For drilling and assembly operations that need more turning force than higher-speed pneumatic drill configurations, the Ingersoll Rand QP151D Pneumatic Air Drill combines a 0.25 HP air motor with 1,500 RPM free speed and a 30.1 in-lbs torque range. The trigger-start configuration gives the operator direct control over activation while positioning the tool on the workpiece, making the QP151D a practical choice for repetitive drilling tasks in production assembly, fabrication, equipment manufacturing, and industrial maintenance environments.
The Ingersoll Rand QP151D balances moderate rotational speed with increased available torque compared with faster models in the QP drill range. Its 1,500 RPM configuration is suited to applications where the drill, cutting tool, material, and hole size require more turning force while maintaining productive drilling speed. Pneumatic operation supports repeated use at compressed-air workstations, while the trigger-start control allows operators to start and stop the drill directly from the handle during drilling and compatible rotary-tool operations.
Type: Pneumatic Air Drill | Model: QP151D | Motor Power: 0.25 HP | Free Speed: 1,500 RPM | Torque Range: 30.1 in-lbs | Start Type: Trigger-Start
Features:
- 0.25 HP pneumatic motor supplies rotational power for repetitive drilling and compatible assembly operations.
- 1,500 RPM free speed balances productive drilling speed with greater available torque than faster configurations in the QP drill range.
- 30.1 in-lbs torque range supports drilling tasks that require additional turning force from a compact pneumatic tool.
- Trigger-start operation gives the user direct control over tool activation during positioning, drilling, and repeated production cycles.
- Air-powered configuration supports regular use at production stations and maintenance areas equipped with a properly sized compressed-air system.
- Speed and torque combination provides an option for applications where 2,000 RPM drill configurations do not provide the preferred balance of rotational speed and available torque.
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 holes in components and subassemblies during repetitive manufacturing processes.
- Metal fabrication — preparing compatible workpieces for fasteners, hardware installation, and subsequent assembly operations.
- Equipment manufacturing — supporting repeated drilling tasks at workstations supplied by centralized compressed-air systems.
- Industrial maintenance and MRO — performing drilling operations during machinery repair, equipment installation, and component replacement.
- General shop work — handling drilling and compatible rotary-tool tasks where the 1,500 RPM speed and 30.1 in-lbs torque range match the tooling and workpiece requirements.
FAQs:
- Q: What type of work is the Ingersoll Rand QP151D designed for?
A: The QP151D is a pneumatic drill for repetitive drilling and compatible rotary-tool operations in production assembly, fabrication, equipment manufacturing, maintenance, and general shop environments. - Q: How does the QP151D differ from the QP201D?
A: The QP151D operates at 1,500 RPM with a 30.1 in-lbs torque range, while the QP201D operates at 2,000 RPM with a 24.8 in-lbs torque range. The QP151D provides a slower-speed, higher-torque option for applications requiring additional turning force. - Q: What does trigger-start mean on the QP151D?
A: Trigger-start means the operator activates and stops the pneumatic motor using the tool's trigger control. This allows the drill to be positioned on the workpiece before rotation begins. - Q: Does the 30.1 in-lbs torque range determine the maximum hole size?
A: No. Suitable hole size also depends on the workpiece material, drill bit type and diameter, cutting conditions, feed pressure, and manufacturer application guidance. Compare these factors with the QP151D specifications before selecting the tool. - Q: What should be verified before connecting this drill to a compressed-air system?
A: Confirm the manufacturer's 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.
