An impact driver is a tool that drives bolts and screws into various materials. In other words, the handheld tool works like a traditional cordless drill. Only it’s designed to move large fasteners that would.

Benefits of an Impact Driver

An impact driver fastens two different materials.

Higher torque: The rotational force of an impact screwdriver is five times more powerful than a regular drill’s.

Easy to use: The tool is not only smaller and lighter but also has a shorter head for a terrific grip.

Uses vital bits: An impact screwdriver is made to work with hex-shank bits, which are pretty strong and won’t get snapped quickly.

Motor-powered: Most impact screwdrivers run on batteries, and you need little effort to operate them.

You don’t want to use an impact driver in certain situations, including the following.

  • Situation 1. Drilling Holes

While an impact driver can drill a hole, it’s not fit for the job. The high torque the tool produces could end up over-drilling the spot. The spot might not be as precise, too, as impact screwdrivers have limited control.

  • Situation 2: Working with Non-Hex Shank Bits

These power drivers work with specially designed hex-shank bits, which can withstand the additional torque associated with impact drivers. So, save your regular driver bits (non-hex shank bits) for when you’re using a hand drill.

  • Situation 3: Working with Short Screws

An impact screwdriver is made to drive large fasteners, including lag bolts. Driving short screws with the tool could get the screw heads snapped. You’re likely to overtighten these, too, which can crack the fastened materials.

  • Situation 4: Fastening Soft Materials

Due to its high rotational torque, a power drill is unsuitable for driving fasteners through delicate materials, including softwood. Otherwise, it could quickly get these materials damaged.

  • Situation 5: Precision Work

Precision jobs that a hand drill can handle well. The tool isn’t ideal for precision work. It’s just that an impact screwdriver is a tad difficult to control due to its back-and-forth banging action.

How to Choose the Best Impact Drivers

Here are some factors to consider when choosing impact drivers.

An impact driver helps drive a screw.

Impact drivers help drive a screw.

Voltage: The more voltage an impact driver has, the higher the torque it will produce.

Motor type: Drivers with brushless motors last longer, are more efficient, and generate less heat than their counterparts with brushed motors.

Speed settings: Go for a driver with variable torque settings, so you have an extensive RPM range to explore.

Advanced controls: You might want to grab a driver with a setting that locks the trigger for safety purposes.
