Upcut Chip Evacuation
The upward cutting direction helps move chips away from the cut during compatible hard-plastic and aluminum routing operations.


Solid-carbide, right-hand upcut router bit engineered for CNC routing in hard plastics and aluminum. Its 1/8-inch cutting diameter, 1/2-inch cutting edge, 1/4-inch shank, and 2-inch overall length combine Z2 geometry with upward chip evacuation for compact sign-making, clad-panel, and precision routing applications.
Two-flute solid-carbide right-hand upcut tooling developed for hard plastics and aluminum, with upward chip evacuation for compatible CNC routing applications.
Designed for compatible CNC routers using precision 1/4-inch collets or approved 1/4-inch toolholding systems.
The Royce Ayr Aluminum and Hard Plastic Upcut Router Bit R52-02401 is a two-flute solid-carbide CNC router tool developed for hard plastics and aluminum. The published configuration uses a 0.1250-inch cutting diameter, 0.500-inch cutting edge, 0.250-inch shank, two flutes, right-hand rotation, and a 2.000-inch overall length.
Upcut geometry carries chips upward and away from the machining zone, helping reduce chip recutting and supporting controlled evacuation in suitable aluminum and hard-plastic routing operations. The compact 1/8-inch diameter is suited to detailed CNC work where smaller features or tighter radii are required.
Royce Ayr lists this family for CNC Router applications in sign making and clad paneling. Correct collet condition, minimized tool projection, verified runout, secure workholding, and properly established spindle speed, feed rate, pass depth, lubrication or cooling strategy where required, and chip extraction are essential for safe, repeatable performance.
Technical Specifications
The upward cutting direction helps move chips away from the cut during compatible hard-plastic and aluminum routing operations.
Z2 solid-carbide construction provides two cutting edges in a production-oriented geometry specifically listed for hard plastics and aluminum.
The 1/8-inch cutting diameter, 1/2-inch cutting edge, 1/4-inch shank, and 2-inch overall length match the exact R52-02401 specification.
Confirm that the CNC router toolholder accepts the exact 1/4-inch (6.35 mm) shank and accommodates the 2-inch overall tool length with suitable clearance. Inspect the collet and nut, minimize unsupported projection, verify runout, secure the workpiece, and establish spindle speed, feed rate, depth-per-pass, lubrication or cooling where appropriate, and chip extraction for the specific aluminum or hard-plastic material being machined.
Royce Ayr R52-02401 combines a 1/8-inch diameter, 1/2-inch cutting edge, 1/4-inch shank, two right-hand flutes, and 2-inch overall length for CNC routing in hard plastics and aluminum.
The solid-carbide construction and upward chip evacuation make this compact configuration suited to detailed sign-making, clad-panel, and compatible production routing when matched to correct toolholding and cutting parameters.
