Royce Ayr Solid Carbide Fiberglass Burr - 1/4" Dia x 3/4" Cut x 1/4" Shank
Fiberglass Rougher/Finisher
Burr Router Bit
Solid-carbide, right-hand burr-style router bit designed for fiberglass and other reinforced plastic materials. Its 1/4-inch cutting diameter, 3/4-inch cutting edge, 1/4-inch shank, and 2-1/2-inch overall length combine with a freely cutting fluted-burr form that supports higher feed rates in compatible CNC routing applications.
Main Product Description
The Royce Ayr Fiberglass Rougher/Finisher Burr Router Bit R67-02602 is developed for routing fiberglass and other reinforced plastic materials. Its 0.2500-inch cutting diameter and 0.750-inch cutting edge provide a compact format for trimming, profiling, slotting, and controlled material removal in abrasive composite-sheet applications.
Royce Ayr identifies this model as a fiberglass rougher/finisher tool. The fluted burr-style cutting form is designed to cut more freely and enable higher feed rates than a conventional burr geometry when the tool is matched to suitable spindle speed, feed rate, workholding, and extraction.
The 0.250-inch shank and 2.500-inch overall length require a compatible precision collet or approved toolholder. Before production, verify collet condition, runout, right-hand spindle rotation, tool projection, spindle speed, feed rate, depth per pass, workholding, material suitability, and chip or dust extraction.

Product Highlights
Freely Cutting Burr Geometry
The fluted burr-style form is designed to cut more freely in fiberglass and reinforced plastics than a conventional burr configuration.
Rougher/Finisher Format
The tool combines productive material removal with finishing capability for compatible trimming, profiling, and routing operations.
Compact 1/4-Inch Tool Format
The 1/4-inch diameter and shank, 3/4-inch cutting edge, and 2-1/2-inch overall length suit detailed composite-routing setups.
Compatibility & Installation Notes
Confirm that the CNC router spindle or toolholder accepts an exact 1/4-inch (6.35 mm) shank and provides sufficient clearance for the 2-1/2-inch (63.5 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, material suitability, and chip or dust extraction according to the machine and approved shop procedures.
Improve Reinforced-Plastic Routing
The Royce Ayr Fiberglass Rougher/Finisher Burr Router Bit R67-02602 provides a solid-carbide solution for routing fiberglass and other reinforced plastic materials. Its 1/4-inch diameter, 3/4-inch cutting edge, 1/4-inch shank, and 2-1/2-inch overall length support trimming, profiling, slotting, and controlled CNC material removal.
The fluted rougher/finisher burr geometry supports freer cutting and productive feed capability when the tool is correctly held and operated within suitable machining parameters.
