Serious about woodworking? This Amana Tool spiral plunge bit is built for speed and a smooth finish in hardwoods. It’s an up-cut style, which means it pulls chips up and out of the cut, giving you cleaner grooves and less burning. The bit has a 3/8-inch diameter, a 1-1/4-inch cutting length, and a 3/8-inch shank (fits most routers). It’s made from solid carbide with two flutes and a sharp helix angle, allowing for fast feed rates, deep plunges, and mirror-like finishes in materials like oak, maple, or walnut. Recommended RPM is around 20,000–21,000 for optimal performance. Whether you’re doing mortising, deep grooves, or CNC work, this bit is a pro-grade tool that delivers precision and durability. Amana Tool is known for quality, and this bit is no exception.
