Difference Between Hammer Drill and Drill

Hammer Drill vs Drill

All of us are aware of what a drill is. It is a device that has a tool attached at one end that rotates at great speed and is used to making holes in surfaces mainly to either place a nail or to fasten two surfaces through screws. Drill is one tool that carpenters and electricians invariably use as they often need to make holes in surfaces. But a drill is a multipurpose tool that comes handy in homes in daily life also. Two types of drills are popular, namely ordinary rotary drill and other known as hammer drill. People remain confused between these two and cannot seem to decide on one or the other. This article will explain the features of both types of drills to enable the reader to choose one or the other depending upon his requirements.

A standard drill, whether manual or electric, rotates the drill bit clockwise or counterclockwise. Its twisting motion penetrates into the surface removing some part thus causing a hole into it. The drill works well on semi porous surfaces. All the pressure is created by spinning motion and the bit goes deep inside the surface you are drilling to create the hole that 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 require making 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 simple drill, it also moves back and forth apart from spinning in the case of hammer drill. This short hammer thrust pulverizes the brittle material and makes drilling easier than with an ordinary drill and one can make holes with lesser effort with hammer drill than with a simple drill.
