Two Upcut Spiral Flutes
Z2 spiral cutting edges lift chips toward extraction for good chip evacuation in compatible routed materials.


Uncoated HW solid-carbide, right-hand upcut-spiral router bit for solid wood, wood composites and some plastics. Its 6 mm cutting diameter, 25 mm cutting edge, 6 mm shank and 66 mm overall length provide a compact Z2 configuration for compatible CNC routing applications.
A two-flute HW solid-carbide routing tool with upcut spiral geometry, right-hand rotation and compatibility across solid wood, wood composites and some plastics.
For compatible CNC routers using precision 6 mm collets or approved toolholding. Confirm work material, tool projection, workholding, extraction and cutting parameters before use.
The Royce Ayr General-Purpose Upcut-Spiral Router Bit R52-35412 is specified for routing solid wood, wood composites and some plastics. Its 6 mm cutting diameter, 25 mm cutting edge, 6 mm shank and 66 mm overall length form a compact configuration for compatible CNC-routed components.
Two upcut spiral flutes move chips toward extraction for good chip evacuation. The upward axial force requires secure workholding and correctly supported material throughout the cut.
The right-hand Z2 tool is manufactured from HW solid carbide and carries no coating. Correct 6 mm collet condition, minimum practical projection, runout control, feed rate, spindle speed, pass depth and chip evacuation remain essential for safe use and consistent finish quality.
Technical Specifications
Z2 spiral cutting edges lift chips toward extraction for good chip evacuation in compatible routed materials.
Royce Ayr lists this series for solid wood, wood composites and some plastics, allowing one geometry to serve several common routed materials.
The 6 mm cutting diameter and shank, 25 mm cutting edge and 66 mm overall length form the exact published metric configuration.
Confirm SKU R52-35412, the exact 6 mm shank, 66 mm overall length, safe clamping length, right-hand spindle rotation, collet condition, tool projection, machine clearance and workholding before installation. Match speed, feed, pass depth and extraction to the actual solid wood, wood composite or compatible plastic being routed.
The Royce Ayr General-Purpose Upcut-Spiral Router Bit R52-35412 provides an uncoated solid-carbide Z2 solution with a 6 mm diameter, 25 mm cutting edge, 6 mm shank and 66 mm overall length.
Its upcut spiral geometry provides good chip evacuation across the officially listed material range when toolholding, work support and cutting parameters are correctly controlled.
