Secondly, the size and power of the jack hammer play a crucial role in determining its cost. A larger, more powerful unit designed for heavy-duty applications will naturally be priced higher than a smaller model intended for lighter tasks. The power source, whether it's powered by compressed air or electricity, also impacts the price. Pneumatic models, which rely on compressed air, tend to be less expensive initially but require a continuous supply of compressed air, adding to the overall operational cost.

The choice of drill rod steel is crucial due to the harsh conditions it encounters. It needs to be strong enough to resist bending and breaking under immense pressure, while also being resilient against wear and tear caused by friction and abrasive materials. Typically, drill rod steel is composed of high-carbon alloy steels, often containing elements like manganese, chromium, and nickel to enhance strength, toughness, and resistance to corrosion.
