Compression Shearing Action
Upward and downward shearing action supports both panel faces and helps prevent laminate chipping when top and bottom finish are critical.


Ultimax-coated 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 1/2-inch cutting diameter, 7/8-inch cutting edge, 0.230-inch upcut section, 1/2-inch shank, and 3-inch overall length combine compression shear with coating technology developed for nested-routing tool life.
Two-flute right-hand compression geometry with Ultimax coating. Upward and downward shearing action is designed to control chipping on both faces of laminated or veneered wood and wood-composite panels, while the short upcut supports chip-free dado routing.
Designed for compatible CNC routers using precision 1/2-inch collets or approved 1/2-inch toolholding systems for nested routing, profiling, and compatible dado operations.
The Royce Ayr R60-12003UM is an Ultimax-coated 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 exact product page lists a 0.5000-inch cutting diameter, 0.875-inch cutting edge, 0.230-inch upcut length, 0.500-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 a chip-free dado to be routed in compatible laminated and veneered panel applications.
Royce Ayr identifies the exact SKU with Ultimax coating and material code HC, while the family is listed within Solid Carbide Tooling. Royce Ayr states that the coating was selected after extensive testing to minimize friction, increase edge hardness, provide excellent adhesion, and deliver exceptional tool life specifically in nested-routing applications.
Technical Specifications
Upward and downward shearing action supports both panel faces and helps prevent laminate chipping when top and bottom finish are critical.
Royce Ayr specifies the 0.230-inch upcut section to support chip-free dado routing while preserving the exact 7/8-inch cutting edge configuration.
Ultimax was selected after extensive coating testing to minimize friction, increase edge hardness, provide excellent adhesion, and extend tool life in nested routing.
Confirm that the CNC router toolholder accepts the exact 1/2-inch (12.70 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 R60-12003UM combines a 1/2-inch diameter, 7/8-inch cutting edge, 0.230-inch upcut section, 1/2-inch shank, two-flute right-hand mortise-compression geometry, Ultimax coating, and a 3-inch overall length.
Its opposing shear action protects top and bottom laminate faces, the short upcut supports chip-free dado work, and the Ultimax coating targets friction reduction, edge hardness, adhesion, and tool life in nested CNC routing.
