Drilling in concrete like a pro

If you are to drill into a concrete wall, you will need the right drill. Different concrete types need a varying hardness level. Screwing into the concrete will need a drill, preferably, a hammer drill that has a tungsten carbide bit.

If you are drilling into the decorative concrete such as internal walls which are usually softer, you can do so using a masonry drill bit or a rotary hand drill. Ensure that you take everything slowly.  Make sure you don’t burn the motor and cause damage to the drill bit.

Tips for drilling into concrete

Before breaking out your drill and drill bit, you will need to check these concrete drilling tips:

  • Pick the right drill bit. You will want to invest in the right masonry bits
  • Choose the right tools. If you are serious about drilling into concrete, you will want to use a hammer drill. This is a good choice as it uses a fast hammer action for driving the drill bit through a mate.
  • Use the right pressure. While drilling in concrete is a bit hard, using more pressure isn’t the solution. This may end up damaging the motor of the drill
  • Use water. It’s advisable to wet concrete when drilling to reduce the dust and also prevent overheating
  • Be ready for jamming. When drilling concrete, you will face various materials that aren’t concrete such as aggregate rocks and rebars. When this happens, you should remove the bit and drill, and break down the materials using a nail and hammer. You can also consider drilling in another area
  • Protect yourself. Ensure that you are wearing the right protective appliances.

How to drill in concrete using a hammer drill

There are several steps you need to follow when drilling in concrete. These are:

Mark the spot

You should start by marking the surface where you will be drilling a hole. You will want to think of how deep the hole should be. You can measure this using a stop bar. Alternatively, you can determine the depth by wrapping masking tape around the drill bit.

Make the drill ready

Wear your goggles. You should then put the right size of tungsten carbide masonry drill bit into your hammer drill. Ensure that this is well locked to prevent slipping when drilling.

Get in the right position

Hold the drill with the feet apart by shoulder width.  To get greater control, you can use the auxiliary handle. If there is no handle, you should hold the hammer drill in a similar way to the handgun. When learning to drill a hole, ensure that the tungsten carbide drill bit remains perpendicular to concrete. The hammer action will produce some kickback.

Drill the guide hole

When the drill is on a slower setting, create the guide hole. If the hammer drill has only one speed, you can operate it in short burst until the guide hole is about ¼ inch deep.

Drill your desired hole

Hold the drill firmly but lightly. This will enable you to handle any stone pockets or hard material in the concrete. It’s easy to lose control of the drill when you are drilling via concrete.  With the guide hole in place, you can easily control the drill. Even as you continue to gain confidence, you can now increase the speed of the hammer drill until you have created the hole.

Overcoming obstruction

When you face an obstruction, you may think that forcing a drill through will work. However, this will only serve to damage the drill and interfere with the hole. You should instead eject the drill and work on the hard spot using a nail and a hammer. Provide the hammer with a few sharp taps. Avoid whacking it as you may lose control of the nail and divert the hole.

You can now chuck out the nail and continue drilling at a low speed until you overcome the blockage.

Clear debris

Ensure that after about 20 seconds, you remove the drill bit to get rid of debris in the hole. This will enable the drill bit to continue working on the hard concrete, without putting the extra effort into grinding the concrete dust.

Anchor attachment

After you have drilled the hole to your preferred depth as shown in the top bar, or even the masking tape of your drill bit, it’s time to chuck out the drill. You can take the compressed air to remove dust from the hole. Make sure that your safety goggles are still on so that you can continue protecting your eyes.

Ensure that you have a vacuum cleaner to remove any falling mess. You can then put the anchors into a hole, tapping them flush using a hammer. You can then repeat the whole procedure to continue making more holes.

Wrapping up

With the best rotary hammer drill, it should be very easy to drill through concrete. While you shouldn’t expect it to be similar to drilling into butter, you can save yourself a lot of frustration by using the masonry bit and hammer drill.

When you learn how to drill into concrete, you will never struggle again about hanging images in concrete walls or attaching a concrete countertop on another surface. While concrete drilling isn’t a straightforward process, understanding how to do it well will pay off in the future.  Use the above tips for all your concrete drilling.
