Amana PLUNGE 3/16DIA UPPER BB 1/8SHK 47220

This exclusive miniature bit features a 3/16" diameter ball bearing guide that is much smaller than other ball bearing router bits on the market. Ideal for small fine work and delicate projects such as signmaking, guitarmaking/luthier work, toymaking, routing letter edges, flush trimming, plunging tight corners and confined areas with high production.

This bit is essentially a plunge-cutting straight bit with a shank mounted ball-bearing pilot. It is a versatile bit, useful for template/pattern routing of parts, joints, and internal cuts. It can be used in handheld and table-mounted routers.

The template is attached to the workpiece, and the pilot bearing rides along its edge as the cutting edges rout the workpiece, forming an exact duplicate of the template.

With a handheld router, the pattern is on top of the work; with a table-mounted router, the pattern is underneath the work.
