Royce Ayr 2-Flute Straight Router Bit 3/8 in (9.53 mm)

3-Flute Low-Helix Downcut
Router Bit
Solid-carbide low-helix downcut router bit engineered for top-surface control in phenolic, dense plastics, composite materials, delicate veneers, and high-density panels. Its 1/2-inch cutting diameter, 1-1/4-inch cutting length, three-flute geometry, and 3-1/2-inch overall length support controlled CNC routing where clean upper edges and downward workpiece pressure are priorities.
Main Product Description
The Royce Ayr 3-Flute Low-Helix Downcut Router Bit R72-20007 is engineered for CNC routing applications where top-surface quality and workpiece stability are important. Its downcut action directs cutting pressure toward the table or spoilboard, helping support delicate upper surfaces during machining.
The 1/2-inch cutting diameter and 1-1/4-inch cutting length provide a practical format for routing phenolic, dense plastics, composite materials, delicate veneers, and high-density panels. The three-flute low-helix geometry supports controlled cutting action and a refined upper-edge finish in compatible applications.
This solid-carbide tool has a 3-1/2-inch overall length. The supplied source does not specify shank diameter, rotation, or coating, so those details must be confirmed before ordering or programming. Correct toolholding, minimum practical projection, verified runout, suitable RPM, feed rate, depth-per-pass, workholding, and chip evacuation are essential for reliable performance.
Best Fit Applications
Product Highlights
Top-Surface Control
The downcut action applies pressure toward the spoilboard to help stabilize the workpiece and protect the upper surface during routing.
Three-Flute Low-Helix Geometry
The three-flute configuration and low helix support controlled cutting in compatible phenolic, plastic, composite, and panel materials.
Solid-Carbide Construction
The solid-carbide body supports rigidity, cutting-edge retention, and repeatable dimensions in suitable CNC production applications.
Compatibility & Installation Notes
The supplied source does not state the shank diameter, rotation, or coating. Confirm those specifications with the product record or manufacturer before ordering, programming, or installation. Verify collet and toolholder compatibility, available clearance for the 3-1/2-inch overall length, minimum practical projection, runout, spindle direction, RPM, feed rate, depth-per-pass, workholding, and chip evacuation for the selected phenolic, plastic, composite, veneer, or panel material.
Improve Top-Surface Routing Control
The Royce Ayr 3-Flute Low-Helix Downcut Router Bit R72-20007 provides a solid-carbide solution for controlled CNC routing in phenolic, dense plastics, composite materials, delicate veneers, and high-density panels.
Its 1/2-inch cutting diameter, 1-1/4-inch cutting length, three-flute low-helix geometry, and 3-1/2-inch overall length support clean upper-edge machining when correctly matched to the spindle, toolholder, material, and cutting parameters.
