How to use

Mount the straight bit securely in a compatible router or trim router according to the tool manufacturer’s instructions. Set the cutting depth to match the required groove or hole depth, feed the router steadily along the workpiece, and maintain a consistent feed rate to avoid burning or uneven cutting. Use appropriate clamps or a guide for accurate routing and keep hands clear of the bit while operating.

Recommendations

For best results, use the bit at the router speeds and feed rates recommended for the workpiece material, make multiple light passes for deeper cuts, and ensure the bit is sharp and clean. Wear appropriate eye and hearing protection and follow all safety instructions for your router.
