Built for repetitive production drilling, assembly work, and fabrication, the Ingersoll Rand 5AJST4 Pistol Grip Air Drill combines a fast 4,500 RPM free speed with 20 in-lbs (2.3 Nm) of maximum working torque. This higher-speed configuration is suited to compatible small-hole drilling where rapid bit rotation is preferred, while the pistol-grip layout provides straightforward handheld control at production benches and maintenance workstations.
The 1/4" (6 mm) bit holder capacity accommodates compatible smaller-diameter drilling tooling, while 17 CFM (480 L/min) air consumption provides an important reference when matching the tool to a facility's compressed-air supply. At 2.0 lb (0.9 kg), the 5AJST4 keeps tool weight manageable for repeated handheld drilling in manufacturing, fabrication, and equipment service environments.

Features:
- 4,500 RPM free speed supports rapid drilling cycles in compatible production and assembly applications.
- 20 in-lbs (2.3 Nm) maximum working torque provides controlled output for smaller-hole drilling tasks.
- 1/4" (6 mm) bit holder capacity accepts compatible drilling tooling within the specified size range.
- Trigger-start actuation places tool control directly at the pistol-grip handle.
- Non-reversible configuration provides straightforward forward drilling operation.
- 6.8" (173 mm) length with chuck provides a compact profile for maneuvering around workpieces and production fixtures.
- 2.0 lb (0.9 kg) weight with chuck limits unnecessary bulk during repetitive handheld drilling.
- 0.8" (21 mm) side-to-center distance helps position the drill close to workpiece edges and adjacent surfaces.
Tech Tip: To increase tool performance, extend tool life and lessen repair costs use it with a Filter-Regulator-Lubricator (FRLs)
Made in USA: 
Applications:
- Production and assembly stations performing repetitive small-hole drilling.
- Metal fabrication work using compatible 1/4" drilling tooling.
- Manufacturing operations where higher spindle speed supports efficient drilling cycles.
- Industrial maintenance and MRO work involving fixtures, machinery, and equipment components.
- Professional workshops equipped with a compressed-air system capable of supplying the specified airflow.
FAQs:
- Q: What is the maximum working torque of the Ingersoll Rand 5AJST4?
A: The 5AJST4 provides 20 in-lbs (2.3 Nm) of maximum working torque. Its 4,500 RPM free speed makes this model more focused on faster rotation than the slower, higher-torque drills listed in the same 5 Series range. - Q: What size tooling can the 5AJST4 accept?
A: The manufacturer table specifies a maximum bit holder capacity of 1/4" (6 mm). Select tooling that fits the holder correctly and is appropriate for the workpiece material and drilling operation. - Q: How much compressed air does the 5AJST4 consume?
A: Air consumption is specified at 17 CFM (480 L/min). The compressed-air system should be capable of maintaining the required airflow at the tool during operation. - Q: Is the Ingersoll Rand 5AJST4 reversible?
A: No. The 5AJST4 belongs to Ingersoll Rand's non-reversible 5 Series pistol-grip drill range and is configured for forward drilling operation. - Q: When should I choose a higher-speed air drill like the 5AJST4?
A: A higher-speed drill can be useful for compatible smaller-hole drilling applications where rapid bit rotation is more important than the higher torque provided by slower drill models. Final tool and bit selection should account for hole diameter, tooling, and workpiece material.
