  • Powerful
Size: 2,500 In-lbs Style: w/2.5Ah + 5.0Ah Lithium Batteries
Great case that comes with a little bit of extra storage for bits and such. Great tool

  • 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

  • King of impacts
Size: 2,500 In-lbs Style: Tool Only
This thing is a monster. It has eaten everything I've thrown at it. Very powerful and I love that it has modes to be able to use some finesse instead of full brute power all the time. Quick eject is great. It's small, lightweight and feels great in my hand.

Very well built... A bit on the heavy side but not a deal breaker very happy with it... Tried other friends brands equipment but decided on this for my own.

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