Description

Professional-Grade Hammer Drilling Power in an Ultra-Compact 12V Frame

The Bosch GSB12V-300B22 12V Max 3/8 In. Hammer Drill/Driver Kit is the ultimate solution for professionals who need high-performance masonry drilling and precision driving without the bulk of a full-sized tool. Engineered with a powerful brushless motor, this drill delivers an impressive 300 In.-Lbs. of torque and up to 26,250 BPM, making it ideal for boring through brick, block, and tough lumber. Its remarkably compact 6.7-inch head length and lightweight design (just 2.2 lbs. with battery) make it the perfect companion for long days of overhead electrical work, HVAC installations, or assembly in cramped cabinetry where standard drills simply won't fit.

This versatile kit offers complete control over every application with a two-speed transmission and 20+1 clutch settings, ensuring you can transition from high-torque driving to high-speed drilling without stripping fasteners. The industrial-strength three-jaw keyless chuck provides superior bit retention, while the integrated LED work light ensures your workspace stays visible in low-light environments. Complete with two 12V Max 2.0 Ah batteries, a charger, and a durable carrying bag, this kit provides the runtime and mobility required to tackle demanding tasks on any jobsite with professional-grade dependability.

Pro-Tip: When drilling into masonry or brick, use high speed and apply steady, firm pressure to let the hammer mechanism effectively pulverize the material. For delicate screwdriving in wood or plastic, switch to the lower gear and use the clutch settings to prevent over-driving and ensure a flush finish every time.
