Main Product Description
The Royce Ayr 2-Flute Downcut Spiral Router Bit R57-22211 is part of the R57-222/322 downcut spiral family. It is designed for general-purpose routing in solid wood, wood composites, laminated materials, and selected plastics where a clean top edge is a priority.
The downcut spiral geometry directs cutting pressure toward the workpiece, helping reduce top-surface chipping during grooves, dados, shallow pockets, profiles, and panel-machining operations. Its 0.2188-inch cutting diameter and 1.000-inch cutting edge provide a narrow cutting configuration for detailed routing work.
The 0.250-inch shank and 2.500-inch overall length suit compatible CNC routers and router-based production equipment. Correct collet condition, minimum practical projection, verified runout, suitable spindle direction, RPM, feed rate, cutting depth, workholding, and chip evacuation are essential for maintaining finish quality and tool life.

Product Highlights
Narrow 7/32-Inch Diameter
The compact cutting diameter and 1-inch cutting edge support detailed grooves, dados, profiles, and controlled routing passes.
HW Carbide Construction
The solid-carbide 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. Inspect and clean the collet, collet nut, and tool shank, minimize unsupported projection, verify runout, and confirm spindle direction before machining. Match RPM, feed speed, plunge method, and cutting depth to the selected material, and maintain effective chip evacuation because downcut geometry can pack chips in deeper grooves.
Improve Narrow Top-Edge Routing
The Royce Ayr 2-Flute Downcut Spiral Router Bit R57-22211 provides a compact HW solid-carbide solution for detailed routing in solid wood, wood composites, laminated materials, and selected plastics.
Its 7/32-inch diameter, 1-inch cutting edge, 1/4-inch shank, and 2-1/2-inch overall length support clean top-edge machining when correctly held and operated within suitable cutting parameters.
