Royce Ayr 3-Flute High-Helix Downcut Ripper Bit 1/2 in (12.7 mm)
3-Flute Downcut High Helix
Ripper Router Bit
Uncoated HW solid-carbide right-hand 3-flute high-helix downcut ripper router bit designed for CNC routing where material hold-down, top-edge control, and reduced tear-out in difficult wood grains are important. Its 1/2-inch cutting diameter, 1-5/8-inch cutting edge, matching 1/2-inch shank, and 4-inch overall length support deeper routing, roughing, ripping, profiling, and material-removal operations.
Main Product Description
The Royce Ayr 3-Flute Downcut High Helix Ripper Router Bit R60-01504 is designed for CNC routing where the tool must control surface tear-out while helping keep the material pressed toward the table during cutting. It is part of the High-Helix Ripper Downcut series within Royce Ayr solid-carbide CNC tooling.
The serrated tooth geometry is intended to reduce tear-out in difficult wood grains while lowering the horsepower required to cut compared with a conventional smooth-edge tool. The downcut design directs cutting force toward the table, making this bit useful when top-edge quality and material hold-down are important considerations.
The 1/2-inch cutting diameter, 1-5/8-inch cutting edge, matching 1/2-inch shank, three-flute configuration, right-hand rotation, and 4-inch overall length provide added reach for compatible CNC routing setups. This uncoated HW solid-carbide tool must be matched to the machine spindle, collet, toolholder, programmed feed and speed, cutting depth, workholding, and actual material being machined.

Product Highlights
Serrated Downcut Geometry
The serrated tooth design is intended to reduce tear-out while lowering the horsepower required to cut.
Material Hold-Down Support
The downcut design directs cutting force toward the table when top-edge quality and workpiece control are priorities.
Longer 1-5/8-Inch Reach
The verified cutting edge and 4-inch overall length support deeper routing operations in properly matched CNC setups.
Compatibility & Installation Notes
Confirm that the machine spindle, toolholder, and collet accept an exact 1/2-inch (12.7 mm) shank and support right-hand rotation. Verify available clearance, tool projection, programmed cutting depth, and whether the 1-5/8-inch cutting edge is appropriate for the part thickness and cutting strategy. Match RPM, feed speed, chipload, hold-down method, guarding, dust or chip extraction, and material suitability to the actual operation.
Improve Longer-Reach Downcut Ripping
The Royce Ayr 3-Flute Downcut High Helix Ripper Router Bit R60-01504 provides an uncoated HW solid-carbide solution for CNC routing that requires material hold-down and improved control of tear-out in difficult wood grains.
Its 1/2-inch cutting diameter, 1-5/8-inch cutting edge, matching shank, three-flute high-helix downcut geometry, right-hand rotation, and 4-inch overall length support controlled production machining when correctly held and operated.
