For repetitive drilling operations that need more turning force than high-speed pneumatic drills while maintaining productive spindle speed, the Ingersoll Rand QP301LD Pistol Grip Air Drill combines a 0.25 HP pneumatic motor with 3,000 RPM free speed and 15.9 in-lbs maximum torque. The trigger-start control allows the operator to position the cutting tool before activating the spindle, making this model a practical choice for production assembly, equipment manufacturing, fabrication, and other workstations where drilling cycles are performed repeatedly.
The Ingersoll Rand QP301LD uses a pistol-grip configuration for controlled manual drilling at production benches and assembly stations. Its 3,000 RPM speed-and-torque combination places the tool between faster, lower-torque QP drills and slower configurations intended for greater cutting loads. This balance allows buyers to select the drill according to the cutting-tool diameter, workpiece material, required cycle time, and torque demand of the process.
Type: Pistol Grip Air Drill | Model: QP301LD | Configuration: Pistol Grip | Motor Power: 0.25 HP | Free Speed: 3,000 RPM | Max Torque: 15.9 in-lbs | Start Type: Trigger-Start
Features:
- 0.25 HP pneumatic motor supplies rotational power for repetitive drilling and production assembly operations.
- 3,000 RPM free speed supports productive drilling cycles with compatible cutting tools and workpiece materials.
- 15.9 in-lbs maximum torque provides additional turning force compared with faster, lower-torque QP drill configurations.
- Trigger-start control allows the operator to position the cutting tool before activating the pneumatic motor.
- Pistol-grip configuration supports controlled manual handling at production stations, assembly benches, and fabrication work areas.
- Intermediate speed-and-torque setup provides an option between high-speed drilling and slower applications requiring greater available torque.
- Air-powered operation supports repeated production cycles when supplied with clean, regulated compressed air.
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 assembly — drilling components and subassemblies where moderate-to-high spindle speed and controlled manual handling support repetitive work.
- Equipment manufacturing — preparing parts for fasteners, hardware installation, and subsequent assembly processes.
- Metal fabrication — drilling compatible sheet metal, brackets, panels, and fabricated components with properly selected cutting tools.
- Automotive and transportation manufacturing — performing repeated drilling operations on compatible components and subassemblies.
- Industrial maintenance and MRO — handling drilling tasks during machinery service, equipment installation, and component replacement.
FAQs:
- Q: What type of drilling work suits the Ingersoll Rand QP301LD?
A: The QP301LD is suited to repetitive drilling where its 3,000 RPM speed and 15.9 in-lbs maximum torque match the cutting tool and workpiece. Application suitability also depends on hole diameter, material, chuck capacity, drill geometry, and feed conditions. - Q: How does the QP301LD compare with faster and slower QP drills?
A: The QP301LD provides an intermediate speed-and-torque configuration. Faster models offer more spindle speed with less torque, while slower models provide increased turning force for applications with greater cutting loads. - Q: What does trigger-start mean on this air drill?
A: Trigger-start means the operator activates and stops the pneumatic motor using a trigger on the pistol-grip handle. This allows the drill to be aligned with the workpiece before rotation begins. - Q: Does the 15.9 in-lbs maximum torque rating determine drilling capacity?
A: No. Drilling capacity also depends on the chuck, cutting-tool diameter and geometry, workpiece material, feed pressure, and manufacturer application limits. Review these factors together before selecting the tool for a specific drilling process. - Q: What should be checked before connecting the QP301LD to a compressed-air system?
A: Verify the manufacturer-specified operating pressure, airflow requirement, air inlet size, and minimum hose diameter. The compressor, regulator, fittings, and hose must maintain the required air supply while the drill is operating under load.
