Serrated Roughing Geometry
Three serrated cutting flutes divide the cutting engagement to support productive stock removal and reduce cutting demand in difficult wood grain.


Solid-carbide, right-hand, three-flute high-helix upcut roughing router bit with a 5/8-inch cutting diameter, 2-1/2-inch cutting edge, 5/8-inch shank, and 5-inch overall length. Serrated cutting edges support productive stock removal while the upcut helix assists chip evacuation.
A production-grade HW solid-carbide roughing tool combining three serrated cutting flutes, high-helix geometry, and right-hand upcut rotation for efficient stock removal in compatible CNC routers.
Designed for compatible CNC routers using precision 5/8-inch collets or approved toolholding systems. Confirm tool projection, spindle clearance, workholding, extraction, and programmed cutting parameters before use.
The Royce Ayr High-Helix Ripper Upcut Router Bit R60-01706 is engineered for production roughing in solid wood and compatible wood-based materials. Its 0.6250-inch cutting diameter, 2.500-inch cutting edge, and 0.625-inch shank provide a rigid long-cut configuration for deep profiling and high-volume material removal.
Royce Ayr specifies a serrated tooth design intended to reduce tear-out in difficult wood grain and lower the horsepower required to cut. The three-flute high-helix geometry divides the cutting engagement while the upcut action carries chips upward from deep profiles and channels.
The 5.000-inch overall length, HW solid-carbide construction, uncoated cutting edges, and right-hand rotation are suited to compatible CNC routers. Correct collet condition, clamping length, tool projection, runout, spindle speed, feed rate, depth per pass, extraction, and workholding remain essential for safe, repeatable production.
Technical Specifications
Three serrated cutting flutes divide the cutting engagement to support productive stock removal and reduce cutting demand in difficult wood grain.
The matching 5/8-inch cutting diameter and shank support rigidity across the published 2-1/2-inch cutting edge when projection and toolholding are correctly controlled.
The upcut helix carries chips upward from deep profiles and channels, helping reduce chip recutting when extraction and machine conditions are properly managed.
Confirm SKU R60-01706, the exact 5/8-inch shank, 5-inch overall length, safe clamping length, right-hand spindle rotation, collet condition, tool projection, machine clearance, and workholding before installation. The 2-1/2-inch cutting edge creates a long operating envelope; establish spindle speed, feed rate, and pass depth for the machine, material, extraction, and roughing application.
The Royce Ayr High-Helix Ripper Upcut Router Bit R60-01706 combines a rigid 5/8-inch solid-carbide body, 2-1/2-inch cutting edge, three serrated flutes, and a 5-inch overall length for demanding CNC stock-removal work.
High-helix upcut chip flow and interrupted roughing edges support efficient evacuation and reduced cutting demand when the tool is correctly held and operated within suitable machining parameters.
