Metric 5 mm Cutting Diameter
Royce Ayr identifies this exact metric-diameter configuration for grain-matching nested applications where narrow routing geometry is required.


HW/carbide two-flute right-hand mortise-compression router bit for CNC routing laminated or veneered wood and wood composites where both top and bottom finish are critical. Its metric 5 mm cutting diameter, 7/8-inch cutting edge, 0.220-inch upcut section, 1/4-inch shank, and 3-inch overall length suit grain-matching nested applications and chip-free dado routing.
Two-flute HW/carbide compression geometry with right-hand rotation. Upward and downward shearing action helps prevent laminate chipping on both faces while the short upcut supports chip-free dado routing.
Designed for compatible CNC routers using precision 1/4-inch collets or approved 1/4-inch toolholding systems, including grain-matching nested panel applications.
The Royce Ayr R60-12064 is a two-flute mortise-compression router bit for laminated or veneered wood and wood composites where top and bottom finish is critical. Royce Ayr's current series table specifies a 5 mm cutting diameter, 0.875-inch cutting edge, 0.220-inch upcut length, 0.250-inch shank, two flutes, right-hand rotation, and a 3.000-inch overall length.
Compression geometry combines upward and downward shearing action so both panel faces are supported during routing. Royce Ayr specifies this action to help prevent chipping of laminates, while the short upcut section allows chip-free dado routing in compatible laminated and veneered panel applications.
Royce Ayr's Precision CNC Tooling catalogue identifies this exact 5 mm diameter version for grain-matching nested applications. The current series lists coating type None and places the family within Solid Carbide Tooling. Correct collet condition, runout, tool projection, spindle speed, feed rate, pass depth, entry strategy, workholding, and extraction remain essential for repeatable production.
Technical Specifications
Royce Ayr identifies this exact metric-diameter configuration for grain-matching nested applications where narrow routing geometry is required.
Upward and downward shearing action supports both panel faces and helps prevent laminate chipping when top and bottom finish are critical.
The 0.220-inch upcut section supports chip-free dado routing while preserving the verified 7/8-inch cutting edge and 1/4-inch shank configuration.
Confirm that the CNC router toolholder accepts the exact 1/4-inch (6.35 mm) shank and provides suitable clearance for the 3-inch overall tool length. Verify right-hand spindle rotation, inspect the collet and nut, minimize unsupported projection, check 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.
Royce Ayr R60-12064 combines a 5 mm diameter, 7/8-inch cutting edge, 0.220-inch upcut section, 1/4-inch shank, two-flute right-hand compression geometry, coating None, and a 3-inch overall length.
Its compression shear protects top and bottom laminate faces while the short upcut supports chip-free dado work, making this metric-diameter tool a focused fit for grain-matching nested CNC applications.
