Brener Tools, the makers of the SMAKT Tool, is inspired by 25 years of plumbing experience. SMAKT helps you core concrete in half the time, half the cost, half the price, and less than half the weight! After 25 years of core drilling, Brener Tools decided to solve an old industry frustration. So, we drew up plans for SMAKT, a new, faster, lighter, and cleaner method of core drilling. Because SMAKT uses 2 core bits simultaneously, you get consistent depth measurement each time; so, no taking apart the drill to change bits. A conventional 4 inch core, which took 60 minutes in non-composite concrete, switching to a 10-inch-bit, could now be finished in 20 minutes with SMAKT.
