Buying Guide

Choose the right spiral direction

Upcut spiral bits pull chips out of the cut and are preferable for deeper engraving and cleaner chip evacuation in most woodworking applications

Match shank diameter to your router

Select 1/4-inch or 1/2-inch shanks to match your collet size or use adapters; larger shanks improve rigidity for finer engraving control

Consider cutting diameter and length

Cutting diameter determines detail level while cutting length (CL) and overall length (OVL) affect reach—longer cutters are useful for deep relief but can flex more

Prefer solid-carbide for longevity

Solid-carbide spiral bits retain edge sharpness longer than tipped bits, which is important for consistent engraving quality

Balance set size vs. specific bits

Multi-piece sets offer variety for different engraving widths, while single extra-long or large-diameter bits are better when a specific size is regularly required
