Royce Ayr 2-Flute Straight Solid Carbide Router Bit – 1/2" Diameter x 1" Cut Length


Double O-Flute
Router Bit
Two-flute solid-carbide O-flute router bit engineered for clean,free-cutting machining in soft plastics. Its 1/2-inch cutting diameter,1-inch cutting edge,1/2-inch shank,and 4-inch overall length provide extended reach for routing,profiling,slotting,and component trimming in compatible CNC systems.
Main Product Description
The Royce Ayr Double O-Flute General Plastics Router Bit R56-61415 is designed for routing soft plastics where controlled chip formation and clean edge quality are required. Its 0.5000-inch cutting diameter and 1.000-inch cutting edge support profiling,slotting,trimming,and component machining in compatible CNC routing systems.
The double O-flute geometry provides a free-cutting action that helps form and evacuate plastic chips while limiting unnecessary heat buildup. Two cutting edges distribute the machining load and support a smoother finish than comparable single-flute configurations when feed rate,spindle speed,and engagement are correctly matched to the material.
The 0.500-inch shank and 4.000-inch overall length provide additional reach for suitable applications. Correct collet condition,minimum practical tool projection,verified runout,appropriate chip load,and effective chip extraction are essential for controlling heat,avoiding material re-welding,and maintaining tool life.

Best Fit Applications
Product Highlights
Free-Cutting O-Flute Geometry
The open O-flute profile supports controlled chip formation and efficient cutting in compatible soft-plastic materials.
Two-Flute Finish Capability
Dual cutting edges distribute the machining load and support smoother edge quality when operated at suitable chip loads.
Extended 4-Inch Reach
The 4-inch overall length provides additional reach while retaining a rigid 1/2-inch solid-carbide shank interface.
Compatibility & Installation Notes
Confirm that the spindle and toolholder accept an exact 1/2-inch (12.7 mm) shank. Minimize unsupported projection,inspect and clean the collet and tool shank,and verify runout before machining. Establish spindle speed,feed rate,chip load,and depth-per-pass for the specific plastic grade,and maintain effective chip extraction to reduce heat buildup and material re-welding.
Improve Soft-Plastic Routing Control
The Royce Ayr Double O-Flute General Plastics Router Bit R56-61415 provides a solid-carbide solution for professional plastic-routing operations. Its 1/2-inch diameter,1-inch cutting edge,1/2-inch shank,and 4-inch overall length support profiling,slotting,trimming,and component production.
Double O-flute geometry helps produce controlled chips and clean edges when the tool is correctly held and operated with suitable spindle speed,feed rate,chip load,and extraction.
