Enhance your toolkit with the Bosch DDMS20 20-Piece Impact Tough™ Drill and Drive Set, engineered specifically to withstand the high-torque demands of modern impact drivers. This comprehensive set features the innovative Xtended Torsion Zone technology, which effectively absorbs torque peaks to reduce stress at the tip, delivering 10X longer life compared to standard impact bits.

Designed for the professional who values workflow organization, the included Custom Case System revolutionizes accessory storage. The durable case features a unique tilt-in/tilt-out mechanism that allows for rapid access to your most-used bits, while the rugged rubber bumpers protect against the harsh realities of the jobsite. With clear visibility and a customizable layout, you can spend less time searching for the right size and more time working. The included Black Oxide drill bits are treated to resist heat buildup and friction, ensuring clean, fast cuts and extended longevity.
