Main Product Description

This Royce Ayr solid carbide downcut spiral router bit is designed to route grooves, profiles and pockets. It is suitable for solid wood, wood composites, selected plastics and laminated materials.

The cutting section follows the programmed path or guide to form the required shape. Choose the entry method and depth of cut to suit the tool’s end geometry. The downcut geometry shears toward the workpiece, helping support the top edge during the pass. The solid-carbide cutting section provides rigidity and wear resistance at the working edge.

The 5/16 in cutting diameter and 1-1/8 in cutting length define the working section of this version. Its 1/2 in shank fits a holder or collet matched to that diameter.

Before Machining

Compatibility & Installation Notes

Confirm toolholding for the shank size 0.500" and right-hand spindle operation. Plastic suitability is conditional; confirm the exact grade and cutting conditions. The stated laminate edge benefit is for dados; it is not a guarantee for every laminate operation.
