The DeWalt SDS Plus Masonry Drill Drive Set is a comprehensive set designed for both trade professionals and DIY users. It features a toughcore, a tapered central core that increases stability and durability, reducing breakage and preventing bit fracturing when drilling deep holes with increased side loads. The set offers easy screwdriver bit removal and retention, with bits that lock into place to prevent them from falling out. The connectable case allows multiple sets to be stacked and locked together. Supplied as a 19-piece Masonry Drill Drive Set. Key features include wear marks to indicate correct hole diameter and bits that lock securely. The set is supplied in a Medium ToughCase+, which is part of a connectable case system that is TSTAK compatible, allowing individual cases to be clipped together for easy transportation. The ToughCase+ system provides organized storage solutions with premium features, including newly-designed bit storage with easy bit removal and clear lids for at-a-glance content visibility. The Small, Medium, and Large ToughCase+ Containers feature a proprietary latch system to connect to each other for optimized storage.
