Why This Tool Is Worth It
The CORE18V 4 Ah battery is built to deliver more power without adding bulk. It weighs just 1.10 lbs.
Bosch rates it at 2x the runtime and 60% more power than its BAT612 18V 2 Ah battery. That’s enough for drilling into concrete, metal, and wood, plus grinding, cutting, and light chipping.
CoolPack 2.0 technology helps keep the battery cool, which Bosch says leads to longer battery life compared to its non CoolPack 18V packs.
