Two Straight Flutes
Z2 straight cutting edges provide neutral axial action for compatible routing operations in the officially listed material range.


Uncoated HW solid-carbide, right-hand straight-flute router bit for solid wood, MDF and compatible plastics. Its 1/4-inch cutting diameter, 3/8-inch cutting edge, 1/4-inch shank and 2-1/2-inch overall length provide a compact Z2 configuration for compatible CNC routing applications.
A two-flute HW solid-carbide routing tool with straight cutting geometry, right-hand rotation and broad compatibility across solid wood, MDF and selected plastics.
For compatible CNC routers using precision 1/4-inch collets or approved toolholding. Confirm work material, tool projection, workholding, extraction and cutting parameters before use.
The Royce Ayr General-Purpose Straight-Flute Router Bit R56-01806 is specified for routing solid wood, MDF and some plastics. Its 0.2500-inch cutting diameter, 0.375-inch cutting edge, 0.250-inch shank and 2.500-inch overall length form a compact configuration for compatible CNC-routed components.
Two straight flutes provide neutral axial cutting action without the upward or downward thrust associated with spiral geometry. This makes the tool a versatile general-purpose option when material support, workholding and chip extraction are correctly matched to the operation.
The right-hand tool is manufactured from HW solid carbide and carries no coating. Correct 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 straight cutting edges provide neutral axial action for compatible routing operations in the officially listed material range.
Royce Ayr lists this series for solid wood, MDF and some plastics, allowing one geometry to serve several common routed materials.
The 1/4-inch cutting diameter and shank, 3/8-inch cutting edge and 2-1/2-inch overall length support compact precision-routing work.
Confirm SKU R56-01806, the exact 1/4-inch shank, 2-1/2-inch 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, MDF or plastic being routed.
The Royce Ayr General-Purpose Straight-Flute Router Bit R56-01806 provides an uncoated solid-carbide Z2 solution with a 1/4-inch diameter, 3/8-inch cutting edge, 1/4-inch shank and 2-1/2-inch overall length.
Its straight cutting geometry and official compatibility with solid wood, MDF and some plastics make it a practical option when toolholding and cutting parameters are correctly controlled.
