Designed for compatible routers and CNC routers using a precision 1/4-inch collet or approved toolholding assembly.
Main Product Description
The Royce Ayr 2-Flute Downcut Spiral Router Bit R57-22200 is designed for clean routing work in woodworking, cabinetmaking, millwork, and panel-processing environments. Its downcut geometry directs cutting action toward the workpiece, helping produce a cleaner top edge in dados, grooves, routed details, laminated stock, and wood-based panels.
The 1/8-inch cutting diameter and 3/4-inch cutting edge length provide a compact format for smaller routed details, narrow grooves, controlled profiles, and precision CNC machining. The 1/4-inch shank and 2-1/2-inch overall length support compatible router and CNC collet systems.
This solid-carbide tool uses two downcut spiral flutes. The supplied source does not specify rotation or coating, so those details should 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 reliable performance.

Product Highlights
Compact 1/8-Inch Cutter
The small cutting diameter and 3/4-inch cutting edge support narrow grooves, detailed profiles, and controlled routing paths.
Solid-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, CNC spindle, collet, and toolholder accept an exact 1/4-inch (6.35 mm) shank and provide adequate clearance for the 2-1/2-inch overall length and required projection. The supplied source does not specify rotation or coating, so verify those details before ordering or programming. Inspect and clean the collet, minimize unsupported projection, verify runout, and match RPM, feed rate, depth-per-pass, workholding, and dust or chip evacuation to the selected material.
