Maxmech UIW 20-300 Cordless Impact Wrench 300 N

The Maxmech UIW 20-300 Cordless Impact Wrench is a powerful and essential tool for automotive work, heavy-duty fastening, and general construction. The “300 Nm” (Newton-meters) refers to its maximum torque, indicating its ability to loosen stubborn nuts and bolts and drive large fasteners with ease.

Key Features & Specifications (based on the model number and typical 20V 300Nm impact wrenches):

• Model: UIW 20-300
• Voltage: 20V Lithium-Ion Battery – Provides strong, consistent power for cordless operation, offering freedom of movement without the need for a power outlet. It’s part of the Maxmech 20V platform, allowing for battery sharing with other Maxmech 20V tools.
• Max Torque: 300 Nm (Newton-meters) – This is a significant amount of torque, making it suitable for:
  • Loosening rusted or over-tightened lug nuts on cars, SUVs, and light trucks.
  • Assembling and disassembling scaffolding or heavy equipment.
  • Driving large lag screws and bolts into wood or concrete (with appropriate anchors).
• Drive Size: Typically 1/2-inch square drive – This is the most common drive size for impact wrenches, compatible with a wide range of impact sockets.
• No-Load Speed (RPM): Varies, but usually in the range of 0-2300 RPM.
• Impact Rate (IPM – Impacts Per Minute): Also varies, but a 300Nm wrench would have a high impact rate, often 0-3300 IPM, which helps in breaking loose seized fasteners.
• Motor: Many modern cordless impact wrenches, especially at this torque level, feature brushless motors. A brushless motor provides higher efficiency, longer runtime, more power, and extended tool life compared to brushed motors. It’s a strong indicator of a quality tool.
• Variable Speed Trigger: Allows for precise control over the speed and power output.
• Forward/Reverse Switch: Conveniently located for easy switching between tightening and loosening.
• LED Work Light:
