A jigsaw is one of the most versatile power tools you can have in your workshop. It can cut through materials such as wood, metal, laminate, and PVC, as well as make straight and curved cuts easily. When working with a jigsaw, make sure to use the correct blade for the material you’re cutting and wear safety gear.

Choosing and Installing the Right Blade

  1. Carbon steel blades are the standard material used in a jigsaw. If your project requires you to cut through wood, PVC, or laminate, find a hardened carbon steel blade. [1]
    • Most blades will be labeled with the type of material they can be used on. Look on the packaging or on the label printed directly on the blade.
  2. Since metal is a harder material, you need a tougher blade to cut through it. Bi-metal blades have hardened steel teeth to make the cut and a softer, flexible body so they don’t break. Find a blade or set of blades meant for metal cutting. [2]

  3. Fine-toothed blades have more teeth on the blade per 1 inch (2.5 cm). Fine-toothed blades are standard for cutting metal or making a clean edge on wood. [3]
    • Wood blades tend to have as many as 12 teeth per 1 in (2.5 cm), while metal blades can have up to 36 teeth per 1 in (2.5 cm).
    • Fine-toothed blades work best when they’re used at a slower speed so they don’t break.
  4. Coarse-toothed blades have fewer teeth per 1 inch (2.5 cm) and are mostly used to cut wood. If you need to make cuts quickly for a project, opt for a coarse-toothed blade to finish faster. [4]
    • Coarse-toothed blades leave a rough surface and will chip wood.
  5. A T-connection blade has 2 notches near the top of the blade on each side. Feed the blade through the bottom shoe, the flat guard on the bottom of the saw, until the end fits into the quick release. Make sure the blade’s teeth are facing towards the front of the saw. Push the blade into the quick release until it clicks into place. [5]
    • The type of connection you need depends on the model of your jigsaw. Check your jigsaw’s manual to see what type of connection you need.
    • Some quick releases have a small lever you need to turn before the blade locks in. Try pulling on the blade once you insert it to make sure it fits tight.
    • To remove the T-connection blade, pull on the lever on the quick release and pull the blade out.
    • Make sure your jigsaw is unplugged or disconnected from power before you change the blades.
  6. U-connection blades have a single notch on top. Put the U-connection blade through the shoe of the jigsaw and hold it in place in the release. Tighten the screw that holds the blade in place with an Allen wrench or screwdriver until it doesn’t wiggle anymore. [6]
    • To remove the blade, simply turn the screw counterclockwise and pull the blade out.

    Tip: Some jigsaws can accept both T-connection and U-connection blades. Read the user manual for your jigsaw to see what kind of connections it's compatible with before purchasing new blades.

Learning the Basics

  1. Once you have your saw blade secured, plug the cord into a nearby outlet so you can reach all the areas you need to cut. If you have a cordless jigsaw, insert the battery pack into the port on the back of the machine. [7]
    • Whenever you aren’t using your jigsaw, unplug it so you don’t accidentally turn it
    • Coil the cord once around your dominant arm so the cord doesn’t hang down loosely.
  2. Before you make any cuts, cover your mouth and nose with a face mask so you don’t inhale any dust. Protect your eyes with safety glasses in case any of your material kicks back towards you. [8]
  3. Make sure the area where you plan on making your cuts extends over the edge of your work surface. Use at least 2 C-clamps on the edge of your work surface to hold the material sturdy. If it still moves around easily, use additional clamps or rest a heavy object on the opposite end of the material. [9]
    • If you need to cut a hole in the center of your material, balance it between 2 sawhorses so you can easily cut through it without damaging your work surface.
    • You don’t need to use clamps if you’re making a vertical cut on a wall.
  4. Locate the power trigger underneath the handle on top of the saw. Pull the trigger to start the blade, and keep it held down until you’re finished with your cut. [10]
    • Most jigsaws have a lock switch next to the trigger. If your jigsaw has one, push it with your thumb to lock the trigger in place so you don’t have to hold it the whole time.
  5. Locate the dial on the front of the machine above the blade to adjust the speed. The blade moves faster when the dial is set to a higher number. Keep the speed slow at first until you get used to using your jigsaw. [11]
    • Use a slower speed when you need to make accurate cuts or when you’re cutting through metal.
    • Some jigsaws have a variable-speed trigger, meaning the blade will move faster when you squeeze it harder. [12]

    What Speed Should You Use?

    Use a slow speed setting for metal or PVC so it doesn't melt the material. [13]

    Use a faster setting for wood or laminate to reduce the number of vibrations while you're cutting. [14]

  6. Use a straightedge or a compass to trace the line that you want to follow with your jigsaw. When you make your cut, follow along the outside of the mark so you don't accidentally overcut your material. [15]

Making Various Cuts

  1. Start at the edge of the material you’re cutting and slowly push the blade through it. Go slow at first, making sure to follow along with the line you want to cut. Keep the shoe (or the base plate) flat against the material you’re cutting to ensure you’re making a straight line. Continue guiding the saw until you completely cut through the material. [16]
    • Don’t force the machine through your material since you may break the blade if you push too hard. Let the machine do the work for you.
    • Keep your fingers away from the saw while you’re cutting since the blade is exposed.
  2. Install a fine-toothed blade and set the speed of your saw to the slowest setting. Slowly guide your saw along the curve you’re cutting out, turning the back of the saw in the opposite direction of where you want the blade to go. [17]
    • Use a compass tool to draw the curved lines on your material to ensure you get a smooth outline. That way, as you work through the curve, the material will fall out in smaller pieces and relieve the pressure on the blade

    Tip: When making cutouts, cut straight relief lines in from the edge to your cut line every 3–4 in (7.6–10.2 cm) . That way, as you work through the curve, the material will fall out in smaller pieces and relieve the pressure on the blade.

  3. Look for a screw on the bottom or back of the shoe, and turn it counterclockwise to loosen it. Adjust the angle of the shoe to the angle for your cut and tighten the screw to secure it in place. Set the shoe flat against the surface you’re cutting. Your blade should now be at the angle needed for your cut. [18]
    • Miter cuts are common for making 45-degree angles and creating clean joints between wood.
  4. Start with a drill bit that’s slightly larger in circumference to the width of your saw blade. Drill a hole in each corner of the area you want to cut out. Feed the saw blade one of the holes and turn it on. Follow along with the outline for the area you want to cut out towards one of the other holes you drilled. Work from hole to hole until you’re finished with your cuts. [19]
    • This allows you to make a cut out in the middle of the material without cutting in from the edge, like if you needed space for a vent or outlet.

    I'd recommend using a fine-toothed blade and setting the jigsaw speed to the lowest setting. Go slowly, turning the back of the saw in the opposite direction of the curve you want to cut. Using a compass to mark smooth curved lines on the material also helps guide clean curved cuts.

    One tip is to clamp a straight piece of wood onto your work material as a guide. Run the jigsaw along that straight edge, keeping the jigsaw's base plate tight against the guide. This helps make straight cuts using a jigsaw blade. You can also drill starter holes to insert the blade into.

    The power cord should be behind the saw at all times while you're cutting. Wrap it around your arm if you want to make sure it doesn't fall out of place.
