Hougen Extended Reach Cutters are designed for applications where additional reach and a shallow depth of cut is required. They’re ideally suited for trailer hitch installations, or single pass through holes in square and rectangular pipe and tubing. The cutter and arbor are a single-piece construction and include a spring loaded pilot for “popping out” the slug at the end of the cut. For use in 3/8" or larger drill chucks. Made in USA.
