Amana tool 45460-3TS Carbide Tipped Flush Trim Plunge Template 1/2 D x 1 CH x 1/4 Inch SHK w Upper Bal Bearing 3 Flute Router Bit

3 Flute Extra strong, new generation of high wear carbide Superior geometric design provides super clean cutsUp Shear and Down-Shear Angles – These shear angles cut faster, cleaner and lasts longer than straight angle because of the chip removal speed. Amana Tool recommends using a shear angle in most instances especially where large diameters are used. These bits are 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 & 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.
