How To Use Hammer Drill? The Complete Step by Step Guide for 2022

A hammer drill is a power tool that is used to drive screws and drill into hard materials. It is a versatile tool that can be used in a variety of applications.
However, most people don’t know how to use this tool properly.

In this article, we will show you how to use a hammer drill to drill into concrete, wood, and metal. So, let’s break it down.

How to adjust the side handle?

Before using a hammer drill, you have to adjust the side handle. You have to rotate the shaft of the handle clockwise to loosen the handle. Then set it to the right position over the chuck and onto the drill body. Then tighten the handle rotating the shaft anticlockwise to place it securely.

To start drilling, hold the chuck with your left hand and use your right hand to rotate the handle. Keep your fingers close to the workpiece to avoid slipping. If you have a cordless drill, you can hold the battery and chuck in one hand and use the other hand to rotate the handle.

There are also different types of drill bits available on the market. You can choose one depending on the material you are drilling. For example, a hole for a screw will require a bit with a screwdriver bit shape. On the other hand, if you are drilling into masonry or concrete, you will need to use a bit with a hammerhead.

How to fit the depth stop rod?

You have to hold down the depth adjustment button and insert the depth stop rod to the required position.

To use a rotary hammer drill, you’ll need to position it in the correct position. The best way to do this is to hold the drill steady with one hand while you use the other to adjust the speed and torque. Once you have the drill in the correct position, tighten the chuck with your fingers.

How to insert and remove SDS bits?

To insert the bit first you have to wipe and clean the bit shank. Then you have to pull back the locking sleeve and then set the SDS bit.

And when you want to remove the SDS bit, you have to pull back the locking sleeve again and remove the bit.

NOTE:

If you want to prevent dust or debris from entering the drill holes, then you may use the supplied dust shield cap over the shaft of the

bits. But you have to do it before inserting bits into the SDS chuck.

How to change the chuck?

To change the chuck you have to pull the chuck collar back and hold it. Then remove the chuck and insert a new one. After inserting a new chuck, release the chuck collar.

NOTE: Before use, be sure whether the chuck is placed properly. If it is not, you may damage the drill bit, motor and/or gear box.

How to use the standard chuck? (Not hammer mode)

You have to rotate the chuck sleeve anticlockwise and open the chuck. Then you have to insert the drill bit in the jaws of the

chuck properly. After inserting the chuck, close the chuck by rotating the chuck sleeve clockwise.

NOTE: Be sure your tool is not in the hammer mode while using the standard chuck.

How to Properly Grease a Rotary Hammer?

Before inserting new bits in the rotary hammer drill, it will be better to grease them. Because, if you grease the bits before every inserting, then you can easily install and remove them. Besides, it will protect the chuck and help to last longer.

To grease the bits, you should take a small amount of oil or grease onto your fingers and rub it all over the drill bit. Then insert the bit into the chuck and secure it with the nut. Finally, turn the chuck to apply pressure to the bit and work the grease into all of its nooks and crannies.

To grease perfectly, you have to follow three factors.

  • Firstly, after cleaning the shaft, grease it. Because it will trap dirt and debris with the shaft so it will be easier to clean it.
  • Secondly, it will be better to use the recommended grease supplied by the manufacturer. Otherwise, if you use other substances, it may cause damage to your chuck.
  • Thirdly, you have to use enough grease, not more or not less. Too much grease may gunk up the chuck. So, you just need to rub it out.

How to use the Rotary hammer drill’s function or mode?

Most rotary hammer drills come with three modes or functions drill-only mode, hammer-only mode, and hammer/drill mode. You can change the function in accordance with your requirement.

In drill-only mode, the rotary hammer drill will just operate as a drill. In hammer-only mode, the rotary hammer drill will only work as a hammer. And in hammer/drill mode, the rotary hammer drill can function both as a hammer and a drill at the same time.

  • Drill Only Mode: If you want to use your rotary hammer drill for drilling into steel, wood, or widening holes then you have to select the “Drill only” mode.
  • Hammer Only Mode: If you want to chisel tile or remove mortar or burst small areas of concrete or hammer away surfaces then you have to use the “hammer only” mode. Basically, where the shaft doesn’t require rotation, you can select this “hammer only” mode and use the rotary hammer as a mini-jackhammer.
  • Hammer/Drill Mode: In fact, all the rotary hammer drills come with the “Hammer and Drill” mode as a default function and it’s the most useful function of the rotary hammer drill. If you want to drill into concrete, rock, packed clay, or masonry then you have to use this “Hammer and Drill” mode. It will allow you to use the rotary hammer as a drill and also have the ability to use it as a hammer at the same time.

How to Use a Rotary Hammer on Vertical Surfaces?

You can use your rotary hammer drill on vertical surfaces including walls, Posts, columns, etc. Follow the below steps to use your rotary hammer on the vertical surfaces:

  • First, ensure your safety you have to put on safety gear, wear safety glasses as well as wear a pair of gloves. And you have to be over sure that your hammer cord (if it’s corded) is securely out of the way.
  • Then, you have to insert the drill bit into your rotary hammer. But before installing, grease the bit shank perfectly and pull the chuck back to insert the bit. After inserting the bit, release the chuck and make sure the bit is placed properly.
  • Select the mode you want to use like you can select “hammer and drill” mode for drilling holes, and you can select the hammer only mode for using scaling tools and chisels.
  • Hold the rotary hammer securely with both hands and be sure that your footing is stable. For working on every vertical surface, you have to be sure that you’re away from a comfortable distance from the target venue and that your position is stable.
  • To start drilling, hold the tool against the vertical surface like a wall or column, and ON the trigger. You have to hold the bit at the same place till it digs completely. But note that, you shouldn’t apply too much force on the tool. Your duty is just to hold the tool in the right position straight.

When you’re done drilling, simply release the trigger and the bit will come out. If you’re using a corded hammer drill, make sure to unplug it from the power source when not in use.

How to Use a Rotary Hammer on Horizontal Surfaces?

It’s much easier to use your rotary tool on horizontal surfaces including ground or floors compared to use on vertical surfaces. Because you don’t need to hold the tool against the vertical wall or column. But here also you have to hold the tool straight securely.

However, here are the steps on how you can use your rotary hammer on horizontal surfaces:

  • Insert the drill bit or install the necessary tool accessories. If you want to put in small anchors, then it will be better to use quite a smaller SDS or SDS Plus bit. On the contrary, if you would like to put in lag bolts, you have to use longer 16-inch bits. Grease the bit shank before inserting properly.
  • Wear your safety gear including eye protection, hand gloves, etc. Though rotary hammer drill is comparatively a safe tool as it uses low RPMs, it will be wise to use at least eye protection.
  • Select the mode “Hammer Only” for chipping and digging or “Drill and Hammer” mode for drilling holes.
  • Aim the tool at the object point and hold it securely using both hands. Then, press the trigger to let the tool work and you just hold it in the right position until it finishes its drilling.
  • After use, let the tool cool down and then release the bit and clean it properly. If it’s corded, then unplug it from the power source and keep it in the right place.

How do you maintain your rotary hammer?

If you want to let your rotary hammer drill work efficiently and last longer then you have to keep it under regular maintenance. Here are a few important suggestions that will help you to maintain your rotary hammer:

  1. Don’t apply too much force while drilling and let it perform its work freely.
  2. Select the right size and the right type of bit in accordance with the material you’re drilling.
  3. Clean off the bit perfectly so that any dirt or debris is not hidden at the end of the bit.
  4. You have to grease the bit shank before every time you insert the new bit.
  5. Try to use the manufacturer-recommended grease.
  6. Know about your tool’s LED signal that alerts you.
  7. Before using your rotary hammer, read the manual instructions book thoroughly that it comes.

Can you use an impact drill for concrete?

Impact drills are not typically used for drilling in concrete, because the high-speed rotation can damage the drill bit. Use a hammer drill instead.

If you need to drill in concrete, you’ll need to use a rotary hammer drill instead.

How to use a hammer drill for concrete?

The best hammer drill will finish a 2-inch deep hole in concrete in less than a minute. Drill bit size can be determined by how deep you need to go and the diameter of the hole that you want to make. A drill bit with a smaller diameter will go into the hole faster, but it may not be able to penetrate all the way through. A drill bit with a larger diameter will take longer to go through the concrete, but it is more likely to penetrate all the way through.

Here I’m sharing how to use a hammer drill for concrete.

1. Pre-heat the hammer drill bit.

2. Drive the bit into the concrete until it touches the bottom of the hole you want to make.

3. Use your hands to hold onto the bit and twist it around until you have drilled a hole large enough for your tool to fit through.

4. Remove the bit from the concrete and use a wrench to tighten or loosen the screws on the drill Bit.

5. Use the wrench to tighten or loosen the screws on the drill bit until it is tight enough so that it does not spin when you hold onto it.

6. Repeat steps 2-5 until you have drilled all of the holes you need.

How to drill into the brick with a regular drill?

Drilling into brick cannot be done with a normal drill. A special bit called a drill bit for brick needs to be used. This bit has a smaller diameter so it will go into the brick easily, but it will not damage the brick.

Brick drilling is a common task that needs to be done by homeowners and professionals alike. To drill into brick, you will need a regular drill, bit size specific to the type of brick you are drilling into, and a hammer.

To begin, preheat the bit on your drill before inserting it into the hole. Once it is hot, insert the bit into the hole and begin turning it around. Remember to hold onto the hammer so that you can hit the drill with it in order to break through any stubborn bricks or mortar. Once the hole is large enough, use the wrench to tighten the screws on the drill bit and then remove it from the brick.
