Rotary hammers can drill large holes and even bore into concrete. It’s also smoother to operate, drills faster, runs quieter and is a lot more powerful. But when you turn it one it works like a jackhammer that twists: The bit reciprocates (travels back and forth in a linear fashion), which “hammers” the bit into the concrete. Rotary HammerĪ rotary hammer works like a regular drill when the function is turned off. Hammer drills are generally more expensive than an equal quality standard drill because of the added function. But for larger projects, like drilling lag bolts, you’ll want a rotary hammer. For most residential concrete drilling, a hammer drill is the right tool. Like a wall anchor for hanging a picture or shelf. This vibration helps work the drill bit into the concrete.Ī hammer drill is great for drilling smaller holes into concrete. But when you turn it on the drill vibrates as it twists. It works just like a standard drill when the hammer function is turned off. Hammer DrillĪ hammer drill has two main functions. A standard drill or screw gun will work on concrete too but they need to have plenty of torque. They both do essentially the same thing but are different tools. The best drill for drilling into concrete is one of two tools: A hammer drill or a rotary hammer.

Let’s talk about each tool you’ll need in detail. A standard drill will work too but it has to have a certain amount of torque. All you need is a drill, a hammer drill or rotary hammer works best, and the right bit.

Since it’s being used more often, there’s more need to learn how to work with it.ĭrilling through concrete actually isn’t that hard if you have the right tools. And it’s being used more and more as a finish material for things like poured walls, interior floors and even countertops. Concrete is such a widely used building material in both residential and commercial construction that at some point your going to come in contact with it. If you’re a DIYer or a Pro, chances are at some point you’ll need to know how to drill into concrete.

If your bit gets red hot, use water to cool it down before trying to drill through the stone again.ĭrilling into concrete is an important skill to learn when building or remodeling a home because you’ll likely have to install concrete anchors at some point, which requires drilling a pilot hole. Trying to drill through a stone in one attempt can burn out your bit. If you hit a stone, you’ll know because the drill will stop penetrating, back the bit out periodically and let it cool.

If a crack forms, use a concrete crack filler to make repairs after the hole is finished. Trying to change angles once the bit has penetrated into the concrete can snap your bit or cause a crack. Keep lots of pressure on the bit and keep the drill at a steady angle.

Higher psi concrete has more stone, making it harder to drill into. However, if it hits a stone you’ll have a much tougher time drilling through and may burn out your bit. When drilling into a concrete slab, if the bit hits cement and sand, it will go through easily. Without a good bit, no matter what type of drill you use, you won’t drill through concrete. But a standard drill can do the job just fine. Hammer drills are really good because they have a vibrating feature that helps the bit get through concrete. Rotary hammers work best because they not only drill the bit into concrete, but also hammer it at the same time. Some plastic anchors require a solid backing, and will fall out if you drill through the other side.I’ve been a mason for over 25 years and can tell you firsthand that all you really need to drill into concrete is a good masonry bit and a power drill.

For hollow concrete blocks or thin concrete surfaces, check the fastener specifications.

X Research source You can reduce this length if you plan to remove the dust afterward (described below).

Add an additional ½' (6 mm) to the embedment to allow room for the dust that accumulates during drilling.

Heavier-duty projects require longer screws or concrete anchors, which should list the minimum embedment on the packaging.

Because concrete is a hard, dense material, screws embedded 1 inch (2.5 cm) deep are sufficient for hanging light-weight objects.

If you're not sure how deep to drill, follow these guidelines: X Research source If your machine does not have depth control, measure and mark the required depth on the drill bit with a pencil or masking tape.
