The Bosch Core18V 1" Bulldog Rotary Hammer Kit with Dust Collection (GBH18V-26K24GDE) pairs two top of the line Core18V batteries with the 1" SDS Bulldog Rotary Hammer and includes a fast charger to keep you going for longer. It delivers more power in a lighter weight package than previous iterations. The included dust collection attachment provides a self-contained HEPA dust solution for maximum mobility. In Bosch's tests, the Bulldog Rotary Hammer with an Core18V battery can deliver up to 32% more holes than previous generation tools with 1.9 foot pounds of impact energy. Built in KickBack control prevents the tool from spinning in bind up situations which helps to protect the user, the tool, and the material being worked. Electronic Precision Control and Vibration Control also improve user comfort. This hammer kit works with Bosch PRO+GUARD dust solutions – an end-to-end dust-collection system that helps users move toward OSHA Silica Table 1 dust compliance.
