System Fit

Designed for compatible CNC routers using a precision 3/8-inch (9.525 mm) collet or approved toolholding assembly with sufficient clearance for the 3-inch overall length.

Main Product Description

The Royce Ayr 3-Flute Low-Helix Upcut Phenolic Spiral Router Bit R72-10004 is engineered for routing phenolic and other fiber-reinforced plastics. Its 0.3750-inch cutting diameter and 0.875-inch cutting edge provide a compact production format for profiling, slotting, trimming, and controlled material removal in composite-sheet applications.

The three-flute low-helix upcut geometry supports chip evacuation while maintaining stable cutting engagement. Royce Ayr specifies unique chip-breakers that help reduce harmonics during routing when the tool is matched to suitable spindle speed, feed rate, and workholding.

The 0.375-inch shank and 3.000-inch overall length require a compatible precision collet or approved toolholder. Before production, verify collet condition, runout, right-hand spindle rotation, tool projection, spindle speed, feed rate, depth per pass, workholding, material suitability, and chip extraction.

Performance Details

Product Highlights

01

Chip-Breaker Harmonic Control

Specialized chip-breaker geometry is intended to help reduce harmonics during routing of phenolic and fiber-reinforced plastic materials.

02

Three-Flute Low-Helix Geometry

The three-flute low-helix upcut form balances controlled cutting engagement with upward chip evacuation in compatible CNC applications.

03

Compact 3/8-Inch Tool Format

The matching 3/8-inch cutting diameter and shank support secure precision toolholding for detailed composite-sheet routing.

Before Machining

Compatibility & Installation Notes

Confirm that the CNC router spindle or toolholder accepts an exact 3/8-inch (9.525 mm) shank and provides sufficient clearance for the 3-inch (76.2 mm) overall length. Inspect the collet and nut, minimize unsupported tool projection, verify right-hand rotation and runout, and establish spindle speed, feed rate, depth per pass, workholding, material suitability, and chip extraction according to the machine and approved shop procedures.

Production Outcome

Improve Phenolic Routing Stability

The Royce Ayr 3-Flute Low-Helix Upcut Phenolic Spiral Router Bit R72-10004 provides a solid-carbide solution for routing phenolic and other fiber-reinforced plastics. Its 3/8-inch diameter, 7/8-inch cutting edge, 3/8-inch shank, three-flute geometry, and 3-inch overall length support profiling, slotting, trimming, and production routing.

Low-helix upcut geometry supports chip evacuation, while the specialized chip-breakers help control harmonics when the tool is correctly held and operated within suitable machining parameters.
