Bosch EXPERT SDS plus-7X Hammer Drill Bit 12 x 100 x 165 mm

The Bosch EXPERT SDS plus-7X hammer drill bit, 12 mm, is a one-piece carbide hammer drill bit for heavy-duty rotary drilling. It handles demanding masonry work, including standard concrete and natural stone. Contractors use it for continuous rotary hammer operations where other bits tend to fail. It also performs well in reinforced concrete, remaining stable when it meets embedded steel rebar. On site, it drills efficiently into hard, unyielding surfaces. Professionals use it to produce accurate holes for structural anchors and heavy fixtures.

An SDS plus shank fits directly into compatible rotary hammers, giving a secure drive without the need for a separate chuck adapter. The base design uses the SDS system to lock firmly into the power tool, handling high-torque impacts safely. The standard grey finish gives the bit a conventional industrial look suited to construction work. The heavy-impact hammer-drilling design lets the bit penetrate dense materials consistently. The specialised head reduces the risk of the bit jamming or needing frequent repositioning during demanding masonry tasks, which helps keep hole production reliable through tough, reinforced structural elements.

• 12 mm drill bit diameter for standard masonry anchoring and installation work.
• 100 mm working length, the maximum hole depth achievable in a single continuous pass.
• 165 mm overall length for adequate reach and clearance in standard wall penetration.
• 4-cutter head design that helps prevent jamming when striking steel reinforcement.
• Compatible with both rotary drilling and hammer drilling for use across varying concrete densities.
