We all know that a drill is a device with a rotating tool attached at one end, used for making holes in surfaces, mainly to place a nail or fasten two surfaces with screws. Drills are essential tools for carpenters and electricians, who often need to make holes in various surfaces. Drills are also useful multipurpose tools in daily life. There are two popular types of drills: the ordinary rotary drill and the hammer drill. People often find it difficult to choose between these two types of drills. This article will explain the features of both types of drills to help readers make a choice based on their requirements.
A standard drill, whether manual or electric, rotates the drill bit clockwise or counterclockwise. Its twisting motion penetrates the surface, removing some material and creating a hole. The drill works well on semi-porous surfaces. All the pressure is created by the spinning motion, and the bit goes deep inside the surface you are drilling to create the hole you want. A hammer drill not only spins the drill bit but also provides a tapping action to make the work easier. Imagine a hammering action at the same time while the bit is spinning. Hammering action is mainly required when you need to make a hole in a very hard surface, such as concrete or any other stone or tile. Another difference between a hammer drill and a simple drill is that while the bit only spins in a simple drill, it also moves back and forth apart from spinning in the case of a hammer drill. This short hammer thrust pulverizes the brittle material and makes drilling easier than with an ordinary drill, allowing you to make holes with less effort using a hammer drill than with a simple drill.
Key Takeaways
- Drills and hammer drills both create holes in surfaces, but hammer drills also include a hammering action with a bit that moves back and forth.
- Hammer drills are better suited for harder surfaces, such as concrete or stone.
- Using a hammer drill requires less effort to create holes than a simple drill.
