Royce Ayr 3 Flute Upcut Low Helix Ripper 3/8 in (9.53 mm)
3-Flute Upcut Low Helix
Ripper Router Bit
Uncoated HW solid-carbide right-hand 3-flute upcut low-helix ripper router bit designed for CNC applications where chip evacuation, controlled roughing, and reduced tear-out in difficult wood grains are important. Its 3/8-inch cutting diameter, 1-1/8-inch cutting edge, matching 3/8-inch shank, and 3-1/2-inch overall length support nested routing, pocketing, dado-style work, millwork production, stair and railing components, and construction-related CNC machining.
Main Product Description
The Royce Ayr 3-Flute Upcut Low Helix Ripper Router Bit R60-01601 is part of the Precision CNC Tooling and Solid Carbide Tooling lineup. It is intended for CNC router work where the shop needs upcut cutting action, chip evacuation, and serrated tooth geometry for difficult wood-grain conditions.
The upcut geometry helps pull chips out of the cut, supporting nested routing, pocketing, dado-style work, and general CNC operations where packed chips can affect finish, heat, and tool performance. The low-helix ripper design uses a serrated tooth form intended to reduce tear-out in difficult wood grains while reducing horsepower required to cut.
This uncoated HW solid-carbide tool uses three low-helix upcut flutes and right-hand rotation. Its 3/8-inch cutting diameter, 1-1/8-inch cutting edge, matching 3/8-inch shank, and 3-1/2-inch overall length provide a compact roughing and ripping format. Series material codes include hardwood, softwood, and selected plastics. RPM, feed data, and country of origin are not specified by the supplied source.

Product Highlights
Upcut Chip Evacuation
The upcut geometry helps pull chips out of the cut during nested routing, pocketing, dado-style work, and general CNC operations.
Serrated Low-Helix Ripper
The serrated low-helix ripper tooth form is intended to reduce tear-out in difficult wood grains while lowering horsepower demand.
Compact 3/8-Inch Format
The 3/8-inch diameter and shank with a 1-1/8-inch cutting edge suit smaller-diameter roughing and ripping operations.
Compatibility & Installation Notes
Confirm that the CNC router spindle, collet, and toolholder accept an exact 3/8-inch (9.53 mm) shank and support right-hand rotation. Verify collet condition, runout, projection, programmed cutting depth, RPM, feed speed, chipload, material suitability, hold-down method, guarding, and dust or chip extraction. Because this is an upcut tool, confirm that upward cutting action is suitable for the required top-edge finish and part-hold-down strategy.
Improve Compact Upcut Ripping
The Royce Ayr 3-Flute Upcut Low Helix Ripper Router Bit R60-01601 provides an uncoated HW solid-carbide solution for CNC routing where chip evacuation and controlled cutting in difficult wood grain matter.
Its 3/8-inch cutting diameter, 1-1/8-inch cutting edge, matching shank, three-flute low-helix upcut geometry, right-hand rotation, and 3-1/2-inch overall length support compact production machining when correctly held and operated.
