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


Three-flute right-hand 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, 7/8-inch cutting edge, 0.215-inch upcut section, 3/8-inch shank, and 3-inch overall length combine opposing shear action with a compact production format for clean panel faces and chip-free dado routing.
Three-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 R60-12101 is a three-flute compression router bit for laminated or veneered wood and wood composites where top and bottom finish is critical. Royce Ayr's current series table lists a 0.3750-inch cutting diameter, 0.875-inch cutting edge, 0.215-inch upcut length, 0.375-inch shank, three 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 chip-free dado routing in compatible laminated and veneered panel applications.
The current live series lists coating type None for this exact base SKU and places the family within 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 short upcut section to support chip-free dado routing while preserving the verified 7/8-inch cutting edge configuration.
R60-12101 is the coating-None base configuration, distinct from the otherwise matching Ultimax-coated R60-12101UM 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 R60-12101 combines a 3/8-inch diameter, 7/8-inch cutting edge, 0.215-inch upcut section, 3/8-inch shank, three-flute right-hand compression geometry, coating None, and a 3-inch overall length.
Its opposing shear action is designed to protect top and bottom laminate faces while the short upcut supports chip-free dado work in laminated, veneered, and wood-composite CNC production.
