Royce Ayr 2-Flute Straight Solid Carbide Router Bit - 1/2" Diameter x 1" Cut
2-Flute Downcut Spiral
Router Bit
General-purpose solid-carbide downcut spiral router bit designed for clean top-edge CNC routing in solid wood, wood composites, laminated materials, and selected plastics. Its 1/2-inch cutting diameter, 1-1/8-inch cutting edge, 1/2-inch shank, and 3-inch overall length support dados, grooves, profiles, and production routing where upper-surface finish matters.
Main Product Description
The Royce Ayr 2-Flute Downcut Spiral Router Bit R57-32229 is designed for general-purpose CNC routing in solid wood, wood composites, laminated materials, and selected plastics. Its downcut spiral geometry directs cutting pressure toward the workpiece, helping control the top edge during dados, grooves, profiles, and panel-machining operations.
The 0.5000-inch cutting diameter and 1.125-inch cutting edge provide a versatile format for cabinet, casegoods, millwork, and general production routing. The matching 0.500-inch shank supports a rigid machine interface in compatible CNC router collets and toolholding systems.
The solid-carbide construction and two-flute geometry support repeatable cutting performance when properly applied. Correct collet condition, minimum practical projection, verified runout, suitable spindle direction, RPM, feed rate, depth-per-pass, workholding, and chip evacuation are essential for maintaining finish quality and tool life.
Best Fit Applications
Product Highlights
Clean Top-Edge Downcut
The downcut spiral directs cutting pressure toward the workpiece to help reduce upper-edge lifting in laminated and finished materials.
Versatile 1/2-Inch Format
The 1/2-inch cutting diameter and matching shank provide a stable configuration for common production-routing operations.
1-1/8-Inch Cutting Edge
The verified cutting edge supports controlled dados, grooves, profiles, and routing passes in compatible wood-based materials.
Compatibility & Installation Notes
Confirm that the spindle and toolholder accept an exact 1/2-inch (12.7 mm) shank and provide adequate clearance for the 3-inch overall length and required projection. Inspect and clean the collet, collet nut, and tool shank, minimize unsupported projection, verify runout, and confirm spindle direction before machining. Match RPM, feed rate, depth-per-pass, workholding, and chip evacuation to the selected material and machine conditions.
Improve Clean Top-Edge Routing
The Royce Ayr 2-Flute Downcut Spiral Router Bit R57-32229 provides a solid-carbide solution for general-purpose CNC routing in solid wood, wood composites, laminated materials, and selected plastics.
Its 1/2-inch diameter, 1-1/8-inch cutting edge, 1/2-inch shank, two-flute geometry, and 3-inch overall length support controlled production machining when correctly held and operated within suitable cutting parameters.
