Bosch EXPERT SDS plus-7X Hammer Drill Bit 12 x 250 x 315 mm

The Bosch EXPERT SDS plus-7X Hammer Drill Bit is a one-piece carbide masonry drill intended for structural boring. It is designed for drilling into hard mineral materials such as concrete, reinforced concrete, and solid stone. It is typically used on site for heavy-duty work where consistent material removal is required. The bit is made for use in the hammer-drilling mode and transfers impact energy directly into the substrate. It handles embedded steel reinforcement without immediate tip failure. Finished boreholes provide a reliable base for mechanical fixings.

The SDS-Plus shank conforms to industry standards and fits directly into professional rotary hammers. It allows quick, tool-free bit changes and holds its position under high vibration. The main shaft has a neutral grey finish that provides basic protection against site conditions. At 168 g, the bit adds little weight to the hammer. The head geometry supports efficient material removal as the bore deepens, and reliable debris clearance keeps the cutters engaged with the workpiece.

• 12 mm drill bit diameter produces accurately sized holes for standard masonry wall anchors.
• 315 mm overall length gives extended reach for thicker walls and deeper structural fixings.
• 250 mm working length is the maximum continuous drilling depth per pass.
• 4-cutter head geometry reduces the risk of jamming when the tip hits embedded rebar.
• Solid carbide construction ensures a long service life under repeated heavy-duty use.
