How to Use a Jigsaw Safely and Effectively

Jigsaw uses are countless. Whether you need to cut pipes in a tight under-sink location, shape the corners of a countertop, trim a tree branch or make circular holes for cornhole boards, this versatile handheld power tool is up to the job. You can even carve a pumpkin with a jigsaw. But any tool is only as good as its operator, so before you get cutting, learn how to use a jigsaw properly.

What is a jigsaw used for?

With the right blade, a jigsaw can be used to cut all sorts of materials, including wood, metal, tile, ceramics and plastic. You may find yourself using a jigsaw for straight cuts, but jigsaws really shine when you need to make curved, circular or irregular cuts in a material, especially in wood.

When to use a jigsaw

Jigsaws are best for short or shaped cuts rather than long cuts that require a straight edge. They don’t work for cutting thick wood, so if you’re trimming hardwood that’s thicker than ¾ of an inch or softwood thicker than 1.5 inches, use a circular saw instead.

Here’s where jigsaws come in handy:

• Cutting a circle in wood, for projects such as making frames or game boards

• Trimming laminate countertops or cutting a hole for a sink into a countertop

• Cutting floorboards or roofing to size

• Creating a miter cut or beveled edge on wood trim

• Cutting specific shapes out of metal or wood for decorative projects

• Cutting PVC tubing and pipes for plumbing or electrical projects

• Cutting drywall to size

Using a jigsaw: How to cut curves, straight lines and circles

The principles of using a jigsaw are the same no matter what you’re cutting. For most cuts, you should start at the edge of the material and follow these steps.

1. Mark the cutting line using a pencil.

2. Secure the workpiece. If you’re using a top-grip jigsaw, which can be operated with one hand, you can use the other hand to hold the workpiece, though holding the jigsaw with two hands is safer. If you’re using a barrel-grip jigsaw, which requires two-handed operation, clamp it to a workbench.

3. Rest the saw shoe, also known as the base plate, on the workpiece. The blade should be close to the workpiece but not touching it.

4. Check your settings. A normal, or reciprocal, setting is fine for most materials. An orbital setting, if your saw has one, is best for wood or laminate. Reciprocal settings and lower speed settings, which give you a slower cut, are helpful for cutting curves and intricate patterns.

5. Pull the trigger to start the saw.

6. Push the saw gently along the cutting line. Keep the saw shoe flat.

7. Release the trigger when the cut is finished. Wait until the blade is completely stopped, then withdraw the saw and put it to the side.

How to use a jigsaw to cut a straight line

You can cut a straight line with a jigsaw, but it’s not always easy. For longer straight cuts, the trick to keeping the line straight is to use a straightedge guide such as a straight wood board, a rip fence or a steel square. Clamp the straightedge guide to the workpiece, or clamp both to a work surface, and push the saw against the guide, following the steps above.

How to use a jigsaw to cut a circle

A jigsaw is the best tool to cut shapes in wood. But if you’re cutting a circle or other shape that doesn’t start at the edge of the material, you’ll need to create a starter hole. This allows you to insert the blade and get your jigsaw set up properly before you start cutting.

There are two options for creating a starter hole. You can drill a ½-inch hole into the material on the inside of the circle or other shape that you plan to cut, or use a plunge cut. A plunge cut is a good approach when you don’t have a drill on hand and you don’t mind having to discard some of the material.

To make a plunge cut, tilt the jigsaw, pivoting on the front of the saw shoe. The blade will be parallel to the workpiece. Start the drill and slowly tilt the jigsaw back so the blade plunges into the workpiece until the saw shoe is flush on the material and the blade points through it.

Once you have a starter hole, carefully follow the cutting line. You may need to stop and reposition yourself to get a good angle. If you do, be sure the blade isn’t touching the material when you restart the saw.

Jigsaw tips and tricks

The more you use a jigsaw, the better you’ll get. These tips and tricks can help you achieve clean cuts.

• Use the right blade for the job. High carbon steel, high speed steel, bi-metal, tungsten carbide and diamond blades are designed to cut different materials.

• Allow the blade to reach full speed before it touches the workpiece.

• Stay outside your cutting line. You can sand down the edges if precision is important.

• Don’t push the saw aggressively or apply any side pressure. Allow the jigsaw to drive itself forward while you guide it along.

• Clamp thin metal to plywood before cutting it. This will reduce vibrations and help you get a cleaner cut.

• Make sure there’s enough space below the workpiece for the blade to move freely. If you’re using a workbench, you may need to use rails to raise the workpiece.

How to use a jigsaw safely

Jigsaws are easy to use, but safety is still important. To protect yourself from injury, follow these safety tips.

• Don’t wear loose-fitting clothing that could get caught in the saw.

• Tie back long hair.

• Wear safety glasses and a mask or respirator.

• Use the right blade for the material, and make sure it is sharp and straight. Dull blades increase the risk of kickback.

• Remember that the blade of the jigsaw will extend beneath the material you’re cutting. Keep that area clear. Never put your hands under the work surface.

• Keep the saw shoe flat on the surface of the workpiece while you cut, except when making a plunge cut.

• Don’t lift the jigsaw from the workpiece until the blade has stopped.

• Keep track of the jigsaw cord and any other people in the room. Make sure they are away from the path of the blade.

Jigsaws can be complex and you should always consult with an expert regarding the specific circumstances, applicable rules and regulations related to your site and to your situation.
