Royce Ayr 3-Flute Downcut Low Helix Ripper 3/4 in (19.05 mm)
3-Flute Downcut Low Helix
Ripper Router Bit
Heavy-format solid-carbide 3-flute downcut low-helix ripper router bit designed for CNC routing where material control, tear-out reduction, and efficient roughing performance matter. Its 3/4-inch cutting diameter, 2-1/8-inch cutting edge, matching 3/4-inch shank, and 5-inch overall length support larger parts, thicker stock, demanding wood grains, plywood, fiberboard, laminated board, and heavier production-routing passes.
Main Product Description
The Royce Ayr 3-Flute Downcut Low Helix Ripper Router Bit R60-01408 is designed for production CNC routing where material control, tear-out reduction, and efficient roughing performance are priorities. Its downcut geometry directs cutting pressure toward the workpiece and spoilboard, helping support material hold-down on nested panels, solid wood parts, and laminated board applications.
The serrated ripper-style tooth design is intended to reduce tear-out in difficult wood grains while lowering cutting horsepower requirements. The 3/4-inch cutting diameter, 2-1/8-inch cutting edge, matching 3/4-inch shank, and 5-inch overall length provide a heavy production format for larger parts, thicker stock, deep profiles, roughing, pocketing, and material-removal operations.
This solid-carbide tool uses three downcut low-helix flutes. Coating, kerf, rotation, RPM, and country of origin are not specified by the supplied source and should be confirmed before ordering or programming. Correct spindle power, collet condition, toolholder balance, projection, runout, chipload, pass depth, vacuum hold-down, dust extraction, and heat control remain essential.
Best Fit Applications
Product Highlights
Heavy 3/4-Inch Format
The 3/4-inch cutting diameter and shank support heavier routing passes when the spindle and toolholder are properly rated.
Downcut Material Control
The downcut geometry directs cutting pressure toward the table to support part stability during compatible CNC routing.
Serrated Ripper Tooth Design
The serrated tooth form is intended to reduce tear-out in difficult wood grains while supporting efficient stock removal.
Compatibility & Installation Notes
Confirm that the spindle, collet, and toolholder accept an exact 3/4-inch (19.05 mm) shank and provide adequate clearance for the 5-inch overall length and required projection. Coating, rotation, and RPM are not specified by the supplied source, so verify those details before ordering or programming. Because this is a large downcut tool, confirm spindle power, holder balance, chipload, feed speed, pass depth, vacuum hold-down, spoilboard condition, chip evacuation, guarding, and heat control before production use.
Improve Heavy Downcut Roughing
The Royce Ayr 3-Flute Downcut Low Helix Ripper Router Bit R60-01408 provides a solid-carbide solution for heavier routing in hardwood, softwood, plywood, fiberboard, laminated board, and difficult wood grains.
Its 3/4-inch cutting diameter, 2-1/8-inch cutting edge, matching shank, three-flute low-helix downcut geometry, serrated tooth form, and 5-inch overall length support demanding production machining when correctly held and operated.
