What is the best way to cut a circle in wood?The best way to cut a circle in wood, metal, and plastic depends on the size of the hole you want to cut out. The best way to cut small circles up to 5 inches, is to use a power drill with a hole saw kit, while cheap you can easily cut out a perfect circle shape quickly.
For cutting circles bigger than 5 inches you want to use a hand jigsaw or better a powered jigsaw. A powered jigsaw is designed to cut circles and curves easily, given that you mark out the line or curve you want to cut, and you guide the tool to the line you have marked.
There are a few other ways to cut circles using power tools like a band-saw, or you could even use a wood router if you have one around.
How To Cut A Circle Using A Power Drill
If you want to know how to cut a circle in wood without a jigsaw? The best way to do so if the holes are smaller than 5 inches is to use a power drill with the right drill bits. You can use either spade drill bits, or a hole saw kit, for bigger holes.
Drill A Circle In Wood Using Spade Bits
For circles smaller than 1 and a half Inches, you can drill bits known as spade bits. Spade bits are cheap drill bits made to quickly drill holes through timber mainly to run wires or do quick checkouts in framing timber. The bad thing about spade drill bits is that they leave a relativity messy cut. The spade drill bits, can blow out and split the wood when it comes out the other-side.
To avoid this first use a standard drill bit to drill a hole as a guide, then 2nd drill through both sides of the timber with a spade bit meeting in the middle to avoid this blow-out.
- Fast with only the need to mark the center
- Can blow out the back and leave a messy finish compared to a hole saw or standard drill bit.
- Maximum hole size is 1.5- Inches
- Can only be used for drilling holes in timber
How To Cut A Circle Using A Hole Saw
A hole saw can cut circles in wood, metal and plastic. A hole saw kit can cut a circle smaller than 5 inches quick and accurately, with only the need to mark the center of your hole.
Some hole saws can only cut wood, but most, however can cut all materials including steel, and drilling stainless steel.
- Perfect Circle, and tidy cut
- Quick with only the need to mark the center of the circle
- Can cut metal, and plastic as well as wood, depending on the hole saw kit
- Reasonably cheap kit to get if you have a power drill already
- Can only cut small to medium sized holes depending on the biggest hole saw in a kit.
How To Cut A Circle In Wood By Hand
How to cut a circle in wood by hand? If you want to stick to hand tools to cut out a circle in wood, and you need to cut out a hole bigger than what a hole-saw can do then you could opt for a coping saw. A coping hand tool is relativity cheap to buy, but is only really good for cutting the thinnest of wood materials, and is still a slow method of cutting curves and circles.
Coping saws are best for fine touch up’s in woodworking rather than cutting big circles out of wood, It would, however, be much more practical and faster to use an electric jigsaw.
- Good for tiding up small woodworking corners
- Good for woodworking when it comes to dovetails and finger joins
- Slow to use for any decent sized cut
- Blade tend to bend and not cut straight with materials that are too thick
- can be hard to keep the blade square with the wood surface, as there is no base plate like what an electric jigsaw has.
Best Way To Cut A Circle In Wood With A Jigsaw
How to cut a circle in wood using a jigsaw?An electric jigsaw is the best way to cut out a circle in wood, plastic and thin bits of metal using the right blade attachment. A jigsaw is a portable tool guided, free-hand to cut whatever shape or curve you want relatively quickly.
A jigsaw tool can be both corded and cordless, a cordless model can be easier to operate, but can also cost a little bit more to buy, the power a cordless model has, is sufficient for almost all jobs therefore a cordless jigsaw in generally a perfected choice.
- Fast as it is power driven
- Can cut any size shape, curve, circle or straight line.
- Changeable blades for different materials or types of metal and wood.
- You could use a timber guide to cut a circle more quickly and accurately if you don’t want to go freehand
- It is required for you to fully mark out the shape and edge of your cut out.
- The cut might be a little jagged compared to a perfect hole-saw cut out, therefore, you might need to touch up your cut with some sandpaper at the end
How To Cut A Circle In Wood With A Router
How to cut a circle in wood with a router? I have never done this but it is possible to use a wood router to cut out a circle in wood if you don’t have other tools like a jigsaw on hand. Depending on the thickness of wood you are cutting you would need to do the cut in multiple rounds, to avoid the router from being over-worked.
It is a bit of complicated set-up to just cut a simple circle. But as the video from youtube below shows, you could even use this technique to cut circle patterns as well as a full cut. You could just make the jig out of a piece of wood with a screw in the middle.
- Good For woodworking, less sanding needs to be done compared to a jigsaw
- Not very time efficient, as it takes a while to set up and cut
- Requires a big working space
- Unless you already have a router, I wouldn’t get one to only cut a circle
Cut A Circle With A Band Saw
A band-saw is another way to cut circles in wood if the material is small enough to be lifted on to the band-saws table.
Band-saws are not the cheapest or easiest way to cut circles in wood however they are a good way to cut thicker gauged metal projects if you know someone that will let you use theirs. Band-saws have more grunt and less blade flexibility than a jigsaw, making them more ideal for more heavy cutting jobs, but they are not cheap or portable like an electric jigsaw tool, making band-saws only suited for commercial workshops.
How To Mark-out A Perfect Circle To Cut
After you have picked a circle cutting tool for your job you want to mark-out the cut-out. The best way to mark out a circle is to first mark the center.
Next, you want to tie a piece of string to the tip of your pencil and cut the string to the length that you want the radius to be. You can then attach the string to a screw in the middle and you can now use the string to guide your pencil to perfectly mark your circle on your wood, plastic or metal surface.
