Choosing the Right Blade

How to Cut Circles with a Jigsaw - Choosing the Right Blade

Selection of the suitable blade is critical when sawing circles with a jigsaw. There are numerous varieties of blades at one’s disposal, and each is intended to slice through exact fabrics and thicknesses.

Different blade types that are suitable for cutting circles include high-carbon steel, bi-metal and tungsten-carbide. High-carbon steel blades are cost effective and perfect for cutting circles in wood or plastic.

Bi-metal blades are an excellent choice as they possess more durability and can smoothly handle denser materials like metals or tiles. The strongest, albeit most expensive option is the tungsten-carbide blade – perfect for slicing through tough substances such as fiberglass or cement board.

When selecting a blade, it is important to take into account the material being cut and its thickness. For thicker materials, blades with larger teeth should be used, while thinner materials call for blades with smaller teeth. Additionally, pay attention to the number of teeth per inch (TPI) which dictates the speed and quality of the cut. Higher TPI blades give smoother results but they cut slower.

An important factor to ponder when sawing circles with a jigsaw is the longevity of the blade. If the material being cut is hard or thick, then the blade can lose its edge quickly. To maximize the lifespan of a jigsaw blade, the right accessory for that specific material should be used and an appropriate cutting method needs to be employed. Additionally, lubricating it with oil or wax can reduce abrasion and amplify its life expectancy.

Choosing the correct blade when using a jigsaw to cut circles in wood is essential. Carefully consider the material being cut, the number of teeth per inch on the blade, and how long it will last when selecting your blade.

Preparing the Workpiece

How to Cut Circles with a Jigsaw - Preparing the Workpiece

Before utilizing a jigsaw to make circular cuts, the workpiece should be correctly prepped to guarantee precise and flawless results and prevent any harm from occurring during the process.

Secure the project with clamps or other holding tools to an even surface to prevent uneven cuts and protect the material while cutting circles.

Secure your workpiece, then mark its center point with a ruler. To draw the outline of the circle, you can either use a compass or make your own jig. Cut a square of plywood and drill a circular hole in its middle, then attach a pencil to the hole via screw. Put the jig on the material while aligning the pencil to it; thereafter rotate it to draw the outline of the circle.

Once the perimeter is outlined, it’s vital to make sure that the item to be cut is horizontal and even so that the saw blade will not curve or snap off while cutting. Check the surface’s evenness with a level or ruler and if need be, use wedges to make it perfectly flat.

Secure the workpiece firmly, mark the center of the circle, and make sure it lies flat – these are essential for achieving precise and tidy cuts with a jigsaw. In the next part in this beginner’s series, I’ll discuss how to set up your jigsaw and make the cut.

Setting up the Jigsaw

How to Cut Circles with a Jigsaw - Setting up the Jigsaw

Once the workpiece is ready, the next step is to equip the jigsaw to start slicing circles. There are two methods to achieve this with a jigsaw: cutting by hand or employing a circle jig.

Hand-cutting works best for small and simple circles, whereas a circle jig provides superior results when dealing with more sizeable or intricate shapes.

To make a freehand cut with a jigsaw, begin by selecting and inserting the appropriate blade suited for the material. Make sure to use one equipped with fine teeth for cleaner results. Then, adjust the roller guide to the desired height for cutting through the material’s thickness; it should stick out from the base plate enough to pass through, leaving some room to spare.

To use a jigsaw circle jig to assemble the jigsaw, affix the jig to the base of the jigsaw and reset the cutting radius to your desired measurement. The pivot point of this handy tool revolves around the heart of the circle, providing accurate cuts.

To get the most precise cut, accurately align the jigsaw blade following the outlined circumference. Make sure that the teeth are pointing downward so that material doesn’t unintentionally rip or tear during cutting circles.

It is essential to adjust the speed of the jigsaw depending on the material being cut. Utilizing a slower pace with softer items helps counteract melting or deforming, while more rigid materials necessitate a quicker rate to avoid overheating and blunting the blade.

Completing the jigsaw properly is essential for creating precise, clean circle cuts. Select the suitable cutting technique, regulate the blade and speed, as well as utilize a circle cutting jig for more accurate results.

Cutting Techniques

How to Cut Circles with a Jigsaw - Cutting Techniques

Having arranged the jigsaw correctly, it’s now time to begin cutting the circle. Depending on its dimensions and details, a selection of techniques can be used to complete this task.

For circles of small sizes, the best method is to use a freehand cutting technique. Begin with the jigsaw and guide its blade carefully along the circumference of the marked circle, making sure to keep it upright against the material. Move it in a steady and continual motion without applying too much pressure or moving too rapidly as this can result in an uneven cut.

For more expansive or intricate circles, the circle cutting guide for jigsaws is the ideal tool. You can buy one that suits your jigsaw or you can DIY this jig. You can see how to make a circle cutting jig for jigsaws in this article.

Secure the jig to the bottom of your jigsaw, and then pivot it around the circle’s center point while you guide the blade along its marked edge.

Maintain a perpendicular angle between the blade and workpiece as you smoothly move the jigsaw in a continuous motion. To get optimal results, turn the workpiece as necessary to keep the jig steady around the circumference.

To achieve a perfect cut while cutting circles, it is crucial to handle the jigsaw correctly. Using both hands, firmly and securely grip the jigsaw and follow the edge of your marked circle. Make sure to maintain the blade perpendicular to the material and avoid any jerking or twisting in order to prevent a crooked cut.

Glide the jigsaw steadily along, being mindful not to pause during mid-cut; otherwise, you can end up with an unpolished and unequal cut.

To sum up, choosing an appropriate technique for cutting circles depends on the size and intricacy of the shape. To be precise, keep the jigsaw level and run it correctly along its path. For best results, move it steadily at all times.
