Royce Ayr 2-Flute Ballnose Solid Carbide Router Bit - 1/4" Dia x 7/8" Cut
2-Flute
Upcut Ballnose
Router Bit
Solid-carbide, two-flute upcut ballnose router bit designed for general-purpose machining in solid wood and wood composites. Its 1/4-inch cutting diameter, 7/8-inch cutting edge, 1/4-inch shank, and 2-1/2-inch overall length support profiling, carving, contouring, and three-dimensional routing with effective chip evacuation.
Main Product Description
The Royce Ayr 2-Flute Upcut Ballnose Router Bit R52-23405 is a general-purpose solid-carbide tool for solid wood and wood composites. Its 0.2500-inch cutting diameter and 0.875-inch cutting edge provide a compact, rigid configuration for profiling, carving, relief work, and three-dimensional contour machining.
The two-flute upcut spiral lifts chips away from the cutting path to support effective chip evacuation, while the ballnose profile produces rounded contact geometry suited to carving and smooth contour transitions. The combination is appropriate for profiling and sculpting applications where both material removal and surface continuity matter.
The 0.250-inch shank and 2.500-inch overall length are intended for compatible precision collets and toolholders. Correct collet condition, tool projection, spindle speed, feed rate, and depth-per-pass are essential for maintaining concentricity, cutting quality, and tool life.
Best Fit Applications
Product Highlights
Upcut Chip Evacuation
Two upcut spiral flutes lift chips away from the cutting path, helping keep carving and profiling passes clear.
Ballnose Profiling Geometry
The rounded cutting profile supports smooth contour transitions, relief carving, sculpting, and three-dimensional surface work.
Solid-Carbide Construction
HW solid-carbide construction provides a rigid cutting body for accurate machining in solid wood and wood composites.
Compatibility & Installation Notes
Confirm that the spindle or router toolholder accepts an exact 1/4-inch (6.35 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, step-over, and depth-per-pass according to the material, machine power, workholding, and required finish.
Improve Carving and Contour Accuracy
The Royce Ayr 2-Flute Upcut Ballnose Router Bit R52-23405 provides a compact solid-carbide solution for carving, profiling, and three-dimensional routing in solid wood and wood composites. Its 1/4-inch diameter, 7/8-inch cutting edge, 1/4-inch shank, and 2-1/2-inch overall length support controlled machining across a range of CNC carving applications.
Two upcut flutes support chip evacuation, while the ballnose profile creates rounded cutting contact for smooth contours and relief work when the tool is correctly held and operated within suitable machining parameters.
