Bosch Hammer Drill Kit GSB18V-975CB25 18V Brushless Driver (1/2 Keyless Chuck 975 In-Lbs Torque Two 4Ah CORE18V Batteries Charger Bag Fastening)

Contractor-Grade 18V Brushless 1/2-Inch Hammering Tool System for High-Torque Foundation Anchor Drilling and KickBack Protection

The Bosch GSB18V-975CB25 18V Brushless Connected-Ready 1/2-Inch Hammer Drill Driver Kit delivers professional-grade mechanical drilling velocity and high-torque fastening under severe jobsite loads. Engineered with a high-efficiency brushless motor, this complete cordless system minimizes rotational surface resistance while outputting a massive 975 In.-Lbs. of maximum torque and up to 31,500 beats per minute (BPM) for fast penetration in structural concrete, masonry, and hardwood. The compact, balanced housing integrates an active sensor-based KickBack Control system that instantly cuts power during sudden bit bind-ups, solving the physical strain and wrist injury problems common in deep wood boring. Supplied with two CORE18V 4 Ah Advanced Power Batteries featuring CoolPack 2.0 thermal regulation, this high-performance system operates at high capacity while maintaining an agile tool footprint of only 3.4 lbs.

Best Used For:

• Structural Concrete Anchor Boring: Drilling high-speed tapcons, sleeve anchors, and conduit pass-through openings in concrete block foundations using percussion hammer mode.
• Heavy-Duty Timber Fastening: Driving large ledger screws, structural lag bolts, and self-tapping metal fasteners cleanly into framing timbers and multi-ply beams.
• Large Diameter Hole Sawing: Running aggressive wood spade bits, auger bits, and multi-material hole saws through dense dimensional framing headers.

Key Performance & Safety Features

• Brushless Motor Technology: Maximizes runtime and tool longevity while generating up to 975 In.-Lbs. of contractor-grade maximum torque.
• Active KickBack Control: Integrated electronic sensor reduces sudden rotational torque reactions during unexpected bind-up scenarios, protecting the user.
• CoolPack 2.0 Heat Management: Advanced battery shell structure houses high-power Li-ion cells to manage heat dissipation, extending total life and runtime.
• Heavy-Duty All-Metal Chuck: 1/2-inch keyless chuck delivers premium bit grip pressure to prevent slippage during high-stress percussion drilling.
• Rapid Mode Selector: Dedicated toggle allows instant shifting between hammer drilling and driving modes without losing your custom clutch parameters.
• Connected-Ready System: Compatible with an optional GCY42 Bluetooth module to customize tool parameters and receive feedback via the Bosch PRO360 app.

Technical Specifications

Pro-Tip: When deploying the 31,500 BPM percussive action in high-density aggregate surfaces, lock the side-assist handle perpendicular to the tool body. Maintain flat inline pressure along the center line axis to let the percussion hammer advance the bit without generating thermal stress inside the steel core chuck gear.
