Woodhaven spiral up-cut router bits are solid carbide for long life, clean cuts, and consistent performance in hardwoods, softwoods, plywood, and MDF. The up-cut spiral geometry pulls chips up and out of the cut, keeping the cutting edge clear and reducing heat buildup during deep passes. These are the bits specified for use with Woodhaven's SOSS hinge jigs, dado jigs, and other mortising applications.
Available in 3/8 inch and 1/2 inch diameters in standard and extended lengths to reach deep mortises and through-cuts that shorter bits cannot access. Each bit is ground to tight tolerances for runout-free performance and is compatible with any router that accepts the corresponding shank size. Made to Woodhaven's specifications with a satisfaction guarantee.
