Impact Wrench Makita TW004GZ 1/2 inch 3200 RPM 630 N⋅m Green

The Makita TW004GZ 1/2" impact wrench delivers up to 630 N⋅m of maximum torque and an idle speed of 3200 RPM in a compact, battery-powered design. With overall dimensions of 86 mm (W) × 144 mm (D) × 248 mm (H) and a weight of 1.9 kg, this green impact wrench balances power and portability for use where corded tools are impractical. The tool is intended for fastening and loosening high-torque fasteners in professional and home workshop environments while offering simple handling due to its compact footprint.

Advantages

The cordless configuration enables operation without a power cable, increasing mobility on job sites and in vehicles. High maximum torque provides sufficient force for demanding fastening tasks, and the 3200 RPM idle speed helps achieve quick rotations when starting or aligning fasteners. The compact dimensions and moderate weight reduce operator fatigue during extended use, while the robust construction typical of the manufacturer supports durability under regular mechanical work.

Suitable for

• Automotive wheel and suspension maintenance
• Construction and assembly of steel structures
• Equipment and machinery maintenance
• Workshop fastening and removal of heavy bolts and nuts
• Mobile repair work where mains power is unavailable

How to use

Fit a compatible 1/2" socket to the anvil and secure it before applying torque. Select the required speed and direction settings if the tool offers selectable modes, then position the socket on the fastener and depress the trigger to operate. Use short bursts when initially breaking loose tight or corroded bolts to avoid uncontrolled spinning; for tightening, engage slowly and monitor torque by feel or with a torque monitoring accessory. Observe battery charge level and swap or recharge batteries as needed to maintain consistent performance.

Recommendations

Use appropriate personal protective equipment, including eye protection and gloves. Match socket sizes precisely to fasteners to prevent rounding. For repetitive high-torque applications, allow the tool to cool periodically and use batteries specified by the manufacturer to ensure safe operation and maintain rated performance.
