Main Product Description

The Royce Ayr Double-Flute Downcut Router Bit R57-02405 is part of the R57-024 / R57-124 hard-plastic and aluminum downcut series. It is designed for precision CNC routing where controlled top-side cutting action and a clean pocket-bottom finish are important.

Its 0.2500-inch cutting diameter and 0.750-inch cutting edge support compact profiling, trimming, slotting, and pocketing operations. The downcut geometry directs cutting pressure toward the workpiece, while the two-flute configuration supports controlled chip formation in suitable plastic and non-ferrous applications.

Royce Ayr identifies this family as providing an end-mill-style finish for improved pocket bottoms. The 0.250-inch shank, right-hand rotation, solid-carbide construction, and 2.500-inch overall length require precise collet condition, verified runout, suitable RPM, feed rate, plunge rate, depth-per-pass, workholding, and chip evacuation.

Performance Details

Product Highlights

01

Controlled Downcut Geometry

The downcut flute direction helps maintain top-side control during profiling, trimming, slotting, and pocketing passes.

02

Improved Pocket-Bottom Finish

The tool family is designed to produce an end-mill-style floor finish in compatible pocketing applications.

03

Compact 1/4-Inch Geometry

The 1/4-inch cutting diameter and shank support detailed CNC work where compact feature sizes and controlled cutting are required.

Before Machining

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 another shop-approved thermal-control method is required.

Production Outcome

Improve Compact Routing and Pocket Finish

The Royce Ayr Double-Flute Downcut Router Bit R57-02405 provides a compact solid-carbide solution for precision CNC routing in hard plastics and aluminum.

Its 1/4-inch diameter, 3/4-inch cutting edge, 1/4-inch shank, two right-hand flutes, and 2-1/2-inch overall length support controlled profiling, trimming, slotting, and pocketing when correctly applied.
