Designed for rapid cutting and fast plug removal of holes in stucco and wood and composite materials. The new Blue Boar Tungsten Carbide Tipped TCT hole cutter quickly bore holes in stucco, plaster & lath, plywood sheathing, clay pipe, Hardie cement board, wood, non ferrous materials, aluminum siding, hard or composite plastic. Engineered with a unique tooth design and using premium grade tungsten carbide tips, the hole cutters are able to withstand the demands of cutting through stucco while maintaining a cutting edge that cuts effectively through hard and soft wood, plywood, OSB, and chipboard. The extra deep 2" cutting depth is great for thick multilayer surfaces such as stucco over OSB or thick plaster over wood. The thread mounting of the cutter head on the 4" shaft enables the tool to withstand hard use in the toughest materials for hole after hole. Use with any ½" corded or cordless drill (hammer drills OK if hammer action is turned off). Includes TCT hole cutter, 4" shaft, 8mm carbide tipped masonry bit, ejector spring, hex wrench, and sturdy plastic storage tube.
