Main Product Description
The Royce Ayr 2-Flute Downcut Spiral Router Bit R57-22209 is a general-purpose tool designed for clean top-edge cutting in wood and wood-based sheet goods. Its downcut spiral geometry directs cutting pressure toward the workpiece, helping reduce top-surface chipping during dados, grooves, profiles, and laminated-material details.
With a 0.1875-inch cutting diameter, 0.750-inch cutting edge, 0.250-inch shank, and 2.500-inch overall length, the tool is suited to cabinet shops, millwork operations, router-table work, and CNC applications requiring a controlled small-diameter downcut configuration.
Royce Ayr lists this series for solid wood, wood composites, laminated materials, and selected plastics. Correct collet condition, tool projection, spindle direction, RPM, feed rate, depth-per-pass, material support, and chip evacuation are essential for maintaining edge quality, dimensional accuracy, and service life.

Product Highlights
Compact 3/16-Inch Diameter
The small cutting diameter supports detailed grooves, profiles, and controlled routing where narrow feature sizes are required.
HW Carbide Construction
The solid-carbide cutting body supports rigidity, cutting-edge retention, and repeatable dimensions in compatible production applications.
Compatibility & Installation Notes
Confirm that the router, spindle, and toolholder accept an exact 1/4-inch (6.35 mm) shank and provide suitable clearance for the 3/16-inch cutting diameter. Inspect and clean the collet, collet nut, and tool shank, minimize unsupported projection, verify runout, and confirm spindle direction before machining. Establish RPM, feed rate, plunge method, and depth-per-pass for the selected wood, laminate, composite, or plastic material.
Improve Small-Diameter Top-Edge Quality
The Royce Ayr 2-Flute Downcut Spiral Router Bit R57-22209 provides a compact HW solid-carbide solution for detailed routing in solid wood, wood composites, laminated materials, and selected plastics.
Its 3/16-inch diameter, 3/4-inch cutting edge, 1/4-inch shank, two downcut flutes, and 2-1/2-inch overall length support clean top-edge machining when correctly held and operated within suitable cutting parameters.
