SDS-max® Hammers

SDS Max hammers are built for heavy-duty drilling and chiseling in tough materials such as concrete and masonry. They are often used in large-scale construction projects for applications like drilling oversized anchor holes, installing rebar, or breaking through concrete slabs and walls.

SDS Max hammers are typically designed for higher-demand applications, offering greater impact energy and using larger 18 mm shanks. In contrast, SDS Plus hammers have smaller 10 mm shanks and are generally suited for lighter or medium-duty jobs. The choice between the two depends on the scale and intensity of the task.

Yes, most SDS Max hammers include chiseling functionality, making them well-suited for demolition tasks such as removing tile, chipping over-poured concrete, or breaking down concrete walls and floors.

Bosch offers SDS Max hammers in both corded and cordless 18V configurations. Cordless models—often part of the PROFACTOR™ lineup—provide increased flexibility on jobsites where access to power may be limited.

Depending on the model, Bosch SDS Max hammers can support bit diameters ranging from 1-9/16" up to 2", accommodating a wide range of drilling needs in concrete and other dense materials.

The SDS Max system uses a slotted drive mechanism to allow for fast, secure bit changes without the need for additional tools. Originally developed by Bosch in 1975, this system is designed to streamline heavy-duty work by improving bit retention and reducing downtime.
