Down Cut Slow Spiral 3 Flute

Product Description

Whiteside’s state-of-the-art 3 flute slow spiral router bits are designed to provide a super smooth finish in solid surface, hard plastics and hardwoods. These bits excel when routing materials with brittle surfaces, minimizing uplift and chipping.
Spirals produce a razor sharp vertical shearing action in either up cut or down cut; unlike the standard straight cutting carbide tipped cutters (with brazed tips) which produce a lateral shearing action. When choosing spiral router bits always remember that up cut spirals direct shear towards the router and down cut spirals direct shear away from the router. Up cut therefore favours the face of the work piece facing away from the router and down cut favours the face of the work piece facing the router.
Up cut spirals direct chip clearance toward the router and are therefore useful for mortising and cutting dado's; conversely down cut spirals direct chip clearance away from the router.
Chip clearance is most proficient when extracted (by vacuum) in the same direction as shear.
Compatible with CNC, hand held and table mounted routers.
