Main Product Description
The Royce Ayr R52-62601 is a two-flute low-helix O-flute upcut router bit for CNC machining soft and hard plastics. The published configuration uses a 0.2500-inch cutting diameter, 0.375-inch cutting edge, 0.250-inch shank, two flutes, and a 2.500-inch overall length.
Royce Ayr specifies an open-flute design that allows free cutting and good chip formation. The low-helix upcut geometry promotes chip movement away from the cutting zone while maintaining the O-flute profile used for plastic-routing applications.
R52-62601 is listed under Royce Ayr Solid Carbide Tooling for CNC Router use, with coating type None. The family is associated with advanced composite materials, sign making, and clad paneling. Correct collet condition, minimized projection, verified runout, suitable spindle speed, feed rate, pass depth, workholding, and chip extraction remain essential for repeatable plastic machining.

Product Highlights
Low-Helix Upcut Evacuation
The low-helix upcut profile supports controlled chip movement away from the cutting zone when routing soft and hard plastics.
Published 1/4-Inch Configuration
The 1/4-inch cutting diameter, 3/8-inch cutting edge, 1/4-inch shank, and 2-1/2-inch overall length match the exact R52-62601 specification.
Compatibility & Installation Notes
Confirm that the CNC router toolholder accepts the exact 1/4-inch (6.35 mm) shank and provides suitable clearance for the 2-1/2-inch overall tool length. Inspect the collet and nut, minimize unsupported projection, verify runout, secure the workpiece, and establish spindle speed, feed rate, depth-per-pass, and chip extraction for the specific plastic being machined. Rotation is intentionally not stated here because the current Royce Ayr manufacturer table does not publish a rotation value for this family.
Controlled O-Flute Routing for Plastics
Royce Ayr R52-62601 combines a 1/4-inch diameter, 3/8-inch cutting edge, 1/4-inch shank, two-flute O-flute geometry, and 2-1/2-inch overall length for CNC routing in soft and hard plastics.
The solid-carbide construction, open-flute profile, and low-helix upcut geometry provide a compact configuration for free cutting and controlled chip formation in compatible plastic-routing applications.
