EXPAND ROTARY HAMMER UTILITY FOR MULTI-MATERIAL APPLICATIONSThe Milwaukee 48-66-1370 SDS and Chuck Adapter Kit is a critical accessory for professionals who need to pivot quickly between heavy-duty masonry work and precision drilling in wood or metal. By bridging the gap between SDS-Plus drive systems and standard straight-shank twist bits, this kit eliminates the need to carry a secondary drill for lighter tasks. The industrial-grade, all-metal three-jaw chuck is engineered to maintain concentricity and grip strength under high-torque loads, ensuring that your rotary hammer—when switched to drill-only mode—performs with the accuracy of a dedicated drill/driver. This mechanical conversion maximizes your tool investment by providing the versatility required for diverse jobsite demands without sacrificing the rugged durability expected of Milwaukee components. / Industrial-grade all-metal chuck construction ensures long-term durability and resistance to jobsite debris and heavy daily use. / Seamlessly adapts SDS-Plus rotary hammers to accept 1/2 in. straight shank twist bits for maximum jobsite flexibility. / Precision-machined 1/2 in. - 20 thread adapter provides a secure, wobble-free connection to the rotary hammer spindle. / Keyed chuck design offers superior bit retention and torque transfer compared to standard keyless alternatives in high-demand drilling scenarios.
