Royce Ayr 3 Flute Upcut Lock Mortise Tool 1/2 in (12.7 mm)
3-Flute Ultimax Lock Mortise
Upcut Tool
Ultimax-coated solid-carbide right-hand 3-flute lock-mortise upcut tool designed for CNC routing of deep mortises in the sides of doors for lock-set hardware. Its serrated tooth geometry helps reduce cutting horsepower demand, while the upcut action supports chip evacuation and the spinback relief provides clearance during deep mortise cutting. The tool features a 1/2-inch cutting diameter, 1-1/2-inch cutting edge, matching 1/2-inch shank, and 6-inch overall length.
Main Product Description
The Royce Ayr 3-Flute Ultimax Lock Mortise Upcut Tool R60-01742UM is built for door-production, millwork, and related CNC environments that need to machine deep side mortises for lock-set hardware. It is part of Royce Ayr's solid-carbide CNC router tooling range and uses serrated tooth geometry intended to reduce horsepower demand during cutting.
The upcut action supports chip evacuation, while the spinback feature provides relief through deep mortise cuts. Its 1/2-inch cutting diameter, 1-1/2-inch cutting edge, 1-1/2-inch b1 dimension, 4-1/2-inch b2 dimension, matching 1/2-inch shank, and 6-inch overall length suit production environments where door-hardware pockets must be routed accurately and repeatedly.
This version uses three flutes, right-hand rotation, and an Ultimax coating. Royce Ayr lists the cutting material as HC and categorizes the tool within its solid-carbide tooling range. It is suited to window-and-door manufacturing, moulding and millwork, stairs and railings, and related extended-reach lock-mortise work. RPM/feed data and country of origin are not specified by the supplied source.

Product Highlights
Dedicated Lock Mortise Geometry
Designed for CNC routing deep lock-set mortises in the sides of doors where accurate, repeatable pocket machining is required.
Spinback Relief
The spinback feature provides relief for deep mortise work and supports the clearance and reach requirements of production door-lock machining.
Ultimax-Coated 6-Inch Format
The Ultimax-coated tool combines a 1/2-inch diameter and shank, 1-1/2-inch cutting edge, and 6-inch overall length.
Compatibility & Installation Notes
Confirm that the CNC router spindle, collet, and toolholder accept an exact 1/2-inch (12.7 mm) shank and support right-hand rotation. Verify collet condition, runout, safe toolholder engagement, projection, clearance for the 6-inch overall length, programmed mortise depth, plunge and pass strategy, RPM, feed speed, door material, guarding, dust extraction, and fixture or hold-down method before machining.
Improve Coated Deep Door Mortising
The Royce Ayr 3-Flute Ultimax Lock Mortise Upcut Tool R60-01742UM provides a coated solid-carbide solution for accurate, repeatable CNC routing of deep lock-set pockets in the sides of doors.
Its 1/2-inch cutting diameter and shank, 1-1/2-inch cutting edge, Ultimax coating, serrated tooth design, spinback relief, right-hand upcut geometry, and 6-inch overall length support extended-reach mortising when correctly held and operated.
