Our take on the FLEX 24V Brushless Cordless 1/2-Inch 750 Ft-Lbs Mid-Torque Impact Wrench Kit with 5.0Ah Lithium Battery and 160W Fast Charger - FX1451-1C

The Flex FX1451-1C is a 24V brushless mid-torque impact wrench kit rated at 750 ft-lbs of nut-busting torque, sold with a 5.0Ah battery and a 160W fast charger. It stands out with two auto modes: Bolt Auto Stop to prevent over-tightening and Bolt Removal Mode that stops once the bolt is loose, plus three speed settings and vibration suppression. That puts it in the same class as mid-torque cordless wrenches from Milwaukee, DeWalt and Makita, with the Flex 24V platform's cross-compatibility as its main draw. It suits home mechanics and light professional work on lug nuts and suspension bolts rather than heavy diesel or industrial jobs.

About the FLEX 24V Brushless Cordless 1/2-Inch 750 Ft-Lbs Mid-Torque Impact Wrench Kit with 5.0Ah Lithium Battery and 160W Fast Charger - FX1451-1C

This is a 24V brushless cordless impact wrench kit with a 1/2-inch drive and 750 foot-pounds of torque. It includes the impact wrench, a 5.0Ah lithium battery and a 160W fast charger. The tool has a sensor-free brushless motor built to reduce friction and improve efficiency and power.

Two auto control modes help with fastening and removal. Bolt Auto Stop Mode prevents over-tightening, breaking or stripping. Bolt Removal Mode stops the tool when the bolt is loosened. Three speed modes give more control while fastening bolts, and vibration suppression isolates the tool and the user from vibration.

The system uses THERMA-TECH heat management and high-power, dual fan chargers. It is compatible with all FLEX 24V batteries, chargers and tools.

Questions and answers

Is 750 ft-lbs enough for lug nuts?
Yes for most passenger cars and light trucks, which typically need well under 150 ft-lbs of tightening torque. The 750 ft-lbs is nut-busting torque for loosening, so it handles most stuck fasteners. Very tight heavy-duty or rusted bolts may need a high-torque wrench.
What is in the box?
The kit includes the impact wrench, one 5.0Ah 24V lithium battery and a 160W fast charger. It does not include a second battery or a case.
What do the auto modes do?
Bolt Auto Stop Mode stops the tool to prevent over-tightening, breaking or stripping a bolt. Bolt Removal Mode stops the tool once the bolt is loosened so it does not spin off.
Does it use the same batteries as other Flex tools?
Yes. It is cross-compatible with all Flex 24V batteries, chargers and tools, so one battery line covers the whole range.
How does it compare with a high-torque impact wrench?
It is smaller and lighter than a high-torque model but has less torque. It suits lug nuts and general automotive work; heavy diesel or industrial fasteners call for a high-torque wrench.
How do I get the lifetime warranty?
Register the tool, battery or charger through Flex within 30 days of purchase. Registration must be completed by December 31, 2025 to qualify for the limited lifetime warranty.
