Battery Life

The Makita DTW190Z comes with a powerful 18V LXT Lithium-Ion 3.0Ah battery that provides enough juice for most applications. The battery is designed to last through repeated fastening and driving applications with its large capacity.

In terms of runtime, users can expect around 600 screws driven per full battery charge. This makes it suitable for most small to medium sized projects. The battery also features Makita's Extreme Protection Technology, which helps protect it from overheating and overdischarging.

One downside is that only one battery is included in the kit. So you may want to invest in a second battery if you plan on doing extended work. But overall, the battery life is quite respectable and on par with other leading 18V impact drivers in this class. Just be aware that repeated high torque fastening will drain the battery quicker than lighter duty driving.

Noise Level

The Makita DTW190Z has an impressive noise rating of only 84 dB under load. This makes it one of the quietest impact wrenches in its class. Most competitors have noise levels around 90 dB or higher, which can become fatiguing during extended use.

The DTW190Z manages to keep noise down thanks to its precision-machined gears and internal mechanisms. There is very little vibration or rattling during operation. The noise is more of a muted, steady hum rather than the shrill sound you might expect from an impact wrench. This helps reduce operator fatigue and makes communication easier on a noisy job site.

At just 84 dB, you can comfortably use the DTW190Z for hours without hearing protection. The noise output is comparable to a food blender or garbage disposal running. While you wouldn't want to use it all day next to your ear, the noise level is very reasonable for an 18V impact wrench with this much power. Overall, the DTW190Z strikes an excellent balance between power and noise.

Additional Features

The Makita DTW190Z impact wrench comes with several handy additional features that improve the functionality.

LED Light

It has an LED light that illuminates the work area. This helps when using the tool in dimly lit spaces or at night. The light automatically turns on when the trigger is pulled.

Reverse Rotation

The tool allows you to switch between forward and reverse rotation with a simple selector switch. This makes it easy to loosen and tighten bolts without needing to change grips. The reverse function is great for removing rusted or over-tightened bolts.

Speed Settings

The DTW190Z has 3 speed settings to match the power and speed to the application. Speed 1 is for precision work, while Speed 3 delivers maximum torque for the toughest jobs. This level of control allows you to use the right amount of power and avoid damage.

Accessories

The Makita DTW190Z comes with everything needed to get started right out of the box. It includes the 1/2" impact wrench, a 3.0Ah 18V LXT Lithium-Ion battery, and an 18V LXT Lithium-Ion rapid optimum charger.

The included 3.0Ah battery provides sufficient power for most applications. However, for extended use or maximum power, an additional higher capacity battery like the Makita 5.0Ah or even 9.0Ah battery can be purchased separately. This allows you to keep working non-stop by swapping out batteries.

For accessing tight spaces, a right angle attachment can be handy to have. Makita makes a 1/2" right angle attachment that works seamlessly with the DTW190Z.

To help protect your sockets, a impact socket adapter set is recommended. These will hold up better to the forces of an impact wrench compared to standard chrome sockets. Makita's impact socket adapter set goes up to 32mm.

That covers the key accessories. With the charger, battery, and impact wrench itself, the DTW190Z comes with everything needed to handle most jobs right out of the box. But for extended use or frequent heavy-duty use, extras like a higher capacity battery, right angle attachment, and impact socket set will maximize its capabilities.

Ease of Use

The Makita DTW190Z impact wrench is designed for easy and comfortable operation. The compact size and ergonomic grip make it easy to handle and maneuver into tight spaces.

Changing bits is a breeze with the quick release chuck that allows for easy bit changes without any additional tools. Simply pull back the ring on the chuck and insert the desired bit.

Operation is straightforward with a variable speed trigger that provides good speed control. There's also a forward/reverse selector switch conveniently located for thumb operation. The variable speed trigger starts slow and ramps up speed giving you precise control especially for delicate tasks.

Overall the Makita impact wrench is very easy and intuitive to use right out of the box. The great ergonomics, quick bit changes, and variable speed trigger result in an impact wrench that's a pleasure to operate.

Maintenance

Proper maintenance is key to ensuring your impact wrench performs optimally for years to come. Here are some tips:

Cleaning - Over time, dust and debris can build up in the tool which can cause overheating and premature wear. Blow out dust routinely with compressed air. Wipe down the housing and anvil with a clean rag. Avoid submerging the tool in liquid.

Storage - When not in use, store the wrench in a clean, dry place out of direct sunlight. Avoid exposing it to extreme hot or cold temperatures. Remove the battery before storage.

Replacing Brushes - The motor brushes will eventually wear down and need replacing. Check them periodically for wear. When they reach their wear limit, replace them with identical brushes from Makita. Follow the steps in the user manual for proper brush replacement. Only use OEM brushes to ensure optimal performance and safety.
