Serrated Roughing Geometry
Three serrated cutting flutes divide the cutting engagement to support productive stock removal with lower cutting demand than a comparable continuous finishing edge.


Solid-carbide, right-hand, three-flute upcut roughing router bit with a 20 mm cutting diameter, 102 mm cutting edge, and 20 mm shank. The serrated high-helix geometry is intended for efficient stock removal and upward chip evacuation in demanding CNC routing work.
A long-cut solid-carbide roughing tool combining three serrated cutting flutes with upcut chip flow for productive material removal in compatible CNC routing systems.
Designed for compatible CNC routers using an exact 20 mm precision collet or approved 20 mm toolholding system. Confirm projection, spindle limits, feed strategy, and workholding before use.
The Royce Ayr High-Helix Upcut Roughing Router Bit R60-01715 is identified in Titan’s catalogue as a 20 mm-diameter solid-carbide upcut rougher with a 102 mm cutting edge, 20 mm shank, and three-flute geometry. This long cutting envelope is intended for deep profiling and high-volume stock removal where adequate machine clearance and rigid workholding are available.
Its serrated high-helix cutting geometry breaks the cutting load into smaller engagements, reducing the horsepower demand compared with a continuous-edge finishing tool of similar size. The upcut helix directs chips toward the toolholder side of the cut to support evacuation from deep channels and profiles.
The current Royce Ayr online series does not publish this legacy/special metric SKU or an overall-length value. Selection must therefore be based on the verified 20 mm diameter, 102 mm cutting edge, 20 mm shank, Z3 roughing geometry, and right-hand rotation; overall length and safe clamping length must be confirmed from the physical tool or Royce Ayr before setup.
Technical Specifications
Three serrated cutting flutes divide the cutting engagement to support productive stock removal with lower cutting demand than a comparable continuous finishing edge.
The long published cutting edge supports deep routing work when the machine, toolholder, projection, workholding, and programmed passes are appropriate for the application.
The high-helix upcut design carries chips upward from deep profiles and channels, helping prevent recutting when extraction and machine conditions are properly managed.
Confirm SKU R60-01715, the exact 20 mm shank, actual overall length, safe clamping length, tool projection, right-hand spindle rotation, collet condition, and machine clearance before installation. Because no overall length is published in the available source records, measure the physical tool or obtain written Royce Ayr confirmation before programming depth or clearance. Establish spindle speed, feed rate, and pass depth for the machine, material, workholding, extraction, and roughing application.
The Royce Ayr High-Helix Upcut Roughing Router Bit R60-01715 combines a 20 mm solid-carbide body, 102 mm cutting edge, 20 mm shank, and three-flute serrated high-helix geometry for demanding CNC stock-removal work.
Upcut chip flow and interrupted roughing edges support efficient evacuation and reduced cutting demand, while final operating parameters and all clearance-critical dimensions must be verified for the specific machine and physical tool.
