Mounting items on concrete walls means boring holes to place the mounting brackets. The impact you need to get a whole through depends on several factors other than a hammer drill brand.
A hammer drill is an excellent choice for a mason who wants to drill holes on concrete walls. The pounding force of the hammer is what makes it desirable for blasting through masonry. During the spinning of the hammer drill, the bit will chisel away from the concrete creating a mechanical process that produces the pounding action to separate the two tools to make that “hammering effect.” Check out this blog post (to know more about rotary hammer drill for concrete).
What is Inside a Hammer Drill?
Two discs exist inside a hammer drill with ridges enabling one disc to slide past the other. The rising and falling action causes the chuck to slam back and forth. When the hammer drill has no force between them, a clutch separates the two disks stopping the pounding action. The hammer disks’ slow down the wearing out of the drill when you use it’s pounding hammer action.
Hammer Drill Bits
Due to the light masonry work, the drill mainline is for boring holes in bricks, concrete, and mortar. Occasionally you can use it to drill concrete rebar. You only need to spend money on a bit that will serve your project successfully. The more you spend on a hammer bit, the better protection you get in terms of the carbide tips. Such tips attach securely and easy on the drill shank hence reducing the possibility of breakage.
Power Consumption of a Hammer Drill on Concrete
Getting the right power consumption of a hammer drill requires looking into the tool usage, type or a drill, model, brands, etc.
Type of Drill: Corded or the Cordless
You can get a hammer drill either packed with lithium-ion batteries as a source of power or get a corded one that gets its supply from the mains. A corded hammer drill is more powerful than the cordless on that depends on battery power to function. Corded hammer drill offers a constant source of power than the corded ones. When serving a long day, plug the cord into the socket, and your work continues.
A battery-powered hammer drill will likely run out of power after several hours of working. Their power consumption is limited, they are handy for DIYers who like portability, versatility, and convenience when moving around the working space.
Motor Speed
Different tasks require a drill to run at speeds appropriate at that particular moment. You will need to improve the drill bit’s accuracy penetration, thus regulating the power consumption with every task. You can get either a hammer drill with variable speeds or one that allows for speed adjustments.
When you push a drill into an object at a lower speed and leave it constant, that drill will consume more power than an exercise that responds to the kind of resistance it receives.
Mode of Drilling
The mode introduces a pulsating action that drives the bit through masonry surfaces like concrete. When drilling, the pulsating effect does not stop, which means you are using more power than a regular drill.
Using the hammer drill in drive mode eliminates the pulsating hammer effect and engages the torque setting for precision. To switch to the drive mode, look for a screw symbol on the mode control switch.
Other Considerations
Getting the same amps, a hammer drill needs concrete work depends on many factors, as already evident. High-end hammer drills may have more features that may require more power to run. Having a flexible handle is one such feature.
Final word
Hammer drills are not as standard as the power drills in a workshop setting. Most DIYers prefer the hammer drills because of their convenience and efficiency in handling routine tasks such as drilling holes and driving screws into concrete, wood, metal, bricks, and other hard surfaces. Some prefer it for their low rating of power since most run on battery packs that need recharging. Whether you choose a corded or a cordless hammer drill, what counts is its convenience to you.
