Upcut Chip Evacuation
The upcut spiral moves chips upward and away from the cutting zone, supporting effective evacuation in compatible CNC wood-routing operations.


Solid-carbide three-flute upcut chipbreaker finisher for general-purpose CNC routing in solid wood and wood composites. Its 1/2-inch cutting diameter, 1-3/8-inch cutting edge, 1/2-inch shank, and 3-1/2-inch overall length combine upward chip evacuation with chipbreaker geometry that helps reduce furring and tear-out.
Three-flute solid-carbide spiral tooling that combines upcut chip evacuation with chipbreaker geometry for general-purpose routing in solid wood and wood composites.
Designed for compatible CNC routers using precision 1/2-inch collets or approved 1/2-inch toolholding systems.
The Royce Ayr R60-32103 is a three-flute upcut chipbreaker finisher for general-purpose routing in solid wood and wood composites. The verified configuration uses a 0.500-inch cutting diameter, 1.375-inch cutting edge, 0.500-inch shank, three flutes, and a 3.500-inch overall length.
The upcut spiral is designed to move chips upward and away from the cutting zone, helping maintain effective evacuation during compatible CNC routing. Integrated chipbreaker geometry helps interrupt the chip and reduce furring and tear-out, supporting cleaner machining in solid wood and composite-panel applications.
This R60-321 configuration uses a 1/2-inch shank and 3-1/2-inch overall length, providing a practical production format for routing, profiling, and edge-machining operations where controlled chip evacuation and improved finish quality are required.
Technical Specifications
The upcut spiral moves chips upward and away from the cutting zone, supporting effective evacuation in compatible CNC wood-routing operations.
Royce Ayr specifies chipbreakers to help reduce furring and tear-out while the three-flute configuration provides a finishing-oriented cutting profile.
The 1/2-inch diameter, 1-3/8-inch cutting edge, 1/2-inch shank, and 3-1/2-inch overall length match the exact R60-32103 specification.
Confirm that the CNC router toolholder accepts the exact 1/2-inch (12.70 mm) shank and provides suitable clearance for the 3-1/2-inch overall tool length. Inspect the collet and nut, minimize unsupported projection, verify runout, secure the workpiece, and establish spindle speed, feed rate, pass depth, and extraction for the actual wood or composite material. Rotation and coating are intentionally not stated because the verified sources used for this exact SKU do not publish those fields.
Royce Ayr R60-32103 combines a 1/2-inch diameter, 1-3/8-inch cutting edge, 1/2-inch shank, three-flute upcut geometry, and 3-1/2-inch overall length for CNC routing in solid wood and wood composites.
The upcut spiral supports chip evacuation while the chipbreaker profile helps control furring and tear-out, giving this solid-carbide tool a clear production role where routing efficiency and finish quality both matter.
