The wattage is one of the most critical features to consider whether you’re using a corded or cordless drill. It has a direct impact on the power utilization, affecting how strong it is and how much electricity it consumes from your home.
The average cordless drill requires 25 to 100 watts to charge, whereas most corded drills require 800 to 1,200 watts to run. The fact that corded drills demand a continuous current explains why they require so much more.

What is the average amount of electricity used by a power tool?
Power tools are voracious eaters. They eat up more than their fair share of electricity the instant you switch them on. As a result, while feeding your power equipment, you’ve undoubtedly tripped a few circuit breakers in your shop. It’s probably a good idea to check at wiring to make sure you have enough electricity for your power equipment.
How much power do my tools need?
Amps are used to power tools. Check the nameplate on the tool’s body or motor housing to see how much they require. Look for AMPS and VOLTS information. Make a list of how many amps each tool uses. Make a note of any tools that can be connected to run on 240 volts rather than 120 volts.
Small power tools (sanders, jigsaws, etc.) often need 2 to 8 amps. 6 to 16 amps is usual for bigger power tools (router, circular saw, tablesaw, lathe, etc.). Duct collectors and air compressors, for example, may require much more electricity.
Do I have enough power to draw from?
100- to 200-amp service is standard in most homes built in the previous 40 years or so. This should be plenty to power a modern home and a store. Consider having a subpanel installed in your shop so that you don’t have to share circuits with your home. This allows for shorter wiring, which reduces power loss and heat buildup, as well as the ability to turn off the shop’s electricity when it’s not in use.
You probably only get 60-amp service if your house was built before 1950 and you haven’t made any electrical upgrades. To avoid tripping breakers when using power tools, you should have your service doubled and a new panel installed.
How should I size my circuits?
Begin by looking at the list of amperage needs you made for your tools. Keep in mind that electrical rules dictate that a circuit’s load should not exceed 80% of its capacity. This means you’ll need a 20-amp circuit to run a 16-amp tablesaw. When using two high-power tools at the same time, such as a tablesaw and a dust collector, two different circuits are required to handle the load.
Should I rewire to 240 volts?
The use of amperage is cut in half when the voltage is doubled from 120 to 240 volts. This means you can operate a 14-amp tablesaw and a 12-amp dust collection at 13 amps instead of 26 amps, allowing you to use the same 20-amp, 240-volt circuit to power both machines. Of course, don’t forget about non-tool objects in your business, such as lights and heaters, when straining your power limits.
Contrary to popular misconception, using 240 volts instead of 120 volts does not make a power tool more powerful because the amp use is decreased in half while the wattage remains the same. A 16-amp power tool on a 120-volt circuit, for example, consumes 1,920 watts (16×120=1,920). On a 240-volt circuit, the same tool now runs at 8 amps and consumes 1,920 watts (8×240=1,920).
If you were using an 18-amp tool on a 20-amp circuit, you might notice a power differential. Switching to 240 volts reduces the load to 9 amps out of a total of 20, ensuring that the motor continues to run at full power.

What is the wattage of a DeWalt drill?
So we’re dealing with four different types of data. 560, Max Speed, Max Torque, Unit Watts Out (the Constant, often shown as K). Here’s how the equation appears when there’s nothing in it. Constant changes require torque in in-lbs, and I’m not digging up another one.
Max Watts Out = Speed (RPM) x Torque (inch-pounds) / 560 (estimated)
To make this work, remember that if you use the peak torque value, you must also use the maximum RPM in the same setting. This is the highest number in the lower range of a multiple-speed drill.
Quick Case Study
Let’s take a look at the DeWalt DCD790D2 Brushless Compact Drill, which is one of DeWalt’s drills. In high torque mode, it has a Unit Watts Out rating of 360 and a maximum speed of 600 RPM. We get the following results from our Unit Watts Out vs Torque calculation:
360 UWO = 600 RPM x Torque (inch pounds) / 560
After solving this equation, the maximum torque of this 20V small drill is 336 in-lbs.
What is the minimum power requirement for a drill?
Light-duty cordless screwdrivers with voltage ratings of 4 to 8 volts are sufficient, and drills with voltage ratings of 12 to 18 volts will meet most householders’ labor demands. A high-power model can handle more work, but it also requires a larger, heavier battery. A cordless drill battery must be recharged on a regular basis.
Is it true that power drills consume a lot of electricity?
A more efficient, rechargeable Lithium-ion battery now powers cordless drills. This technology allows the battery to charge faster (typically in under 60 minutes) and to hold more charge for longer. Furthermore, the same battery can be used with other power tools from the same manufacturer. Assisting in the cost-cutting of large-scale battery purchases.
Watts are the unit of measurement for corded power drills. Typical hammer drill power ranges from 450 watts for basic machines to over 1500 watts for more powerful versions. For drilling masonry, a higher wattage is preferable. While drilling into plasterboard requires a lower wattage, a lesser wattage will suffice. A 550 watt drill is sufficient for most basic home DIY projects.
The power of a cordless drill is measured in volts. The more powerful the drill, the higher the voltage rating. The voltage of a battery normally ranges from 12 to 20 volts.

What is the power output of a hammer drill?
You should consider the technical aspects as you would with any power tool. This way, you’ll be able to figure out which hammer drill is perfect for you. Which parameters are the most crucial?
Hammer drill wattage
The wattage of a hammer drill is the most crucial factor to consider. The larger the hole you can drill with a higher wattage, the better. Drills with a power range of 400-650 watts should be able to drill holes ranging from 6 to 15mm in diameter. Choose a hammer drill with more than 800 watts if you plan to utilize a hole cutter.
The maximum diameter with a hammer drill
The largest hole diameter that a certain model can make is frequently provided by manufacturers. You should not, however, take this as an exact indication. If you need a hammer drill to drill holes with a diameter of 10 mm, you should avoid selecting a drill with a maximum drilling size of this size. To be safe, use a drill with a drilling diameter of up to 15 mm, for example.
Type of drill chuck
Different drill chucks are available for different drill models. Key chucks are the most common type. To tighten and loosen them, a unique key is required, as the name implies. Key chucks offer a tighter hold on the bits, but they take longer to change. Furthermore, if you lose the key, you will be unable to use the drill. With keyless self-locking chucks, this is not the case.
Hammer drill adjustment range
Two-speed hammer drills with more than 600 watts are common. This allows you to control the rotational speed. More complex drills provide a larger range of speed adjustment, and some even allow you to specify a precise impact rate. If you want to use your drill on a variety of materials, these features will come in helpful.
What is the current draw of a cordless drill?
Let’s return to the pipe analogy to calculate out how many amps your cordless drill consumes.
As a result, a 20v cordless drill will always draw more amps than an 18v drill. You’ll also need a battery that’s rated for your drill’s voltage.
Because the amperage draw varies depending on the wattage of the drill’s motor and the voltage of the drill’s battery, you’ll need to do a quick calculation to figure out what your drill’s amperage draw is.
How to Calculate Amperage Draw
Divide the total number of volts on the battery by the watts of your cordless drill’s motor. This will reveal the drill’s amperage draw.
An 18v cordless drill with a 250-watt motor, for example, will use around 14 amps.
It’s important to keep in mind that a 3Ah battery will draw 1 amp for 3 hours. So, if you’re using 6 amps, you’ll need to recharge after around 30 minutes. To see how the current draw influences run time, look at the table below.
It, now that you know how to find out how many amps a cordless drill uses, you can do so for virtually any drill. It may assist you in determining which battery to purchase or if you want an 18v cordless drill or a 20v cordless drill.
It all boils down to what’s most important to you. You’ll want to choose a lower voltage and a higher Amp Hour rating if you want your drill to last longer on a charge.
If power is more vital to you, consider a drill with a greater voltage and Amp Hour rating.
