Three-Flute Finishing Geometry
Three continuous cutting edges distribute tool engagement for controlled finish routing when chip load, runout, and machine conditions are correctly managed.


Solid-carbide, right-hand, three-flute downcut finishing router bit with a 20 mm cutting diameter, 102 mm cutting edge, and 20 mm shank. Its downcut geometry is intended for controlled finish passes in solid wood, hard plastics, fibreboard, and compatible laminated materials.
A long-cut HW solid-carbide finishing tool combining three continuous cutting flutes with right-hand downcut geometry for controlled finish routing in compatible CNC systems.
Designed for compatible CNC routers using an exact 20 mm precision collet or approved 20 mm toolholding system. Confirm tool projection, spindle clearance, workholding, and cutting parameters before use.
The Royce Ayr Triple-Flute Downcut Finishing Router Bit R59-01015 is identified in Titan’s catalogue as a 20 mm-diameter solid-carbide downcut finisher with a 102 mm cutting edge, 20 mm shank, and three-flute geometry. The long cutting envelope supports deep finish-routing work where adequate clearance, rigid toolholding, and secure workholding are available.
Royce Ayr’s Triple-Flute Downcut family is intended for hard plastics and finish passes on solid wood. Downward axial cutting action can help control the top edge of the workpiece, while three cutting flutes distribute engagement for consistent finish machining when feed, speed, and chip evacuation are correctly managed.
The current Royce Ayr online series does not publish this legacy/special metric SKU or an overall-length value. Selection must therefore remain based on the verified 20 mm diameter, 102 mm cutting edge, 20 mm shank, Z3 downcut finishing geometry, HW solid-carbide construction, and right-hand rotation; overall length must be confirmed from the physical tool or Royce Ayr before setup.
Technical Specifications
Three continuous cutting edges distribute tool engagement for controlled finish routing when chip load, runout, and machine conditions are correctly managed.
The verified long cutting edge supports deep finishing work when projection, collet grip, machine clearance, and workholding are appropriate for the operation.
Downward axial cutting action can help control the top edge of compatible workpieces while directing chips downward through the cut.
Confirm SKU R59-01015, the exact 20 mm shank, actual overall length, safe clamping length, tool projection, right-hand spindle rotation, collet condition, machine clearance, spoilboard clearance, and workholding 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, extraction, and finishing application.
The Royce Ayr Triple-Flute Downcut Finishing Router Bit R59-01015 combines a 20 mm solid-carbide body, 102 mm cutting edge, 20 mm shank, and three-flute downcut geometry for demanding CNC finishing work.
Continuous finishing edges and downward axial cutting action support controlled surface results when the tool is correctly held and all clearance-critical dimensions are verified before machining.
