Upcut Chip Evacuation
The spiral cutting direction carries chips upward from the cut, supporting efficient evacuation during compatible CNC routing operations.


HW solid-carbide, right-hand general-purpose upcut spiral router bit for solid wood, wood composites, and some plastics. Its 1/2-inch cutting diameter, 2-1/8-inch cutting edge, 1/2-inch shank, and 4-inch overall length combine Z2 cutting geometry with efficient upward chip evacuation for compatible CNC routing operations.
General-purpose two-flute HW solid-carbide spiral tooling with right-hand rotation and upward cutting geometry for efficient chip evacuation in compatible CNC routing applications.
Designed for compatible CNC routers using precision 1/2-inch collets or approved 1/2-inch toolholding systems.
The Royce Ayr General-Purpose Upcut Spiral Router Bit R52-32833 is a two-flute HW solid-carbide CNC router tool for machining solid wood, wood composites, and some plastics. Its 0.5000-inch cutting diameter and 2.125-inch cutting edge provide extended cutting reach while retaining a standard 0.500-inch shank.
Upcut spiral geometry moves chips upward and away from the cutting zone, supporting effective chip evacuation during routing. The Z2 configuration balances cutting engagement and chip space for general-purpose CNC operations where clean evacuation and repeatable sidewall control are required.
The published configuration uses right-hand rotation, a 4.000-inch overall length, and no coating. Correct 1/2-inch collet condition, controlled tool projection, verified runout, suitable spindle speed, feed rate, depth-per-pass, workholding, and dust extraction are essential for consistent machining performance.
Technical Specifications
The spiral cutting direction carries chips upward from the cut, supporting efficient evacuation during compatible CNC routing operations.
Z2 solid-carbide geometry balances cutting engagement and chip space for routing solid wood, wood composites, and some plastics.
The 1/2-inch cutting diameter, 2-1/8-inch cutting edge, 1/2-inch shank, and 4-inch overall length match the exact R52-32833 specification.
Confirm that the CNC router toolholder accepts the exact 1/2-inch (12.70 mm) shank and accommodates the 4-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, and depth-per-pass for the material and machine conditions. Maintain effective chip and dust extraction, particularly when using the upcut geometry for deeper routing passes.
Royce Ayr R52-32833 combines a 1/2-inch diameter, 2-1/8-inch cutting edge, 1/2-inch shank, and 4-inch overall length with two right-hand upcut spiral flutes for general-purpose CNC routing.
The HW solid-carbide construction and upward spiral geometry provide a practical production configuration for solid wood, wood composites, and compatible plastics when matched to proper toolholding, feeds, speeds, workholding, and extraction.
