Efficient Upcut Evacuation
The upward spiral action moves chips away from the cutting zone during slots, grooves, and enclosed routing passes.


General-purpose solid-carbide upcut spiral router bit for solid wood, wood composites, MDF, core panels, and compatible plastics. Its 5/32-inch cutting diameter, 5/8-inch cutting edge, 1/4-inch shank, and 2-inch overall length support efficient chip evacuation in compact CNC routing applications.
This compact production tool combines a solid-carbide body, two right-hand upcut flutes, and a 1/4-inch shank for controlled routing and effective chip evacuation in compatible CNC systems.
Designed for compatible CNC routers and industrial routing equipment using precision 1/4-inch collets or approved toolholding systems.
The Royce Ayr 2-Flute General-Purpose Upcut Spiral Router Bit R52-22804 is designed for routing solid wood, wood composites, MDF, core panels, and compatible plastics. Its 0.1563-inch cutting diameter and 0.625-inch cutting edge provide a compact configuration for grooving, slotting, profiling, and detailed component machining.
The upcut spiral geometry draws chips away from the cutting zone, supporting cleaner flute evacuation during deeper or enclosed cuts. Two cutting flutes provide balanced material removal, while the solid-carbide construction helps maintain rigidity and cutting-edge stability through repeated production cycles.
The 0.250-inch shank and 2.000-inch overall length are intended for compatible precision collets and CNC router spindles. Correct tool projection, collet condition, spindle speed, feed rate, and depth-per-pass are essential for controlling runout, heat generation, finish quality, and tool life.
Technical Specifications
The upward spiral action moves chips away from the cutting zone during slots, grooves, and enclosed routing passes.
The small cutting diameter supports detailed machining, narrow grooves, and compact component features.
The one-piece carbide construction supports cutting-edge stability and controlled deflection in production routing.
Confirm that the spindle and toolholder accept an exact 1/4-inch (6.35 mm) shank. Inspect and clean the collet, collet nut, and shank before installation, minimize unsupported projection, and verify runout before machining. Set spindle speed, feed rate, and depth-per-pass according to the work material, machine power, tool engagement, and workholding conditions.
The Royce Ayr 2-Flute General-Purpose Upcut Spiral Router Bit R52-22804 provides a compact solid-carbide solution for cabinet, furniture, panel, and architectural-millwork production. Its 5/32-inch diameter, 5/8-inch cutting edge, 1/4-inch shank, and 2-inch overall length support precise small-feature machining.
Two-flute upcut geometry promotes chip evacuation and stable material removal when the tool is correctly held and operated within suitable machining parameters for the selected material.
