The HEX-9 MultiConstruction drill bit offers stable drilling in all materials. Bosch's proprietary carbide blend and diamond-ground cutting edges make the drill bit wear-resistant, while the two-spiral U-shape ensures good chip transport and a long lifespan. Additionally, the carbide tip allows for easy starting and good guidance during drilling. The drill bit is suitable for practically all materials in interior construction, such as soft concrete, masonry, bricks, cement, lightweight building materials, multilayer materials, ceramics and tiles, wood, plastic, thin sheet metals, and aluminum. It features a 1/4" hex shank for use in cordless drills and impact drill chucks with a 1/4" tool holder.
