Royce Ayr 3-Flute Low Helix Up-Cut Solid Carbide Router Bit - 1/4" Dia x 7/8" 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 1/4-inch cutting diameter, 7/8-inch cutting edge, 1/4-inch shank, three-flute geometry, and 3-inch overall length provide a compact format with upward chip evacuation.
Main Product Description
The Royce Ayr 3-Flute Upcut Low Helix Finisher Router Bit R60-22502 belongs to Royce Ayr's Low Helix Finisher Upcut series. The manufacturer specifies this series 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 in compatible applications. The three-flute format is suited to production finishing when spindle speed, feed rate, and chip load are correctly matched.
The 0.2500-inch cutting diameter, 0.875-inch cutting edge, 0.250-inch shank, and 3.000-inch overall length require a compatible precision collet or approved toolholder. Before machining, verify collet condition, runout, right-hand spindle rotation, tool projection, spindle speed, feed rate, depth per pass, workholding, and chip extraction for the material being processed.
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.
Compact 1/4-Inch Tool Format
The 1/4-inch diameter and shank, 7/8-inch cutting edge, and 3-inch overall length suit compatible CNC systems.
Compatibility & Installation Notes
Confirm that the CNC router spindle or toolholder accepts an exact 1/4-inch (6.35 mm) shank and provides sufficient clearance for the 3-inch (76.2 mm) overall length. Inspect the collet and nut, minimize unsupported projection, verify right-hand rotation and runout, and establish suitable spindle speed, feed rate, depth per pass, workholding, and chip extraction for the material being machined.
Control Finish Quality with Compact Upcut Geometry
The Royce Ayr 3-Flute Upcut Low Helix Finisher Router Bit R60-22502 provides a solid-carbide solution for routing plastics and composites and for finish passes in solid wood.
Its 1/4-inch diameter and shank, 7/8-inch cutting edge, three-flute low-helix geometry, and 3-inch overall length suit compatible CNC systems when the tool is correctly held and operated within appropriate machining parameters.
