The combination of strength and control helps you work through stubborn fasteners without over-torquing nearby components.

• Maximum tightening torque: 515 ft-lbs (698 N.m); loosening torque up to 670 ft-lbs (910 N.m).
• Potentially speed up heavy-duty work by up to 30% versus standard models.

Speed, control, and versatility

The tool offers four precise torque presets—265, 295, 368, and 515 ft-lbs—plus a variable speed trigger, giving you options for a wide range of fasteners from small bolts to automotive repairs.

• 4-speed adjustable control lets you tailor power to the task.
• Variable speed trigger provides smooth starts and gradual power delivery.

Durability and runtime

An all-copper brushless motor delivers more stable power and can extend runtime by up to 50%, making longer sessions more manageable and reducing overheating risk during continuous use.

• All-copper brushless design improves efficiency and longevity.
• Extended runtime supports longer work sessions without frequent recharges.

Efficiency in tight spaces

Rapid directional change switches between forward and reverse in about 0.5 seconds with a single button, boosting workflow efficiency and reducing downtime when transitioning between steps.

Visibility and versatility

The integrated LED light uses a diffusion approach to illuminate the workspace clearly, even in dim garages. It remains compatible with a broad range of clamping, disassembly, and automotive tasks—covering a large majority of common applications.

• LED illumination helps you see fasteners and gaps clearly.
• Broad compatibility supports many common jobs in automotive and workshop settings.
