Impact driver 1/4" 180NM 18 V LXT 5.0 Ah BLDC DTD173RTJ

Precision and Power in a Compact Housing

This tool stands out from the competition thanks to its 4-stage electronic switch, which allows precise adjustment of rotational speed and impact frequency to suit specific tasks. Instead of a single, fixed setting, the user gains full control: from delicate tightening of small machine screws (M4-M8) at 1100 rpm, up to assembling heavy structural components up to M16 with torque reaching 180 Nm. Such flexibility is crucial both for finishing work requiring caution and for demanding construction conditions needing high clamping force.

The brushless BLDC motor not only increases energy efficiency but also significantly extends the tool's service life by eliminating friction from carbon brushes. As a result, the tool is lighter (only 0.85 kg for the head alone) and more compact, with an overall length of just 111 mm. These small dimensions enable work in hard-to-reach areas where larger screwdrivers lack maneuvering space. Additionally, the use of XPT technology provides enhanced resistance to dust and moisture, which is invaluable when working outdoors or in dusty construction environments.

Working Comfort and Intelligent Support Functions

Ergonomics have been carefully designed for prolonged use. The elastomer-coated grip ensures a secure hold even under high torque, while the repositioned battery and control panel compared to older DTD172 models improve the tool's balance. A key convenience for installers is the LED ring lighting system. Unlike traditional side-mounted lamps, the ring around the chuck eliminates shadows cast by the bit or the operator's hand, providing perfect visibility of the work area from any angle. The light features 3-stage brightness adjustment and an intelligent automatic shut-off mode after one hour of inactivity, conserving battery energy.

The kit includes two 5.0 Ah Li-Ion batteries from the LXT 18V system and a charger, ensuring continuous operation without downtime for recharging. These batteries are compatible with the entire LXT tool ecosystem, increasing the versatility of the investment. For safety and convenience during bit installation, a mechanism allows one-handed bit changes: simply press the 1/4" hex chuck to insert or remove the bit without additional tools.

Applications and Operational Parameters

The tool excels in a wide range of applications: from sheet metal and carpentry assembly to installation work requiring tightening of high-strength screws (M5-M14). The 4-stage switching system allows clamping force to be adapted to the material type: the first gear offers a gentle 20 Nm torque for precise work with small screws, the second provides 50 Nm for general tasks, the third generates 170 Nm for heavier structural components, and the fourth gear delivers a maximum torque of approximately 180 Nm for the most demanding connections. Thus, one model replaces several tools of varying power.

The device is supplied in a Makpac type 2 system case, ensuring safe transport and easy workshop organization. Note the noise parameters: the sound pressure level is 97 dB(A), and the vibration level at maximum power is 12.9 m/s² (with tolerance K=1.5 m/s²); therefore, prolonged use requires hearing and hand protection. The manufacturer's warranty is standardly 3 years upon free product registration in the Makita service system.

To facilitate tool selection, note its capacity: machine screws from M4 to M8 are tightened most delicately at lower gears, while standard structural components M5-M16 require full power available in the fourth gear. High-strength screws fall within the M5-M14 range and also benefit from the high torque generated by the brushless motor at appropriately set impact frequency.
