In this article, we will explore the different router bits specifically designed for cutting circles, their features, and how to choose the right one for your project.
1. Straight Router Bits
Straight router bits are the most basic type of router bit available, and they can also be used to cut circles. These bits have a flat bottom and straight cutting edges, allowing them to plunge straight into the material and follow a circle template. When using a straight router bit, it is important to secure a pivot point in the center of the circle, such as a nail or screw, so the bit can rotate around it smoothly. Straight router bits are commonly available in various diameters, so you can select the size that matches your desired circle diameter.
Additionally, straight router bits can be used to cut circles in a variety of materials, including wood, plastic, and even soft metals. However, they are best suited for softer materials, as cutting circles in hard materials may cause premature wear on the bit. To enhance safety and precision, consider using a circle cutting jig or a template to guide the router along the desired path.
Overall, straight router bits are versatile tools that can effectively cut circles when used with the appropriate technique and safety measures. However, if you’re looking for more specialized bits specifically designed for circle cutting, there are other options to explore.
2. Spiral Router Bits
Spiral router bits are a popular option for cutting circles due to their unique design. Unlike straight router bits, spiral bits have spiraling cutting edges that resemble a drill bit. This design allows them to cut smoothly through a variety of materials, including wood, plastics, and even harder materials like aluminum. When used for circle cutting, spiral router bits provide clean cuts and reduce the likelihood of chipping or tear-out, especially in delicate materials.
One of the key advantages of spiral router bits is their ability to plunge straight into the material without the need for a pilot hole or pre-drilling. This makes them particularly useful when cutting large circles or creating circular shapes within a piece of material. However, it’s important to note that spiral bits may produce more sawdust due to their design and require a vacuum or dust collection system for efficient chip extraction.
When selecting a spiral router bit for cutting circles, consider the diameter of the bit in relation to the desired circle size. Additionally, pay attention to the flutes on the bit, as these help with chip evacuation and can impact the overall cutting performance. Overall, spiral router bits are a versatile option for cutting circles and are worth considering for your woodworking or DIY projects.
3. Roundover Router Bits
If you’re looking to add a decorative touch to your circles, roundover router bits are an excellent choice. These bits are specifically designed to create a rounded edge or profile along the circumference of the circle. The rounded profile adds a smooth and polished look to the edges, making it ideal for projects such as tabletops, plaques, or decorative accents.
Roundover router bits typically have a bearing on their tip, which allows the bit to follow a template and shape the edges of the circle uniformly. Since the roundover bit is not meant to cut the entire circle, it is often used in conjunction with a straight router bit or a spiral bit to first cut the circle and then add the roundover profile. This combination can produce stunning results and elevate the aesthetic appeal of your woodworking projects.
When selecting a roundover router bit, consider the desired radius of the rounded profile. Roundover bits are available in various radii, allowing you to choose the curvature that best suits your project. It’s also important to note that roundover bits are typically used in a handheld router, making them convenient and versatile for both small and large-scale projects.
Key Takeaways: What Router Bit to Cut Circles?
- A straight bit can be used to cut small circles with a fixed radius.
- For larger circles, a spiral bit with a guide bearing is an excellent choice.
- A core box bit is perfect for creating deep, rounded cuts for decorative purposes.
- When cutting circles in thick materials, a bowl and tray bit provides smooth results.
- Always wear safety goggles and use proper clamping techniques when working with a router.
