How Does An Air Hammer Work

By Herbert Dorman

An air hammer is a pneumatic device mostly used in construction sites. It uses compressed air for carving metals, stones, among other materials. Generally, this tool is useful for making holes, shaping metals, and smoothening surface areas of various materials like wood, cardboard, grills, and concrete. Therefore, it is crucial for beginners with the desire to know how does an air hammer work to read through this article for their perfect start. 

The compressed air is very critical for the performance of this hammer in the workplace. It enables users to work on the surface of a material, twist, or bolts hammer faster than other conventional models. This is possible because these devices come in different sizes and shapes depending on the nature of work that needs an operation.

 

Tools Used In The Air Hammer

An air hammer is a handy device valuable for its speed but may lack a precision bit in the outcome. The compact design of this model is necessary to withstand not only the quantity of work but also any scope of operation. There are various tools used in this tool to strengthen its drilling ability:

  • Ball joints
  • Shock absorber chisel
  • Exhaust paper cutter
  • Tapered punch
  • Rubber pushing splitter
  • Parts of an air hammer

 

Parts Of An Air Hammer 

The construction of the air hammer constitutes chisel, accessories, and bits that are useful for cutting and scoring different types of workpiece. Knowing about the parts of this tool is imperative for a better understanding of its proper functioning.

 

  • Piston 

Air hammers come with a piston that moves forth and back for better circulation of the compressed air within the cylinder. The circulation of air continues for a long time, making the device relatively faster and perfect, unlike old tools and procedures. It is necessary to note that the air compressed is the major component and source of energy supply in the air hammer.

 

  • Air inlet 

The Air inlet is a shaft in the hammer connected to the tube of pressurized air. With the air connector, you can fit the compressed air tube correctly into the inlet. 

 

  • Trigger

The air hammer comes with a small button situated to its inner rear section handle and is useful for turning off the tool. Placing this button is simply for comfort and preventing the use against bodily harm.

 

  • Regulator

A regulator is a small switch at the air hammer’s rear handle used for regulating air pressure. The button on the regulator is essential for increasing and decreasing the quantity of pressure according to the type of work.

 

  • Spring

The attachment of the spring located in the air hammer to its cylinder helps in keeping the chisel in shape, which is an aspect known as retainer spring. Accordingly, the spring opens in the direction anticlockwise for better locking and unlocking when fitting into the chisel.

 

  • Cylinder

Generally, the cylinder nose of this critical device and is useful for bits and chisel attachment. It is also the next place individuals can hold firmly when the air hammer is in use. 

 

Steps On How To Use An Air Hammer

Air hammers may range from compact size to commercial lager size depending on the amount of work available. Having known about an air hammer, now I can take you through various steps on how to use your air hammer correctly and safely.

Work surface

You require to make sure that the working surface is devoid of debris, clean, and lit properly. Layout the compressed air tube properly to prevent it from tripping. Notably, please do not use this tool close to highly flammable materials since it is potent. Accordingly, it is necessary to wear safety gear such as hear and eye protection before starting the operation.

 

Ascertain the number of bits required for the job

The tip selection for the job depends on the amount of work at hand. Additionally, there is a need for you to make sure that the bit selected is immaculate and sharp for performance enhancement. When the machine is new, you need to find out whether the box contains the essential tip. Similarly, you need to purchase the correct bit if it is missing in the box.

Inspecting the bit for sharpness is another thing in case you have utilized an air hammer previously. Avoid using blunt tips as they can make the machine to clump up and give uneven outcomes. It can also lead to time-consuming and air wastage. Therefore, sharpening and cleaning your bit in advance is vital for the perfect performance.

 

Insert and lubricate the bit into the cylinder

Lubricating the air hammer before the drilling process is vital since it helps to improve the operation. Use 2-3 drops of oil for a news chisel to minimize friction during the procedure. Similarly, it is essential to use a thin oil film when assembling the air hammer to prevent faster wear and tear and friction.

It is also essential to add some drops of oil per hour if you are using the device for an extended period. Besides, you need to check the recommended type of oil required in the manual for better lubrication.

 

Unscrew the spring 

The next step is unscrewing the retainer spring and inserting the bit into the nose of a cylinder. Then, screw the retainer spring back for stable attachment of the bit. It is crucial to confirm the appropriate way of inserting the bit from your manual to avoid the use of inconveniences. However, there are subtle differences from one tool to the next, even though their workings are the same fundamentally. 

 

Connect the Air Hammer to the compressed Air Tank

Choose the appropriate connector to avoid leakages when the air hammer is in use. This involves purchasing the model that contains the air connecters. However, many cheaper brands available in the market do not come while air connectors included. Do not use compressed air that is more than 200 psi to prevent the tool from exploding.

 

Power up an Air Hammer

Powering up the air hammer is the next step after attaching it properly to a compressed air tank. This occurs after ensuring that the working area is clear and proper clamping of any materials that need stability. Place one hand around the handle and the next on the cylinder to ensure simple adjustment of the air hammer, strength, and comfortable operation.

 

Final Verdict

An air hammer is a tool that every household must own. With this tool, DIY enthusiasts can perform demolition activities efficiently and within a short period. Do not forget to wear protective gear to prevent your eyes against solid particles and hearing impairment. If you are confused still, then our top selection on air hammer content will help you to get rid of how an air hammer works.
