Understanding Top Bearing Router Bits
What are Top Bearing Router Bits?
Top bearing router bits are specialized router bits that feature a bearing mounted on the top of the cutter. This design allows the router bit to follow the edge of a template or the surface of the material, providing a consistent cutting depth and shape. They are particularly useful for flush trimming, pattern cutting, and edge profiling.
The Importance of the Bearing
The bearing plays a crucial role in the functionality of these bits. It acts as a guide that helps maintain the correct position of the router bit as it moves along the material. The accuracy of the cut depends on the quality and size of the bearing, making it vital to choose the right type for your specific project.
