Router Top Bearing Bits: A Comprehensive Guide to Upgrading Your Routing Capabilities

What is a Router Top Bearing Bit?

A router top bearing bit is a specialized type of router bit that is designed to be used with a router table. These bits have a bearing on the top of the bit that guides the bit along the surface of the workpiece, ensuring a smooth and accurate cut.

Why Use a Router Top Bearing Bit?

Router top bearing bits offer several advantages over standard router bits:

• Increased accuracy: The top bearing ensures that the bit follows the template or guide precisely, resulting in cleaner and more accurate cuts.
• Reduced tear-out: The top bearing prevents the bit from digging into the workpiece, reducing tear-out and improving the finish of the cut.
• Safer operation: The top bearing prevents the bit from climbing up the workpiece, making it safer to use than a standard router bit.

Types of Router Top Bearing Bits

There are various types of router top bearing bits available, each designed for specific applications:

• Straight bits: Used for cutting straight lines or dadoes.
• Flush trim bits: Used to trim edges flush with a template or guide.
