1. Understanding the Jigsaw
What is a Jigsaw?
A jigsaw is a handheld reciprocating saw that uses a straight, narrow blade to cut a range of materials, including wood, plastic, metal, and laminate. Due to its ability to easily do both straight and curved cuts, the tool is simply unbeatable when it comes to complex tasks such as cutting circles. It features an up-and-down sawing knife that cuts through materials accurately and a thin blade, which gives it an advantage as it is easy to maneuver around curves and close angles.
Types of Jigsaws
Corded Jigsaws
The corded jigsaws offer constant power and are well-suited for long-term, continuous cutting jobs. They are more powerful than cordless jigsaws and are ideal for making cuts with thicker or tougher materials. However, the trade-off is portability; users must manage the cord while working, which can limit mobility.
Cordless Jigsaws
The cordless jigsaws, such as ONEVAN 135mm Brushless Cordless Jigsaw, are reasonably mobile and convenient. They can be used in small assignments or tasks that involve travelling in and around the workplace. Contemporary cordless jigsaws, in general, and brushless ones in particular, are very useful and have high performance, coupled with low vibration, and can therefore be used to cut precise circles.
2. Can a Jigsaw Cut Circles?
Yes, and it does so well when properly used. We should take a look at why jigsaws can be an excellent circle-cutting tool.
Flexibility
A jigsaw can cut through different materials of various forms and sizes. This can be used for both complex and straightforward cutting tasks involving circles.
Blades of Assorted Types
Blades vary widely, and you should be able to find blades suitable for the type of material you are cutting. For example, Fine-tooth blades are used with wood and metal, while special blades are used with laminates and plastics. The variety of blade options available for jigsaws ensures accurate and clean results.
Precision Cuts
A jigsaw can be used to make perfect circular cuts when the proper technique is employed or a circle-cutting jig is used. You will have better control over depth and curve with it than with many other tools available.
Convenience
The jigsaw is easy to use, as observed by most DIYers and beginners. With sufficient practice and attention to technique, it is possible to cut smooth, accurate circles.
Cost-Effectiveness
Jigsaws will be cheaper in comparison to routers or CNC machines, and they do not require such an elaborate setup.Even high-quality brands, such as ONEVAN Cordless Jigsaw, are affordable and versatile.
3. Range of Circle Sizes that a Jigsaw Can Cut
Cutting circles with a Jigsaw only needs practice and guidance. Keep reading to know how to cut a circle with a jigsaw.
Less than 2 inches (Small Circles)
Feasibility
When cutting tiny circles, a jigsaw can be challenging because the blade's size and turning radius may be too large for the task. However, with patience and a slow approach, it's possible.
Techniques
Drill a starting hole near the edge of the circle and insert the jigsaw blade into this hole to begin cutting along the tight curve. A blade with minute teeth will minimise the chances of a breakage.
Applications
Small diameters are frequently needed in cabinet making, electronic boxes and decorative work in wood.
Medium Circles (2 to 12 inches in diameter)
Feasibility
These are the optimal dimensions for using a jigsaw. With this size of circles, broad strokes of the blades can be easily followed, allowing for fine work to be done.
Techniques
A template or a circle cutting jig is best—these assist in keeping the radius constant and a smooth edge.
Applications
Widely used in cutting speaker holes, venting holes and craft projects.
Large Circles (21 to 3ft in diameter)
Feasibility
Large circles can be achieved with the right method. Select a blade that matches the material thickness and use a pivot jig for better control.
Techniques
Firm /Secure your material and make extra passes as required. Ensure that the material is securely fastened at the pivot point and guide the jigsaw steadily around the circle.
Applications
Commonly used in furniture manufacturing for applications such as round table tops, mirror frames, and garden planters.
Very Large Circles (More than 24 inches in diameter)
Feasibility
Cutting huge circles has been done, but more slowly. The size and cutting dome of the tool have to be considered.
Techniques
Use a DIY or store-bought circle jig that is mounted to the jigsaw. Work cautiously and apply even pressure during a cut.
Applications
Ideal for architecture, artistic installations and bespoke furniture.
4. Standard Materials for Jigsaw Circle Cutting
The difficulty of cutting circles with a jigsaw depends on the material. Continue reading to learn how to cut perfect circles with a jigsaw.
1. Wood
A jigsaw can be used to cut solid wood. Keep tear-out to a minimum by using a fine blade and clamping your material at all times to reduce movement.
2. Plywood
One of the best materials for a circular cut is plywood. It does, however, tend to splinter, so use a blade with a high tooth-per-inch (TPI) rating and mask the cut line with masking tape.
3. MDF (Medium-Density Fiberboard)
MDF is easy to cut, but it leaves behind large amounts of dust. Cutting MDF requires a sharp blade and effective dust extraction to manage the dust produced.
4. Acrylic and PVC or plastic
Plastics may become extremely hot and burn you or melt in the event of rapid cutting. Cut with a slow cutting speed and a fine blade to achieve clean results. A water or soap solution can be used to diminish friction.
5. Metal
Special blades of metal-cutting type can be used to cut thin aluminium or sheet metal. Take it step by step, avoiding overheating, and apply lubricant as needed.
6. Laminate
Laminate is hard and can easily chip. Masking tape will prevent damage to the surface, and a reverse-tooth blade will result in a smoother finish.
5. How to Cut a Circle with a Jigsaw
Basic Method to Cut a Circle with a Jigsaw
- Any Perfect Circle: Put a compass or a piece of string looped around a nail and sketch an ideal circle in your material.
- Drill Entry Hole: Make a hole in the circle close to the edge of the circle to fit the blade of the jigsaw.
- Push Blade In: Put the jigsaw blade into the hole.
- Follow the Line: Be slow as you move your jigsaw along the line of the circle with a steady pace and pressure.
- Finish and Sand: Remove one layer of foam to one thickness, plane it off with sandpaper or a rotary tool.
Using a Template to Cut a Circle with a Jigsaw
Make a Template: Make a pattern of the chosen circle using a cut-out of cardboard or thin wood.
Trace the Template: Follow the shape by tracing with the template on your material.
Bench: Use the jigsaw to run the outline.
Clean Edges: With a little sanding or filed edges, refine the shape.
Freehand Cutting Circle with a Jigsaw
Advanced users can cut circles with no assistance. Begin by marking your circle, make a hole in it with a drill and follow the curve at a slow pace with your hands only. It demands a slow pace and excellent control, and provides ample leeway and inventiveness in return.
