Description
The ST‑5552 is a 3/8″ square‑drive pneumatic air ratchet wrench from the brand Sumake (also marketed as “Sonic”) designed for moderate torque fastening and loosening applications. It delivers a maximum torque of 61 Nm (45 ft‑lb) at a free speed of 150 rpm. The tool has a compact length of approximately 260 mm (10‑1/4″), uses a ¼″ air inlet and recommended 3/8″ hose. It is designed for workshop or production environments where controlled ratcheting rather than high‐speed impact is required.
Features
:- 3/8″ square drive, suitable for standard 3/8″ sockets.
- Maximum torque : 61 Nm (45 ft‑lb) - enabling removal and tightening of moderate sized bolts.
- Free speed : 150 rpm - offering controlled ratcheting (not a high‑rpm impact gun) for precision.
- Air consumption : 4.0 cfm (113 L/min) and recommended working air pressure: about 6.5 kg/cm² (~90 psi).
- Overall length : approx. 260 mm (10‑1/4″) for good reach without being overly long.
- Net weight : about 1.2 kg (2.7 lb) - reasonably lightweight for a ratchet wrench in this class.
- Standard air inlet: ¼″ (PT), accepted 3/8″ air hose ID to minimize pressure drop.
- Integrated ratchet mechanism designed for continuous use; likely with ergonomic handle and durable housing.
Applications
:- Automotive workshop use: removal and tightening of bolts/nuts in engine compartments, chassis, suspension, exhaust systems where a 3/8″ drive ratchet is appropriate.
- Vehicle body‐shop or service bays: tasks such as fastener removal in tight spaces, panels, brackets, harness mounts.
- General industrial maintenance: fastening or loosening moderate sized bolts on machines, conveyors, support frames where you need a ratchet tool rather than heavy‑impact.
- Production or assembly lines: where repeated fasteners are used, and a ratchet with moderate torque provides consistent, controlled fastening.
- Equipment servicing or MRO (maintenance, repair, overhaul): for medium‐duty bolting operations where access may be limited.
- Workshops handling light to medium sized equipment such as air compressors, pumps, gearboxes, where a 61 Nm ratchet is adequate.
