When you’re working at height or just hate chasing rogue nuts and bolts, it’s incredibly helpful. In reverse, auto modes can back off a fastener and stop or slow down significantly so you don’t run it completely off. Having an automatic stop helps you run a nut or bolt quickly and still leave it short to finish off with a torque wrench. Many fasteners have a torque rating and it’s easy to over-torque them if you’re not careful. Electronic Assistance and Smart ControlsĪssist modes and smart controls are highly valued features for impact wrenches.
It’s common to use a class size smaller to get the same performance as larger models that are just one generation back.
Just keep in mind that today’s brushless models perform at a much higher level than before. You move up in power as you move up in size. In general, there are 3 primary categories to look at: compact (including stubby), mid-torque, and high-torque. Rising up to take the title of best cordless impact wrench in any category requires a lot of attention to the power-to-weight ratio. Most impact wrenches are much heavier than impact drivers, and the vibration and noise of the tools can fatigue you quickly. Once you know how much power you need, finding it in the smallest, lightest package you can without giving up on quality is high on the list. If you’re in construction or landscaping where you’re running long timber screws and the like, you want to run those as fast as you can while keeping them under control. The more power you have, the better chance you have of getting the fastener moving quickly and not straining the motor. Whether you’re fastening or loosening, power is the name of the game for cordless impact wrenches. Buy at Acme Tools What We Look For When Testing Cordless Impact Wrenches Power and Speed
