Our Opinion

Power Packed in Every Punch

The most popular feature of the Hitachi WH18DGL Cordless Driver is its speed and strength. For a tool widely considered as small by industry standards, it sure can pack a lot of power in every punch. This driver has a maximum torque strength of 1,280 inches per pound and boasts an astounding 3,200 impacts per minute. The average IPM of 18V cordless tools in the market is only 3,016.

Aside from this, the WH18DGL also has a top speed of 2,400 revolutions per minute. This speed coupled with its torque strength allows you to screw and tighten bolts more efficiently.

A variable speed trigger located in the middle of the driver also allows you to control the IPM and RPM more conveniently. Not only does it give you total control of both the speed and the impact of the driver but it also enables you to do a wider variety of jobs.

Truly, the flexibility that the Hitachi WH18DGL Cordless Driver gives you makes it an essential tool to have at home. It can handle heavy-duty tasks such as carpentry work or mechanical repairs, but it can also be used for everyday chores such as fixing cabinets, re-aligning shelves, or even just tightening bolts at home.

Design Features for Everyday Use

Another amazing feature of this product, which is often overlooked, is its practical design. What sets this tool above the rest of the competition are not only aesthetically pleasing qualities, but it likewise serves a fundamental purpose of improving your work conditions.

The first thing I would like to talk about is Hitachi’s innovative lightweight design. Like what was stated above, this tool is packed into a very compact 3.1 pounds, which therefore requires minimal effort when using it.

This driver also comes with an LED light that illuminates automatically when you press the speed trigger. It gives you the ability to work longer and more efficiently in all types of workspaces, such as ceiling projects, basement repairs, or even maintenance tasks under your car.

Convenient Bit Functionality

Located in the top of portion of the tool is a ¼-inch quick-change chuck. As its name suggests, it allows you to change bits more efficiently. Even without a torque adaptor, this gives you the same flexibility that other cordless drivers offer and allows you to do a broader range of work in a jiffy.

You can also store bits you are not using in a space located at the bottom of the driver, giving you a more convenient location to access them when you need to. This may seem like a small innovation, but it offers you the option of keeping and changing your drill bits easily.

Innnovative Battery Technology

One of the most significant problems when using power tools is their chosen battery’s short lifespan.  With the power requirement of the WH18DGL, it is easy to write it off as having the same problem. However, since it is powered by an 18V lithium ion battery, it gives users three times as much life compared to other traditional variants. This allows you longer and more efficient work hours without having to worry about your cordless driver running out of juice.

The driver also comes with a fast charger that renders an average charging time of only 35 minutes. With this kit, you get an extra battery as well. These features not only save you a lot of time but also help conserve electricity, saving you a ton of money in the process.

Hitachi Lifetime Lithium Tool Warranty

Hitachi is not only committed to providing you with quality power tools, but it also pledges a solid after sales service. In 2010, Hitachi launched its Lifetime Lithium Tool Warranty which states that there is no expiration of service warranty for lithium tools. This means that if you want to have your cordless driver checked or fixed, you can bring it to any accredited Hitachi service center free of charge. A special two-year warranty also applies to the battery as well as a one- year coverage for the fast-charger.

Comparison with Hitachi WH10DFL2

The main difference between the WH10DFL2 and the WH18DGL is the additional torque strength of the latter. The maximum power that the WH10DFL2 can give you is only 955 in. lbs. as compared to the other’s 3,200. The added torque strength allows you to do a wider variety of jobs and is more suited for heavy-duty projects.

Another take away here is the price difference between the two products. Inherently, both tools possess the same specs, but you would be giving up nearly three times as much torque strength, while only saving about $10 in the process.

Therefore, if you are looking for a quality cordless driver for basic uses around the house, then you can settle for the WH10DFL2. Nevertheless, if you need one that will give you more extensive flexibility and greater power, then I strongly suggest you buy the WH18DGL instead.

Conclusion

After talking about all the features of this particular impact driver, it can be said that it is a perfect and essential power tool for any home or workhouse. It not only possesses a top of the line torque strength but thanks to its lightweight design and 18V lithium ion battery, it gives you the ability the work longer and more efficiently.
