Infinity Tools 1/4" Shank Straight Router Bit w/ Plunge Point & Top Bearing

The Infinity Tools 1/4" Shank Straight Router Bit with Plunge Point & Top Bearing is a versatile pattern bit built for clean, accurate template routing. The bearing mounts above the cutter on the shank, so you can place your template below the workpiece and see exactly what you're cutting. The plunge-cutting point lets you drop the bit straight into the middle of a workpiece to start interior cuts without burning. It's an essential addition to any pattern and flush-trim router bit kit.

How a top-bearing pattern bit works

With the bearing riding on top of the cutter, the bit follows a template attached beneath your stock. This top-bearing configuration is ideal for table-routing duplicate parts, signs, and curved or irregular shapes. For the cleanest results and longer bit life, rough-cut your workpiece about 1/8" larger than the template, then make the final pass with the bearing tracking the pattern.

Plunge point for interior cuts

Unlike a standard pattern bit, the plunge point lets you start cuts in the center of a panel — perfect for mortises, inlays, and cutouts — without scorching the material. You can run the bit with or without the bearing for added versatility.
