Royce Ayr Solid Carbide Low Helix Up Cut Router Bit - 1/2" Dia x 1-5/8" Cut
3-Flute Upcut Low Helix
Finisher Router Bit
Solid-carbide low-helix upcut finisher for routing plastics and composites and for finish passes in solid wood. Its 1/2-inch cutting diameter, 1-5/8-inch cutting edge, 1/2-inch shank, three-flute geometry, and verified 4-inch overall length support controlled finishing with upward chip evacuation.
Main Product Description
The Royce Ayr 3-Flute Upcut Low Helix Finisher Router Bit R60-22509 is part of Royce Ayr's Low Helix Finisher Upcut series. It is intended for routing plastics and composites and for finish passes in solid wood.
The upcut flute direction moves chips upward from the cut, while the low-helix finishing geometry supports controlled material engagement and surface quality in compatible applications. The three-flute format is suited to production finishing when feed rate, spindle speed, and chip load are correctly matched.
The 0.5000-inch cutting diameter, 1.625-inch cutting edge, 0.500-inch shank, and verified 4.000-inch overall length require rigid, low-runout toolholding and adequate machine clearance. Before machining, verify collet condition, right-hand spindle rotation, tool projection, feed rate, spindle speed, depth per pass, workholding, and chip extraction.
Best Fit Applications
Product Highlights
Low-Helix Finishing Geometry
Low-helix flute geometry supports controlled finishing passes in compatible plastics, composites, and solid wood.
Upcut Chip Direction
Upcut action directs chips upward from the cutting path to support evacuation during CNC routing operations.
Verified 4-Inch Tool Format
The 1-5/8-inch cutting edge and 4-inch overall length match the official R60-22509 configuration.
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 4-inch (101.6 mm) overall length. Use rigid, low-runout toolholding, minimize unsupported projection where possible, verify right-hand rotation, and establish suitable spindle speed, feed rate, depth per pass, workholding, and chip extraction for the material being machined.
Control Finish Quality with Low-Helix Upcut Geometry
The Royce Ayr 3-Flute Upcut Low Helix Finisher Router Bit R60-22509 provides a solid-carbide solution for routing plastics and composites and for finish passes in solid wood.
Its 1/2-inch diameter and shank, 1-5/8-inch cutting edge, three-flute low-helix geometry, and verified 4-inch overall length suit compatible CNC systems when the tool is correctly held and operated within appropriate machining parameters.
