Makita XDT16Z Lithium-Ion 18V Review
A powerful driver with a great battery life that's a fairly large investment

Our Verdict
The Makita XDT16Z is one of the highest-performing impact drivers we've tested. It maxed out our torque tests and offers lightning-fast speed. It has one of the longest-lasting batteries out there and has some amazing bonus features, such as an awesome light and eight different speed and torque settings. Like most impact drivers, the XDT16Z is loud. The main reason why it failed to earn an award is its high cost. Unless you already own the compatible battery and charger for this model and are able to find a place to buy the tool on its own, there are less expensive versions available that offer a comparable performance.
Our Analysis and Test Results
The Makita XDT16Z is one of the fastest and strongest impact drivers that has ever come through GearLab headquarters. When it comes to 18-volt models, the 16Z's battery life is unmatched. If you already own Makita 18-volt lithium-ion batteries, this model should certainly be on your radar.

Speed
This model was one of the fastest drivers in our speed assessments. It takes an average of four seconds to sink a 3 ⅝" ledger screw into a stack of douglas fir 2x12s. When it came to driving a 3" x ½" lag bolt into the same stack of boards, the 16Z only took 14 seconds to sink the screw and an impressive five seconds to remove it.

Torque
Our torque tests were another strong suit for the Makita XDT16Z. This was one of the few models to completely max out our assessment apparatus. The XDT16Z was able to tighten large nuts to 300 foot-pound and had no problem loosening nuts tightened to the same pressure.

Convenience
When it comes to convenience, the Makita XDT16Z is one of our favorite models to use. With an overall length of 114 mm, this version is small enough to squeeze in between wall studs, under sinks, and into the tiniest of attic and crawlspace spots. It has eight different modes, including four assist and impact modes, allowing you to customize the settings for any project.

We love the quick-insert chuck on the Makita XDT16Z. This feature allows you to stick a bit into the tool with one hand and know that it will be secure without double-checking it while you're searching for a fastener on top of a ladder or on your back in a crawl space.

Battery
The Makita XDT16Z has stupendous battery life. To test battery life, we alternated between sinking fourteen ledger screws and setting a large lag screw in and out of a pre-determined size and type of lumber and gave out points according to the number of sets that each model could complete. The Makita crushed five sets of our gauntlet before running out of juice on the 10th screw of the sixth set.
Many, many screws were sunk for the sake of wearing these batteries out.

Noise
The Makita XDT16Z is far from the quietest model in our review, but it is by no means the loudest. With an average sound level of 96 decibels, it's probably not the best model to operate while your neighbors are enjoying dinner.

Should You Buy the Makita XDT16Z?
The XDT16Z is definitely the right impact driver for certain people. If you require ultra-high performance from a tool with minimal bulk, this model is the way to go. Also, if you already own Makita 18-volt lithium-ion batteries, you can save a good chunk of change by buying the tool by itself.
What Other Impact Drivers Should You Consider?
In the realm of impact drivers, if you want super-high performance, you're going to have to drop the extra coin. Unfortunately, the Makita XDT16Z is pricey. You may not need an 18-volt version at all. If you need a driver that is light and will take care of most light installations, tinkering, and adjustments around the house, then check out the Milwaukee M12 Fuel.
