Milwaukee SDS/Chuck Adapter Kit

EXPAND ROTARY HAMMER UTILITY FOR MULTI-MATERIAL APPLICATIONS

The 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.
