Listed specifications

Choose this model

Choose FTRB15 when the drawing calls for the listed 18 mm cutter, 12.7 mm bearing and three-flute configuration.

The table reports the dimensions listed for this series. Select by the required cutter and bearing geometry rather than the model number alone.

Setup and test cut

• Confirm that the router or spindle accepts a 1/2 inch shank and provides the required collet engagement.
• Check the template thickness, bearing contact and cutter clearance before starting the machine.
• Keep the material overhang within a controlled test setup; do not use the bit for unsupported heavy removal.
• Make a shallow test cut in matching scrap, then inspect the dimensions, bearing travel and edge before cutting the finished part.
