Top & Bottom Edge Control
Opposing upward and downward shearing action is engineered to help prevent chipping on both faces of laminated and veneered panels.


Right-hand double-flute compression tooling for routing laminated or veneered wood and wood composites when clean top and bottom edges are critical. Its 3/4-inch cutting diameter, 2-1/2-inch cutting edge, 1-1/4-inch upcut section, 3/4-inch shank, and 5-inch overall length combine opposing shear directions for production CNC panel routing.
Two-flute compression geometry combines upward and downward shearing action to help prevent chipping on both faces of laminated, veneered, and wood-composite panels in compatible CNC routing applications.
Designed for compatible CNC routers using precision 3/4-inch collets or approved 3/4-inch toolholding systems.
The Royce Ayr R60-11408 is a two-flute compression router bit for laminated or veneered wood and wood composites where top and bottom finish is critical. Its opposing upward and downward shearing action is designed to reduce laminate chipping on both panel faces during compatible CNC routing operations.
The published configuration uses a 0.7500-inch cutting diameter, 2.500-inch cutting edge, 1.250-inch upcut length, 0.750-inch shank, two flutes, right-hand rotation, and a 5.000-inch overall length. Correct vertical engagement of the compression geometry is important so the intended upcut and downcut zones support the required edge finish.
Royce Ayr lists R60-11408 under its Solid Carbide Tooling / Double-Flute Compression family with material code HW and coating type None. The family is specified for CNC routers and is associated with window and door, moulding and millwork, and stairs and railings production.
Technical Specifications
Opposing upward and downward shearing action is engineered to help prevent chipping on both faces of laminated and veneered panels.
The published 1.250-inch upcut section defines the lower compression zone and must be correctly engaged for the intended top and bottom edge control.
The 3/4-inch diameter, 2-1/2-inch cutting edge, 3/4-inch shank, and 5-inch overall length match the exact R60-11408 specification.
Confirm that the CNC router toolholder accepts the exact 3/4-inch (19.05 mm) shank and provides suitable clearance for the 5-inch overall tool length. Program entry and cutting depth so the workpiece is engaged by the intended upcut and downcut zones; incorrect vertical engagement can compromise the top or bottom finish. Inspect the collet and nut, minimize unsupported projection, verify runout, secure the panel, and establish spindle speed, feed rate, pass depth, and dust extraction for the actual laminate, veneer, and core construction.
Royce Ayr R60-11408 combines a 3/4-inch diameter, 2-1/2-inch cutting edge, 1-1/4-inch upcut section, 3/4-inch shank, two right-hand flutes, and 5-inch overall length for laminated, veneered, and wood-composite CNC routing.
The double-flute compression geometry applies opposing shear directions to help protect top and bottom surfaces, making this configuration a fit for compatible CNC production where finish quality on both panel faces is critical.
