Hitachi WH18DFL User Reviews Highlights

  • Lightweight, works great, saved me from stripping a lot of screws.

  • Light weight and powerful. Can't say enough good things about it.

  • This is an excellent product for the price. I drilled about 400 pieces of 2x4 studs to create arch designs for stucco and it performed with ease.

  • Nice impact driver. Good battery life. Has more torque than my Bosch 36v Litheon drill.

  • So far I have been able to drive 4" lag screws into 6x6 pine as a test. It goes through like butter, if you're not careful you can drive the heads all the way through the timber.
