Royce Ayr 2-Flute Downcut Spiral Router Bit 1/2 in (12.7 mm)
2-Flute Downcut Spiral
Router Bit
Solid-carbide downcut spiral router bit designed for clean top-edge routing in solid wood, wood composites, laminated materials, and selected plastics. Its 1/2-inch cutting diameter, extended 2-1/8-inch cutting length, 1/2-inch shank, and 4-inch overall length support deeper grooves, dados, profiles, and panel-processing work.
Main Product Description
The Royce Ayr 2-Flute Downcut Spiral Router Bit R57-32235 is designed for routing applications where the top edge of the workpiece needs to remain clean during machining. Its downcut spiral geometry directs cutting pressure toward the surface, helping reduce top-edge chipping in laminated panels, wood composites, and finished materials.
The 0.500-inch cutting diameter and extended 2.125-inch cutting length support deeper grooves, dados, profiles, and routing passes. Its 0.500-inch shank and 4.000-inch overall length provide a robust configuration for compatible CNC routers and industrial routing systems.
The solid-carbide construction and two-flute geometry support rigidity and repeatable cutting performance in production environments. Correct collet condition, minimum practical projection, verified runout, suitable rotation, 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 top-edge chipping in laminated and finished materials.
Extended 2-1/8-Inch Reach
The long cutting edge supports deeper grooves, dados, profiles, and routing passes where additional cutting length is required.
Rigid Solid-Carbide Body
The one-piece carbide construction and 1/2-inch shank support stability and repeatable dimensions in compatible production setups.
Compatibility & Installation Notes
Confirm that the spindle and toolholder accept an exact 1/2-inch (12.7 mm) shank and provide sufficient clearance for the 4-inch overall length and required projection. Inspect and clean the collet, collet nut, and tool shank, minimize unsupported projection, verify runout, and confirm rotation before machining. Match RPM, feed rate, depth-per-pass, workholding, and chip evacuation to the selected material and machine conditions.
Extend Clean Top-Edge Routing
The Royce Ayr 2-Flute Downcut Spiral Router Bit R57-32235 provides a solid-carbide solution for deeper routing in solid wood, wood composites, laminated materials, and selected plastics.
Its 1/2-inch diameter, 2-1/8-inch cutting length, 1/2-inch shank, and 4-inch overall length support clean top-edge machining when correctly held and operated within suitable cutting parameters.
