This Rotary Has Earned the ‘Hitman’ Title!
Introduction
BOSCH GBH18V-45CK27 1-7/8″ SDS Hitman Hammer
Welcome to the BOSCH GBH18V-45CK27 1-7/8″ SDS ‘Hitman’ Hammer Review,
The BOSCH GBH18V-45CK27 1-7/8″ SDS-MAX Rotary ‘HITMAN’ Hammer Drill has hit the ground running and Robert Bosch would be extremely impressed with its Technological attributes especially after releasing the first battery powered hammer drill in 1984.
Bosch has Hammer Drills in their History and the BOSCH GBH18V-45CK27 has evolved from their knowledge and innovation of this type of drill, as a result they have given us a Modern Rotary Hammer Drill nicknamed the “HITMAN”
In 1927 Bosch’s engineer Herman Stienhart was introduced to a different type of Tool, whilst testing new ideas and modern technologies of the time in the Bosch test workshop. He was given a new device the “Forfex” which had an integrated motor in it’s handle and his mind was instantly intrigued by the possibilities consequently, his department developed the “FireFox” over the next couple of years to create Bosch’s first Hammer drills.
