Woodhaven 15406 3/8" Spiral Upcut Bit – Precision Solid Carbide Cutting

The Woodhaven 15410 3/8" Spiral Upcut Bit is a high-performance cutting tool built for clean, accurate results in demanding woodworking applications. Made from solid carbide and featuring two sharp spiral flutes, this bit excels at plunge cuts, mortising, and deep routing where clean chip evacuation and smooth sidewalls are critical.

Its upcut design helps lift chips out of the cut, improving visibility and reducing heat buildup—making it ideal for through-cuts and deeper passes. Whether you're cutting hardwood, softwood, or composite materials, this bit delivers precision and durability in every use.

For clean dadoes or jointing on the surface of material, a downcut bit may be preferred. Otherwise, this upcut spiral is the go-to choice for most routing applications.
