1/4-Inch Cutting Format
The 1/4-inch cutting diameter and shank suit compatible smaller-profile compression-routing work.


A compact solid-carbide two-flute compression spiral router bit for CNC routing laminated, veneered, and wood-composite panels where controlled top and bottom edge quality is required. Its 1/4-inch cutting diameter and shank, 7/8-inch cutting edge, 1/2-inch upcut section, and 2-1/2-inch overall length suit compatible small-diameter production-routing applications.
This compact production tool combines solid-carbide construction and two compression flutes to help control chipping on both faces of compatible laminated, veneered, and composite panels.
Designed for compatible CNC routers using precision 1/4-inch collets or approved toolholding systems. Match the 1/2-inch upcut section and 7/8-inch cutting edge to the panel thickness and programmed cutting depth.
The Royce Ayr 2-Flute Compression Spiral Router Bit R60-11409 is designed for clean CNC routing in laminated panels, veneered wood, and compatible wood-composite materials. Its compression geometry combines upward and downward shearing action to help reduce chipping on both faces of the workpiece.
The tool features a 0.2500-inch cutting diameter, 0.875-inch cutting edge, 0.500-inch upcut section, 0.250-inch shank, two flutes, no coating, and a 2.500-inch overall length. This compact format suits compatible cabinet, millwork, nested-routing, and smaller-profile panel-processing applications.
The 1/2-inch upcut section must be positioned correctly for the material thickness and programmed depth so the compression transition engages the workpiece as intended. Rotation is not specified in the supplied source and should be confirmed before production use. Correct collet condition, tool projection, spindle speed, feed rate, hold-down, and dust extraction remain essential.
Technical Specifications
The 1/4-inch cutting diameter and shank suit compatible smaller-profile compression-routing work.
The compression geometry helps reduce chipping on both faces of compatible laminated and veneered panel materials.
The 1/2-inch upcut section should be positioned correctly within the material thickness and programmed cutting depth.
Confirm that the CNC router spindle, collet, and toolholder accept an exact 1/4-inch (6.35 mm) shank. Verify the required rotation direction, tool projection, runout, available clearance, guarding, dust extraction, hold-down, RPM, feed rate, pass strategy, and material thickness before machining. Position the 1/2-inch upcut section and remaining downcut geometry correctly for the intended routing operation.
The Royce Ayr 2-Flute Compression Spiral Router Bit R60-11409 provides a solid-carbide solution for CNC routing laminated, veneered, and composite panels where clean top and bottom edge quality is required. Its 1/4-inch diameter and shank, 7/8-inch cutting edge, 1/2-inch upcut section, and 2-1/2-inch overall length support compact production-routing applications.
Two-flute compression geometry supports controlled panel machining when the tool is correctly held, positioned through the material, and operated within suitable machining parameters.
