Description

It delivers 600 foot-pounds of fastening torque and 750 foot-pounds of nut- busting torque for demanding jobs. When used for automotive applications, Bolt Auto Stop Mode prevents over-tightening, breaking, or stripping of lug nuts while Bolt Removal Mode stops the tool when it senses the lug nut is loosened. Vibration suppression isolates the ½-inch impact wrench and user from vibration for more comfortable extended use, and three speed modes plus a variable speed trigger allow easy control of RPMs to adapt to different materials. This cordless impact wrench dominates with the FLEX Stacked Lithium Advantage: unmatched battery power, runtime, and charging capability. The cordless impact wrench set includes the mid-torque impact wrench, a 3.5Ah Stacked Lithium battery, and 160W Fast Charger. It’s all protected by the FLEX Limited Lifetime Warranty when registered within 30 days of purchase atthrough December 31, 2024.

  • Actually Pretty Nice!!!
Size: 1,150 Ft-Lbs Style: w/5.0Ah Lithium Battery
For the price it's actually pretty good. The torque is amazing and exactly what I need it for. The weight of it is heavier than your standard impact so keep that in mind. The battery last quite awhile and it charges super fast. THE HEAD OF THE IMPACT IS SUPPOSED TO ROCK BACK AND FORTH!!. I see a lot of reviews about the head of this impact rocking back and forth but it is made that way, it's the "anti kickback" feature it has. Very impressed with this impact and I highly recommend! ... show more

  • Worth every penny!
Size: 1,150 Ft-Lbs Style: w/5.0Ah Lithium Battery
I got this on sale for $199. Definitely a great value for the power! Battery charges fast, Impact itself is powerful and durable. Packing and color scheme is sleek. Will definitely continue to purchase Flex tools

  • heavy duty and battery indicator super easy to see
Size: 1,150 Ft-Lbs Style: w/5.0Ah Lithium Battery
Just used it a few times so far, but battery still has all 4 bars (charged it once i got it). Tool feels like it has plenty of torque and the battery indicator is a super bright green that's easy to see even in the brightest daylight. Only drawback would be if you aren't used to really heavy impacts this one is up there with Milwaukee but all high torque impacts that are decent will be heavy. ... show more

  • This thing is a brute!
Size: 1,150 Ft-Lbs Style: w/5.0Ah Lithium Battery
I was actually in the middle of a fairly involved, heavy job on one of my vehicles, when this thing arrive. I had taken most of the front suspension and drivetrain apart the day before, using hand tools and my pneumatic impact wrench. Then this FLEX cordless impact showed up on my doorstep that evening so I used it on the re-assembly the next morning. Wow, this thing packs a punch! Yeah, it's heavier than my air impact due to the weight of the battery and motor, but it's so nice to not have to drag the hose around everywhere or hear that air compressor running. The battery lasted all day with fairly heavy use, plus for a few more small jobs over the following days before I finally put it back on the charger (not even sure if it needed it yet). My only complaint, and it's a minor one, is that the little socket keeper ring on the driver head is a bit too tight, making it a bit of a struggle to get sockets on to it. Perhaps that will loosen up a bit with more use. ... show more

  • Terrible
Size: 1,150 Ft-Lbs Style: w/5.0Ah Lithium Battery
This is the 2nd one I received as my replacement. I didn't even use it. I wanted to check if it has the same issue and here you go. The 1st one I received at least I was able to use once. Never buy this.

  • Way More Powerful Than My Other Torque Wrench
Size: 750 Ft-Lbs Style: w/5.0Ah Lithium Battery
I picked up the FLEX 24V Brushless Cordless 1/2-inch 750 Ft-Lbs Mid-Torque Impact Wrench Kit to keep in my father's garage for bigger vehicle projects. I do a lot of work on my own vehicles and at times my parent's vehicles. I have another smaller impact wrench kit I've been using over the past couple of years, but when it came to changing my brakes it was just useless without an actual wrench wrench. Now, with this torque wrench, I've had zero issues taking off the lug nuts and when I put them back on I barely need to torque them with a large levered torque wrench to ensure the wheels are completely locked onto the vehicle. Overall, I absolutely love this FLEX 24V Brushless Mid-Torque Impact Wrench. So, if you're shopping around for an industrial-style heavy-duty cordless torque wrench, I'd strongly urge you to take a strong look at this one. ... show more
