Main Product Description
The Royce Ayr Double-Flute Downcut Router Bit R57-02401 is designed for CNC routing in hard plastics and aluminum where top-side control and a clean pocket-bottom finish are required. Its 0.1250-inch cutting diameter and 0.500-inch cutting edge support detailed trimming, profiling, slotting, and pocketing operations.
The downcut geometry directs cutting pressure toward the workpiece and helps control the upper surface during machining. Royce Ayr identifies this family as providing an end-mill-style finish for improved pocket bottoms, making it well suited to detail work where clean floor finish and controlled edge quality are priorities.
The 0.250-inch shank, two cutting flutes, right-hand rotation, and 2.000-inch overall length are intended for precision CNC routing systems. Correct collet condition, verified runout, suitable spindle speed, feed rate, plunge rate, depth-per-pass, chip evacuation, and workholding are essential for controlling heat and maintaining dimensional accuracy.

Product Highlights
Improved Pocket-Bottom Finish
The tool family is designed to produce an end-mill-style floor finish in compatible pocketing applications.
Compact Precision Geometry
The 1/8-inch cutting diameter supports detailed CNC work where smaller profiles and controlled feature sizes are required.
Compatibility & Installation Notes
Confirm that the spindle and toolholder accept an exact 1/4-inch (6.35 mm) shank and that right-hand rotation matches the programmed cutting direction. Inspect and clean the collet, collet nut, and tool shank, verify runout, and establish suitable RPM, feed speed, plunge rate, and depth-per-pass. For aluminum and hard plastics, maintain effective chip evacuation and confirm whether air blast, coolant, or other shop-approved thermal-control methods are required.
