Royce Ayr Solid Carbide Edge Rounding Router Bit - 1/4" Dia x 3/8" Cut x 1/4" Shank x 1/8" Radius
2-Flute Edge Rounding
Router Bit
Solid-carbide, right-hand straight-flute edge-rounding router bit designed for applying a 1/8-inch radius to plastic edges in point-of-purchase display production. Its 1/4-inch cutting diameter, 3/8-inch cutting edge, 1/4-inch shank, and 2-1/2-inch overall length provide a compact format for controlled profiling in compatible CNC routing systems.
Main Product Description
The Royce Ayr 2-Flute Straight Edge-Rounding Router Bit R66-02201 is designed for the point-of-purchase display industry and for applying a controlled radius to the edge of compatible plastic materials. Its 0.2500-inch cutting diameter, 0.375-inch cutting edge, and 0.125-inch profile radius provide a compact format for edge softening and decorative plastic profiling.
Royce Ayr specifies a straight standard flute design intended to provide a more resilient cutting edge. The two-flute configuration supports balanced cutting engagement when the tool is matched to suitable spindle speed, feed rate, pass depth, workholding, and 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, machine clearance, workholding, and the suitability of the plastic being machined.
Best Fit Applications
Product Highlights
1/8-Inch Edge Radius
The 0.125-inch profile radius applies a consistent rounded edge to compatible plastic components and display parts.
Resilient Straight-Flute Design
Royce Ayr specifies a straight standard flute form intended to provide a more resilient cutting edge in plastic-routing applications.
Compact 1/4-Inch Tool Format
The matching 1/4-inch cutting diameter and shank support secure precision toolholding for controlled edge-profiling operations.
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 and finished 1/8-inch radius. Inspect the collet and nut, minimize unsupported tool projection, verify right-hand rotation and runout, and establish spindle speed, feed rate, pass depth, workholding, and extraction according to the plastic material, machine, and approved shop procedures.
Improve Plastic Edge-Rounding Consistency
The Royce Ayr 2-Flute Straight Edge-Rounding Router Bit R66-02201 provides a solid-carbide solution for applying a controlled 1/8-inch radius to plastic edges. Its 1/4-inch diameter, 3/8-inch cutting edge, 1/4-inch shank, and 2-1/2-inch overall length support compact edge-profiling operations in point-of-purchase display manufacturing.
Two-flute straight cutting geometry and right-hand rotation support repeatable edge rounding when the tool is correctly held and operated within suitable plastic-machining parameters.
