These specialized tool accessories are designed for rotary hammer drills, specifically those utilizing the SDS Max shank system. They are primarily employed for drilling and chiseling into concrete, masonry, and similar hard materials. For example, a construction worker might use one to create holes for anchoring bolts in a concrete foundation.
Their importance lies in their efficiency and durability when working with tough materials. The SDS Max system allows for a larger shank size, providing greater impact energy transfer and enabling faster drilling and chiseling speeds compared to smaller shank systems. This translates to increased productivity and reduced wear on the tool and accessory. Developed as an evolution of earlier shank systems, they represent an advancement in power tool technology, optimizing performance for demanding applications.
