Main Product Description
The Royce Ayr R52-62604 is a two-flute low-helix O-flute upcut router bit from the solid-carbide precision CNC tooling range. Royce Ayr specifies this geometry for routing both soft and hard plastics, with an open-flute design intended to support free cutting and good chip forming during compatible CNC machining operations.
The tool combines a 0.5000-inch cutting diameter with a 1.125-inch cutting edge, 0.500-inch shank, and 3.500-inch overall length. The right-hand upcut configuration moves formed chips upward from the cutting zone, helping reduce chip recutting when extraction and machining parameters are correctly matched to the plastic being routed.
R52-62604 is supplied without coating and is intended for CNC router applications. Correct collet condition, minimum practical tool projection, verified runout, suitable spindle speed and feed rate, controlled depth-per-pass, secure workholding, and effective chip extraction remain essential to maintain cut quality and avoid excessive heat in thermoplastic materials.

Product Highlights
Low-Helix Upcut Evacuation
The right-hand upcut geometry carries formed chips upward from the cutting zone to support efficient evacuation during CNC routing.
Published 1/2-Inch Configuration
The 1/2-inch diameter, 1-1/8-inch cutting edge, 1/2-inch shank, and 3-1/2-inch overall length match the published R52-62604 configuration.
Compatibility & Installation Notes
Confirm that the CNC router toolholder accepts the exact 1/2-inch (12.70 mm) shank and provides adequate clearance for the 3-1/2-inch overall tool length. Inspect the collet and nut, minimize unsupported projection, verify runout, secure the workpiece, and establish spindle speed, feed rate, and depth-per-pass for the specific plastic. Maintain effective chip extraction and avoid machining conditions that allow chips to recut or heat to build at the cutting edge.
Free-Cutting Plastic Routing with Controlled Chip Formation
Royce Ayr R52-62604 combines low-helix O-flute geometry with a 1/2-inch diameter, 1-1/8-inch cutting edge, 1/2-inch shank, and 3-1/2-inch overall length for CNC routing of soft and hard plastics.
The solid-carbide two-flute upcut configuration is built around free cutting, chip formation, and upward evacuation when matched to proper toolholding, feeds, speeds, workholding, and extraction.
