- Maximum torque of 312 Nm (230 ft-lb) — delivers the raw power needed to break loose heavily corroded or over-torqued fasteners in automotive and industrial environments, eliminating the need for manual breaker bars or larger, heavier tools.
- 7,000 RPM free speed with 1/2" square drive — the high rotational speed combined with the industry-standard half-inch drive ensures rapid socket engagement and fast cycle times, significantly reducing labour hours on repetitive fastening tasks.
- Compact 180 mm body length and 2.15 kg net weight — the short, ergonomic housing allows access to confined engine bays, wheel arches, and machinery cavities where bulkier impact wrenches cannot reach, while the low weight reduces operator fatigue during extended use.
- 90 PSI maximum operating pressure with 1/4" air inlet — the tool operates efficiently within the output range of most workshop compressors, and the standard quarter-inch BSP air inlet accepts common quick-connect fittings including the supplied Japanese connector for immediate plug-and-play setup.
- 5 CFM (141 L/min) average air consumption — the optimised pneumatic motor draws only 5 CFM, making it compatible with mid-range compressors and reducing energy costs in high-cycle workshop environments without sacrificing torque delivery.
- 14 mm bolt capacity with CE-certified machine safety — rated for bolts up to 14 mm in diameter and independently verified to CE Machine Test standards, the AW313 meets the safety and performance requirements for professional use across the EU, UAE, and international markets. The package includes the impact wrench, a guide book, a wrench, and a Japanese connector, providing everything needed for immediate deployment.
General Purchase & Comparison Queries
What makes the ID AW313 different from other 1/2" pneumatic impact wrenches?
The ID AW313 combines a 312 Nm maximum torque output with a compact 180 mm body length and a lightweight 2.15 kg frame — a balance that many comparable tools sacrifice. Its 7,000 RPM free speed and low 5 CFM air consumption mean it performs at a professional level without requiring a large industrial compressor, making it a cost-effective choice for both workshop and field use.
Is the AW313 suitable for both professional workshops and DIY use?
Yes. The AW313 pneumatic impact wrench is designed for professional-grade performance but is equally well-suited to serious DIY users. Its CE Machine Test certification, standard 1/2" square drive, and compatibility with common workshop compressors (operating at up to 90 PSI / 6.3 kg/cm²) make it accessible and reliable for tyre changes, engine work, and general mechanical repairs at home or in a commercial garage.
What is included in the box, and is it ready to use out of the package?
The package includes the AW313 impact wrench machine, a guide book, a wrench, and a Japanese connector for the air inlet. The Japanese connector allows direct connection to standard air hose quick-release fittings, so the tool is ready for immediate use once connected to a compatible compressor. Impact sockets are sold separately and should always be used in place of standard chrome sockets.
Product-Specific and Usage Queries
What compressor specifications do I need to run the AW313 effectively?
The ID AW313 requires a compressor capable of delivering at least 5 CFM (141 L/min) at a working pressure of up to 90 PSI (6.3 kg/cm²). The air inlet is a standard 1/4" BSP fitting. For continuous use in a busy workshop, a compressor with a tank of 50 litres or more is recommended to maintain consistent pressure and prevent the tool from losing torque mid-task.
What is the maximum bolt size the AW313 can handle?
The AW313 is rated for a bolt capacity of up to 14 mm in diameter. With a maximum torque of 312 Nm (230 ft-lb), it is well-suited for wheel lug nuts, suspension bolts, engine mounts, and structural fasteners commonly found in automotive and light industrial applications. For fasteners larger than 14 mm or requiring torques beyond 312 Nm, a higher-capacity impact wrench would be recommended.
Can the AW313 be used for both tightening and loosening bolts?
Yes, the ID AW313 pneumatic impact wrench is designed for both tightening and loosening operations. The forward/reverse mechanism allows the operator to switch direction as needed. When tightening, it is important to use a torque stick or torque wrench for final verification on safety-critical fasteners such as wheel lug nuts, as impact wrenches deliver impact-based torque that can vary slightly with air pressure fluctuations.
Problem/Solution-Oriented Queries
The wrench is not delivering full torque — what should I check?
If the AW313 is underperforming, the most common causes are insufficient air supply or a restricted air line. First, verify that your compressor is delivering at least 90 PSI at the tool inlet and that the air hose has an internal diameter adequate for 5 CFM (141 L/min) flow. Check that the Japanese connector and air inlet are fully seated and free of debris. Also ensure the tool is lubricated — a few drops of pneumatic tool oil into the air inlet before each use will maintain the internal hammer mechanism and preserve maximum torque output.
What should I do if the impact mechanism feels weak or the tool vibrates excessively?
Excessive vibration or a weak impact mechanism in the AW313 is typically caused by worn internal hammer and anvil components, or by operating the tool without adequate lubrication over time. Regular maintenance — including pneumatic tool oil application at the air inlet before each session — significantly extends the life of the hammer mechanism. If the issue persists after lubrication and pressure checks, the internal hammer assembly may require inspection or replacement. Contact your supplier for spare parts support.
