Ultimax Coating
The coating is specified for reduced friction, increased edge hardness, good adhesion, and extended tool life in nested-routing applications.


Ultimax-coated solid-carbide compression spiral router bit for CNC routing laminated or veneered wood and wood composites where clean top and bottom edges are critical. Its 3/8-inch cutting diameter, 7/8-inch cutting edge, 1/2-inch upcut length, and 3-inch overall length suit compact nested-routing applications.
This production-grade compression tool combines solid-carbide construction, two-flute spiral geometry, right-hand rotation, and an Ultimax coating for nested CNC routing where edge quality, friction control, and tool life matter.
Designed for compatible CNC routers using precision 3/8-inch collets or approved toolholding systems for laminated, veneered, and composite panel processing.
The Royce Ayr 2-Flute Ultimax Compression Spiral Router Bit R60-11401UM is part of the Double Flute Compression series and is designed for CNC routing laminated or veneered wood and wood composites when clean top and bottom edge quality is important. Its compression geometry combines upward and downward shearing action to help reduce chipping on laminated faces.
The 0.3750-inch cutting diameter, 0.875-inch cutting edge, and 0.500-inch upcut length provide a compact configuration for nested routing and sheet-good production. The 0.375-inch shank and 3.000-inch overall length suit compatible CNC router toolholding systems that require a rigid 3/8-inch compression tool.
Royce Ayr specifies the Ultimax coating for reduced friction, increased edge hardness, good coating adhesion, and extended tool life in nested-routing applications. Correct collet condition, tool projection, spindle speed, feed rate, cutting depth, ramp strategy, and workholding remain essential for maintaining edge quality and service life.
Technical Specifications
The coating is specified for reduced friction, increased edge hardness, good adhesion, and extended tool life in nested-routing applications.
Upward and downward shearing action helps reduce chipping on laminated or veneered panel faces where both edges matter.
The 3/8-inch diameter, 7/8-inch cutting edge, 1/2-inch upcut length, and 3-inch overall length suit compact CNC compression-routing work.
Confirm that the CNC router spindle, collet, and toolholder accept an exact 3/8-inch (9.53 mm) shank. Verify right-hand rotation, collet condition, tool projection, runout, RPM, feed speed, cutting depth, plunge or ramp strategy, clearance, guarding, dust extraction, and workholding before machining. Confirm that the 1/2-inch (12.7 mm) upcut section is appropriate for the panel thickness and required compression transition.
The Royce Ayr 2-Flute Ultimax Compression Spiral Router Bit R60-11401UM provides a coated solid-carbide solution for laminated, veneered, and composite panel production. Its 3/8-inch cutting diameter, 7/8-inch cutting edge, 1/2-inch upcut length, and 3-inch overall length support compact CNC routing applications.
Compression spiral geometry helps control chipping on both panel faces, while the Ultimax coating supports reduced friction, increased edge hardness, and longer service life when the tool is correctly held and operated within suitable machining parameters.
