Compression Shearing Action
Upward and downward shearing action supports both panel faces and helps prevent laminate chipping when top and bottom finish are critical.


HW/carbide two-flute right-hand mortise-compression router bit for CNC routing laminated or veneered wood and wood composites where both top and bottom finish are critical. Its 3/8-inch cutting diameter, 1-1/8-inch cutting edge, 0.188-inch upcut section, 3/8-inch shank, and 3-inch overall length combine compression shear with a short upcut for clean panel faces and chip-free dado routing.
Two-flute HW/carbide compression geometry with right-hand rotation. Upward and downward shearing action is designed to control laminate chipping on both faces, while the short upcut supports chip-free dado routing.
Designed for compatible CNC routers using precision 3/8-inch collets or approved 3/8-inch toolholding systems for nested routing, profiling, and compatible dado operations.
The Royce Ayr R60-12012 is a two-flute mortise-compression router bit for laminated or veneered wood and wood composites where top and bottom finish is critical. Royce Ayr's current exact product data lists a 0.3750-inch cutting diameter, 1.125-inch cutting edge, 0.188-inch upcut length, 0.375-inch shank, two flutes, right-hand rotation, and a 3.000-inch overall length.
Compression geometry combines upward and downward shearing action so both panel faces are supported during routing. Royce Ayr specifies this action to help prevent chipping of laminates, while the short upcut section allows a chip-free dado to be routed in compatible laminated and veneered panel applications.
The exact base SKU is listed with material HW and coating type None, and Royce Ayr categorizes the series under Solid Carbide Tooling. Correct collet condition, runout, tool projection, spindle speed, feed rate, pass depth, entry strategy, workholding, and extraction remain essential for repeatable CNC production.
Technical Specifications
Upward and downward shearing action supports both panel faces and helps prevent laminate chipping when top and bottom finish are critical.
Royce Ayr specifies the 0.188-inch upcut section to support chip-free dado routing while preserving the exact 1-1/8-inch cutting edge configuration.
R60-12012 is the coating-None HW/carbide base configuration, distinct from the otherwise dimensionally matching Ultimax-coated R60-12012UM variant.
Confirm that the CNC router toolholder accepts the exact 3/8-inch (9.525 mm) shank and provides suitable clearance for the 3-inch overall tool length. Verify right-hand spindle rotation, inspect the collet and nut, minimize unsupported projection, check runout, secure the workpiece, and establish spindle speed, feed rate, pass depth, entry strategy, and extraction for the actual laminated, veneered, or wood-composite panel.
Royce Ayr R60-12012 combines a 3/8-inch diameter, 1-1/8-inch cutting edge, 0.188-inch upcut section, 3/8-inch shank, two-flute right-hand mortise-compression geometry, coating None, and a 3-inch overall length.
Its opposing shear action protects top and bottom laminate faces while the short upcut supports chip-free dado work, giving this HW/carbide tool a focused role in laminated, veneered, and wood-composite CNC production.
