TIMBERLINE by Amana 420-70 TIMBERLINE CLASSICAL MOULDING 2 Flute with Ball Bearing Guide This bit is designed for routing architectural and furniture moldings and trim. The profile is laid out vertically, reducing the diameter of the bit. This router bit should be used in a 2+ horsepower, table-mounted router, and should be run at reduced speed. Although it has a ball-bearing guide, guiding the cuts with the fence is recommended.
