Royce Ayr Low Helix Ripper Upcut 3 Flute Router Bit 3/4 in (19.05 mm)
3-Flute Low-Helix Ripper
Upcut Router Bit
Solid-carbide, right-hand, three-flute low-helix ripper upcut router bit designed to reduce tear-out in difficult wood grains while lowering cutting load and assisting chip evacuation. Its 3/4-inch cutting diameter, 2-1/8-inch cutting edge, 3/4-inch shank, and 5-inch overall length provide a heavy-duty format for compatible CNC routing applications.
Main Product Description
The Royce Ayr 3-Flute Low-Helix Ripper Upcut Router Bit R60-01607 is designed for CNC routing applications where tear-out control, reduced cutting load, and chip evacuation are important. Royce Ayr specifies a serrated tooth design intended to eliminate tear-out in difficult wood grains while reducing the horsepower required to cut.
The low-helix ripper geometry provides a controlled cutting action for roughing and heavy material removal, while the upcut configuration assists chip evacuation by drawing chips upward and away from the cutting zone. The three-flute format supports productive routing when matched to suitable spindle power, feed rate, and chip extraction.
The 0.7500-inch cutting diameter, 2.125-inch cutting edge, 0.750-inch shank, and 5.000-inch overall length require a compatible 3/4-inch collet or approved toolholder. Verify collet condition, runout, right-hand spindle rotation, tool projection, spindle speed, feed rate, depth per pass, workholding, material suitability, and dust or chip extraction before production.
Best Fit Applications
Product Highlights
Serrated Ripper Tooth Design
The serrated cutting form is intended to reduce tear-out in difficult wood grains and lower the horsepower required for material removal.
Upcut Chip Evacuation
The upcut configuration carries chips away from the cutting zone to support cleaner roughing and reduce chip recutting in compatible CNC operations.
Heavy-Duty 3/4-Inch Format
The 3/4-inch diameter and shank, 2-1/8-inch cutting edge, three-flute geometry, and 5-inch overall length suit larger production-routing setups.
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 5-inch (127 mm) overall length. Inspect the collet and nut, minimize unsupported tool projection, verify right-hand rotation and runout, and establish spindle speed, feed rate, depth per pass, workholding, machine horsepower, material suitability, and chip extraction according to the machine and approved shop procedures.
Improve Roughing and Chip Control
The Royce Ayr 3-Flute Low-Helix Ripper Upcut Router Bit R60-01607 provides a solid-carbide solution for demanding CNC routing in difficult wood grains. Its 3/4-inch diameter, 2-1/8-inch cutting edge, 3/4-inch shank, three-flute geometry, and 5-inch overall length support larger roughing, hogging, and production-routing applications.
Serrated ripper-style cutting geometry helps reduce tear-out and cutting load, while the upcut form assists chip evacuation when the tool is correctly held and operated within suitable machining parameters.
