What is a Drill? A Beginner’s Guide to a Popular Tool

As Pros, there aren’t a ton of people in our office asking, “what is a drill?” But if you’re new to the world of power tools or just looking for a better understanding, who better to explain it than guys and gals that use them every day?

What is a Drill? The Textbook Definition

What is a Drill? A Beginner's Guide to a Popular ToolMerriam-Webster defines a drill in different ways. We’re not talking military drills or the act of drilling, we’re talking tools. They define it as:

“An instrument with an edged or pointed end for making holes in hard substances by revolving or a succession of blows.”

Fundamentally, that’s dead on. A drill has some sort of point or edge (a drill bit) that turns. In most cases, it shaves away material to create a hole, but it can also chip through or use a combination of the two.

It’s also a very wide definition. Drills can be small enough to make near-microscopic holes or large enough to dig a tunnel under the English Channel.

Quick History of the Drill

What is a drill? That depends on what period of history you’re looking at. Historians estimate humans figured out how to rotate a pointed stone against another object to make a hole some 35,000 years ago.

A little more than 200 years ago, we see the first picture of a beater-style hand drill, though its specific invention date is not clear.

When it comes to adding electricity, Arthur James Arnot and William Blanch Brain of Australia get credit for inventing the first electric drill way back in 1889.

The first portable handheld drill came from the minds of Wilhelm and Carl Fein in Stuttgart, Germany in 1895 – the very same Feins whose company dominates the oscillating multi-tool market today.

In 1917, Black & Decker patented what we might call the “modern drill” with a pistol grip style and trigger.

The first cordless drill made its appearance in 1961. Black & Decker used a nickel-cadmium battery to power it.

Back to the Present

When most people think of drills, they think of the pistol grip type that Black & Decker invented with either a corded or battery power source.

In either case, an electric motor turns the chuck, which holds a drill or driver bit. The rotation allows a drill bit to slice material away or a driver bit to install/remove a fastener. In case it comes up on Final Jeopardy, most of the “drills” we use today are actually drill drivers since they can both drill holes and drive fasteners.

Even though the most popular drills are the handheld type we use for general drilling and fastening, many other types exist. No matter what you need to make a hole in, chances are there’s a drill for that. Here’s a pretty good list to start with:

  • Drill Press
  • Core Drill
  • Hammer Drill
  • Rotary Hammer Drill
  • Magnetic Drill
  • Ground Auger
