There are two main types of cordless impact screwdrivers . The first type looks like the cordless screwdriver, but it is rather elongated. It’s a suitable solution for accessing tight corners and spaces. The second type looks like a small electric screwdriver, and it’s generally more powerful. The electric screwdriver is similar to the drill-driver. You can use it to screw furniture kits or soft materials. Most power screwdrivers have a voltage of 3.6 volts and some professional models like the battery screwdrivers can reach a voltage of 7.2 volts. We recommend a minimum of 6.0 volts so you can screw effectively in wood and soft materials. When you purchase cordless impact screwdrivers , you should also look for the tightening torque (besides the voltage). The resistance of screwdrivers in the materials is expressed in N (Newton Meter). We recommend a tightening torque between 3 N and 4 N, but for regular use, you can opt for 5N or more! Now that you have the voltage and tightening torque in mind, you can select your cordless impact screwdrivers from an extensive wholesale collection that includes: impact screwdrivers, automatic screwdrivers, rechargeable screwdrivers, battery-powered screwdrivers, and drill screw bits. Quality doesn’t necessarily mean expensive, we have some great screwdrivers at attractive prices.
