Bosch EXPERT SDS plus-7X Hammer Drill Bit 16 x 250 / 315 millimetres

The Bosch Expert SDS plus-7X hammer drill bit is a one-piece carbide hammer drill bit built for high-stress masonry applications. It is rated for hammer drilling into solid concrete, reinforced concrete, and stone. A solid carbide head resists rapid wear when striking reinforcement bars in structural walls. Designed for trade use, it performs reliably under continuous high-impact conditions. It relies on the hammering mechanism of a compatible rotary drill to break through dense materials. Installers working with tough mineral substrates benefit from its durability during extended drilling runs.

Finished in a standard grey colour, the bit connects directly to compatible SDS plus chucks without needing an adapter. The shank locks securely into place, allowing efficient transfer of impact energy from the machine. Slotted grooves on the shank let the bit slide axially during operation, which is required for proper percussion action. It remains firmly held in the tool chuck even during demanding masonry drilling. This mechanical fit allows for quick, tool-free bit changes between jobs. To function as intended, the bit must be used with a dedicated electric rotary hammer drill.

• 16 mm drilling diameter creates appropriately sized holes for structural anchors and large fixings.
• 315 mm overall length provides extended reach for drilling through thick masonry walls.
• 250 mm working length allows deep anchor installations before the chuck meets the surface.
• 4-cutter head geometry maintains steady chip removal and reduces the risk of jamming on steel rebar.
• SDS plus shank shape ensures direct compatibility with standard electric rotary hammer drills.
