Royce Ayr 1-Flute Downcut "O" Flute Carbide - 1/4"
Single-Flute O-Flute Downcut
Hard-Plastic Router Bit
Solid-carbide, right-hand O-flute downcut router bit designed for routing hard plastics. Its 1/4-inch cutting diameter, 3/4-inch cutting edge, 1/4-inch shank, and 2-1/2-inch overall length provide a balanced format for profiling, slotting, trimming, and CNC nesting applications where downward cutting force can assist material hold-down.
Main Product Description
The Royce Ayr Single-Flute O-Flute Hard-Plastic Downcut Router Bit R62-71405 is engineered for routing hard plastics in compatible CNC systems. Its 0.2500-inch cutting diameter and 0.750-inch cutting edge provide a practical configuration for profiling, slotting, trimming, nesting, and controlled material removal in suitable rigid-plastic applications.
The single-flute O-flute geometry provides generous chip space, while the downcut form directs cutting force toward the work surface to assist material hold-down. This can support workpiece stability during routing when the tool is used with appropriate feeds, speeds, workholding, and chip extraction.
The 0.250-inch shank and 2.500-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, plastic compatibility, and chip extraction.
Best Fit Applications
Product Highlights
Downcut Material Control
The downcut design directs cutting force toward the work surface to assist material hold-down during compatible routing operations.
Single-Flute O-Flute Geometry
The generous flute space supports controlled chip formation while routing suitable hard-plastic materials.
Balanced 1/4-Inch Tool Format
The 1/4-inch diameter and shank with a 3/4-inch cutting edge suit profiling, slotting, trimming, and nesting work.
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 2-1/2-inch (63.5 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, hard-plastic compatibility, and chip extraction according to the machine and approved shop procedures.
Improve Hard-Plastic Material Control
The Royce Ayr Single-Flute O-Flute Hard-Plastic Downcut Router Bit R62-71405 provides a solid-carbide solution for routing hard plastics. Its 1/4-inch diameter, 3/4-inch cutting edge, 1/4-inch shank, single-flute geometry, and 2-1/2-inch overall length support profiling, slotting, trimming, nesting, and production routing.
The downcut design assists material hold-down when the tool is correctly held and operated within suitable hard-plastic machining parameters.
