Royce Ayr Ultimax Double Flute Compression Spiral Bit 1/2 in (12.7 mm)
2-Flute Ultimax Compression
Spiral Router Bit
An Ultimax-coated solid-carbide compression spiral router bit for CNC routing laminated, veneered, and wood-composite panels where clean top and bottom edges are required. Its 1/2-inch cutting diameter and shank, 1-3/4-inch cutting edge, 3/4-inch upcut section, and 4-inch overall length provide a balanced production-routing format.
Main Product Description
The Royce Ayr 2-Flute Ultimax Compression Spiral Router Bit R60-11413UM is built for CNC routing applications in industrial woodworking, cabinet-component production, millwork, and panel-processing environments. Its compression geometry combines upward and downward shearing action to help reduce chipping on laminated or veneered materials where both faces require a clean finish.
The tool features a 0.5000-inch cutting diameter, 1.750-inch cutting edge, 0.750-inch upcut section, 0.500-inch shank, two flutes, right-hand rotation, Ultimax coating, and a 4.000-inch overall length. This configuration offers a balanced combination of cutting reach, rigidity, and edge control for compatible cabinet, millwork, window-and-door, stair, railing, and panel-processing applications.
The Ultimax coating distinguishes this model from the uncoated tool with otherwise matching primary dimensions. The 3/4-inch upcut section must be positioned correctly for the material thickness and programmed depth so the compression transition engages the workpiece as intended. Correct collet condition, tool projection, spindle speed, feed rate, pass strategy, hold-down, chip evacuation, and dust extraction remain essential.
Best Fit Applications
Product Highlights
Ultimax Coating
This coated version is distinct from the uncoated tool with otherwise matching primary dimensions and production geometry.
Compression Edge Control
Upward and downward shearing action helps reduce chipping on both faces of compatible laminated and veneered panels.
Balanced Production Geometry
The 1-3/4-inch cutting edge and 3/4-inch upcut section suit compatible CNC panel-routing applications.
Compatibility & Installation Notes
Confirm that the CNC router spindle, collet, and toolholder accept an exact 1/2-inch (12.7 mm) shank. Verify right-hand rotation, tool projection, runout, available clearance, guarding, dust extraction, hold-down, RPM, feed rate, ramping strategy, number of passes, and material thickness before machining. Position the 3/4-inch upcut section and remaining downcut geometry correctly for the intended routing operation.
Coated Two-Sided Panel Routing
The Royce Ayr 2-Flute Ultimax Compression Spiral Router Bit R60-11413UM provides a coated solid-carbide solution for CNC routing laminated, veneered, and composite panels where clean top and bottom edge quality is required. Its 1/2-inch diameter and shank, 1-3/4-inch cutting edge, 3/4-inch upcut section, and 4-inch overall length support balanced production-routing applications.
Two-flute compression geometry, right-hand rotation, and the Ultimax coating support controlled panel machining when the tool is correctly held, positioned through the material, and operated within suitable machining parameters.
