Not clearing the chips | Bearing clogs, failure | Use a vacuum or brush to remove chips |
Q: What's the difference between a straight bit and a flush trim bit?
A: Straight bits do not have a bearing, while flush trim bits do. This allows flush trim bits to trim wood flush with other surfaces.

A: Yes, but it is recommended to use a plunge router for more precise control.
Q: How often should I replace the bearing?
A: Replace the bearing when it becomes loose or worn. This can vary depending on usage.
Q: What's the best way to sharpen a top bearing flush trim router bit?
A: Use a diamond grinding wheel or sharpening stone. Hold the bit at a 45-degree angle to the wheel and sharpen the edges evenly.
