Built for production drilling, assembly work, and industrial maintenance, the Ingersoll Rand 6AKST4 Pistol Grip Air Drill delivers 45.1 in-lbs (5.1 Nm) of maximum working torque with a 3,100 RPM free speed. This speed-and-torque combination supports repetitive drilling where fast cycle times and controlled material removal are important, while the compact pistol-grip configuration provides straightforward handling around workpieces and fixtures.
The 1/4" (6 mm) bit holder capacity accommodates compatible smaller-diameter drilling tooling, while 20 CFM (560 L/min) air consumption helps buyers plan the required compressed-air supply. At only 2.2 lb (1.0 kg), the 6AKST4 keeps tool weight manageable during repetitive drilling in manufacturing, fabrication, and maintenance environments.

Working Torque: 45.1 in-lbs (5.1 Nm) | Free Speed: 3,100 RPM | Bit Holder Capacity: 1/4" (6 mm) | Air Consumption: 20 CFM (560 L/min) | Weight with Chuck: 2.2 lb (1.0 kg) | Length with Chuck: 7.0" (178 mm) | Side-to-Center Distance: 0.8" (21 mm)
Features:
- 3,100 RPM free speed supports efficient drilling cycles in repetitive production and assembly operations.
- 45.1 in-lbs (5.1 Nm) maximum working torque provides useful turning force for compatible drilling tasks.
- 1/4" (6 mm) bit holder capacity accommodates compatible drilling tooling within the specified size range.
- Trigger-start configuration puts tool actuation directly at the pistol-grip handle.
- 7.0" (178 mm) length with chuck provides a compact overall profile for working around fixtures and components.
- 2.2 lb (1.0 kg) weight with chuck helps reduce unnecessary tool bulk during repetitive handheld drilling.
- 0.8" (21 mm) side-to-center distance allows drilling relatively 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.

FAQs:
- Q: How much torque does the Ingersoll Rand 6AKST4 provide?
A: The 6AKST4 is rated for 45.1 in-lbs (5.1 Nm) of maximum working torque. Its combination of torque and 3,100 RPM free speed makes it suited to compatible production and assembly drilling operations. - Q: What size tooling does the 6AKST4 accept?
A: The specification table lists a maximum bit holder capacity of 1/4" (6 mm). Tooling should fit the holder correctly and be appropriate for the material and drilling operation. - Q: How much compressed air does the 6AKST4 consume?
A: The manufacturer table specifies 20 CFM (560 L/min). The facility air system should be capable of supplying adequate airflow at the tool during operation. - Q: Is the 6AKST4 suitable for repetitive production drilling?
A: Yes. Its pistol-grip configuration, 3,100 RPM speed, compact dimensions, and 2.2 lb weight make it applicable to compatible repetitive drilling tasks at production and assembly stations. - Q: How does the 6AKST4 compare with the 6AJJST4?
A: The 6AKST4 trades some rotational speed for additional torque. The 6AKST4 is rated at 3,100 RPM and 45.1 in-lbs, while the 6AJJST4 is listed at 3,950 RPM and 35 in-lbs; both have a 1/4" bit holder capacity.
