Best Cordless Impact Driver Buying Guide
Before buying any impact driver to complete your maintenance tasks, you should consider the following.
- Torque and speed: An impact driver must have good torque so that you can use it as a drill driver for boring big holes. Usually cordless impact drivers have two-speed ranges. Low RPM of 300-400 with greater torque which allows driving screws and high RPM of 1200-1500 RPM for drilling purposes.
- Cordless: A cordless impact driver is compact in size so you do not have to worry about continuous power as they are battery based. You can carry cordless impact drivers anywhere as they are powered by batteries.
- Not a hammer drill: When you buy an impact driver, it can be a substitute for a drill driver to some extent but it is usually not a substitute for a hammer drill as impact drivers can generate good torque but not powerful forward blows. Very few impact drivers can be a substitute for hammer drills.
- Comfortable for holding: While making your choice about the best impact driver, you must consider its weight before buying. The driver should not put added pressure or weight on your body as some tasks require the constant holding of the impact driver like attaching deck boards. So, make sure the material on the grip is non-slip and gives your ergonomic control to do your regular tasks. If you have compromised wrist condition, choose lightweight drivers.
- Batteries and chargers: Always consider battery life and charger performance before making a decision about impact driver. A long battery life with lithium-ion batteries can provide a high charging rate as compared to other batteries.
Aforementioned is a list of ten impact drivers where almost all can serve the purpose of a drill also but only a few can work as a hammer drill. When it comes to choosing the best cordless impact driver, it is only you who can decide which one can work best for you depending on your needs.
Milwaukee 2462-20 M12, Makita XDT111 and Ryobi One + P 236 impact drivers seem some interesting choices for conducting light to medium range fastening, drilling and driving tasks due to the incorporated torque, speed setting and the structure which can sustain external pressures.
You should make your decision about buying the best cordless impact driver based on your working requirements, the weight you can handle and speed and torque you need for the on-site job.
