Ultimax Coating
Royce Ayr specifies the coating for reduced friction, increased edge hardness, strong adhesion, and extended tool life in nested routing.


Ultimax-coated triple-flute compression router bit for laminated or veneered wood and wood composites where top and bottom finish is critical. Its 1/2-inch cutting diameter, 1-1/8-inch cutting edge, 3/8-inch upcut section, 1/2-inch shank, and 3-inch overall length suit compatible nested CNC routing systems.
This three-flute solid-carbide tool combines upward and downward shearing action to support clean routing on both faces of compatible laminated, veneered, and wood-composite panels.
Designed for compatible CNC routers using a precision 1/2-inch (12.7 mm) collet or approved toolholding system. The 3/8-inch upcut section must be positioned correctly within the material for the intended compression effect.
The Royce Ayr 3-Flute Ultimax Compression Router Bit R60-11502UM belongs to Royce Ayr's Triple Flute 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 0.375-inch (9.525 mm) upcut section supports chip-free dado routing when the cutting depth and entry strategy position the compression transition correctly within the workpiece.
Royce Ayr specifies Ultimax coating for reduced friction, increased edge hardness, strong coating adhesion, and extended tool life in nested-routing applications. Before machining, verify toolholding, runout, right-hand rotation, tool projection, spindle speed, feed rate, pass depth, workholding, and chip extraction.
Technical Specifications
Royce Ayr specifies the coating for reduced friction, increased edge hardness, strong adhesion, and extended tool life in nested routing.
The three-flute compression geometry provides a production-focused option where controlled top and bottom edge finish is required.
The 3/8-inch upcut section supports chip-free dado routing when the compression transition is positioned correctly.
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-inch (76.2 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 0.375-inch (9.525 mm) upcut section and compression transition correctly within the material.
The Royce Ayr 3-Flute Ultimax Compression Router Bit R60-11502UM provides an Ultimax-coated 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, 1-1/8-inch cutting edge, 3/8-inch upcut section, triple-flute compression geometry, Ultimax coating, and 3-inch overall length suit compatible CNC systems when correctly held and operated.
