My tooth is throbbing like a jackhammer. Mein Zahn pocht wie ein Presslufthammer. And on the last day with this female where I thought I had pushed her too far, I got nervous because she came up to me, she rolled over on her back, and she did this deep, guttural jackhammer sound, this gok-gok-gok-gok.

Und am letzten Tag mit diesem Weibchen, als ich dachte, ich hätte es zu weit mit ihr getrieben, wurde ich nervös, denn sie kam auf mich zu, rollte sich auf ihren Rücken und gab diese tiefen, gutturalen Presslufthammertöne von sich, dieses gokgokgokgok.

An electropneumatic hammer is often called a rotary hammer, because it has an electric motor, which rotates a crank.

The hammer has two pistons — a drive piston and a free flight piston. The crank moves the drive piston back and forth in the same cylinder as the flight piston.

The drive piston never touches the flight piston. Instead the drive piston compresses air in the cylinder, which then propels the flight piston against a striker, which contacts the drill bit.

They require an external power source, but do not require a compressor. Although in the past these tools did not have the power of an air or pneumatic hammer, this is changing with newer brushless-motor tools coming close to the power of a pneumatic tool and in some cases even matching it.

Electric powered tools are useful for locations where access to a compressor is limited or impractical, such as inside a building, in a crowded construction site, or in a remote location and it is not uncommon under earth moving equipment or tool.

The connection end size is also related to the breaking energy of the tool. See hammer drills for more on electropneumatic hammering. A hydraulic jackhammer, generally much larger than portable ones, may be fitted to mechanical excavators or backhoes and is widely used for roadwork, quarrying and general demolition or construction groundwork.

Such tools can also be used against vertical walls or ceilings for that matter , since the vehicles involved are massive enough and powerful enough to exert the forces involved without needing the help of gravity in operating the tool.

Pneumatic or hydraulic tools are particularly likely to be used in mines where there is an explosion risk such as underground coal mines , since they lack any high-power electrical circuitry that might cause a triggering spark.

Hydraulic breakers usually use a hydraulic motor driving a sealed pneumatic hammer system, as a hydraulic hammer would develop a low strike speed and transfer unacceptable shock loads to the pump system.

Advances in technology have allowed for portable hydraulic breakers. The jackhammer is connected with hydraulic hoses to a portable hydraulic powerpack: either a petrol or diesel engine driving a hydraulic pump; or a mini-excavator or skid-steer via a power take-off driveshaft to the machine's hydraulic system.

Hydraulic power sources are more efficient than air compressors, making the kit smaller, cheaper or more powerful than a comparable pneumatic version.

Chisels may be resharpened in a shop or with an angle grinder with grinding disc. After resharpening, they must then be heat treated to restore the integrity of the steel before use.

Self-sharpening polygon and flat chisels are also available.
