Understanding Torque: What Does Torque Mean and How Does It Impact Your Tools?

All too often, when purchasing a new power tool, we’re faced with an array of technical terms. One such derivative is ‘torque’. But what does torque mean, and how does it impact your tools? Let’s unravel this mechanical mystery.

Decoding Torque: What Is It?

Torque, quantified by the Greek letter τ, is essentially a measure of rotational force that articulates the twisting effect on an object. It’s a crucial cog in the mechanics and engineering machinery to ascertain the turning exertion on a thing. Units of measurement for torque include Newton-meters (Nm) or foot-pounds (ft-lb).

Torque finds a central role in the function of tools, especially those that require a twisting mechanism like screwdrivers or wrenches.

Torque and Your Tools: The Connection

Torque is integrally linked with your tools’ performance. In case of insufficient torque, there’s a risk of loose fasteners, leading to possible safety hazards or equipment failure. On the other hand, excessive torque may cause fasteners to break, posing similar risks. Therefore, a meticulous understanding of torque can aid in choosing the appropriate tool for a task and using it optimally to achieve desired results.

Torque Settings: The Power Regulators

Torque settings on your tool function much like the clutch on a car – when modulated, torque settings can vary the power and speed transferred to the wheels of the car. This feature on your tools helps make them more versatile as it lets you control the speed and power, giving you more control to complete a variety of jobs.

Torque – Balancing Power and Precision

If you’ve ever wondered why would you want your power tool to be less powerful, here’s why: applying inappropriate torque can result in several predicaments like over-driving your screws, stripping the screw head, or splitting the material you’re working on. All these issues emphasize the significance of understanding and correctly applying torque settings in different situations.

The ABC of Torque Settings

To avoid any tool-caused damages, getting your torque settings right is of the essence. When driving screws into harder materials or when drilling holes into tougher materials, it’s often best to choose a lower speed on the gearbox, which usually delivers more torque. This increases your control over the depth of your drilling and prevents any damages.

Tips for Selecting the Right Tool

More torque settings offer greater control while working. Here’s a guide to Newton Meters (Nm) on drills:

  • 4 to 15Nm: Ideal for smaller screwdriver tasks at home.
  • 15 to 40Nm: Perfect all-rounder for drilling and driving medium-sized screws and hole drilling.
  • 40Nm upwards: Handles serious projects with larger screws and holes efficiently.

Remember, a 2-speed gearbox generally yields a higher RPM (Revs Per Minute) than a single speed, giving even more control over the job.


Q. What does torque mean?

A. Torque is the amount of rotational force applied to an object. It can be measured in Newton-meters (Nm) or foot-pounds (ft-lb).

Q. Why is torque important in tools?

A. Torque is critical as it determines the twisting force a tool can apply, affecting its performance in tasks that involve rotating a fastener, such as a screw or bolt.

Q. Can applying the wrong amount of torque damage my tool or materials?

A. Yes. If too much torque is applied, it can strip the threads of a fastener or cause it to break. Too little torque can lead to a loose fastener, causing the object to be insecure.


To sum up, understanding what torque means and how it impacts your tools can make your work much more effortless, efficient, and safer. Not only does torque control the power and precision of your tools, but it also is key to enhancing the longevity of your equipment. So the next time you pick up a tool, remember – it’s all about the torque! Join us again for more insightful deep-dives into the complex world of tools and hardware.
