Hitachi 18V Brushless Triple Hammer Impact Driver Review WH18DBDL2

Speed, Power & Finesse

img_20160922_132439313Hitachi introduced an industry first triple hammer impact driver that is very compact and more powerful than many others on the market.  Hitachi claims the triple hammer impact driver will tighten to 1,832 in-lbs of torque (152 ft-lbs of torque).  If you think about that, this tool will tighten 60 pounds tighter than what is recommended for most car lug nuts.  Not being all about power, this tool is compact and has modes that are designed for fine woodworking or cabinetry.  Also, if you are working with self tapping screws, there is a mode for those allowing for fast drilling then delicate impacting so heads of these screws are not snapped off.

If you are looking for a small impact that is smooth, powerful and will complete almost any job an impact driver can do, look no further, Hitachi nailed it.  They even took it one step further making the tool Ip56 rated.  This means the tool is dust resistant and water resistant to high powered water jets.  Reliability on the go, on the jobsite, or in poor weather is not a worry.

My Thoughts

img_20160922_125623989When opening up the tool the 1,832 in-lbs of torque stuck out so there was an expectation of a larger tool to accommodate an extra hammer and give it room to more.  There was a surprise when the case was opened and this tool is the size of most compact impact drivers.  Then there was some suspicion on the torque number, but once we read the instructions and found it to be a torque number based on fastening and not nut busting, we pulled out some large lags and went to work.

Due to the size of the tool, we started with 4″ lags and found this tool made very quick work of sinking them.  We moved up to 6″ lags and it still pounded them in without hesitation or wait.  The 3.0Ah battery was not breaking a sweat and handling the workload without issue.  Thinking this tool might be one of the most powerful impact drivers we have ever used performance wise, we toned it back to delicate woodworking settings.  The fine mode gave incredible control.  This tool has no issue giving you all the control needed for delicate work yet all the power one could ask for in a construction rated impact driver.

Beyond the power, small size and comforts, this tool is IP56 rated so we had to dunk it in water and spray it down with a hose at full pressure.  There was no slowing the tool and it kept working just like it came out of the box.  If you are looking for a small, lightweight workhorse that can take care of every task you would expect from a high end impact driver, take a look at this Hitachi.  We think you will be amazed by the tool.
