Royce Ayr 2-Flute Spiral Up Cut Solid Carbide Router Bit - 5/8" Dia x 2-1/8" Cut, Left Hand
2-Flute General-Purpose
Upcut Spiral Router Bit
A left-hand, two-flute solid-carbide upcut spiral router bit for general-purpose routing in solid wood, wood composites, and selected plastics. Its 5/8-inch cutting diameter, 2-1/8-inch cutting edge, 5/8-inch shank, and 4-inch overall length support efficient chip evacuation in compatible CNC routing systems.
Main Product Description
The Royce Ayr 2-Flute General-Purpose Upcut Spiral Router Bit R52-32837 is a solid-carbide general-purpose routing tool for solid wood, wood composites, and selected plastics. Its 0.6250-inch cutting diameter and 2.125-inch cutting edge provide the reach and cutting capacity required for profiling, grooving, channel routing, and other production CNC operations.
The two-flute upcut spiral geometry moves chips upward and away from the cutting zone, supporting cleaner chip evacuation and reducing chip recutting. The tool is manufactured in a left-hand configuration and must only be used with a spindle and toolholding setup designed for the specified rotation.
The 0.625-inch shank and 4.000-inch overall length require a compatible precision collet or approved toolholder. Collet condition, runout, tool projection, spindle direction, spindle speed, feed rate, depth per pass, workholding, and dust or chip extraction should be established for the material and machine.
Best Fit Applications
Product Highlights
Upcut Chip Evacuation
The spiral upcut flute form carries chips away from the cutting zone to support cleaner material removal and reduce chip recutting.
Left-Hand Configuration
The tool is manufactured for left-hand rotation and must be paired with a spindle, collet, and machining setup designed for that direction.
Production-Scale Geometry
The 5/8-inch diameter, 2-1/8-inch cutting edge, 5/8-inch shank, and 4-inch overall length support deeper general-purpose CNC routing operations.
Compatibility & Installation Notes
Confirm that the CNC spindle and toolholder are designed for left-hand rotation and accept an exact 5/8-inch (15.875 mm) shank. Verify clearance for the 4-inch (101.6 mm) overall length, inspect the collet and nut, minimize unsupported tool projection, and check runout before machining. Set spindle speed, feed rate, depth per pass, workholding, and chip extraction according to the material, machine, and approved shop procedures.
Improve General-Purpose Chip Evacuation
The Royce Ayr 2-Flute General-Purpose Upcut Spiral Router Bit R52-32837 provides a solid-carbide solution for general-purpose routing in solid wood, wood composites, and selected plastics. Its 5/8-inch diameter and 2-1/8-inch cutting edge support profiling, grooving, channel routing, and other production CNC operations.
Two-flute upcut geometry supports efficient chip removal, while the 5/8-inch shank and left-hand configuration provide a defined system fit for compatible CNC spindles and precision toolholding equipment.
