Buying a cordless drill seems simple—until you look at the specs. Voltage, torque, hammer function, brushed or brushless. The wrong choice can leave you with a tool that's too weak for the job, or one that's unnecessarily heavy and expensive for your needs. This guide will help you find the right machine for your work based on key specifications.
To avoid making the wrong choice, it's helpful to understand a few technical parameters. These specifications directly determine what you can do with the tool.
Voltage (V): The voltage indicates the battery's power and is an indicator of overall strength.
Torque (Nm): Torque, expressed in Newton-metres (Nm), represents the tool's rotational force. Higher torque means more power to drive screws into hard materials or drill large-diameter holes. Tools with adjustable torque prevent you from over-driving screws.
Brushless Motor: A brushless cordless drill has less internal friction than a traditional motor with carbon brushes. This results in more efficient energy use (longer battery life), more power, a longer motor lifespan, and less maintenance.
Functions: Driving, Drilling, and Hammering:

What is the difference between a drill driver and a hammer drill? A standard cordless drill (or drill driver) is designed for driving screws and drilling in materials like wood, metal, and plastic. A hammer drill adds an extra function that creates a pulsating, hammering motion along with the rotation. This hammer function is necessary to drill efficiently into harder materials like brick and masonry.
How many volts (V) do I need for my cordless drill? For most jobs in and around the house, like assembling furniture or drilling into wood and drywall, an 18V or 20V machine is an excellent all-rounder. They provide enough power without being unnecessarily heavy. For light-duty screwdriving only, a 12V tool may suffice.
What is a brushless motor, and is it worth the extra cost? A brushless motor does not have physical carbon brushes that make contact to power the motor. This reduces friction and heat generation. The advantages include higher efficiency (the battery lasts longer per charge), more power, a longer motor lifespan, and no need to replace brushes. For frequent or professional use, a brushless motor is typically worth the extra cost.
