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, melamine-style panels, laminated sheet goods, and selected plastics. Its 3/8-inch cutting diameter, 1-1/4-inch cutting length, 1/2-inch shank, and 3-inch overall length support profile routing, trimming, pocketing, through-cutting, and panel-production work.
Main Product Description
The Royce Ayr 2-Flute Downcut Spiral Router Bit R57-32227 is part of the R57-222/322 downcut spiral family and is intended for shops requiring clean top-edge routing in solid wood, wood composites, melamine-style panels, laminated sheet goods, and selected plastics. Its downcut geometry directs cutting pressure toward the workpiece, helping support the upper surface during routing.
The 3/8-inch cutting diameter and 1-1/4-inch cutting length provide a practical format for profiles, trimming, pockets, grooves, and compatible through-cutting operations. The larger 1/2-inch shank and 3-inch overall length suit properly matched CNC router collets and toolholders where rigidity, projection, clearance, and programmed depth are correctly controlled.
This solid-carbide tool uses two downcut spiral flutes. Coating, rotation, and RPM or feed limits are not specified by the supplied source and should be confirmed before ordering or programming when those details are required. Correct collet condition, minimum practical projection, verified runout, suitable feeds and speeds, depth-per-pass, workholding, and dust or chip evacuation are essential for reliable performance.
Best Fit Applications
Product Highlights
Downcut Top-Edge Control
The downcut spiral directs cutting pressure into the workpiece to help support cleaner upper edges during compatible routing operations.
Rigid 1/2-Inch Shank
The larger shank supports compatible holder setups where rigidity, collet fit, and controlled tool projection are priorities.
Panel Production Format
The 3/8-inch diameter and 1-1/4-inch cutting length suit cabinet parts, fixture components, profiles, pockets, and panel-processing work.
Compatibility & Installation Notes
Confirm that the spindle, collet, 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. Coating, rotation, and RPM or feed limits 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 feeds, speeds, cutting depth, workholding, guarding, and dust or chip evacuation to the selected material.
