Amana 45366-3US PLUNGE 3/4 DIA UPPER BB 1/2SHK

This bit is essentially a plunge-cutting straight with a shank-mounted ball-bearing pilot. Versatile, useful for template/pattern routing of parts, joints, internal cuts and 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.

Up-Shear Angle – The shear angle cuts faster, cleaner and lasts longer than straight angle because of the chip removal speed.

We recommend using shear angle in most instances especially where large diameters are used.
