Serrated Tooth Efficiency
The serrated cutting design is engineered to minimize the horsepower required during compatible door-mortising operations.


Ultimax-coated solid-carbide, right-hand upcut lock-mortise tool designed for CNC machining lock-set pockets in the sides of doors. Its 3/4-inch cutting diameter, 2-inch cutting edge, 3/4-inch shank, and 7-inch overall length support compatible deep-mortising operations.
Purpose-built for door lock-set mortising, this solid-carbide tool combines three upcut flutes, serrated tooth geometry, spinback relief, and Royce Ayr Ultimax coating for compatible deep-mortise CNC routing.
Designed for compatible CNC routers using precision 3/4-inch collets or approved toolholding systems with sufficient projection, clearance, and machine travel for door-side mortising.
The Royce Ayr 3-Flute Upcut Lock Mortise Tool R60-01758UM is designed for CNC routing of lock-set mortises in the sides of doors. Its dedicated geometry gives door and architectural-millwork producers a production tool for machining deep lock pockets where the verified 3/4-inch diameter, 2-inch cutting edge, and 7-inch overall length match the programmed operation.
Royce Ayr uses a serrated tooth design to reduce the horsepower required during cutting, while the spinback feature provides relief during deep-mortise machining. The three-flute upcut configuration supports chip evacuation from the cut and is intended for right-hand spindle rotation in compatible CNC router systems.
The tool has a 1-1/2-inch b1 dimension, 5-1/2-inch b2 dimension, 3/4-inch shank, solid-carbide/HW construction, and Ultimax coating. Correct collet condition, tool projection, runout, spindle speed, feed rate, plunge strategy, pass depth, workholding, and chip extraction are essential for safe, repeatable lock-mortise production.
Technical Specifications
The serrated cutting design is engineered to minimize the horsepower required during compatible door-mortising operations.
Spinback geometry provides relief while the tool machines deeper lock pockets, supporting controlled clearance in the cut.
Solid-carbide/HW construction and Royce Ayr Ultimax coating support production use where the tool geometry and cutting parameters are correctly matched.
Confirm that the CNC router spindle, collet, chuck, or toolholder accepts an exact 3/4-inch (19.05 mm) shank and safely supports the required tool projection. Verify right-hand rotation, collet condition, runout, spindle speed, feed rate, plunge strategy, pass depth, cutting depth, door material, fixturing, part hold-down, machine clearance, guarding, and dust extraction before machining. Confirm that the 7-inch overall length, 2-inch cutting edge, 1-1/2-inch b1 dimension, and 5-1/2-inch b2 dimension match the programmed lock-mortise operation.
The Royce Ayr 3-Flute Upcut Lock Mortise Tool R60-01758UM provides a purpose-built solid-carbide solution for CNC door and architectural-millwork production. Its 3/4-inch cutting diameter, 2-inch cutting edge, 3/4-inch shank, and 7-inch overall length are configured for compatible lock-set mortising applications.
Serrated teeth help reduce cutting-power demand, spinback geometry provides relief in deep mortises, and the Ultimax-coated right-hand configuration supports repeatable production when toolholding, programming, feeds, speeds, workholding, and chip evacuation are correctly established.
