Impact wrench 1/2" 12Vmax LI-ION CXT 2.0 Ah 140NM TW141DSAE

Power and Precision in a Compact Housing

Powered by the 12Vmax CXT battery system, this tool delivers an impact torque of up to 140 Nm (as per the model name) or even 145 Nm (according to manufacturer data), making it effective for loosening and tightening bolts with diameters up to 12.7 mm. Equipped with a 1/2" anvil, the tool is ideal for assembly tasks requiring greater torque than standard 3/8" impact wrenches, yet where heavier 18V or 24V machines cannot be used.

The tool weighs only 1.1–1.2 kg (without battery), significantly reducing operator fatigue during overhead work or in hard-to-reach areas. Its ergonomic handle ensures a secure grip even under high torque, while its compact dimensions allow free movement in tight engine compartments or around suspension components.

Performance and Working Comfort

The wrench features a high no-load speed of up to 2600 rpm, enabling fast task completion. However, it is important to note the specific nature of impact tool operation – generated noise can reach 104 dB(A) (sound power level), and sound pressure level 93 dB(A), so hearing protection is recommended.

Vibration transmitted to the hand during tightening of maximum-capacity screws is approximately 7.5 m/s². This value is typical for this class of tools, but thanks to its balanced construction and handle damping, the impact on the user's nervous system is minimized.

Applications and Compatibility

The tool is designed for a wide range of applications, including assembly and disassembly of car wheels (when used with appropriate sockets), carpentry and joinery tasks requiring strong tightening of bolted joints, mechanical installations in light industry and construction, as well as bicycle servicing and gardening work on larger machinery. Thanks to compatibility with the CXT battery series, users can utilize this wrench within the MAKITA 12Vmax tool ecosystem, eliminating the need for multiple different power systems. The kit includes a 2.0 Ah battery, providing sufficient runtime for typical service tasks without the need for constant battery swapping.

The TW141DSAE wrench combines parameters characteristic of professional tools: torque up to 145 Nm, no-load speed of 0–2600 rpm, and a low weight of approximately 1.2 kg. Noise level during operation does not exceed 93 dB(A) (sound pressure level), and vibration during tightening is 7.5 m/s². These technical specifications make the tool ready for intensive use in workshops or on construction sites.
