4-Flute Rougher / Finisher
Royce Ayr specifies a unique rougher/finisher design in one combination-compression tool to minimize tearout in laminated and veneered panel routing.


Solid-carbide four-flute combination-compression router bit for laminated or veneered wood and wood composites where top and bottom finish are critical. The verified R60-61823 configuration combines a 3/4-inch cutting diameter, 2-1/2-inch cutting edge, 1-1/4-inch upcut section, 3/4-inch shank, and 5-inch overall length. Royce Ayr specifies a unique rougher/finisher design to minimize tearout.
Four-flute solid-carbide combination-compression geometry incorporating roughing and finishing action in one tool. Royce Ayr specifies the design for laminated or veneered wood and wood composites where both panel faces matter.
Designed for compatible CNC routing equipment using a precision 3/4-inch toolholding interface. The exact available manufacturer records confirm the geometry and dimensions used on this page.
The Royce Ayr R60-61823 is a four-flute combination-compression router bit in the manufacturer's Solid Carbide Tooling range. Current Royce Ayr product data identifies the family for laminated or veneered wood and wood composites where top and bottom finish are critical, with a unique rougher/finisher design intended to minimize tearout.
The verified SKU dimensions are a 0.7500-inch cutting diameter, 2.500-inch cutting edge, 1.250-inch upcut length, 0.750-inch shank, four flutes, and a 5.000-inch overall length. The extended 2-1/2-inch cutting edge and 5-inch overall format provide the reach required for thicker panel and nested-routing work where this geometry is appropriate.
This page intentionally limits the specification set to values supported by the accessible current Royce Ayr family data and manufacturer catalogue record. Rotation and coating are not added as assumptions. Verify toolholder fit, runout, tool projection, spindle speed, feed rate, pass depth, workholding, and extraction for the actual material stack and production strategy.
Technical Specifications
Royce Ayr specifies a unique rougher/finisher design in one combination-compression tool to minimize tearout in laminated and veneered panel routing.
The verified 1-1/4-inch upcut section is integrated within a 2-1/2-inch cutting edge for the exact R60-61823 configuration.
A 3/4-inch cutting diameter and matching 3/4-inch shank are paired with a 5-inch overall length for substantial CNC routing applications.
Confirm that the CNC router toolholder accepts the exact 3/4-inch (19.05 mm) shank and provides suitable clearance for the 5-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, entry strategy, and extraction for the actual laminated, veneered, or wood-composite panel. Confirm rotation and coating from the physical tool or current Royce Ayr documentation before installation because those fields were not present in the accessible exact SKU record used here.
Royce Ayr R60-61823 combines a 3/4-inch cutting diameter, 2-1/2-inch cutting edge, 1-1/4-inch upcut section, 3/4-inch shank, four-flute combination-compression geometry, and a 5-inch overall length.
Its rougher/finisher design is intended to minimize tearout while routing laminated or veneered wood and wood composites where finish quality on both panel faces is critical.
