Main Product Description
The Royce Ayr R60-31001 is a two-flute downcut chipbreaker finisher for general-purpose routing in solid wood and wood composites. The exact current manufacturer specification is a 0.3750-inch cutting diameter, 1.125-inch cutting edge, 0.375-inch shank, two flutes, right-hand rotation, and a 3.000-inch overall length.
Royce Ayr specifies the downcut design to give a clean edge when cutting a dado in laminated material. The downward cutting action helps control the top surface while the integrated chipbreakers help reduce furring and tear-out through the wood or wood-composite core.
This exact SKU is listed with coating type None and sits in Royce Ayr's Solid Carbide Tooling category. The compact 3/8-inch shank and 3-inch overall length make it a practical production configuration for routing, dadoing, profiling, and other compatible CNC operations where top-edge finish control is important.

Product Highlights
Chipbreaker Geometry
Integrated chipbreakers help interrupt chips and reduce furring and tear-out in solid wood and wood-composite routing operations.
Compact 3/8-Inch Format
The exact 3/8-inch diameter, 1-1/8-inch cutting edge, 3/8-inch shank, and 3-inch overall length match the current R60-31001 specification.
Compatibility & Installation Notes
Confirm that the CNC router toolholder accepts the exact 3/8-inch (9.525 mm) shank and provides suitable clearance for the 3-inch overall tool length. Verify right-hand spindle rotation, inspect the collet and nut, minimize unsupported projection, check runout, secure the workpiece, and establish spindle speed, feed rate, pass depth, extraction, and cutting direction for the actual solid-wood, composite, or laminated material.
Clean Top Edges for Laminated Dado Routing
Royce Ayr R60-31001 combines a 3/8-inch diameter, 1-1/8-inch cutting edge, 3/8-inch shank, two-flute right-hand downcut geometry, and 3-inch overall length for CNC routing in solid wood and wood composites.
Its downcut action is intended to preserve a clean top edge in laminated dado work, while chipbreaker geometry helps reduce furring and tear-out for controlled production routing.
