These flush trim plunge router bits are versatile, useful for template/pattern routing of parts,
joints, and internal cuts, and can be used in hand-held and
table-mounted routers. They are essentially plunge-cutting straight with shank-mounted ball-bearing pilots.
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 hand-held router, the pattern is on top of the work; with a table-mounted router, the pattern is underneath the work.
#47220 and #47222 have a mini 3/16" dia. ball bearing, while #47224 has a mini 1/4" dia. ball bearing.
#45481 for use on hardwood and flooring medallions.
47220, 47222 & 47224 reduce RPM & Feed Rates (IPM) by 30-50% to prevent tool breakage due to extremely small diameter (D). Bits are not guaranteed due to extremely small diameter.
