Ultimax Coating
Royce Ayr specifies Ultimax to minimize friction, increase edge hardness, provide excellent adhesion, and support exceptional tool life in nested-routing applications.


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 1/4-inch cutting diameter, 7/8-inch cutting edge, 0.200-inch upcut section, 1/4-inch shank, and 2-1/2-inch overall length combine compression shear with Royce Ayr's Ultimax coating for nested-routing production.
Two-flute right-hand compression geometry with Ultimax coating. Upward and downward shearing action is designed to control 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 for nested routing, profiling, and compatible dado operations.
The Royce Ayr R60-12001UM is an Ultimax-coated two-flute mortise-compression router bit in the current Double Flute Mortise Compression series. Royce Ayr's current official series table lists a 0.2500-inch cutting diameter, 0.875-inch cutting edge, 0.200-inch upcut length, 0.250-inch shank, two flutes, right-hand rotation, 2.500-inch overall length, and Ultimax coating.
Royce Ayr specifies this family for laminated or veneered wood and wood composites where top and bottom finish are critical. Upward and downward shearing action helps prevent chipping of laminates, while the short upcut allows chip-free dado routing in compatible panel applications.
Royce Ayr's Ultimax documentation 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. Correct collet condition, runout, projection, spindle speed, feed rate, pass depth, entry strategy, workholding, and extraction remain essential for production use.
Technical Specifications
Royce Ayr specifies Ultimax to minimize friction, increase edge hardness, provide excellent adhesion, and support exceptional tool life in nested-routing applications.
Upward and downward shearing action supports both panel faces and helps prevent laminate chipping where top and bottom finish are critical.
The verified 0.200-inch upcut section supports chip-free dado routing while preserving the exact 7/8-inch cutting edge configuration.
Confirm that the CNC router toolholder accepts the exact 1/4-inch (6.35 mm) shank and provides suitable clearance for the 2-1/2-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 R60-12001UM combines a 1/4-inch cutting diameter, 7/8-inch cutting edge, 0.200-inch upcut section, 1/4-inch shank, two-flute right-hand mortise-compression geometry, Ultimax coating, and a 2-1/2-inch overall length.
Its opposing shear action protects top and bottom laminate faces, the short upcut supports chip-free dado work, and Ultimax targets friction reduction, edge hardness, adhesion, and tool life in nested CNC routing.
