Hitachi WH12DMR User Reviews Highlights

  • This drill is easy to use and powerful. Wish they would make it in a lithium-ion battery model.

  • A very good lightweight driver for lighweight jobs. Extremely powerful for its size. Good battery.

  • I've bought 3 of the Hitachi 12 volt Impact drivers and they are great!

  • At slower speeds the unit will tighten precisely one click at a time, giving you perfect control over setting screw depth/torque.

  • I just can't say enough about this tool. Its the only thing I have found that does a nice job on tapcons into concrete, and does it without twisting your wrist off, try that with your 18 volt dewalt.

  • This is a great tool. It is compact, well balanced, powerful and long lasting.

  • It easily drives the 3-1/2" #9 trim head jamb extension screws that are needed for Anderson 400 series windows in 2x6 walls.

  • Bought this for a friend and he is extremely happy with the product.

  • I've owned this little driver for a few months now and I reach for it every time i need to drive drywall screws to quarter inch lag bolts.

  • I am completely satisfied with this tool. I have let other guys on the job use it and have gotten nothing but praise.

  • We took a phillips driver and drove a 6" wood screw into a couple two by fours and it literally sent the thing through it with out hardly having to use any pressure.
