1/2" DRIVE MINI AIR IMPACT - Horizon Tool, Inc

The Horizon Tool, Inc. NC-4630Q 1/2" Drive Mini Air Impact (part 208565) is engineered for professional technicians who require substantial 1/2" drive power in the most restricted work environments. Its ultra-compact design, combined with a robust jumbo-hammer mechanism, establishes this as a dependable tool for daily use across demanding automotive and light industrial applications.

Key Features

• High Torque in Confined Spaces: Delivers up to 450 ft-lb max reverse torque and 200–350 ft-lb forward torque, providing the necessary power for rusted or high-torque fasteners in limited access areas.
• Ultra-Compact Design: With an overall length of approximately 3-13/16", this impact wrench offers exceptional maneuverability around frames, suspension components, wheel wells, and crowded engine bays where standard 1/2" impacts are often too large.
• Precise, One-Handed Control: Features a thumb-operated forward/reverse switch with integrated power regulation and a variable speed trigger, allowing for quick direction changes and controlled rundown to prevent over-torque.
• Reduced Operator Fatigue: An ergonomic rubber grip and a low-vibration design (2.8 m/s²) contribute to enhanced comfort during extended use at the tire machine, alignment rack, or undercar bay.
• Cleaner Work Environment: The bottom handle exhaust system efficiently directs air away from the work surface and operator, helping to maintain clear visibility and comfort.

Applications

Designed for professional automotive repair on passenger cars, light trucks, and SUVs, the NC-4630Q excels in tasks such as tire and wheel service, suspension work, brake and undercar repairs, engine component removal, and other fastener jobs with limited access. It is also well-suited for light industrial assembly, agricultural equipment maintenance, and general fleet service where a compact, dependable 1/2" pneumatic impact is required.
