Serrated Ripper Tooth Design
The serrated tooth form is intended to help control tear-out in difficult wood grains while reducing cutting horsepower demand.


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 5/8-inch cutting diameter, 1-5/8-inch cutting edge, matching 5/8-inch shank, and 4-inch overall length support production routing in moulding, millwork, stair, railing, and construction-related wood-machining applications.
This production tool combines HW solid-carbide construction, three high-helix downcut flutes, right-hand rotation, and serrated ripper tooth geometry to help control tear-out while supporting material hold-down.
Designed for compatible CNC routers using a precision 5/8-inch collet or approved toolholding assembly with right-hand spindle rotation.
The Royce Ayr 3-Flute Downcut High Helix Ripper Router Bit R60-01505 is part of Royce Ayr's solid-carbide CNC tooling range. It is designed for wood-routing applications where reduced tear-out, top-surface control, and material hold-down are important.
The serrated tooth design is intended to help control tear-out in difficult wood grains while reducing cutting horsepower demand. The downcut geometry directs cutting pressure toward the table, supporting cleaner top-side cutting and improved part stability when the machine setup, workholding, and toolpath are properly matched.
This uncoated HW solid-carbide tool uses three high-helix downcut flutes and right-hand rotation. Its 5/8-inch cutting diameter, 1-5/8-inch cutting edge, matching 5/8-inch shank, and 4-inch overall length suit production CNC work in moulding, millwork, stairs, railings, and construction-related wood machining. RPM, feed data, and country of origin are not specified by the supplied source and should be confirmed when required.
Technical Specifications
The serrated tooth form is intended to help control tear-out in difficult wood grains while reducing cutting horsepower demand.
The downcut geometry directs cutting pressure toward the table to support cleaner top-side cutting and improved part stability.
The 5/8-inch cutting diameter and shank with a 1-5/8-inch cutting edge suit compatible production CNC router setups.
Confirm that the CNC router spindle, collet, and toolholder accept an exact 5/8-inch (15.88 mm) shank and support right-hand rotation. Verify collet condition, runout, tool projection, available clearance, programmed cutting depth, RPM, feed speed, chipload, material suitability, part hold-down, spoilboard condition, guarding, and dust extraction before production. Downcut geometry can improve top-edge control and stability, but chip evacuation and heat control must be matched to the material and toolpath.
The Royce Ayr 3-Flute Downcut High Helix Ripper Router Bit R60-01505 provides an uncoated HW solid-carbide solution for production CNC routing where reduced tear-out and material hold-down are important.
Its 5/8-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 wood machining when correctly held and operated.
