Top-Surface Downcut Action
Downcut geometry directs cutting force toward the work surface to support cleaner top edges in laminated and veneered materials.


Solid-carbide, right-hand combination downcut router bit engineered for laminated or veneered wood and wood composites where top-surface finish is critical. Its 1/2-inch cutting diameter, 1-5/8-inch cutting edge, 1/2-inch shank, four-flute geometry, and 4-inch overall length support high-quality production routing with a combined roughing and finishing action.
This four-flute solid-carbide tool combines roughing and finishing geometry with downcut action to support cleaner top surfaces in laminated or veneered wood and compatible wood-composite materials.
Designed for compatible CNC routers using a precision 1/2-inch (12.7 mm) collet or approved toolholding system with sufficient clearance for the 4-inch overall length.
The Royce Ayr Quadruple-Flute Combination Downcut Router Bit R60-71102 is designed for routing laminated or veneered wood and wood composites when top-surface finish is critical. Its downcut action directs cutting force toward the work surface, helping control top-edge breakout during compatible profiling, sizing, and production-routing operations.
The four-flute combination geometry integrates roughing and finishing action in one tool. This configuration is intended to support faster production feed rates while maintaining a refined top finish, provided the machine, workholding, spindle power, and cutting parameters are suitable for the application.
The 0.5000-inch cutting diameter, 1.625-inch cutting edge, 0.500-inch shank, and 4.000-inch overall length require a compatible precision collet or approved toolholder. Before machining, verify collet condition, runout, right-hand spindle rotation, tool projection, spindle speed, feed rate, depth per pass, workholding, and chip extraction.
Technical Specifications
Downcut geometry directs cutting force toward the work surface to support cleaner top edges in laminated and veneered materials.
The four-flute combination design integrates roughing and finishing action in one tool for efficient production machining.
The 1/2-inch diameter and shank, 1-5/8-inch cutting edge, and 4-inch overall length suit compatible industrial CNC routing systems.
Confirm that the CNC router spindle or toolholder accepts an exact 1/2-inch (12.7 mm) shank and provides sufficient clearance for the 4-inch (101.6 mm) overall length. Inspect the collet and nut, minimize unsupported tool projection, verify right-hand rotation and runout, and establish spindle speed, feed rate, depth per pass, workholding, and chip extraction for the laminated, veneered, or composite material being machined.
The Royce Ayr Quadruple-Flute Combination Downcut Router Bit R60-71102 provides a four-flute solid-carbide solution for routing laminated or veneered wood and wood composites where the visible top surface requires controlled edge quality.
Its combination rougher-finisher geometry and downcut action support productive CNC machining when the tool is correctly held and operated within suitable feed, speed, workholding, and chip-extraction parameters.
