Description
The ST-4468 is a 1/4″ hex-shank, pistol-type air impact screwdriver built around a double-hammer (twin-hammer) impact mechanism, delivering high speed and compact size, designed for precision assembly and fastening work in industrial or production-line environments. According to the manufacturer spec sheet, it has a free speed of 13,000 RPM and a maximum torque of approximately 35 Nm (about 31 in-lbs / 35 kg-cm) under recommended air supply conditions.

Features

 :
  • Double-hammer mechanism: This arrangement provides rapid impact action (two hammer strikes per cycle) enabling higher torque output and improved durability compared to simpler clutch or single-hammer types. 
  • High free speed: 13,000 RPM no-load speed allows fast driving of screws/bolts. 
  • Compact & lightweight design: Overall length about 140 mm (5.5″) and net weight ~0.88 kg (1.9 lbs) making it easier to handle and manoeuvre in confined spaces. 
  • Standard 1/4″ hex shank: Accepts 1/4″ bits or sockets (bolt size capacity ~5-6 mm / 5/32″) for flexibility in assembly tasks. 
  • Air inlet and hose size: 1/4″ PT or NPT air inlet, recommended air hose 3/8″ I.D. (≈9.5 mm) for adequate supply. Suggested working air pressure ~6.3 kg/cm² (≈90 psi). 
  • Moderate air consumption: ~7 cfm (≈198 L/min) under typical conditions. 
  • Reversible operation: (Assuming standard impact screwdriver features) forward and reverse for driving and removal of fasteners.
  • Durable construction: Designed for high-cycle use in production environments; the twin hammer mechanism enhances life and reliability.

Applications

 :
  • Production lines where many small-sized bolts/screws (≈ 5-6 mm / 5/32″) must be driven quickly and reliably. According to the spec it has a capacity bolt size of 5/32″ (5-6 mm) and a max torque around 31 in-lb (35 kg-cm).
  • Assembly of mechanical sub-components: e.g., brackets, housings, machine panels, where a fast, impact-type screwdriver can speed throughput compared to standard screwdrivers.
  • Maintenance, repair & overhaul (MRO) tasks: loosening or tightening smaller fasteners in equipment, machinery, vehicle components where access may be somewhat restricted but speed is needed.
  • Workshops and light-industrial settings where a compact, pistol-style impact screwdriver is required; the net weight is about 0.88 kg (1.9 lb) and length approx. 140-143 mm (5-½″) giving good manoeuvrability.
  • Environments requiring repetitive fastening where operator fatigue must be minimised: the high no-load speed (13,000 RPM) allows fast cycle times and the double-hammer mechanism delivers consistent torque pulses.
  • Smaller or medium-size bolt applications rather than heavy truck or heavy industrial bolts; the specification shows it is designed for smaller bolts (5-6 mm) rather than large high-torque joints.
