Makita DTD173Z (w/o Battery)

The Makita DTD173Z and DTD172Z are both powerful, 18V brushless impact drivers designed for demanding fastening tasks. A notable distinction lies in their torque capabilities: the DTD173Z offers a variable range stretching from 20 to 180 Nm, providing greater finesse for lighter applications. Conversely, the DTD172Z is specified with a fixed maximum torque output of 180 Nm, suggesting a focus purely on high-power fastening. Regarding function, the DTD172Z is explicitly categorized as both an Impact Driver and Screwdriver, whereas the DTD173Z focuses solely on the impact driver designation, although both support screw function. If you require the flexibility of lower torque settings for delicate work, the DTD173Z holds an advantage, but the DTD172Z remains a robust choice centered around its maximum power.
