Spiral Bits (Solid Carbide)The solid carbide spiral bits in this group are designed for numerous applications. Excellent for plunge and other cuts, spiral bits leave behind high-quality surfaces. Up Cut or Down Cut versions are available for all spiral bits, except the Up/Down Combination Cut (Compression). The Up/Down Cut (Compression) bits are ideal for double-sided veneer plywood, melamine, and laminates. Flush trim spiral bits offer State-of-the-Art results in Flush trimming. The 1/4" diameter tools are great for small inside corners, while the 1/8" diameter bits are used for extremely sharp corners. Other spiral bits are available include Left Hand, Roughing (Hoggers), Three Flute, Slow, and O-Flute (used primarily for routing plastics).
