The highest battery capacity (20-volt) is usually reserved for contractor-quality drivers.
IMPACT DRILL DRIVER
The higher the capacity, the longer the battery life and the more power the driver will generate.
IMPACT DRILL DRIVERS
Battery: Cordless impact drivers run on rechargeable batteries in 12-volt, 18-volt, and 20-volt capacities.A small impact driver with 800 inch-pounds of torque is sufficient for driving screws in a workshop setting, while an impact driver with 2,000 inch-pounds of torque is better suited for driving multiple large screws, such as those used to construct the frame of a house.
The higher the torque (measured in inch-pounds), the more twisting power.
IMPACT DRILL PROFESSIONAL
Less powerful models are suitable for workshop and DIY projects, while more powerful drivers will tackle the insertion of large screws, making them a good choice for professional contractors. Power is the most important aspect of impact drivers. Key Considerations When Choosing an Impact Driver Impact drivers are superior at directing their force downward, making them more comfortable to use over a long period of time. This hex-bit design is necessary to accommodate the power output of impact drivers. Instead, they feature a quick-change clamp that holds drill bits and driver bits with a hexagonal shank. Unlike a drill, impact drivers do not have a chuck. As the voltage increases, so does the power and speed of the impact driver. These tools are available in cordless designs ranging from 12 volts up to 20 volts. It also has more torque than a power drill. Impact Drivers: An impact driver is more compact and lightweight by design.A power drill is an adjustable-speed tool that drills and drives in fasteners. Standard bits and hex bits are available for ultimate versatility. The drill’s head features a keyed or keyless chuck that holds the bits securely in place. Drills: A standard drill driver is one of the most essential all-purpose tools.Both are offered in cordless and corded models, and both offer a reverse direction setting. These two power tools look similar and perform similar but different functions. Many Pros use them in tandem with a drill driver to drill a pilot hole and then drive a fastener without switching bits. In general, they’re lighter and more compact than drill drivers or hammer drills. It makes these tools easier on your wrists for hard stop driving applications. The mechanism works without transferring rotational torque to your wrist. This keeps the screw moving forward when it starts getting tougher to move. They have a rotational impact that comes from a hammer and anvil mechanism. While you can use an adapter to use sockets and work with larger nuts and bolts, an impact wrench is typically a better tool for that. For our purposes, we drive screws up to 1/4-inch diameter. Pros typically use impact drivers to drive screws using bits such as Phillips, Torx, or even hex head bits. We subjectively judged the comfort and ergonomics of each driver, but we also beat the heck out of them by effectively maxing out their torque capabilities. We measured, weighed, and timed dozens of variables but also looked for tiny details such as the usability of the bit holder as well as the pattern and effectiveness of the target lights. During our quest to find the best cordless impact drivers, we bought and tested the 20 most promising models on the market to put in a head-to-head, hands-on, battery-powered tool showdown.
