Built for high-torque drilling in restricted work areas, the Ingersoll Rand 6LR3A44 industrial angle drill delivers 0.51 HP, a controlled 400 RPM free speed, and up to 320.4 in-lbs of maximum torque for demanding industrial drilling applications. Its 90° chuck configuration provides excellent access inside machinery, structural assemblies, and equipment frames where conventional drills cannot operate, while the lever-start throttle offers precise speed control for accurate hole positioning and consistent drilling performance.
Designed for continuous-duty manufacturing and maintenance environments, the 6LR3A44 combines a durable pneumatic motor with a compact right-angle head to maximize accessibility while delivering exceptional torque. The low operating speed provides increased drilling force for larger drill bits and tougher materials, making this model well suited for fabrication, equipment maintenance, and production operations where torque takes priority over drilling speed.

Made in USA: 
Applications:
- Drilling large-diameter holes in machinery, heavy equipment, and structural components where high torque is required.
- Industrial maintenance and repair operations performed in confined workspaces.
- Production assembly applications requiring controlled, high-torque drilling performance.
- Metal fabrication involving thick materials, structural steel, and heavy-duty assemblies.
- Plant maintenance, MRO operations, and equipment installation where right-angle accessibility is essential.
FAQs:
- Q: Why does this drill operate at only 400 RPM?
A: The lower free speed allows the drill to generate substantially higher torque, making it better suited for larger drill bits and applications requiring greater drilling force. - Q: What advantage does the 90° chuck provide?
A: The right-angle configuration allows drilling in confined areas where straight or pistol-grip drills cannot fit, making it especially useful for machinery maintenance and heavy fabrication work. - Q: What is the benefit of the lever-start throttle?
A: The lever-start throttle provides responsive speed control, allowing operators to accurately start holes and maintain consistent drilling performance throughout the operation. - Q: Is this drill intended for continuous industrial use?
A: Yes. The manufacturer's catalog identifies the 6LR3A44 as an industrial pneumatic angle drill intended for manufacturing, fabrication, and maintenance applications.
