The Makita DTW300 Brushless LXT 1/2in Impact Wrench is ideal for automotive, installation and fabrication trades. Combining extended run time and speed control for unmatched fastening performance. It is powered by a Makita-built brushless motor for longer run time. Precise fastening control is achieved through the 4-speed power selection switch, which accounts for a wide range of applications. Three forward and three reverse rotation auto-stop modes offer increased efficiency when the fastener is adequately loosened. The full-speed mode function reduces the trigger pull to reach full speed. The DTW300 features Makita's Extreme Protection Technology (XPT), a protective seal inside the tool. It is designed to improve a tool's operation in harsh conditions by channelling water and dust from key internal components.
