Bosch 1/2 in. SDS-Plus Chuck Adapter with 3/4 in. SDS-Max Shank transforms a powerful SDS-Max hammer into a versatile drilling tool, enabling you to run standard SDS-Plus bits without swapping machines. This adapter is purpose-built for masonry work where you need quick bit changes and reliable performance, especially when drilling smaller-diameter holes or working with concrete, brick, or stone.
Key to its versatility is the combination of a 1/2 in. keyless SDS-Plus chuck on a 3/4 in. SDS-Max shank. The keyless chuck lets you clamp and release bits with a simple twist, eliminating the need for a chuck key and speeding up transitions between holes. The 3/4 in. SDS-Max shank fits securely into your SDS-Max hammer, delivering solid power transfer and improved durability during tough masonry jobs.
