Tool Type

2 Flute Downcut Spiral

Two-flute solid-carbide downcut spiral geometry with left-hand rotation. The downcut action directs cutting force toward the work surface and is specified by Royce Ayr for clean dado edges in laminated material.

System Fit

Designed for compatible CNC routers and routing systems using an exact 1/2-inch shank interface. Confirm the machine and toolholder are configured for left-hand rotation before production use.

Main Product Description

The Royce Ayr R57-32233 is a two-flute downcut spiral router bit from the company's Precision CNC Tooling range. Manufacturer catalogue data identifies this exact left-hand configuration with a 0.500-inch cutting diameter, 1.625-inch cutting edge, 0.500-inch shank, and 3.500-inch overall length.

Royce Ayr describes the 2-Flute Downcut Spiral family as a general-purpose router for solid wood, wood composites, and some plastics. Its downcut geometry is specifically intended to give a clean edge when cutting a dado in laminated material, making the family useful where the upper surface finish at the cut matters.

R57-32233 is the left-hand version of this geometry, so spindle rotation and machine setup must match the tool. Use a precision 1/2-inch collet or approved toolholder, minimize unnecessary projection, verify runout, and establish spindle speed, feed rate, pass depth, workholding, and extraction for the actual workpiece and cut strategy.

Product Highlights

01

Left-Hand Downcut Geometry

R57-32233 is the left-hand version of Royce Ayr's two-flute downcut spiral geometry and requires matching machine rotation.

02

Clean Laminated Dado Edge

Royce Ayr specifies the downcut design to provide a clean edge when cutting a dado in laminated material.

03

1-5/8-Inch Cutting Edge

The verified 1-5/8-inch cutting edge is paired with a 1/2-inch diameter, 1/2-inch shank, and 3-1/2-inch overall length.

Before Machining

Compatibility & Installation Notes

R57-32233 is a left-hand tool. Confirm that the CNC router and toolholder are configured for left-hand rotation before installation. The toolholder must accept the exact 1/2-inch (12.70 mm) shank and provide clearance for the 3-1/2-inch overall length. Inspect the collet and nut, minimize unsupported projection, verify runout, secure the workpiece, and establish spindle speed, feed rate, pass depth, and extraction for the actual material and operation.

Production Outcome

Left-Hand Downcut Routing with a Clean Top Edge

Royce Ayr R57-32233 combines a 1/2-inch cutting diameter, 1-5/8-inch cutting edge, 1/2-inch shank, 3-1/2-inch overall length, two-flute solid-carbide construction, and left-hand downcut geometry.

Its downcut action is specified for general-purpose routing in solid wood, wood composites, and some plastics, with particular value where a clean upper edge is required when cutting dados in laminated material.
