Amana Tool 47222-S Miniature Flush Trim Plunge Bit, Carbide Tipped, 3/16 Dia, 1/4 Shank

Overview

The Amana Tool 47222-S is a carbide-tipped miniature flush trim plunge bit designed for delicate, high-precision pattern routing. Its compact upper bearing guides edge work on small parts, making it well suited for sign detailing, guitar work, and intricate toy projects where control matters.

Small bearing, big potential

With a 3/16" diameter upper ball bearing, this bit’s guide is notably smaller than many ball-bearing router bits on the market. That allows you to navigate tight contours and fine profiles with extra finesse, helping you achieve clean edges on delicate materials.

• Diameter: 3/16"
• Cutting height: 1/4"
• Shank: 1/4"
• Overall length: 1-3/4"
• Replacement bearing: 47775

What you can route

This bit is ideal for template or pattern routing of parts, joints, and internal cuts. It behaves as a plunge-cutting straight bit with a shank-mounted pilot, allowing the edge of a template to guide the cut and form a close duplicate of the pattern.

It supports both handheld and table-mounted routers. When the pattern is on top (handheld) or beneath (table), the bearing follows the template edge to translate the design into a precise workpiece.

How you use it

In practice, you can flush-trim profiles, route around tight corners, and work in confined areas where space is limited. The bit’s two-flute design encourages controlled, clean passes across a range of materials.
