2-Flute Ultimax Downcut
Spiral Router Bit
Ultimax-coated solid-carbide downcut spiral router bit designed for clean top-edge CNC routing in solid wood, wood composites, laminated materials, MDF, plywood, and selected plastics. Its 1/2-inch cutting diameter, 1-1/8-inch cutting edge, matching 1/2-inch shank, and 3-inch overall length support dados, grooves, pockets, profiles, cabinet parts, and panel-processing work.
Main Product Description
The Royce Ayr 2-Flute Ultimax Downcut Spiral Router Bit R57-32229UM is designed for CNC routing and general-purpose machining in woodworking and panel-processing environments. Its downcut spiral geometry directs cutting pressure toward the workpiece, helping support the top surface during dados, grooves, pockets, and profiles in laminated and wood-based materials.
The 1/2-inch cutting diameter, 1-1/8-inch cutting edge, matching 1/2-inch shank, and 3-inch overall length provide a standard industrial format for compatible CNC router collets and toolholders. The UM suffix identifies this SKU as the Ultimax-coated version of the Royce Ayr downcut spiral series.
This solid-carbide tool uses two downcut spiral flutes and is suited to cabinet parts, casework, fixtures, furniture components, laminated panels, MDF, plywood, solid wood, and selected plastics. Rotation, RPM or feed data, and country of origin are not specified for this exact SKU in the supplied source and should be confirmed before programming or ordering when required.

Product Highlights
Ultimax-Coated Version
The UM suffix identifies this SKU as the Ultimax-coated version of the Royce Ayr 1/2-inch downcut spiral format.
Clean Top-Edge Downcut

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. Rotation and RPM or feed data are not specified by the supplied source, so verify those details before programming or installation. Inspect and clean the collet, minimize unsupported projection, verify runout, and match feeds, speeds, cutting depth, workholding, guarding, and chip or dust evacuation to the selected material.
