Neutral Axial Geometry
Straight-flute cutting action minimizes upward or downward thrust compared with spiral geometries during controlled routing passes.


Solid-carbide right-hand straight-flute router bit designed for general-purpose machining in solid wood, softwood, MDF, core panels, and compatible plastics. Its 1/2-inch cutting diameter, 1-inch cutting edge, 1/2-inch shank, and 3-inch overall length support accurate routing, grooving, slotting, and dado production.
This production-grade tool combines a rigid solid-carbide body, two straight cutting flutes, and right-hand rotation for stable general-purpose routing in compatible CNC and overhead-shaper systems.
Designed for compatible CNC routers and heavy overhead shapers using precision 1/2-inch collets or approved toolholding systems.
The Royce Ayr 2-Flute Straight General-Purpose Router Bit R56-11814 is engineered for production routing in solid wood, softwood, MDF, core panels, and compatible plastics. Its 0.5000-inch cutting diameter and 1.000-inch cutting edge provide a balanced configuration for profiling, grooving, slotting, dado work, and cabinet-component machining.
The straight dual-flute geometry applies neutral axial force compared with upcut or downcut spirals, helping reduce workpiece lifting during controlled passes. A rigid 0.500-inch solid-carbide body supports parallel sidewall tracking and helps limit deflection when machining deeper channels.
The 3.000-inch overall length and right-hand rotation are suited to compatible CNC routers and industrial overhead shapers. Correct collet condition, tool projection, spindle speed, feed rate, and depth-per-pass are essential for maintaining concentricity, cutting quality, and service life.
Technical Specifications
Straight-flute cutting action minimizes upward or downward thrust compared with spiral geometries during controlled routing passes.
The solid-carbide body helps control side deflection and supports accurate vertical tracking in slots, grooves, and dado channels.
Solid-carbide construction supports cutting-edge retention and thermal stability in demanding wood and panel-processing cycles.
Confirm that the spindle, router, or overhead-shaper toolholder accepts an exact 1/2-inch (12.7 mm) shank. Inspect the collet and nut for wear or contamination, minimize unsupported tool projection, and verify runout before machining. Establish spindle speed, feed rate, and depth-per-pass according to the material, machine power, and workholding conditions.
The Royce Ayr 2-Flute Straight General-Purpose Router Bit R56-11814 provides a rigid solid-carbide solution for cabinet, furniture, panel, and architectural-millwork production. Its 1/2-inch diameter, 1-inch cutting edge, 1/2-inch shank, and 3-inch overall length support repeatable routing across a broad range of common shop materials.
Balanced two-flute cutting action and right-hand rotation help maintain clean sidewalls, controlled chip formation, and consistent dimensions when the tool is correctly held and operated within suitable machining parameters.
