              The Astro Pneumatic Tool 4980 is a “big nasty” powerful, super-duty, durable air hammer and riveter combined.

              It is designed for drilling, punching, hammering, chipping, and cutting as well as sanding and spraying. The 4980 can capably remove or install I-beam suspension rivets and heavy-duty equipment and truck springs, bushings, king pins and more faster and easier.

              The 4980 is harder-hitting than most of its competitors. Its heavy-duty, durable, dual purpose design aids production and comfort to reduce fatigue. It has a spring retainer for faster chisel bit changes.

              The Astro Pneumatic Tool 4980’s ¼” air inlet and ⅜” size hose ensure maximum air flow/pressure. Specifically, the 4980 is 4.8 pounds, measures 12 inches long, has a ¾” bore, and an extra-large 0.498 in. tool shaft/shank for automotive, heavy-duty, off-road, or industrial applications. It offers a 2-11/16” (2.69 in.) piston stroke and it delivers 1,800 blows per minute (BPM).

              Runner up: Sunex SX243 Long Barrel Air Hammer

              Sunex SX243 Long Barrel Air Hammer
              Sunex SX243 Long Barrel Air Hammer
              Pros
              • Long barrel design
              • Aluminium alloy housing
              • Built-in regulator
              Cons
              • Does not come with any chisels
              • No carrying case included

              The Sunex SX243 air hammer combines high power with a lightweight design. This is mostly due to the aluminum casing which reduces the total weight of the model to just .48 ounces. However, it does have some parts reinforced with steel, for durability’s sake. Despite its small housing, the bigger part of the hammer is the barrel, making this model a long-barrel one. So, this Sunex model can tackle heavy-duty tasks.

              You can punch, chip, or cut into stone and metals with the SX243 that delivers up to 2,200 blows per minute (BPM), which is a little less than our top choice but still gets the job done. Large projects get done in record time without any of the usual hassles that are familiar with traditional hammers.

              High efficiency and durability are injected into the design of the SX243, with a ¾-inch bore diameter and a 3 ¾-inch piston stroke length. With a stroke length that high, you can expect higher velocity from the piston and more power delivered to the chisel.

              Air Hammer Buying Guide

              Most air hammers can be fitted with a variety of tips. These include hammer tips, for shaping and smoothing, and chisel tips, for scoring or cutting. Pneumatic tools are rated using several metrics: Free Speed (RPM), Air Pressure (psi/bar), Air Consumption (cfm/scfm or m3/min), Horse Power (hp), and spindle size. Each individual tool has its own specific requirements which determine their compatibility with air compressor systems.

              Before buying an air hammer, consider these important factors:

              • Blows Per Minute (BPM): BPM is the number of those cycles that piston pushes it to hit the hammer and return it per minute. Compressed air enters the barrel and makes the piston go back and forth for several thousand times in a single minute. The lower the number of BPM the stronger the impact of the hammer;
              • Revolutions Per Minute (RPM): is a measure of the frequency of a rotation. It states the number of full rotations completed in one minute around a fixed axis. It is used as a measure of rotational speed of a mechanical component. In other words it is how many times something rotates every minute. It is used as a measure of how fast a mechanism is turning. So if a motor is turning at 100 rpm it means that for every minute the motor is running it makes 100 complete turns.
              • Barrel size: To accommodate pistons with a certain stroke length, an air hammer can have a short barrel, a medium barrel, or a long barrel.
                • Short barreled air hammers with low cfm are suitable for light work that require dexterity and control rather than sheer power, such as cutting through sheet metal and body panels.
                • Medium and long-barrel air impact hammers are suitable for heavy-duty tasks.They tend to be heavier, and are often more powerful, harder to control, and prone to more vibration and louder operation.
              • Stroke length: Stroke length is the distance the piston travels with each cycle, and this figure is usually given in terms of inches. A typical, medium-duty air hammer will have a stroke length of 2-5/8 inches and can go up to 3 inches. The longer the stroke length, the higher the velocity that the piston can achieve at the end of one stroke cycle, and the more power it can deliver to the chisel.
              • Compressor/Tank Size: An air compressor and air hammer perform professional work, maintenance, and repair tasks easier and faster. Compressor tank size, motor horsepower (hp), air volume output (CFM), and air pressure (psi) must be sufficient to operate the air hammer. The volume of air the compressor can produce (CFM) and the air pressure contained in the tank (psi) are the most important considerations. These specifications are typically marked on the tank’s label. Each air impact hammer requires a minimal CFM (cubic feet per minute) at a prescribed psi (pounds per square inch) to properly operate at full efficiency.

              Most air hammers/chisels require around 4 cfm of airflow to operate on a continuous basis.

              • Attachments: (hammer and/or chisel tips included or optional)

              Conclusion

              Like most power tools, an air hammer is a powerful tool packed into a handy kit. Do not underestimate an air hammer – the pressure it can exert will easily cause serious harm, especially with a sharp chisel attached.

              Always wear protective eye gear and gloves when working with air hammers, especially if you are cutting or chiseling metal or stone. Never operate an air hammer in areas with suspended dust, combustible gas, or any area where a spark can trigger an explosion.
