Test thread tolerance in seconds. A time-saver for high-volume work, these drivers quickly thread gauges in and out of holes for you—just pull the trigger. A green ring lights up to let you know your internal threads are within tolerance. If they're not, the gauge won't thread in fully. To avoid jamming, these drivers reverse gauges out of holes as powerfully as they thread them in. The pistol grip minimizes hand fatigue during long periods of use.

These drivers have two speeds to suit the job you need. The high speed works for most applications, while the lower speed is ideal for your largest thread sizes, or when you need more torque. Fine-tune torque even further with the included torque adjustment tool. These drivers come with two batteries, so you’ll never be attached to a cord or without power. Use one battery while charging the other.

Get started by placing your threaded plug gauge in a thread adapter (sold separately), then insert the adapter into the driver’s chuck. The adapter quickly attaches and detaches from the chuck to easily swap out different sizes of threaded plug gauges.
