  • A Killer Deal
Size: 2,500 In-lbs Style: w/2.5Ah + 5.0Ah Lithium Batteries
I have a Milwaukee impact driver drill, the really good one that competes with this Flex 1371 model, but it cost me an arm and a leg. The Milwaukee is REALLY expensive. You can get a decent deal at the home depot when they are on sale , still, the really good Milwaukee batteries are very expensive. I just purchased this Flex 1371 with two batteries for less than $200 bucks. This is simply unbeatable. This Flex drill is sick and it is a BEAST! ... show more

  • ITs a workhorse
Size: 1,700 In-lbs Style: w/2.5Ah Lithium Battery
The FLEX 24V Compact Impact Driver is a powerhouse disguised as a lightweight tool. Despite its smaller frame, it packs enough torque to handle most jobs without breaking a sweat. The brushless motor means smoother performance and longer life, and paired with the 24V battery system, you get hours of reliable runtime before swapping packs. The multiple modes — especially the self-tapping screw mode — make it versatile for everything from furniture builds to tougher construction tasks. Sure, it’s not meant to replace the monster full-sized impacts for driving lag bolts into hardwood all day, but that’s not its purpose. For daily use, especially in tighter spaces, it shines. If you’re already invested in FLEX’s 24V platform, this driver feels like a no-brainer upgrade — compact, efficient, and genuinely fun to use. ... show more

The driver seems well made and powerful but two negative observations 1) It’s heavy 2) The torque is not adjustable

I ordered this after my Dewalt ran hot screwing in 3” Deck screws on new deck. Ordered the Flex after reading reviews and it has lived up to expectations so far.
