In this article, we will explore the reasons why router bits have bearings and how they enhance your woodworking experience.
The Function of Bearings in Router Bits
Router bits with bearings are commonly referred to as bearing-guided bits. The primary function of these bearings is to act as a guide, controlling the depth and direction of the cut. The bearing on the router bit follows the edge of the material, allowing you to create consistent and repeatable cuts. The bearing acts as a fence or guide, ensuring that the router bit stays in line and doesn’t veer off course. This makes it easier to achieve accurate and uniform cuts, especially when working on curved or irregularly shaped pieces.
The placement of the bearing on the router bit is strategic. It is usually positioned above the cutting edge of the bit, allowing the bearing to ride along the edge of the material while the cutting edge removes the excess material. The bearing acts as a reference point, dictating the depth of the cut and preventing the router bit from digging too deep into the material. This helps to prevent mistakes and ensures that you achieve the desired outcome with every cut.
The Benefits of Using Router Bits with Bearings

Furthermore, bearing-guided bits are excellent for replicating patterns or creating multiples of a specific shape. The precise guidance provided by the bearing ensures that each cut will be identical, allowing you to reproduce the same design multiple times without any variations. This is particularly useful for tasks like creating consistent moldings or producing multiple identical pieces of furniture.
4. Safety
Bearing-guided router bits also contribute to enhanced safety during operation. The bearing acts as a protective barrier, preventing the cutting edge of the bit from coming into direct contact with your hand or the material. This reduces the risk of accidental cuts or injuries, providing a safer woodworking environment.
In addition, the bearing helps to reduce kickback during operation. Kickback occurs when the router bit grabs the material and violently throws it back towards the operator. The presence of the bearing helps to stabilize the router bit and prevent it from catching or digging too deep into the material, minimizing the chances of kickback.
Tips for Using Router Bits with Bearings
When working with router bits that have bearings, there are a few tips to keep in mind to ensure optimal results and longevity of your tools:
1. Choose the Right Size Bearing
Router bits with bearings come in various sizes, and it’s important to select the appropriate bearing size for your desired outcome.

Be sure to refer to the manufacturer’s guidelines or consult a woodworking expert for guidance on choosing the right bearing size for your specific project.
2. Maintain Proper Bit Height
When using a router bit with a bearing, it’s crucial to set the bit height correctly. The bearing should be in contact with the material while the cutting edge is slightly raised above the surface. This ensures that the bearing properly rides along the edge, controlling the depth of the cut. Failing to set the bit height correctly can result in an improper cut or a damaged bearing.
3. Take Incremental Passes
For larger or deeper cuts, it’s advisable to take incremental passes rather than attempting to remove the material in a single pass. This allows the router bit to work efficiently and minimizes the strain on the tool and the material. Taking small passes also allows you to maintain better control over the cut, ensuring accuracy and preventing any potential damage.
By following these tips and practicing proper safety precautions, you can maximize the benefits of using router bits with bearings and elevate your woodworking skills to new heights.
