Designed for compatible equipment using an exact 5/16-inch precision collet or approved toolholder. Small-diameter tooling requires minimal projection, low runout, conservative engagement, secure workholding, and verified cutting parameters.
Main Product Description
The Royce Ayr 2-Flute General-Purpose Downcut Spiral Router Bit R57-22217 is a small-diameter general-purpose solid-carbide tool for detailed routing in solid wood, wood composites, and compatible plastics. Its 0.28125-inch cutting diameter, 1.000-inch cutting edge, 0.3125-inch shank, and 2.500-inch overall length support fine slots, narrow details, and compact internal geometry.
The two-flute downcut spiral directs axial cutting force toward the work surface. Royce Ayr identifies this family for general-purpose routing and notes that the downcut design can provide a clean edge when cutting a dado in laminated material, provided the spoilboard, chip evacuation, and workholding strategy suit the application.
Because the 9/32-inch cutting diameter is delicate, tool runout, projection, chip load, pass depth, ramping strategy, acceleration, heat, and recutting must be controlled carefully. The tool must be held in a clean, accurate 5/16-inch collet and operated within parameters appropriate for the material and machine.

Product Highlights
Two-Flute Downcut Geometry
Two spiral cutting edges provide downcut action for controlled top-edge results in compatible wood, composite, plastic, and laminated-material applications.
Compact 1/8-Inch Shank Tool
The 5/16-inch shank and 2-1/2-inch overall length suit precision toolholding, while minimal runout and controlled engagement are critical for the delicate cutting diameter.
Compatibility & Installation Notes
Confirm SKU R57-22217, the exact 5/16-inch shank, 2-1/2-inch overall length, safe clamping length, right-hand spindle rotation, collet condition, tool projection, spoilboard clearance, and workholding before installation. The 9/32-inch cutting diameter is delicate: verify low runout and establish conservative spindle speed, feed rate, ramping, entry, pass depth, acceleration, and chip-evacuation settings for the exact material and machine.
Machine Fine Details with Controlled Downcut Action
The Royce Ayr 2-Flute General-Purpose Downcut Spiral Router Bit R57-22217 provides a compact solid-carbide solution for fine routing with a 9/32-inch cutting diameter, 1-inch cutting edge, 5/16-inch shank, and 2-1/2-inch overall length.
Its two-flute downcut spiral supports narrow details and controlled top-edge machining when the tool is held concentrically and operated with parameters appropriate for its small cutting diameter.
