Royce Ayr 3 Flute Downcut Low Helix Ripper 5/8 in (15.88 mm)
3-Flute Downcut Low-Helix
Ripper Router Bit
Heavy-duty solid-carbide downcut low-helix ripper designed for industrial CNC routing in difficult wood grain. Its 5/8-inch cutting diameter, 2-1/8-inch cutting edge, 5/8-inch shank, serrated tooth form, and 5-inch overall length support demanding production cuts where material control and tear-out reduction are priorities.
Main Product Description
The Royce Ayr 3-Flute Downcut Low-Helix Ripper Router Bit R60-01406 is designed for CNC and industrial routing applications where difficult wood grain, material control, and tear-out reduction are important. Its downcut geometry directs cutting pressure toward the table or spoilboard, helping support the workpiece during machining.
The serrated tooth design is intended to reduce tear-out in challenging grain while lowering the horsepower required to cut. A 0.6250-inch cutting diameter, 2.125-inch cutting edge, and three-flute low-helix configuration provide a heavy production format for roughing, ripping, profiling, and deeper routing passes.
This uncoated HW solid-carbide tool uses right-hand rotation, a 0.625-inch shank, and a 5.000-inch overall length. Correct collet condition, minimum practical projection, verified runout, suitable spindle capacity, RPM, feed rate, depth-per-pass, workholding, clearance, and chip evacuation are essential for maintaining dimensional control and tool life.

Product Highlights
Downcut Material Control
The downcut geometry directs cutting pressure toward the table or spoilboard to help support the workpiece during routing.
Serrated Ripper Tooth Form
The serrated design is intended to reduce tear-out in difficult wood grain while lowering the horsepower required to cut.
Heavy 5/8-Inch Format
The 5/8-inch diameter, 2-1/8-inch cutting edge, matching shank, and 5-inch overall length support demanding production routing.
Compatibility & Installation Notes
Confirm that the spindle and toolholder accept an exact 5/8-inch (15.88 mm) shank and provide sufficient clearance for the 5-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 spindle capacity, RPM, feed rate, depth-per-pass, workholding, guarding, and chip evacuation to the selected wood material and machine conditions.
Control Heavy Downcut Routing
The Royce Ayr 3-Flute Downcut Low-Helix Ripper Router Bit R60-01406 provides a rigid HW solid-carbide solution for demanding CNC routing in difficult wood grain.
Its serrated tooth form, 5/8-inch diameter, 2-1/8-inch cutting edge, matching shank, three-flute geometry, and 5-inch overall length support controlled production cutting when correctly held and operated.
