When it comes to making quick work of big fastening jobs, nothing beats an impact driver. From driving in long deck screws to loosening corroded bolts, these tools zip through projects that wouldn’t be possible with a standard screw gun or power drill. To get the most out of your impact driver, you need to invest in one compact enough to use comfortably but still powerful enough to tackle the task at hand.
Why do you need an impact driver?
If you already own a power drill, you may ask yourself why you need a tool that appears to perform the same action. While drill guns are great for making holes and driving short screws through soft materials, they fall short in the torque department. Thanks to their additional power and concussive hammer action, impact drivers can twist screws through thick wood and tighten up metal hardware without the risk of getting stuck or burning out. Because impact drivers deliver so much torque, you can even skip the pilot holes in many cases. This alone can save you hours of time throughout a project.
What is torque?
Simply put, torque is a measure of rotational or twisting force measured in pounds-feet. Extreme delivery of this force is the standout feature of an impact driver. A driver capable of achieving around 1,500 pounds-feet of torque is acceptable for most jobs, although some exceptionally powerful tools can approach 2,000.
What to look for in an impact driver
Torque delivery alone does not make one impact driver necessarily more appropriate for you than another. Keep the following considerations in mind to make the best purchase for you:
- Small profile. Compact tools are easier to maneuver, carry and store.
- LED lights. LED lights around the tool’s bit help you see what you’re doing in poorly lit spaces.
- Weight. A heavy tool can wear out your arm and wrist well before quitting time. Look for the lightest impact driver you can find, keeping in mind that a battery will add some additional heft.
- Voltage. The higher the voltage, the higher the torque. Select a 20-volt driver for maximum power.
- Brushless motor. Brushless motors generate energy more efficiently.
- Quick-release nut. Opt for an impact driver with a quick-release system so you can swap bits on the move.
- Included accessories. The cost of batteries, storage solutions, bits and belt clips can add up. Many manufacturers offer money-saving sets that include everything you need to get to work.
- Variable speeds. Choosing a driver with selectable speed settings gives you more flexibility and prevents you from draining the battery on jobs that don’t demand full power.
