Bosch Adapter, SDS-plus to 1/2″ External Square, 2608598037

Bosch 2608598037 Adapter, SDS-plus to 1/2" External Square

Bosch 2608598037 is an adapter with an SDS-plus shank and a 1/2" external square drive end. It lets a rotary hammer take socket wrenches - without it there is no connection between the machine and the socket.

What it solves

The rotary hammer is the most powerful rotating machine on site, but its chuck accepts only SDS-plus shanks. When anchors, threaded rod, coach screws or scaffold bolts need tightening, it is the natural tool for the job - it has torque a drill driver does not. The adapter is the missing link: one end goes into the SDS-plus chuck, the other presents a standard 1/2" square that any socket fits.

Material and durability

The adapter is made of modified S2 steel with an optimised heat treatment. That is not marketing: the adapter is the thinnest point in the machine-socket-bolt chain and carries the hammer's full torque. Soft steel twists and the square rounds off, after which sockets start to wobble and fall away. S2 is the steel impact bits are made from, and it stands up to extended work at high torque.

Socket retention

The square carries a spring-loaded detent ball that engages the groove in the socket. The socket pushes on and pulls off - it does not drop when working overhead, and it does not stay behind on the bolt when you pull the machine away.

Important in use

The rotary hammer must be set to rotation only, hammering off. The hammer action is meant to break concrete, not to pound on the adapter's square - with the hammer engaged you destroy the adapter, the socket and the bolt head alike. Most rotary hammers have a separate switch position for exactly this.

Who it is for

The adapter is for installers, scaffolders and site crews - anywhere large fasteners are worked and the rotary hammer is already in hand. It fits all SDS-plus rotary hammers, whatever the brand.
