Compact 3/8-Inch Format
The 3/8-inch cutting diameter and shank suit compatible CNC routing work requiring a smaller compression tool.


A compact solid-carbide right-hand compression spiral router bit for CNC routing laminated, veneered, and wood-composite panels where controlled top and bottom edge quality is required. Its 3/8-inch cutting diameter and shank, 1-1/4-inch cutting edge, 0.400-inch upcut section, and 3-inch overall length suit compatible panel-processing applications.
This compact production tool combines solid-carbide construction, two compression flutes, and right-hand rotation to help control chipping on both faces of compatible laminated, veneered, and composite panels.
Designed for compatible CNC routers using precision 3/8-inch collets or approved toolholding systems. Match the 0.400-inch upcut section and 1-1/4-inch cutting edge to the panel thickness and programmed cutting depth.
The Royce Ayr 2-Flute Compression Spiral Router Bit R60-11415 is designed for CNC routing where both the top and bottom faces of the panel require a clean finish. Its compression geometry combines upward and downward shearing action to help reduce chipping in compatible laminated, veneered, and wood-composite materials.
The tool features a 0.3750-inch cutting diameter, 1.250-inch cutting edge, 0.400-inch upcut section, 0.375-inch shank, two flutes, right-hand rotation, no coating, and a 3.000-inch overall length. This compact configuration suits compatible cabinet-component, nested-routing, and panel-processing applications requiring a smaller compression tool.
The 0.400-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 for maintaining finish quality and tool life.
Technical Specifications
The 3/8-inch cutting diameter and shank suit compatible CNC routing work requiring a smaller compression tool.
The 1-1/4-inch cutting edge provides a compact production-routing reach for compatible panel materials.
The 0.400-inch upcut section should be matched carefully to panel thickness and programmed cutting depth.
Confirm that the CNC router spindle, collet, and toolholder accept an exact 3/8-inch (9.53 mm) shank. Verify right-hand rotation, tool projection, runout, available clearance, guarding, dust extraction, hold-down, RPM, feed rate, pass strategy, and material thickness before machining. Position the 0.400-inch upcut section and remaining downcut geometry correctly for the intended routing operation.
The Royce Ayr 2-Flute Compression Spiral Router Bit R60-11415 provides a solid-carbide solution for CNC routing laminated, veneered, and composite panels where clean top and bottom edge quality is required. Its 3/8-inch diameter and shank, 1-1/4-inch cutting edge, 0.400-inch upcut section, and 3-inch overall length support compact production-routing applications.
Two-flute compression geometry and right-hand rotation support controlled panel machining when the tool is correctly held, positioned through the material, and operated within suitable machining parameters.
