Royce Ayr 3 Flute Upcut Lock Mortise Tool 3/4 in (19.05 mm)
3-Flute Upcut
Lock Mortise Tool
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.
Main Product Description
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.
Best Fit Applications
Product Highlights
Serrated Tooth Efficiency
The serrated cutting design is engineered to minimize the horsepower required during compatible door-mortising operations.
Spinback Deep-Mortise Relief
Spinback geometry provides relief while the tool machines deeper lock pockets, supporting controlled clearance in the cut.
Ultimax-Coated Solid Carbide
Solid-carbide/HW construction and Royce Ayr Ultimax coating support production use where the tool geometry and cutting parameters are correctly matched.
Compatibility & Installation Notes
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.
Machine Deep Lock Mortises with Dedicated Geometry
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.
