Main Product Description
The Royce Ayr 3-Flute Low-Helix Upcut Router Bit R72-10007 is engineered for routing phenolic and other fiber-reinforced plastics. Its 0.5000-inch cutting diameter and 1.250-inch cutting edge provide a practical production format for profiling, slotting, trimming, and controlled material removal in compatible 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 eliminate harmonics during routing, improving process stability when the tool is matched to suitable spindle speed, feed rate, and workholding.
The 0.500-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 or dust extraction.

Product Highlights
Three-Flute Low-Helix Geometry
The three-flute low-helix upcut form balances controlled cutting engagement with upward chip evacuation in compatible CNC applications.
Rigid 1/2-Inch Tool Format
The matching 1/2-inch cutting diameter and shank support secure precision toolholding and stable routing in properly configured systems.
Compatibility & Installation Notes
Confirm that the CNC router spindle or toolholder accepts an exact 1/2-inch (12.7 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.
Improve Phenolic Routing Stability
The Royce Ayr 3-Flute Low-Helix Upcut Router Bit R72-10007 provides a solid-carbide solution for routing phenolic and other fiber-reinforced plastics. Its 1/2-inch diameter, 1-1/4-inch cutting edge, 1/2-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.
