Royce Ayr 2-Flute Straight Carbide Router Bit - 1/2" Diameter x 1" Cut
3-Flute Downcut Low Helix
Finisher Router Bit
Solid-carbide downcut low-helix finisher for routing plastics and composites and for finish passes in solid wood. Its 1/2-inch cutting diameter, 1-1/8-inch cutting edge, 1/2-inch shank, three-flute geometry, and 3-1/2-inch overall length provide controlled finishing performance in compatible CNC routing systems.
Main Product Description
The Royce Ayr 3-Flute Downcut Low Helix Finisher Router Bit R60-22311 belongs to Royce Ayr's 3-Flute Downcut Low Helix Finisher series. The manufacturer specifies this series for routing plastics and composites and for finish passes in solid wood.
Its downcut flute direction and low-helix geometry support controlled material engagement during finishing operations. The three-flute format is suited to compatible CNC routing when spindle speed, feed rate, and chip load are correctly matched.
The 0.5000-inch cutting diameter, 1.125-inch cutting edge, 0.500-inch shank, and 3.500-inch overall length require rigid, low-runout toolholding and adequate machine clearance. Before machining, verify collet condition, right-hand spindle rotation, tool projection, spindle speed, feed rate, depth per pass, workholding, and chip extraction.
Best Fit Applications
Product Highlights
Downcut Finishing Direction
Downcut flute direction supports controlled finishing engagement in compatible plastics, composites, and solid wood.
Low-Helix Geometry
Low-helix geometry is intended for finish-routing applications where controlled cutting action is required.
1-1/8-Inch Cutting Edge
The 1-1/8-inch cutting edge and 3-1/2-inch overall length provide a compact reach for compatible CNC finishing operations.
Compatibility & Installation Notes
Confirm that the CNC router spindle or toolholder accepts an exact 1/2-inch (12.7 mm) shank and provides sufficient clearance for the 3-1/2-inch (88.9 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 being machined.
Add Controlled Downcut Finishing Capability
The Royce Ayr 3-Flute Downcut Low Helix Finisher Router Bit R60-22311 provides a solid-carbide solution for routing plastics and composites and for finish passes in solid wood.
Its 1/2-inch diameter and shank, 1-1/8-inch cutting edge, three-flute downcut low-helix geometry, and 3-1/2-inch overall length suit compatible CNC systems when the tool is correctly held and operated within appropriate machining parameters.
