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


HW/carbide two-flute right-hand low-helix compression router bit for laminated or veneered plywood where both top and bottom finish are critical. Its 3/8-inch cutting diameter, 7/8-inch cutting edge, 0.200-inch upcut section, 3/8-inch shank, and 3-inch overall length combine upward and downward shearing action to help prevent laminate chipping while minimizing core furring or pullout.
Two-flute HW/carbide compression geometry with right-hand rotation. Upward and downward shearing action is designed to control chipping on both faces of laminated or veneered plywood while the low-helix geometry helps minimize core furring or pullout.
Designed for compatible CNC routers using precision 3/8-inch collets or approved 3/8-inch toolholding systems.
The Royce Ayr R60-15002 is a two-flute low-helix compression router bit for laminated or veneered plywood where top and bottom finish is critical. The current manufacturer specification is a 0.3750-inch cutting diameter, 0.875-inch cutting edge, 0.200-inch upcut length, 0.375-inch shank, two flutes, right-hand rotation, and a 3.000-inch overall length.
Royce Ayr specifies upward and downward shearing action to help prevent laminate chipping on both panel faces. The low-helix compression geometry is also designed to minimize core furring or pullout in plywood, supporting cleaner nested-routing results in laminated and veneered panel work.
The exact SKU is listed with material HW and coating None. Royce Ayr also notes that this geometry performs well in composite materials such as wood with CFRP laminates. Correct collet condition, runout, tool projection, spindle speed, feed rate, pass depth, workholding, and extraction remain essential for repeatable production.
Technical Specifications
Upward and downward shearing action supports both panel faces and helps prevent chipping where top and bottom finish are critical.
Royce Ayr specifies the low-helix geometry to minimize core furring or pullout in plywood and support cleaner laminated-panel routing.
The verified 3/8-inch diameter, 7/8-inch cutting edge, 0.200-inch upcut, 3/8-inch shank, and 3-inch overall length match R60-15002.
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, plywood, or wood/CFRP composite being machined.
Royce Ayr R60-15002 combines a 3/8-inch diameter, 7/8-inch cutting edge, 0.200-inch upcut section, 3/8-inch shank, two-flute low-helix compression geometry, right-hand rotation, and 3-inch overall length.
Its opposing shearing action is designed to protect both panel faces from chipping while the low-helix geometry helps minimize core furring or pullout in plywood and compatible wood/CFRP composite routing.
