Extended 3-Inch Cutting Edge
The 3-inch cutting edge and 6-inch overall length provide extended reach for compatible larger-format CNC routing operations.


Large-format solid-carbide compression spiral router bit for laminated or veneered wood and wood composites where top and bottom finish is critical. Its 3/4-inch cutting diameter, 3-inch cutting edge, 0.890-inch upcut section, 3/4-inch shank, and 6-inch overall length provide extended reach for compatible CNC routing systems.
This two-flute solid-carbide tool combines upward and downward shearing action to support clean routing on both faces of compatible laminated, veneered, and wood-composite panels.
Designed for compatible CNC routers using a precision 3/4-inch (19.05 mm) collet or approved toolholding system. The 0.890-inch upcut section must be positioned correctly within the material for the intended compression effect.
The Royce Ayr 2-Flute Compression Spiral Router Bit R60-11419 belongs to Royce Ayr's Double Flute Compression series. It is intended for routing laminated or veneered wood and wood composites when finished top and bottom edges are important.
Its compression geometry combines upward and downward cutting action to prevent chipping on laminated faces. The 0.890-inch (22.606 mm) upcut section must be matched to the material thickness and programmed cut depth so the compression transition remains correctly positioned within the workpiece.
The 0.7500-inch cutting diameter, 3.000-inch cutting edge, 0.750-inch shank, and 6.000-inch overall length require rigid, low-runout toolholding and adequate machine clearance. Before machining, verify collet condition, right-hand rotation, tool projection, spindle speed, feed rate, pass depth, workholding, and chip extraction.
Technical Specifications
The 3-inch cutting edge and 6-inch overall length provide extended reach for compatible larger-format CNC routing operations.
The 3/4-inch shank requires compatible industrial CNC toolholding with suitable rigidity, clearance, and low runout.
The 0.890-inch upcut section must be matched carefully to material thickness and programmed cutting depth.
Confirm that the CNC router spindle or toolholder accepts an exact 3/4-inch (19.05 mm) shank and provides sufficient clearance for the 6-inch (152.4 mm) overall length. Inspect the collet and nut, minimize unsupported projection, verify right-hand rotation and runout, and establish suitable spindle speed, feed rate, pass depth, workholding, and chip extraction. Position the 0.890-inch (22.606 mm) upcut section and compression transition correctly within the material.
The Royce Ayr 2-Flute Compression Spiral Router Bit R60-11419 provides a solid-carbide solution for laminated, veneered, and wood-composite routing where top and bottom finish is critical.
Its 3/4-inch diameter and shank, 3-inch cutting edge, 0.890-inch upcut section, two-flute compression geometry, and 6-inch overall length suit compatible CNC systems when correctly held and operated.
