Royce Ayr Solid Carbide Low Helix Down Cut Router Bit - 3/4" Dia x 3-1/8" Cut
3-Flute Downcut Chipbreaker
Finisher Router Bit
Extra-reach solid-carbide downcut chipbreaker finisher for general-purpose routing in solid wood and wood composites. Its 3/4-inch cutting diameter, 3-1/8-inch cutting edge, 3/4-inch shank, three-flute geometry, and 6-inch overall length support deep production routing while helping produce a clean laminated dado edge and control furring or tear-out.
Main Product Description
The Royce Ayr 3-Flute Downcut Chipbreaker Finisher Router Bit R60-32008 is a general-purpose production tool for routing solid wood and wood composites. Its downcut geometry directs cutting force toward the work surface, helping produce a clean edge when cutting dados in laminated material.
Integrated chipbreakers divide larger chips into smaller fragments and help control furring and tear-out in compatible materials. The three-flute finisher format supports productive CNC machining when spindle speed, feed rate, chip load, workholding, and extraction are correctly matched to the application.
The 0.7500-inch cutting diameter, 3.125-inch cutting edge, 0.750-inch shank, and 6.000-inch overall length require rigid, low-runout toolholding and adequate machine clearance. Before machining, verify collet condition, right-hand spindle rotation, unsupported projection, depth per pass, feed rate, spindle speed, and chip extraction.
Best Fit Applications
Product Highlights
Clean-Edge Downcut Action
Downcut geometry directs cutting force toward the work surface to support cleaner top edges when routing laminated material.
Chipbreaker Finisher Geometry
Integrated chipbreakers help control chip size, furring, and tear-out while the three-flute format supports finish quality.
Extra-Reach Production Format
The 3-1/8-inch cutting edge and 6-inch overall length provide extended reach for compatible deep-routing applications.
Compatibility & Installation Notes
Confirm that the CNC router spindle or toolholder accepts an exact 3/4-inch (19.05 mm) shank and provides sufficient clearance for the 6-inch (152.4 mm) overall length. Use rigid, low-runout toolholding, minimize unsupported projection where possible, verify right-hand rotation, and establish suitable spindle speed, feed rate, depth per pass, workholding, and chip extraction for the material and cutting depth.
Improve Clean-Edge Deep Routing
The Royce Ayr 3-Flute Downcut Chipbreaker Finisher Router Bit R60-32008 provides an extra-reach solid-carbide solution for routing solid wood and wood composites where clean laminated dado edges and controlled chip formation are important.
Its 3/4-inch diameter and shank, 3-1/8-inch cutting edge, three-flute chipbreaker-finisher geometry, and 6-inch overall length suit compatible CNC systems when the tool is correctly held and operated within appropriate machining parameters.
