1/2" Drive Air Impact Wrench 625nm SATA ST01111

The SATA ST01111 is a pneumatic (air-powered) impact wrench with a 1/2" drive that delivers up to 625 Nm of torque. It’s designed for loosening and tightening heavy bolts and fasteners, making it suitable for automotive work, truck maintenance, and other heavy-duty assembly tasks.

Key specs include a 1/2" drive and an impact torque of up to 625 Nm. It’s a SATA-branded air tool built for professional use. For compatible sockets, you’ll want standard 1/2" drive impact sockets.

Connect the tool to a suitable air compressor with a clean, dry air supply. Use a properly rated air hose and regulator, attach a 1/2" drive impact socket, and ensure the air inlet is secured. Lubricate the tool with pneumatic oil as recommended by SATA, then test operation at a low speed before applying full torque.

Use the forward/reverse rocker or switch to select the turning direction. Press the trigger to engage the tool and deliver torque in short bursts for controlled loosening or tightening. Start at low throttle and increase as needed to avoid bolt or socket damage.

Wear eye and hearing protection, secure your workpiece, keep hands away from moving parts, and disconnect the air supply before changing sockets or performing maintenance. Use a properly rated air supply and check hoses for leaks regularly.

Regularly lubricate the tool with pneumatic oil, drain moisture from the air line, and clean any dust from the exterior. Periodically inspect hoses, fittings, and the drive for wear, and store the tool in a dry place when not in use.

You'll likely want a set of 1/2" drive impact sockets, an inline oiler or automatic oiling system, a quality air hose, a notched or impact-rated socket rail, and a case or bag for transport and storage.

It's well-suited for automotive work (lug nuts, suspension bolts), heavy equipment maintenance, machinery assembly, and any job requiring a high-torque, durable 1/2" drive tool where air-powered impact is advantageous.

If you’re evaluating options within SATA’s 1/2" lineup on Fepy, you can compare this model (ST01111, 625 Nm) against models such as SATA ST01112 (typically higher torque, e.g., around 700 Nm) and SATA ST01110 (lower torque, around 550 Nm) to match your torque needs. Product pages for these alternatives can be viewed here: https://fepy.com/product/sata-st01112-1-2-drive-air-impact-wrench-700nm and https://fepy.com/product/sata-st01110-1-2-drive-air-impact-wrench-550nm

Yes. Its 625 Nm torque and robust construction make it appropriate for automotive repair, heavy equipment maintenance, and industrial applications where high torques are required and a durable air-powered tool is preferred.

If you need to return this item, our standard policy allows returns within 30 days (or as specified on the product page) in unused condition and original packaging. Be sure to follow the return instructions provided on Fepy for eligibility and process.

Compare torque ratings, weight, and price to fit your job. If you need maximum torque, models with higher Nm like the 700 Nm alternative may be preferable; for lighter-duty needs, a model with around 550–600 Nm might be more cost-effective. Review the respective product pages to assess grip, balance, and ergonomics before deciding.

First, check the air supply pressure and ensure it’s within the tool’s recommended range. Inspect for air leaks, verify the socket is correctly seated, and confirm the reverse/forward switch is functioning properly. If lubrication is due, apply the recommended amount and test again. If problems persist, consult the product’s manual or provide a service check.
