The primary use of a jackhammer is to break up rock-like materials. They were first used to break apart rocks in mining operations. Then, they were used to help construct tunnels as they could break up the rocks that normal digging tools would have a difficult time removing. Today, they are mostly used to break apart concrete and asphalt …

When it comes to a hammer drill's performance, there are two numbers to consider: the speed and the impact. The speed of a hammer drill refers to how quickly the bit spins and is measured in rotations-per-minute (rpm). Many hammer drills have variable-speed triggers or dials, but some of these tools have only a single speed setting or a ...

Energy output, often referred to as the "energy class", indicates the amount of energy the hammer delivers with each blow. It is typically measured in foot-pounds or joules. It determines the hammer's breaking power. A higher energy output means the hammer can break tougher materials more effectively.

What is Impact Energy? Impact energy is the force generated by a jack hammer when it strikes a surface. It is a measure of the tool's ability to break through materials. This energy is typically measured in joules (J) or foot-pounds (ft-lb), providing a quantifiable metric for the tool's effectiveness.

The speed vs torque "curve" in cordless impact drivers and impact wrenches works differently. Given full power to the motor, an impact tool produces more speed to the rotating anvil. That additional speed on the anvil produces more impacts—and thus more torque. On a multi-speed impact tool, to get the most torque you would set it …

Hammer drills are great time savers when you're drilling holes in dense materials like masonry or concrete, as well as wood. Hammer drills add a forward action, repeatedly driving the drill bit in and out of the work material. It works fast, often 20,000 to 60,000 beats per minute (bpm). This additional force pushes the bit through tough …
