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


HW solid-carbide, right-hand upcut router bit engineered for routing hard plastics and aluminum on compatible CNC routers. Its 3/8-inch cutting diameter, 7/8-inch cutting edge, 3/8-inch shank, and 2-1/2-inch overall length combine Z2 geometry with upward chip evacuation for sign-making, clad-panel, and production routing applications.
Two-flute HW solid-carbide right-hand upcut tooling developed for routing hard plastics and aluminum with effective upward chip evacuation in compatible CNC applications.
Designed for compatible CNC routers using precision 3/8-inch collets or approved 3/8-inch toolholding systems.
The Royce Ayr Aluminum and Hard Plastic Upcut Router Bit R52-12410 is a two-flute HW solid-carbide CNC router tool developed for hard plastics and aluminum. The published configuration uses a 0.3750-inch cutting diameter, 0.875-inch cutting edge, 0.375-inch shank, and 2.500-inch overall length.
Upcut cutting 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 Z2 configuration provides two cutting edges for productive CNC machining while maintaining space for chip flow.
R52-12410 uses right-hand rotation and is listed by Royce Ayr 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 HW solid-carbide construction provides two cutting edges in a production-oriented geometry specifically listed for hard plastics and aluminum.
The 3/8-inch cutting diameter, 7/8-inch cutting edge, 3/8-inch shank, and 2-1/2-inch overall length match the exact R52-12410 specification.
Confirm that the CNC router toolholder accepts the exact 3/8-inch (9.525 mm) shank and accommodates the 2-1/2-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 R52-12410 combines a 3/8-inch diameter, 7/8-inch cutting edge, 3/8-inch shank, and 2-1/2-inch overall length with two right-hand upcut cutting edges for CNC routing in hard plastics and aluminum.
The HW solid-carbide construction and upward chip evacuation make this configuration suited to sign-making, clad-panel, and compatible production routing when matched to correct toolholding and cutting parameters.
