Blazing fast speed in a compact, well-balanced package provides the ultimate in performance and durability. The DS245-AC is equipped with an adjustable 5000 rpm motor designed for high-volume applications such as drywall (into wood or light gauge steel studs), sheathing, cement board, and underlayment applications. SENCO’s patented corner-fit feed system allows for placement of screws into tight places otherwise unreachable by any other collated screwdriver on the market.
