Royce Ayr 3 Flute Downcut Low Helix Ripper 1/2 in (12.7 mm)
3-Flute Downcut Low Helix
Ripper Router Bit
Solid-carbide 3-flute downcut low helix ripper router bit designed for CNC routing and roughing where material hold-down, tear-out control, and efficient stock removal are priorities. Its 1/2-inch cutting diameter, 1-5/8-inch cutting edge, matching 1/2-inch shank, and 4-inch overall length support deeper profiles, pockets, hogging passes, solid wood machining, and wood-composite production work.
Main Product Description
The Royce Ayr 3-Flute Downcut Low Helix Ripper Router Bit R60-01404 is designed for CNC routing work where material hold-down and roughing performance matter. Its downcut geometry helps push the workpiece toward the spoilboard or fixture, while the serrated ripper-style tooth design is intended to reduce tear-out in difficult wood grains.
The 1/2-inch cutting diameter and 1-5/8-inch cutting edge support deeper profile routing, pocketing, hogging, and material-removal passes in solid wood and wood-composite applications. The matching 1/2-inch shank and 4-inch overall length require a correctly sized collet or toolholder, controlled projection, adequate machine clearance, and suitable workholding.
This solid-carbide tool uses three downcut low-helix flutes and is intended primarily for roughing and pre-finishing operations. Rotation, coating, RPM limit, and country of origin are not specified by the supplied source and should be confirmed before ordering or programming. Correct runout, chipload, pass depth, ramping strategy, spoilboard condition, dust extraction, and heat control remain essential.
Best Fit Applications
Product Highlights
Downcut Hold-Down Support
The downcut spiral directs cutting pressure toward the table or fixture to support workpiece control during compatible routing.
Serrated Ripper Tooth Geometry
The ripper-style serrated tooth design is intended to reduce tear-out in difficult wood grains while supporting efficient stock removal.
Longer Roughing Format
The 1-5/8-inch cutting edge and 4-inch overall length provide added reach for deeper profiles, pockets, and hogging passes.
Compatibility & Installation Notes
Confirm that the spindle, collet, and toolholder accept an exact 1/2-inch (12.7 mm) shank and provide adequate clearance for the 4-inch overall length and required projection. Rotation, coating, and RPM limits are not specified by the supplied source, so verify those details before ordering or programming. Match chipload, feed speed, pass depth, ramping method, spoilboard condition, workholding, guarding, dust extraction, and heat control to the selected material and toolpath.
Improve Longer-Reach Roughing
The Royce Ayr 3-Flute Downcut Low Helix Ripper Router Bit R60-01404 provides a solid-carbide solution for roughing difficult wood grains, solid wood, and wood composites where material hold-down and tear-out control matter.
Its 1/2-inch cutting diameter, 1-5/8-inch cutting edge, matching shank, three-flute low-helix downcut geometry, serrated tooth form, and 4-inch overall length support deeper production routing when correctly held and operated.
