Ingersoll Rand QP381D Pistol Grip Air Production Drill | 0.25 HP | 3,800 RPM | 13.3 (In-lbs) Max Torque | Trigger-Start

Built for production drilling where a balance of spindle speed and available torque matters, the Ingersoll Rand QP381D Pistol Grip Air Production Drill combines a 0.25 HP pneumatic motor with 3,800 RPM free speed and 13.3 in-lbs maximum torque. This mid-speed configuration supports repetitive drilling with compatible cutting tools while providing more turning force than higher-speed QP drill models. A trigger-start control lets the operator position the tool before activating the motor, supporting controlled drilling at assembly stations, fabrication benches, and manufacturing work cells.

The Ingersoll Rand QP381D uses a pistol-grip layout that provides a familiar hand position for manual production drilling. Its 3,800 RPM operating speed offers a practical middle ground between fast, lower-torque drilling and slower configurations intended for greater cutting loads. Actual drilling capability depends on the chuck, cutting-tool diameter, workpiece material, feed pressure, and available air supply, so each part of the setup should be matched to the production process.

Type: Pistol Grip Air Production Drill | Model: QP381D | Configuration: Pistol Grip | Motor Power: 0.25 HP | Free Speed: 3,800 RPM | Max Torque: 13.3 in-lbs | Start Type: Trigger-Start

Features:

• 0.25 HP pneumatic motor supplies rotational power for repetitive production drilling and assembly work.
• 3,800 RPM free speed supports efficient drilling cycles with compatible smaller-diameter cutting tools.
• 13.3 in-lbs maximum torque provides more available turning force than higher-speed, lower-torque drill configurations.
• Trigger-start control allows the operator to position the drill before activating spindle rotation.
• Pistol-grip configuration supports controlled manual handling at production stations, fabrication benches, and maintenance work areas.
• Mid-speed configuration offers a balance between rapid spindle rotation and the higher torque associated with slower QP drill models.
• Air-powered operation supports repeated drilling cycles when connected to a properly sized compressed-air system.

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 consistent cycle time and manual tool control are required.
• Equipment manufacturing — preparing parts for fasteners, hardware, and subsequent assembly operations at pneumatic workstations.
• Metal fabrication — drilling compatible sheet metal and fabricated components with tooling matched to the material and required hole size.
• Automotive and transportation manufacturing — performing repetitive drilling on compatible brackets, panels, 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 QP381D?
  A: The QP381D is suited to repetitive production and assembly drilling where 3,800 RPM and 13.3 in-lbs of maximum torque match the cutting tool and workpiece. Final suitability depends on hole diameter, material, chuck capacity, drill geometry, and feed conditions.
• Q: How does the QP381D compare with the QP511LD?
  A: The QP381D operates at 3,800 RPM and provides 13.3 in-lbs maximum torque. The QP511LD runs faster at 5,100 RPM but provides 9.7 in-lbs, so the QP381D offers more turning force at a lower spindle speed.
• Q: What does trigger-start mean?
  A: Trigger-start means the pneumatic motor is activated using a trigger on the pistol-grip handle. This allows the operator to align the cutting tool with the workpiece before rotation begins.
• Q: Does the maximum torque rating determine the largest hole the drill can make?
  A: No. Drilling capacity also depends on the chuck, cutting-tool diameter, workpiece material, cutting geometry, feed pressure, and manufacturer application limits. These factors should be reviewed together before selecting the drill.
• Q: What should be checked before connecting the QP381D to an air system?
  A: Verify the specified operating pressure, airflow, 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.
