System Fit

Designed for compatible CNC routers and industrial routing systems that accept a precision 3/8-inch shank and support the required left-hand spindle and programming setup.

Main Product Description

The Royce Ayr 2-Flute Left-Hand Downcut Spiral Router Bit R57-32226 is designed for clean, controlled routing in production woodworking and panel-processing environments. Its downcut geometry directs cutting pressure toward the workpiece, helping support the upper surface and reduce top-edge breakout during dados, grooves, pockets, profiles, and laminated-panel machining.

The 3/8-inch cutting diameter provides a practical balance of strength, cut width, and access for CNC routing work. Its 1-1/4-inch cutting edge, matching 3/8-inch shank, and 3-inch overall length support common dado, pocketing, groove, profile, and through-cut operations when the programmed depth, projection, and machine clearance match the verified geometry.

This solid-carbide tool uses two downcut spiral flutes and is specifically identified as a left-hand tool. The supplied source does not specify coating, so that detail should be confirmed before ordering if required. Correct spindle direction, toolpath orientation, collet condition, minimum practical projection, runout, RPM, feed rate, depth-per-pass, workholding, and chip or dust evacuation are essential for reliable performance.

Product Highlights

01

Verified Left-Hand Design

This SKU is specifically identified as a left-hand tool and must match the spindle direction, toolpath orientation, and toolholding setup.

02

Downcut Top-Edge Control

The downcut spiral directs cutting pressure toward the workpiece to help reduce upper-surface breakout in laminated and wood-based materials.

03

1-1/4-Inch Cutting Reach

The verified cutting-edge length supports controlled dados, grooves, pockets, profiles, panel details, and compatible through-cut operations.

Before Machining

Compatibility & Installation Notes

Confirm the spindle direction before ordering or installing this tool. SKU R57-32226 is identified as a left-hand tool and is not interchangeable with a standard right-hand tool in an incompatible setup. Verify that the collet or toolholder accepts an exact 3/8-inch (9.53 mm) shank and provides adequate clearance for the 3-inch overall length and required projection. Match RPM, feed rate, cutting depth, workholding, guarding, and chip or dust evacuation to the selected material.

Production Outcome

Control Left-Hand Downcut Routing

The Royce Ayr 2-Flute Left-Hand Downcut Spiral Router Bit R57-32226 provides a solid-carbide solution for clean top-edge routing in solid wood, wood composites, laminated materials, MDF, plywood, and selected plastics.

Its 3/8-inch cutting diameter, 1-1/4-inch cutting edge, matching shank, two-flute downcut geometry, left-hand designation, and 3-inch overall length support controlled production machining when correctly matched to the spindle, toolholder, and program.
