Longer Cutting Reach
The 1-3/8-inch cutting edge and 3-1/2-inch overall length provide added reach for compatible CNC panel-routing operations.


Two-flute mortise compression router bit for laminated or veneered wood and wood composites where top and bottom finish is critical. Its 1/2-inch cutting diameter, 1-3/8-inch cutting edge, 0.250-inch upcut section, 1/2-inch shank, and 3-1/2-inch overall length provide added reach for compatible CNC panel-routing operations.
This two-flute solid-carbide tool combines upward and downward shearing action with a short upcut section to support clean routing on both faces of compatible laminated and veneered panels.
Designed for compatible CNC routers using a precision 1/2-inch (12.7 mm) collet or approved toolholding system. The 0.250-inch upcut section must be positioned correctly within the material for the intended compression effect.
The Royce Ayr 2-Flute Mortise Compression Router Bit R60-12004-3.5 belongs to Royce Ayr's Double Flute Mortise 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 short 0.250-inch (6.35 mm) upcut section supports compatible dado-routing operations when the cutting depth and entry strategy place the compression transition correctly within the workpiece.
The 0.5000-inch cutting diameter, 1.375-inch cutting edge, 0.500-inch shank, and 3.500-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 1-3/8-inch cutting edge and 3-1/2-inch overall length provide added reach for compatible CNC panel-routing operations.
The 0.250-inch upcut section supports chip-conscious dado routing when the compression transition is positioned correctly.
The 1/2-inch shank suits compatible precision CNC collets and approved toolholders using this common production size.
Confirm that the CNC router spindle or toolholder accepts an exact 1/2-inch (12.7 mm) shank and provides sufficient clearance for the 3-1/2-inch (88.9 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 0.250-inch (6.35 mm) upcut section and compression transition correctly within the material.
The Royce Ayr 2-Flute Mortise Compression Router Bit R60-12004-3.5 provides a solid-carbide solution for laminated, veneered, and wood-composite panel routing where top and bottom finish is critical.
Its 1/2-inch diameter and shank, 1-3/8-inch cutting edge, 0.250-inch upcut section, two-flute compression geometry, and 3-1/2-inch overall length suit compatible CNC systems when correctly held and operated.
