Royce Ayr 2-Flute Downcut Spiral Router Bit 3/8 in (9.53 mm)
2-Flute Downcut Spiral
Router Bit
Solid-carbide downcut spiral router bit designed for clean top-edge CNC routing in solid wood, wood composites, laminated materials, melamine, and selected plastics. Its 3/8-inch cutting diameter, 1-inch cutting edge, matching 3/8-inch shank, and 3-inch overall length support dados, grooves, profiles, panel routing, and production machining where visible-surface quality matters.
Main Product Description
The Royce Ayr 2-Flute Downcut Spiral Router Bit R57-32222 is designed for general-purpose routing where clean top-edge quality is important. Its downcut spiral geometry directs cutting pressure toward the workpiece, helping control top-surface breakout during dadoes, grooves, panel routing, trimming, and profile work.
The 3/8-inch cutting diameter, 1-inch cutting edge, matching 3/8-inch shank, and 3-inch overall length provide a balanced format for compatible CNC router and routing-machine setups. The tool is suited to solid wood, wood composites, laminated material, melamine, and selected plastics where controlled downcut action is preferred.
This solid-carbide tool uses two downcut spiral flutes. Rotation and coating are not specified by the supplied source and must be confirmed before ordering or programming. Correct collet condition, minimum practical projection, verified runout, suitable RPM, feed rate, depth-per-pass, workholding, and dust or chip evacuation are essential for maintaining surface quality and reliable tool life.
Best Fit Applications
Product Highlights
Downcut Top-Surface Control
The downcut spiral directs cutting pressure toward the workpiece to help control upper-surface breakout in laminate, melamine, and wood-based panels.
Balanced 3/8-Inch Format
The matching cutting diameter and shank suit compatible CNC router setups requiring a stable general-purpose downcut configuration.
Panel & Groove Routing
The 1-inch cutting edge supports dados, grooves, trimming, profiles, and panel-processing operations where top-edge quality matters.
Compatibility & Installation Notes
Confirm that the spindle, collet, and toolholder accept an exact 3/8-inch (9.53 mm) shank and provide adequate clearance for the 3-inch overall length and required projection. Rotation and coating are not specified by the supplied source, so verify those details before ordering, programming, or installation. Inspect and clean the collet, minimize unsupported projection, verify runout, and match spindle speed, feed rate, cut depth, workholding, guarding, and dust or chip evacuation to the selected material.
