Torque

An impact driver’s torque (1) measures its power. Typically, it will be shown in RPMs. A higher torque makes an impact driver more suited to heavy-duty projects. 

Consider the kind of tasks you need to accomplish then choose a model that has the appropriate torque. If you’re planning to install, fence or decking, for example, you need a model with higher torque. On the other hand, if you need to assemble furniture or put up a shelf, a lower torque will suit.

Speed

You’ll find adjustable settings on the highest quality impact drivers. This is something you should therefore be looking out for. It means you’re able to change the driver’s speed to accommodate a range of materials. 

You need a low speed for driving screws into plasterboard, softwood and other delicate materials. A higher speed is necessary for hardwoods and other robust materials. Variable speeds means you can do more tasks with no concerns about damaging the screws or material.

Chuck Size

The chuck size (2) refers to the bit size you’re able to fit into your driver. You need to check this so you can be certain it meets your needs. 

A bigger max chuck size allows larger bits to be used. That means you can drive bigger screws. Having a wide range of chuck sizes is always a good idea for maximum versatility.

Best Cordless Impact Driver FAQs

Impact drivers are a form of cordless drill driver. However, rather than using a regular 13mm chuck, it has a ¼ inch hex bit holder. This grips smaller screwdriver bits. 

An impact driver is about high torque and high impact. Typically, impact drivers output a higher torque level than the best combi drills. This allows you to drive wide, long screws rapidly into tough materials.

Modern cordless power tools are often brushless these days. This means there are no brushes used to send electricity to the rotor. Rather, permanent magnets are used.

Brushed tools still have a place. However, brushless technology is now far better. It can offer you a longer lifespan and better performance overall.

It’s possible to use your impact driver as a drill. You’re able to make holes in softwood and light-gauge steel using a hex-shank drill bit fitted to your impact driver. To make bigger holes in hardwood or heavy steel, you’ll need to use an impact driver-rated bit.
