Impact Driver Vs. Hammer Drill – What’s the Difference

What Is An Impact Driver?

An impact driver is a type of drill used to cut through concrete or other hard materials. These drills are typically large and heavy with multiple cutting heads mounted on one side of the tool. They have been around since the early 1900s. They were originally designed for mining and quarrying purposes but they are now being used in construction projects all over the world, especially in North America where they are most commonly found.

The advantage of using an impact driver is its versatility. While it may seem like a big and bulky tool, it does have several advantages. One of them is ease of use because the user doesn’t need to worry about getting into position quickly enough or reaching high enough to reach each individual part of the job site.

Another benefit is that these tools don’t require constant attention so they can be left in place while working at a different location.

Another advantage of an impact driver is its ability to cut through many types of material including wood, metal, plastic and even brick. Most impact drivers are made from steel or aluminum which makes them strong enough to handle the force needed to break up concrete. However, they do tend to get dirty easily so it is best if they are cleaned after every use.

How Does An Impact Driver Work?

Impact drivers contain a series of gears that are used to transfer the power from the motor. They also have a clutch that can be adjusted depending on what type of material you are working with.

The design of an impact driver transfers energy from the drill bit in pulses. This allows it to break through concrete, brick or any other material by transferring energy in one direction only (back and forth).

What Does An Impact Driver Look Like?

An impact driver typically consists of five major components:

1. Motor Housing: The housing is the main part of the tool where all the parts are attached.

It also contains the batteries and the motor at the bottom of the drill.

2. Chuck: This is the part that holds the drill bit.

Most impact drivers use a keyless chuck so changing bits is quick and easy.

3. Drill Bit: The drill bit is what does all the work when you are working on a project.

Most impact drivers come with a set of drill bits but most people buy specialized bits depending on what they plan on working on.

4. Brake: This is a part connected to the chuck.

The purpose of the brake is to keep the bit from revolving when it is not in use.

5. Trigger: The trigger is at the front and center of the tool and controls the on and off switch as well as the speed of the bit.

What Is An Impact?

The purpose of an impact is to transfer energy from one place to another by using a hammering motion. In an impact driver, the hammering motion is used to transfer energy from the drill bit to the material that you are working on.

The amount of energy transferred is controlled by how long you press down on the drill trigger. When you start to drill, the bit goes in and out quickly which produces smaller holes. When you press down harder, the bit moves into the material slowly and cuts more aggressively.

When Should You Use An Impact Driver?

Impact drivers are designed for heavy duty jobs and can break through the toughest materials. They are more expensive than regular power drills but their added versatility makes it worth the investment.

For instance, if you wanted to anchor a fence post into the ground then an impact driver is a must. It can also be used to install masonry anchors, wall anchors or any other type of anchor that requires a lot of force to make it stable.

Impact drivers are also excellent choices for people who need to bust up mounds of concrete or asphalt. If you have a patio or a pool and need to put in a drain then an impact driver can save you a lot of time and effort.

They can even be used to remove materials such as tile, stucco or wood. However, it is important to note that an impact driver should not be used for tightening screws or driving in finish nails.
