How Does A Hammer Drill Work?

A hammer drill is a drill bit attachment used to create small holes in various materials. The drill bit is mounted on the end of a handle and struck with a hammer to create the desired hole.

Hammer drills are common in construction and DIY contexts, as they are versatile and easy to use. Professional experience is important when trying to use a drill. You’ll have to brace your device with your hands.

The technique, usage, and troubleshooting for a hammer drill are different compared to impact drivers. A common procedure for troubleshooting a hammer drill is similar to impact drivers.

This article will cover the following :How does the hammer drill work? How do you use the hammer drill? What to do if the hammer drill doesn’t work?

So, let’s get started without wasting any time.

How Does A Hammer Drill Work

What is a Hammer Drill?

Hammer drill, also known as impact drill or percussion drill, is a type of rotary drill with a hammering mechanism .It is basically a power tool primarily for drilling in hard materials.

The tool’s impact mechanism can be switched from an energetic mode into a low-vibration dormant state. Once it goes into the dormant state, it can perform tasks such as screw driving.

How Does A Hammer Drill Work: Mechanism

Hammer drills are equipped with a cam-action or percussion mechanism that a toothed gear of this type seizes and presses on the bit.

Cam-action is a special kind of action in which they procedurally move the entire drill and bit relative to the drill’s axis of rotation.

This type of drill is typically used with or without the hammer motion, but it is not possible to use the action alone due to its rotation over the cams that makes the hammer motion.

A hammer drill has a clutch that allows it to not only incise the drill bit, but also pulverize it.

The actual length of a path the bit travels and the force of its blows, both are very small, and the hammering action is extremely quick.

They can be thousands of “BPM” (blows per minute) or “IPM” (impacts per minute).

Although each blow is of relatively low force, these thousands of blows per minute are sufficient to break concrete or brick, using the masonry bit’s carbide wedge to pulverize it for the spiral flutes to remove it.

As a result, a hammer drill drills much faster than a regular drill through concrete or brick.

Hammer drills are becoming increasingly powered by cordless technology.

Using A Hammer Drill

Similar to a drill, a hammer drill uses two different motions to punch through hard materials. One motion is like that of a regular drill in that it spins down into the material to create a hole.

Another one is, It mimics the motion of a hammer or a chisel as it moves up and down to pulverize brick and concrete.

If you will be putting to use your hammer drill, you should make sure you have the following:

  • Pencil
  • Safety Goggles
  • Compressed Air
  • Hammer Drill
  • Drill Bits.

Step-1) Mark your Surface

Your first step is to mark which wall or surface you would like to drill using a pencil and ruler. Then comes

Step-2) Adjusting your Drill Bit

Protect your eyes from dust when using a drill and prevent dust from entering the eyes by wearing safety goggles.

Before you begin drilling a larger hole, you should first drill a smaller hole in the location. After that,

Step-3) Adjusting the Depth

Nevertheless, be sure to set the depth stop if you possess a hammer drill with a depth limiter. If not, you can use a piece of masking tape to mark the depth stop on your drill. Then,

Step-4) Start Drilling

Start your drilling operation with a lowly speed and energy and gradually ramp them up. As you advance, increase the speed and power to your utmost. Finally,

Step-4) Cleaning the Hole

Maintain drilling bit by bit to eliminate dirt after every 15 seconds when you hole is drilled. Once you have completed these chores, you can blow compressed air into the hole in order to get rid of all the residue.

What Does A Hammer Drill Do?

Hammer drills are usually not used for production construction drilling but instead for occasional drilling of holes in concrete, masonry, or stone.

It is also used to drill holes in concrete to place a wall frame.

Hammer drills often have a lever or switch that locks off your special “hammer clutch,” turning it into a standard drill for wood or metal work.

Hammer drills are more costly and more bulkier than regular drills, but are desirable for applications where the material to be drilled is unknown to be composed of wood or concrete blocks.

It is also used to remove material from a hole, maintaining the hole’s depth.

Troubleshooting: What to Do if the Hammer Drill Doesn’t Work?

However, there are some common problems to troubleshoot for hammer drills that can help prevent potential issues. Let’s check it out.

If the hammer drill doesn’t turn on

The hammer drill will not turn on if one of the motor brushes is damaged.

First check the brushes, and then check the battery charging switch, power cord, holder, and armature in case one of them has a damaged hammer drill.

If you notice the issue, you can fix it. Otherwise, take the drill to the service center for warranty service.

If the hammer drill mode is too slow

If the hammer drill mode is too slow due to a motor or internal failure, the fault may be caused by a carbon brush, defective bearings, faulty armature or gears, and then play rings, pistons, transmission gears, and inner parts.

You can resolve the issue by having a service person inspect it or by referring to the user manual.

If the hammer drill gets too rusty

Clean dust and debris from the charger and ventilation region. Wash and put away the vent cover without oil or any grease.

An innocuous soap and a dry cloth are the best way to wipe down the tool handle.

Do not use gasoline, solvent, turpentine, lacquer thinner, paint thinner, chlorine-based cleansing solutions, ammonia, or ammonia-based house cleaning products.


What does BPM(Blows per minute) mean?

The blowing speed is known as blows per minute (BPM). That means how much blowing action occurs per minute. When the bpm is high, the blowing action is high. It can drill effectively.

Is hammer drill a good choice for concrete?

A hammer drill is ideal for light masonry. She has worked best in drilling holes in bricks, mortar, and concrete blocks, but it may also deal with the occasional hole in concrete.

Final Words

So, finally you made it. All of your concerns must be cleared now, as you have gone through all of the writing.

Using a hammer drill needs more experience and knowledge. Professionals, DIY enthusiasts often use these tools and face some common problems. That is what we covered in our troubleshooting section.
