What’s the Best Impact Driver?
Ten brushless impact drivers put through their paces.
Synopsis: In this Tool Test article, David Frane tests out 10 brushless impact drivers to gauge speed and power. He describes the features of a basic impact driver at a glance, and then compares the weight, price, speed, and power of 10 impact drivers from 10 different makers before naming the Best Overall and Best Value winners.
Few power tools have risen so far so fast as the cordless impact driver. A once obscure tool that’s now an indispensable part of most tool kits, impact drivers sink screws, tighten bolts, and, with the right bits, drill holes. For this article, I tested 10 impact drivers: eight 18v models and two 21.6v models. I included the higher-voltage tools because they are roughly the same size and price as the 18v models, differing only in the number of cells inside their battery packs. All of the drivers have brushless motors, which boost runtime and allow…
