Featuring a specially designed ground tungsten carbide tip, this drill bit is built to last. Heat-treated for extended lifespan, it has a hexagon shank to prevent slippage in the drill chuck, enhancing speed and efficiency. The sandblast finish adds to its durability. For sizes 16mm diameter and larger, the shank is reduced to 12.7mm. Perfect for drilling into stone, brick, concrete, and most types of masonry. The drill bit is 150mm long. Available for delivery (charge applies at checkout) or collection from our yard.
