For drilling through layered materials including brick, concrete, steel, and wood, this 5-pack carbide drill bit set provides up to 10x longer life in stacked materials. Each bit is built with a ¼" (6.4 mm) hex shank for compatibility with impact drivers and hammer drills, performing up to 85% faster in metal than standard masonry bits. The kit contains five 6" (15.2 cm) bits in 5/32" (4 mm), 3/16" (4.8 mm), ¼" (6.4 mm), 5/16" (7.9 mm), and 3/8" (9.5 mm) diameters, all offering a 4" (10.2 cm) useable cutting depth.
