Whiteside Spiral Upcut Double Flute Router Bits

Whiteside Spiral Upcut Double Flute Router Bits — Solid Carbide, USA Made

Holbren carries the full line of Whiteside solid carbide spiral upcut double flute router bits — a workhorse choice for woodworkers and CNC operators who need fast, clean material removal with excellent chip evacuation. The upcut spiral geometry pulls chips up and out of the cut, keeping the cutting zone clear, reducing heat buildup, and improving both bit life and surface quality. The double flute design delivers smooth, balanced cutting action across a wide range of materials.

These bits are ideal for grooving, slotting, mortising, profile cutting, and deep passes in hardwood, softwood, plywood, MDF, and composites. The entire collection is machined from solid carbide at Whiteside's plant in Claremont, North Carolina — delivering the rigidity, heat resistance, and precision that professionals rely on. With 27 sizes in stock, ranging from 1/8" to 3/4" cutting diameter and shank sizes from 1/4" to 3/4", you'll find the exact specification your project requires.
