What is an air hammer?

An air hammer is a member of a family of power tools that use compressed air to drive a circular percussion mechanism. In turn, the redundant impact force of this mechanism is transferred to a drill or chisel. Air hammers are used to drill, break down or make tough materials such as concrete, asphalt or tile. Air-powered air hammer are usually large tools used in heavy-duty construction, mining, and geological exploration sometimes smaller in handyman tool kits.

Impact-powered tools such as fleas and rock drills have been in use for centuries and were powered by muscle sweat and hammers before the introduction of pneumatics. Pneumatic hammers, commonly referred to as rock drills, have revolutionized construction and mining with single operator operation and high speed. As related technologies became more prevalent, they became more reliable, quieter, and smaller, and the potential applications of tools expanded to domestic and hobby light industrial applications. Today, air hammers are commonly used, from drilling holes in hard rock to shaving tiles in homes.

The pneumatic hammer mechanism is a relatively simple arrangement driven by compressed air. The impact is transmitted by a piston-driven back and forth by compressed air. The piston has a percussion head that hits the head like a chisel or socket drill with each forward stroke. This effect pushes the tool socket and tool bit forward and holds the work piece. A strong spring returns the tool socket to its original position and is ready for the next drag.

The quick, repetitive hammering action of this tool bit can break or drill into hard concrete and shorten the work of softer materials. A variety of tool bits, such as tipped, spade, scrabbler, and pile driver bits may be used depending on the specific application. The pneumatic air hammer bits mechanism is simple, reliable, and requires little maintenance. Most are equipped with an internal lubrication system driven by a percussion circuit. As long as the lubricant is supplied, there will be little glitches in these rugged tools.

However, the Jackhammer operator is not as strong as it could be. Personal protective equipment (PPE) such as gloves, respirator, and eye and ear protection should be used at all times. These tools produce fine dust and debris when working with hard materials such as concrete. They are not the quietest of devices and transfer intense vibrations through the handlebars. The use of PPE is essential in preventing hearing loss, eye damage, carpal tunnel syndrome, and peripheral blood flow hand.

What is a jackhammer?

The word “hammer” is used in northern American English and Australia, on the other hand, the “pneumatic drill” is used in the English-speaking world commonly in other areas; however in the strict sense of the word a “jackhammer “means a pneumatically actuated jackhammer.

What is it used for?

A portable drill is useful for use against steep walls and slopes, except for a strong person, because the user must analyze how much force, support, and trust are required to execute the blow. One method developed by experienced workers is to carry out the work with a group of two men to overcome the difficulty posed by gravity: the idea is that one man operates the hammer and the other two assist by holding the hammer, either on the shoulders or leaning on his arms. The combined weight allows the bit to be pushed into the workforce. This technique is known as horizontal jackhammering.

Hammer classes

Pneumatic hammer: A pneumatic hammer or drill is a pneumatic hammer that uses compressed air as a power source. The air supply comes from a portable air compressor that is powered by a diesel engine. The equipment is made up of a driven reciprocating compressor that allows air to pass through a centrifugal clutch, by a diesel engine. The engine governor operates at two speeds: At idle, when the clutch disengages, and maximum, when the clutch concentrates and the compressor runs. Current versions use rotary compressors and have more specialized versatile governors. The equipment is usually trailer mounted and sometimes includes an electric generator to provide the lights or power tools.

Electromechanical or Electro-Pneumatic Hammer: These types of hammers come in a wide variety of sizes from 12 pounds to 65 pounds. These instruments require an external power source but do not need a compressor. These power tools are indispensable for places where the entry for a compressor is difficult or impractical, such as inside a building, in a crowded construction zone, or in a remote location.

Hydraulic Hammers: Hydraulic hammers are generally larger than portable hammers and are often equipped with a mechanical excavator or backhoe. It is used for road construction, quarry, demolition work and general base construction. These large machines are known as rig mounts or machine mount breakers. This class of tools is also used for vertical walls. This is because the associated vehicle is large and powerful enough to generate the associated force without the need for gravity help to run the tool.


The pneumatic hammer works by driving an “internal” hammer up and down, that is, its mechanism moves down to hit the rear and then returns to the original position.

Inside the hammer, there is an air tube circuit, an impeller, and a bit. Air enters from the compressor under high pressure and moves the bit downward, causing it to hit the ground.

The valve inside the circuit makes the air go in the opposite direction. Then it is turned over again and the process is repeated. For this reason, the hammer is able to crash into the bit more than 25 times per second, hence it is so powerful and efficient.

These types of hammers are not only used in construction because they are a quick way to break stone. They are even recommended in emergency situations when you need to break through the rubble.
