| Jointing Bit | Cuts mating edges for edge-to-edge joints |
| Cove Bit | Creates cove cuts for decorative moldings and trim |
Features and Benefits
- Precise Cutting: The top bearing guides the bit, ensuring accurate and consistent cuts, even on curved or irregular surfaces.
- Reduced Tear-Out: The top bearing also prevents tear-out, resulting in clean and splinter-free edges.
- Versatility: Top bearing router bits are available in a wide variety of sizes and shapes, making them suitable for a multitude of tasks.
- Durability: High-quality top bearing router bits are made from durable materials, such as carbide, for long-lasting performance.
Success Stories

Effective Strategies
- Use a sharp bit for clean cuts and reduced tear-out.
- Test the bit on scrap wood before using it on your project.
- Clamp the workpiece securely to prevent movement during routing.
- Feed the bit into the workpiece slowly and evenly.
- Use a router table for increased stability and accuracy.
Common Mistakes to Avoid
- Using a dull bit can result in rough cuts and excessive tear-out.
- Forcing the feed rate can cause the bit to burn the wood.
- Not clamping the workpiece properly can lead to inaccurate cuts.
- Using the wrong type of bit for the task can compromise the quality of the cut.
Challenges and Limitations
- Limited Depth Adjustment: Top bearing router bits have a limited depth adjustment range, which may not be suitable for deeper cuts.
- Potential for Chip-Out: When routing end grain, there is a risk of chip-out, especially with large-diameter bits.
- Uneven Cuts on Irregular Surfaces: On curved or uneven surfaces, the top bearing may not provide consistent support, resulting in uneven cuts.
