Ergonomically Designed

Hitachi WH10DFL2 12-Volt Peak Cordless Lithium Ion Impact Driver Kit (Lifetime Tool Warranty)This impact driver is ergonomically designed with its compact, extremely lightweight size and great handling features. It weighs just less than 3 pounds and measures 5.9 inches. In addition, with the slim batteries, the weight is evenly distributed which adds to its ease of use.

The handle sits comfortably in the hand and can be used by women or those with small hands. The trigger and direction controls are conveniently located on the drill where they can be operated without changing your grip on the handle. That is easy maneuverability especially for working in tight spaces.

The WH10DFL2 is protected by the green rubber that is wrapped around it, keeping it safe from everyday damage and abuse. This rubber also serves well as a shock absorber from all the impacts delivered during regular use. The black parts are not rubberized but are covered with a textured plastic surface that also feels good on your hands.

The built-in LED light is turned on at the first squeeze of the trigger even before the bit starts spinning. You can actually see your work area before you begin the driving process. This is a really convenient feature that you will find useful when working at night or in poorly lit or confined spaces.

Hitachi Lifetime Warranty

Hitachi WH10DFL2 12-Volt Peak Cordless Lithium Ion Impact Driver Kit (Lifetime Tool Warranty)Most brands give out three or five-year warranties for the tools they sell. Well, not Hitachi. The company is very confident about its quality that it could afford to give you a lifetime warranty. Moreover, you also get two years warranty for the lithium ion battery.

However, the same conditions apply to this coverage as those of other brands. Any damage inflicted upon the unit due to the user’s negligence will void this feature. In addition, repairs on the unit should only be done by recognized personnel.

Comparison with Hitachi WH18DGL

The Hitachi WH18DGL delivers 1,280 in. lbs. of maximum torque as compared to the 955 of the WH10DFL2, which means the former is more powerful and can handle tougher tasks. However, when we talk about speed, the former’s 2,400 RPM pales in comparison to the latter’s 2,700. Other than power and speed, these impact drivers share basically the same excellent features like the use of lithium ion batteries and a built-in LED light among many others.

The WH18DGL is an 18V impact driver while the other is 12V which forms part of the reason for the difference in power and torque. As far as affordability is concerned, and if it is one of your major considerations, then the WH10DFL2 is a good option as long as you don’t mind the inferior power. However, if you’re on the lookout for a reliable tool that’s strictly for home use, then either of two will prove to be very efficient and reliable.

There have been complaints of the WH10DFL2’s slightly loud noise level when being used. We measured it to be 107.9 decibels, the average noise level among 12V impact drivers. The reason this is even being discussed is that we hardly can find any fault with this impact driver. Some may look at its power as lower than its counterparts, but it is sufficient enough for most home projects. Unless you’re looking for a workhouse tool, this model is more than sufficient for your day to day needs.
