What concrete means?
Heavy, substantial building material is produced by combining a cementing material (such as Portland cement) and a mineral aggregate (such as sand and gravel) with ample water to allow the adhesive to settle and bind the whole mass.
Editor’s choice: Bosch HC5091 Hammer Bit
- Carbide tipped bit head is harder, tougher, and more resistant to extreme loads.
- 1-1/2″ diameter, 16″ useable length, 23″ overall length.
- Four chiseling faces and cutting edges double the chiseling action for more efficient drilling.
- Shank Diameter :0.0; Useable Length :16 inches.
Do you need a special drill to drill into concrete?
With a regular drill, you can drill holes in concrete. A lot of people think you can’t drill concrete on a standard drill. They think you need a special hammer drill with hardened drill bits. Because those tools make the job easier, they’re not required.
Editor’s choice: Bosch 11316EVS SDS-Max Demolition Hammer
- Lighter Tool, Heavier Performance.
- Adjustable Positioning.
- Reliable Performance.
- Automatic bit locking and maximum impact energy transfer rate.
What kind of drill should I use for concrete?
Drilling into concrete is challenging if the concrete is thick, heavy, and has built-in aggregate stones that may be difficult to the drill bit. Using dull bits drilling could be easy. When the bit hits the aggregate, it drags the bit even further. A hammer drill is an excellent solution for drilling into concrete.
Editor’s choice: Milwaukee Cordless Rotary Hammer, SDS Plus
- Cordless Rotary Hammer Drill.
- Voltage 18.0, Chuck Type SDS Plus.
- 0 to 4900 Blows per Minute, 0 to 1400 No Load RPM.
- 1 In. Capacity in Concrete, 1 In. Solid Bit Capacity, 2-1/2 In. Core Bit Capacity, Impact Energy 1.7 ft.-lb.
Why do you need a hammer drill for concrete?
Like a drill/driver, a hammer-drill can drill holes and drive screws. It is specially developed to perform another task: drilling holes through concrete, brick, stone, and other masonry materials with incredible flexibility and quality.
Whenever adequately adjusted, a hammer drill may very well bore a hole. If the project needs masonry drilling, you will need a hammer function. Builders and technicians typically use hammer drills to mount electrical boxes and block wall fixtures.
It might be a smart move to rent a hammer drill if you need it once in a while because that tool is too much expensive. Cordless models can start at around $70 with essential functions and power and without masonry bits. On the other hand, renting one will cost you approximately $40 for a one-day job.
How long does it take to drill a hole in concrete?
Several variables affect this. For example, the stone’s size and hardness used in the concrete floor-usually the granite stones will be crushed between 1/2″ and 1″ in diameter. What kind of hardness the floor was cast to-I’m afraid a metric, so we calculate in MPa-it will be a lot easier in a 15MPa than a 40MPa Slab. If there is some steel re-enforcement-if so, I would highly recommend that you get something to search for this similar to a metal detector-it would save you a great deal of time if you attempt to drill through steel rebar (not to mention, you might be losing the structural integrity of the slab).

The bit itself has a lot of impact from the drill’s side. But even the RPMs and the frequency of the hammer action hits. E.g., Yes. I saw a Bosch commercial drill take an hour to run on a hole at 4000 RPM. The Hilti industrial barely looked at the concrete at 700 RPM and made holes under 10 seconds in the same concrete. Faster isn’t necessarily “faster” when it comes to concrete, don’t be afraid to set your drill to turn slower-sometimes it just reaches the sweet spot. You end up getting through the concrete a lot faster.
If you read the manual, you will probably see a chart explaining the most suitable settings for your drill + bit + medium. Stick which, they’ve been checked for you.
Also: “Don’t push!” Adding additional pressure won’t make it drill faster. It’s going to be slower. The bits get worn out more quickly, they could even split, and all you’re going to do is produce extra sweat on your forehead. Only hold enough pressure to prevent the drill from bouncing around, nothing more.
The Best Way to Drill Into Concrete
Whether it’s a wimpy tiny hole up to (say) 25mm diameter, I’d use a rotary hammer drill for day-to-day business. Rand drill for deep holes several meters deep and (say) 65mm dia.
If I want a beautifully smooth hole to use the so-called chemical anchors, I will use a diamond core drill. These are suitable for up to (say) a meter or two in diameter.
Other choices include diamond wire saws, road saws, or thermal lances (if you drag your knuckles on the ground when you walk).
No matter what I do, I would never mess with a handyman “hammer-drill.” They’re spectacularly loud, shouting when they go, finding it so hard to do a lot of tasks, and going thru drill bits at a rate that’s breathing. Affordable rotary hammer drills are commonly available in semi-respectable hardware stores these days. They can bring joy back to the life of those doing “boring work.”
