Designed for compatible CNC routers and router/spindle systems using a precision 1/4-inch collet or approved toolholding assembly.
Main Product Description
The Royce Ayr 2-Flute Downcut Spiral Router Bit R57-22212 is designed for clean top-edge cutting in woodworking, cabinetmaking, millwork, and panel-processing applications. Its downcut geometry directs cutting pressure into the material, helping reduce top-surface tear-out during dados, grooves, pockets, profiles, and routing passes in laminated panels and other wood-based materials.
The 0.2500-inch cutting diameter and 0.813-inch cutting edge provide a practical format for shallow-to-moderate-depth routing operations. The matching 0.250-inch shank and compact 2.500-inch overall length suit compatible CNC router collets and toolholding systems.
This uncoated HW solid-carbide tool uses two downcut spiral flutes. The supplied source does not specify rotation, so spindle direction 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 reliable performance.

Product Highlights
Compact 1/4-Inch Format
The matching 1/4-inch cutting diameter and shank suit common compatible CNC router collets and controlled routing setups.
13/16-Inch Cutting Edge
The verified cutting-edge length supports shallow-to-moderate-depth dados, grooves, pockets, profiles, and panel-routing operations.
Compatibility & Installation Notes
Confirm that the 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, so verify spindle direction before ordering, programming, or installation. 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.
