Upcut Chip Evacuation
The upcut spiral moves chips upward and away from the cutting zone, supporting efficient 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 3/4-inch cutting diameter, 3-1/8-inch cutting edge, 3/4-inch shank, and 6-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 3/4-inch collets or approved 3/4-inch toolholding systems with sufficient clearance for the 6-inch overall tool length.
The Royce Ayr R60-32108 is a three-flute upcut chipbreaker finisher for general-purpose routing in solid wood and wood composites. The verified configuration uses a 0.750-inch cutting diameter, 3.125-inch cutting edge, 0.750-inch shank, three flutes, and a 6.000-inch overall length.
Royce Ayr specifies the upcut spiral for strong chip evacuation during CNC routing. Integrated chipbreaker geometry helps interrupt the chip and reduce furring and tear-out, supporting cleaner machining in compatible solid-wood and composite-panel applications.
This family is listed by Royce under Solid Carbide Tooling. The long 3-1/8-inch cutting edge and 6-inch overall length create an extended-reach configuration, so rigid toolholding, minimized runout, correct feed and spindle speed, controlled depth of cut, secure workholding, and effective extraction are especially important.
Technical Specifications
The upcut spiral moves chips upward and away from the cutting zone, supporting efficient 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 3/4-inch diameter, 3-1/8-inch cutting edge, 3/4-inch shank, and 6-inch overall length match the exact R60-32108 configuration.
Confirm that the CNC router toolholder accepts the exact 3/4-inch (19.05 mm) shank and provides sufficient clearance for the 6-inch overall tool length. Because this is an extended-reach configuration, inspect the collet and nut, minimize unsupported projection where possible, 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 manufacturer sources used for this SKU do not publish those fields.
Royce Ayr R60-32108 combines a 3/4-inch diameter, 3-1/8-inch cutting edge, 3/4-inch shank, three-flute upcut geometry, and 6-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 long-reach solid-carbide tool a clear role in compatible production routing where both reach and finish quality matter.
