How to Drill and Anchor into Concrete

In this article we’ll cover how to drill through concrete, brick, and cement and also how to mount, fix, or attach something to the wall or floor using your anchors.

The first thing we’re going to need is a drill driver with a hammer function. If you see a little hammer symbol on your drill it means that it will allow you to drill through brick, concrete and cement.

However, if the surface you’re drilling through is too hard, then the drill driver will struggle, so in that case you’ll need to use a rotary hammer drill. A high quality rotary hammer drill goes through basically anything, but if there are soft materials such as sand, cement or even a mortar between your bricks, a hammer drill will go through with no problems.

Regardless which drill you decide to go with, you’re going to need to use some masonry bits. The easiest way to know if you’ve got a masonry bit is to we have a look at the tip and check if it looks like a shovel head. That’s a very good indicator that it’s a masonry bit, and you’re going to need a masonry bit to get through brick, concrete or cement, otherwise you’re just damaging your drill bit and you won’t be able to go through.

When it comes to mounting or fixing something to the wall or floor, there are four types of anchors commonly used.

For light fixing, meaning anything up to about thirty kilos or sixty pounds, depending on the gauge that you’ve bought and the thickness of the material, you can use standard wall plugs.

Standard wall plugs come with an outer screw, so you basically drill your hole, tap the standard wall plug straight into that hole and then you get any heavy-duty screw and you can put that into the back and anchor or mount whatever it is you’re after straight into the wall.

There are standard wall plugs that come with a special screw that’s designed to not only bite on as a regular screw but also hold into position with the help of some threads and ridges that prevent pulling.

Both variations have Phillips heads on their back and are very easy to install.

When it comes to heavy-duty fixing, so something that’s really solid and really heavy, you’ll want to use a Dynabolt or a Ramset AnkaScrew.

A Dynabolt has been the number one choice for most people simply because it works so well and it’s very effective. Drill a hole, push the Dynabolt into place. and then you can tighten the nut on the back. As you tighten that nut, the sleeve that’s on top starts to expand and that actually lodges everything into position in that hole.

One of the biggest downsides of Dynabolts is that once they’re expanded, you’re actually not able to pull them out, they are not reusable.

A recent innovation on the market, just 3-4 years old, is the Ramset AnkaScrew, but other brands do make it as well. It’s basically the anchor and the screw all-in-one. With a Ramset Ankascrew, you’re able to just drill a hole, put the screw into place, screw it in and once you’re done with it you can actually reverse that out and just fill that hole up.

So now that you have your tools ready and your masonry bits on hand, it’s time to start the actual process of drilling into concrete.

How to drill into concrete with a hammer drill (for light fixing)

-Pick a location where you’re going to be drilling into

-Put your hammer drill into hammer mode.

-Drill a hole into the brick. If the material is soft, it should go easy and effortlessly, but if it starts to struggle and you can’t push through, you may need to switch to a rotary hammer drill.

-Pop a standard wall plug into the recently created hole and tap it flush with a hammer

-Get your screw and attach it to the end.

How to drill into concrete with a rotary hammer drill (for heavy fixing)

For heavy fixing we’re going to be using the rotary hammer drill.

– Pick your location where you’re going to be drilling into

– Put your rotary drill into hammer and drill mode

– Drill a hole into the concrete.

– Pop a Dynabolt into position and use a hammer to tap it in. Make sure the nut is already on and not over threaded before you tap it in.

– Once that’s done, use an adjustable wrench or a socket set and tighten that up.
