Ingersoll Rand QP511LD Pistol Grip Air Production Drill | 0.25 HP | 5,100 RPM | 9.7 (In-lbs) Max Torque | Trigger-Start

Built for high-speed drilling where cycle time and precise tool control are important, the Ingersoll Rand QP511LD Pistol Grip Air Production Drill combines a 0.25 HP pneumatic motor with 5,100 RPM free speed and 9.7 in-lbs maximum torque. The high-speed configuration is suited to repetitive drilling with smaller cutting tools and compatible materials, while the trigger-start configuration gives the operator direct control over activation during positioning and drilling operations.

The Ingersoll Rand QP511LD is configured for production environments where rapid spindle rotation is preferred over the higher torque output available from slower QP drill models. Its pistol-grip configuration provides a familiar hand position for manual drilling at assembly stations, fabrication benches, and manufacturing work cells. With a 5,100 RPM free speed, the tool supports fast drilling cycles when the cutting tool diameter, workpiece material, and process requirements match the drill's speed and torque capabilities.

Type: Pistol Grip Air Production Drill | Model: QP511LD | Configuration: Pistol Grip | Motor Power: 0.25 HP | Free Speed: 5,100 RPM | Max Torque: 9.7 in-lbs | Start Type: Trigger-Start

Features:

• 0.25 HP pneumatic motor supplies rotational power for repetitive drilling in production and assembly environments.
• 5,100 RPM free speed supports fast drilling cycles with smaller cutting tools and compatible workpiece materials.
• 9.7 in-lbs maximum torque provides available turning force for applications matched to the tool's high-speed configuration.
• Trigger-start operation allows the operator to control tool activation directly while positioning and drilling.
• Pistol-grip configuration supports manual handling and controlled positioning at assembly stations and manufacturing work cells.
• High-speed design provides an alternative to slower, higher-torque QP drill models when rapid spindle rotation better matches the cutting process.
• Air-powered operation supports repeated drilling cycles at facilities equipped with 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 — performing repetitive drilling operations where high spindle speed helps reduce cycle time.
• Equipment manufacturing — drilling smaller holes in components and subassemblies at compressed-air production stations.
• Metal fabrication — preparing compatible sheet metal and fabricated parts for fasteners, hardware, and subsequent assembly operations.
• Automotive and transportation manufacturing — repetitive drilling of compatible components where the tool's speed and torque match the process requirements.
• Industrial maintenance and MRO — handling smaller-hole drilling tasks during machinery service, equipment installation, and component replacement.

FAQs:

• Q: What type of drilling work is the Ingersoll Rand QP511LD designed for?
  A: The QP511LD is intended for high-speed production drilling with smaller cutting tools and compatible workpiece materials. Suitable applications depend on the hole diameter, material, drill geometry, feed pressure, and manufacturer capacity guidance.
• Q: What does the 5,100 RPM rating mean?
  A: The 5,100 RPM specification is the tool's free speed, meaning its rotational speed without load. Actual drilling speed will vary according to the cutting tool, workpiece material, feed pressure, and available compressed-air supply.
• Q: How does the QP511LD compare with slower QP pneumatic drills?
  A: The QP511LD operates at a higher speed and provides lower maximum torque than slower QP drill configurations. It is intended for applications where rapid spindle rotation and shorter drilling cycles are preferred over increased turning force.
• Q: What does trigger-start mean on this production drill?
  A: Trigger-start means the operator activates and stops the pneumatic motor using the trigger control on the pistol-grip handle, allowing the tool to be positioned before rotation begins.
• Q: Does the 9.7 in-lbs maximum torque determine the largest hole this drill can produce?
  A: No. Maximum drilling capacity also depends on the workpiece material, cutting tool type and diameter, chuck capacity, feed conditions, and the manufacturer's application limits. Verify these factors before selecting tooling for the QP511LD.
