Abstract of the Disclosure A downhole cutting tool, specifically adapted to func- tion as an enhanced diameter clean-out tool, includes longi- tudinal bores which are opened to fluid flow when cutting members are moved to their extended positions. Upper and lower subassemblies are connected through an adapter which establishes an angular offset between an upper pair of extendible members and a lower pair of extendible members, which upper pair functions as a stabilizing structure to stabilize rotation of the tool and which lower pair func- tions as an enhanced diameter cutter.
