Royce Ayr 2-Flute Downcut High Impact Router Bit 1/4 in (6.35 mm)

2-Flute Downcut High Impact
Router Bit
Solid-carbide downcut high impact router bit designed for general-purpose CNC routing, clean top-edge dado work, and small-diameter machining in solid wood, wood composites, laminated materials, and selected plastics. Its 1/4-inch cutting diameter, 7/8-inch cutting edge, matching 1/4-inch shank, and 2-1/2-inch overall length provide a compact production format with shallower flutes and a thicker core for improved resistance to breakage.
Main Product Description
The Royce Ayr 2-Flute Downcut High Impact Router Bit R57-92501 is designed for general-purpose routing in woodworking and panel-processing environments. Its downcut cutting action directs pressure toward the work surface, helping support a cleaner top edge during dado cutting, small profiles, grooves, pockets, fixture work, and laminated-material machining.
The 1/4-inch cutting diameter, 7/8-inch cutting edge, matching 1/4-inch shank, and 2-1/2-inch overall length provide a compact format for compatible CNC router and routing-machine setups. The high impact design uses shallower flutes and a thicker core to improve resistance to breakage compared with more aggressive flute designs.
This solid-carbide tool uses two downcut flutes and is suited to solid wood, wood composites, laminated materials, and selected plastics. Rotation, coating, RPM limit, and country of origin are not specified by the supplied source and should be confirmed before ordering or programming when those details are required. Correct collet condition, minimum practical projection, verified runout, suitable feeds and speeds, depth-per-pass, workholding, and dust or chip evacuation remain essential.
Best Fit Applications
Product Highlights
High Impact Core Design
Shallower flutes and a thicker core improve resistance to breakage compared with more aggressive flute designs.
Clean Top-Edge Downcut
The downcut action directs pressure toward the workpiece to help support the top edge during compatible routing operations.
Compact 1/4-Inch Format
The matching cutting diameter and shank suit smaller CNC routing tasks where tool strength and cut control both matter.
Compatibility & Installation Notes
Confirm that the spindle, collet, and toolholder accept an exact 1/4-inch (6.35 mm) shank and provide adequate clearance for the 2-1/2-inch overall length and required projection. Rotation, coating, and RPM limits are not specified by the supplied source, so verify those details before ordering, programming, or installation. Check that the 7/8-inch cutting edge matches the programmed depth, and confirm feeds, speeds, pass depth, workholding, guarding, and dust or chip evacuation for the selected material.
Improve Small-Diameter Tool Strength
The Royce Ayr 2-Flute Downcut High Impact Router Bit R57-92501 provides a solid-carbide solution for clean top-edge routing in solid wood, wood composites, laminated materials, and selected plastics.
Its 1/4-inch cutting diameter, 7/8-inch cutting edge, matching shank, two-flute downcut geometry, thicker core, and 2-1/2-inch overall length support controlled production machining when correctly held and operated.
