Royce Ayr Straight Flute Wood & Plastic CNC Router Bit 1/4 in (6.35 mm)

2-Flute Straight-Flute
Router Bit
HW solid-carbide straight-flute router bit designed for general-purpose CNC routing in solid wood and hard plastic. Its 1/4-inch cutting diameter, 1-1/8-inch cutting edge, 1/4-inch shank, and 3-inch overall length support controlled slotting, pocketing, trimming, and profile work where neutral axial cutting action is preferred.
Main Product Description
The Royce Ayr 2-Flute Straight-Flute General Wood and Plastic Router Bit R56-21108 is designed for general-purpose routing in solid wood and hard plastic. Its straight-flute geometry provides neutral axial cutting action compared with upcut, downcut, or compression spiral tools, making it suitable where controlled sidewall cutting is preferred.
The 0.2500-inch cutting diameter and 1.125-inch cutting edge support through-routing, slotting, pocketing, trimming, and profile work. The 0.250-inch shank and 3.000-inch overall length provide a compact, familiar format for compatible CNC router collets and toolholding systems.
This uncoated HW solid-carbide tool uses two flutes and right-hand rotation. Correct collet condition, minimum practical projection, verified runout, suitable RPM, feed rate, depth-per-pass, workholding, and chip evacuation are essential for maintaining finish quality, dimensional control, and reliable tool life.
Best Fit Applications
Product Highlights
Neutral Straight-Flute Action
The straight geometry provides controlled sidewall cutting without the axial chip direction of upcut or downcut spirals.
Versatile 1/4-Inch Format
The 1/4-inch cutting diameter and matching shank suit common compatible CNC router collets and detail-routing setups.
Wood & Hard-Plastic Use
The official Royce Ayr series is specified for general-purpose routing in solid wood and hard plastic.
Compatibility & Installation Notes
Confirm that the spindle and toolholder accept an exact 1/4-inch (6.35 mm) shank and provide adequate clearance for the 3-inch overall length and required projection. Inspect and clean the collet, collet nut, and tool shank, minimize unsupported projection, verify runout, and confirm right-hand rotation before machining. Match RPM, feed rate, depth-per-pass, workholding, and chip evacuation to the selected wood or hard-plastic material.
Control Straight-Flute CNC Routing
The Royce Ayr 2-Flute Straight-Flute General Wood and Plastic Router Bit R56-21108 provides an uncoated HW solid-carbide solution for controlled routing in solid wood and hard plastic.
Its 1/4-inch diameter, 1-1/8-inch cutting edge, matching shank, two-flute geometry, right-hand rotation, and 3-inch overall length support repeatable production machining when correctly held and operated.
