Abstract: An electric hammer is an electric rotary hammer drill with a safety clutch and a pneumatic hammering mechanism. It uses piston movement and compressed gas to impact the drill bit on hard materials such as concrete, bricks, and stones. 6--100mm hole. There are many models of electric hammers, and different models have different features. What models of electric hammers are there? How powerful is the electric hammer? How to choose an electric hammer drill bit? Electric hammer models: Which electric hammer models match drill bits

There are different models of electric hammers. Different models have different scopes of use and methods of use. Next, let’s take a look at the differences between different electric hammer models, what the different letters on the electric hammer model code mean, and the issues related to matching different electric hammer models with drill bits.

1. Electric hammer models are divided into E, RE, DFR and DRE. What are the differences between them?

There are many models of electric hammers, such as the Bosch GBH2-26, which is divided into several different models such as GBH2-26E, GBH2-26RE, GBH2-26DFR and GBH2-26DRE. The prices vary by hundreds. bucks. So, what are the differences between these models and what do the different letters stand for?

1. The first letter indicates the type of electric hammer:

G=Professional grade (GBH2-22RE)

P=Household grade (PBS75A)

p>

A=Garden tool (ART30Combitrim)

2. The second and third letters indicate the type of electric hammer

BM=Electric drill (GBM350RE)

< p>SB=impact drill (GSB13RE)

BH=electric hammer (GBH2-22RE)

SH=electric pick (GSH388X)

SR=rechargeable Screwdriver (GSR9.6-2)

WS=angle grinder (GWS7-125)

ST=jigsaw (GST65E)

HO=electric Planing (GHO10-82)

HG=Hot air gun (GHG500-2)

DM=Marble machine (GDM13-34)

3. Fourth The numbers after the digits indicate the main parameters of the electric hammer

Kilogram grade (GBH2-22S)

Power (GBM350RE)

Maximum processing diameter (GBH2-26RE)< /p>

Several gears of mechanical speed regulation (GBM13-2RE)

Voltage (charging tool) (GSR9.6-1)

Sawing capacity (GST54E)

p>

Disc diameter (GWS14-150CI)

4. The suffix letter indicates the individual function of this electric hammer

R=forward and reverse (GSB550RE)

E=Electronic stepless speed regulation (GSB550RE)

A=Dust collection function (GSS280A)

P=Swing function (GST85PBE)

B=Arc handle (GWS24-180B)

V=Voltage (charging tool) (GSR7.2V)

C=Constant speed control (GWS8_100CE)

L=Long arm straight grinder (GGS27L)

S=Flat drilling function (GBH2-24DSR)

D=Gouge function (GBH5_38D)

F=Chuck replacement (GBH4DFE)

X=Hexagonal drill/chisel bit (GBH5-38X)

2. Different electric hammer models and matching drill bit specifications

< p>1. Take the round-shank four-pit electric hammer as an example. It can only be equipped with a round-shank four-pit drill bit (ie: SDS-Plus standard). As for the round-shank four-pit drill bit, although the working part is different in thickness and length, its handle is exactly the same and can be installed on the electric hammer. In other words, a No. 5 small drill bit can be installed on a 30-inch large electric hammer, and a 22-inch large drill bit can also be installed on an 18-inch small electric hammer.

2. It is best not to bring a large drill bit with a small electric hammer. 24, 26, and 28 electric hammers can carry 24, 26, and 28 drill bits at most. It’s okay to have a small drill bit, but it shouldn’t be larger than the electric hammer’s mark. If it’s too big, it will burn out the motor. It should be noted that the actual drill bit selected should be 4 or more sizes smaller than the electric hammer.

3. The largest model of a four-pit electric hammer is 32, but the largest four-pit drill bit in the world is only 22, and larger ones are not produced. So, wouldn’t a four-pit electric hammer with a rating of 24 or more be a waste of power? No. The bigger the electric hammer, the better. How many are suitable? Generally not less than 4. It depends on where the holes are drilled and how frequently they are used. If you drill 22mm holes in the reinforced concrete wall every day, a 30cm electric hammer is not too big.

Different models of electric hammers have different scopes, methods, and drill bits. Everyone must pay attention to understanding them clearly during use. Otherwise, it may bring some serious consequences, not only affecting the construction quality, but also causing danger.
