What is the difference between 4-pit-electric hammer and 5-pit-electric hammer?
Four-pit electric hammer: It means that the number of slots at the electric hammer drill shank is four pits, divided into two keyways and two steel ball slots, which are used on the four-pit electric hammer. This drill is generally used on medium-sized hammers.
Five-pit electric hammer: It means that the number of slots at the electric hammer drill shank is five pits, divided into three keyways and two steel ball slots, which are used on the five-pit electric hammer. This drill is generally used on heavy duty hammers.
The differences between two electric hammers:
1. The four-hole electric hammer is the longest used on the market. There are some small places in the five-hole electric hammer that will not be equipped with drill bits.
2, Five pit electric hammer is generally used on a large electric hammer, 38 or more. Because the large electric hammer has a large torque, the five-pit electric hammer is relatively more reasonable.
3, Five pit electric hammer is the patent of BOSCH. To produce this kind of electric hammer, you can buy a patent from BOSCH. Four-hole electric hammer can be bought everywhere.
