What Do Numbers Mean on a Cordless Drill?

When shopping for a cordless drill, you may come across numbers that seem to have no meaning. What do they mean?

A good rule of thumb is that if you are using your drill for light tasks, such as drilling small holes in wood or plastic, then a lower voltage should suffice. On the other hand, if you plan on doing heavier-duty work like driving screws into the concrete, then opt for something with a higher voltage, such as 18-24 volts, so that it can handle the job without overworking itself and potentially damaging its motor or battery pack.

The next number listed on your cordless drill is usually its speed rating, measured in RPM (revolutions per minute). This tells us how fast the bit spins when we pull the trigger and ranges from 0-2000+ RPM depending on what type of task we are performing; lighter tasks, such as drilling holes in softwood, will require less speed, while tougher jobs like driving screws into hardwoods need faster speeds to get through them efficiently without burning out our motor prematurely due to excessive strain placed upon it by slower speeds. It’s important to note here that some drills offer variable speeds, which allow us to adjust this setting according to whatever task we’re working on – these models tend to be more expensive but offer greater versatility than their single-speed counterparts, so consider investing in one if possible.

Voltage: The Power Behind Your Drill

Voltage is one of the most important factors to consider when buying a drill. It determines how powerful your drill will be and what type of tasks it can handle. The higher the voltage, the more power your drill has, so it’s essential to get the right amount for whatever job you need done.

The voltage of your drill directly affects its performance level and capabilities; higher voltage means more torque (power), while lower voltage produces less torque but uses less electricity overall. For example, if you are looking for a powerful cordless drill, then you should opt for something with at least 18 volts or higher – this will provide enough juice to tackle tougher jobs such as drilling into concrete or masonry walls without running out of battery life too quickly.

Speed: How Fast Can You Go?

When it comes to drills, speed is a key factor in performance. The faster the drill, the more power and torque you can generate when drilling into hard materials like concrete or brick. But how fast should your drill be?

The first thing to consider is what type of material you’ll be drilling into most often. For soft woods and plastics, a slower speed will work just fine. However, if you’re going to be drilling through harder materials such as metal or masonry, then a higher speed setting is recommended for optimal results.

Another important factor to consider when selecting a drill with regard to speed is its variable-speed control feature. This allows you to adjust the rotational speed of your drill depending on the task at hand – from slow speeds for precision work all the way up to high speeds for heavy-duty applications such as demolition jobs or driving large screws into dense wood surfaces quickly and efficiently.

Finally, make sure that your chosen model has enough power behind it, too – otherwise, even if it has an impressive top-end speed rating, this won’t translate into better performance due to the lack of torque generated by lower-powered motors.

Torque: Get Ready to Twist and Turn

When it comes to cordless drills, torque is a key factor in determining the performance of your tool. Torque measures the amount of rotational force that can be applied to an object, such as a screw or bolt. It’s measured in Newton meters (Nm) and typically ranges from 0.5 Nm up to 70 Nm for professional-grade tools.

The higher the torque rating on your drill, the more powerful it will be when driving screws into hard materials like wood or metal. This makes them ideal for heavy-duty tasks like drilling through thick walls or assembling furniture with large bolts and screws. Lower torque ratings are suitable for lighter jobs such as hanging pictures or building small projects out of thin materials like plywood and plastic.

FAQs in Relation to What Do Numbers Mean on a Cordless Drill

What do the different numbers on a drill mean?

The numbers on a drill refer to the size of the drill bit, usually measured in millimetres or inches. The most common sizes are 1/16”, 3/32”, 1/8”, 5/32” and 3/16”. These measurements indicate the diameter of the hole that can be drilled with each bit. Larger bits will create larger holes, while smaller bits will create smaller holes. It is important to choose the right size for your project, as using an incorrect size could cause damage to materials or tools. Additionally, some drills come with adjustable settings, which allow you to change the size of the hole being drilled without having to switch out drill bits.

What is the 1 or 2 on the top of my drill?

The top two features of a drill are its power and torque. Power is the amount of energy it can produce, measured in watts or amps. Torque is the measure of how much force it can exert when drilling into materials, usually measured in Newton meters (Nm). Generally speaking, drills with higher power and torque ratings will be able to handle tougher jobs than those with lower ratings. When shopping for a drill, make sure to check both these specs, so you get one that meets your needs.

What are the 1 and 2 settings on a drill?

The first setting on a drill is the forward or clockwise rotation, which is used for drilling into materials such as wood and metal. This setting should be used when you need to drive screws in straight and fasten them securely.

The second setting on a drill is reverse or counterclockwise rotation, which is used for unscrewing screws or removing stuck bits from materials like wood and metal. This setting should be used with caution as it can cause damage if not handled properly.

What torque should I use on a drill?

When using a drill, the torque setting should be determined by the size and type of screw being used. Generally speaking, larger screws require higher torque settings than smaller screws. To ensure that you are applying enough torque to secure the screw properly without damaging it or your workpiece, use a lower setting for small screws and increase as needed for larger ones. It is also important to note that different materials may require different levels of torque when drilling into them. As such, it is best to consult manufacturer instructions before beginning any project.


In conclusion, understanding the numbers on a cordless drill can be intimidating at first. But with some basic knowledge of voltage, speed and torque, you’ll have no problem finding the right tool for your next home improvement project. Knowing what do numbers mean on a cordless drill will help you make an informed decision when it comes to choosing the best power tool for your needs. With this information in hand, you’ll be ready to tackle any job that comes your way!
