construction work using a jackhammer for heavy-duty tasks ...

The 7 degree refers to the angle at which the cutting edge of the button bit is set. This particular angle is not arbitrary; it is a result of meticulous research and development by engineers to optimize performance and durability. It strikes an ideal balance between penetration rate, wear resistance, and chip removal, making it a preferred choice for drilling hard materials like rock, concrete, and even metal.

One of the most important factors to consider when choosing a jackhammer is its power source. Jackhammers can be powered by electricity, gas, or pneumatic power, each with its own set of advantages and disadvantages. Electric jackhammers are generally lighter and more portable, making them ideal for indoor use or smaller projects. Gas-powered jackhammers are more powerful and durable, but they can be heavier and less portable. Pneumatic jackhammers are also powerful and durable, but they require a constant supply of compressed air, which can be inconvenient.
