Hand drills and impact drills are two common types of power tools that are very similar in use but have some differences.
A hand drill is a power tool used for drilling, usually for light drilling work, such as drilling holes in materials such as wood, metal, and plastic. Hand drills usually come with a drill chuck that can hold drills of different sizes.
An impact drill is an electric tool that can apply impact force to hard materials such as brick, concrete, and stone.
In addition, there are other differences between hand and impact drills. Hammer drills tend to be heavier than hand drills due to internal mechanism that creates impact. In addition, since drill bit of an impact drill rotates and vibrates at the same time, a longer drill bit must be used to ensure sufficient drilling depth.
In practice, hammer drills are often better suited for drilling in hard materials or concrete. And for lighter drilling jobs, a hand drill is better.
In addition, it should be noted that when using a hand drill or impact drill, be sure to wear personal protective equipment such as goggles and ear plugs to protect your safety and health.
