ages provided you don't go too fast they heat up too much (the same is true for all blades not just these).
The Jigsaw has been designed for the blade to cut on the upward stroke - because this means the cutting force is then being used to pull the material and the Jigsaws flat bed closer to one another so only the blade is moving.
For this reason most Jigsaw blades teeth are pointing slightly upwards and therefore cut on the upward stroke.
The downside to this is the material can tear out as the teeth come up through the surface. For rough timber that wont be seen this doesn't matter. For fine work that will be left exposed, it isn't ideal.
To prevent this, you can either turn the material upside down and cut from the back or even better buy Jigsaw blades that cut on the downward stroke instead.
These downward cutting Jigsaw blades are much better for getting a perfect cut as you can cut the material face side up and see exactly the line you are cutting to and they wont tear out or cause splintering at all.
