Royce Ayr Lock Mortise Tool Upcut 3/4 in (19.05 mm)
3-Flute Lock Mortise
Upcut Tool
Uncoated HW solid-carbide right-hand 3-flute lock-mortise upcut tool designed for CNC machining of deep lock-set mortises in the sides of doors. Its serrated tooth geometry helps reduce cutting horsepower demand, while the upcut action supports chip evacuation and the spinback relief provides clearance during extended-reach mortise cutting. The tool features a 3/4-inch cutting diameter, 2-inch cutting edge, matching 3/4-inch shank, and 7-inch overall length.
Main Product Description
The Royce Ayr 3-Flute Lock Mortise Upcut Tool R60-01758 is designed specifically for machining deep mortises in the sides of doors for lock-set installation. It is a production-focused CNC router tool for window-and-door, moulding, millwork, stair, and railing shops that require dedicated tooling for deep door-lock mortising.
The serrated tooth geometry is intended to reduce the horsepower required during cutting. Its upcut design supports chip evacuation, while the spinback relief provides additional clearance during deep mortise work. The 3/4-inch cutting diameter, 2-inch cutting edge, 1-1/2-inch b1 dimension, 5-1/2-inch b2 dimension, matching 3/4-inch shank, and 7-inch overall length provide a heavy extended-reach format where rigidity and controlled machining are critical.
This model is the uncoated HW solid-carbide right-hand configuration with three flutes. Proper performance depends on matching the tool to the CNC router, collet or toolholder, available spindle power, programmed mortise depth, RPM, feed speed, door material, fixture, workholding, guarding, and dust extraction. RPM/feed data and country of origin are not specified by the supplied source.

Product Highlights
Dedicated Door Mortise Geometry
Designed specifically for CNC machining deep lock-set mortises in the sides of doors rather than general-purpose routing.
Serrated Tooth & Spinback Relief
The serrated geometry helps reduce horsepower demand, while the spinback relief supports clearance during deep mortise cutting.
Extended 3/4-Inch Format
The 3/4-inch diameter and shank, 2-inch cutting edge, and 7-inch overall length suit compatible heavy deep-mortising setups.
Compatibility & Installation Notes
Confirm that the CNC router spindle, collet, and toolholder accept an exact 3/4-inch (19.05 mm) shank and support right-hand rotation. Verify collet condition, runout, safe toolholder engagement, tool projection, machine travel, clearance for the 7-inch overall length, programmed mortise depth, pass strategy, RPM, feed speed, door material, guarding, dust extraction, and fixture or hold-down method. Confirm that the 2-inch cutting edge, 1-1/2-inch b1 dimension, and 5-1/2-inch b2 dimension match the required lock-mortise operation.
Improve Heavy Door Mortising
The Royce Ayr 3-Flute Lock Mortise Upcut Tool R60-01758 provides an uncoated HW solid-carbide solution for accurate, repeatable CNC routing of deep lock-set pockets in the sides of doors.
Its 3/4-inch cutting diameter and shank, 2-inch cutting edge, serrated tooth design, spinback relief, right-hand upcut geometry, and 7-inch overall length support extended-reach mortising when correctly held and operated.
