Built for drilling in restricted work areas where conventional drills cannot reach, the Ingersoll Rand 5LK1B1 industrial angle drill delivers 0.40 HP, a fast 3,000 RPM free speed, and up to 31 in-lbs of maximum torque for efficient drilling in light to medium-duty industrial applications. Its 45° small angle head provides improved access around obstructions while maintaining a more direct drilling approach than a traditional 90-degree angle drill, and the lever-start throttle offers responsive speed control for accurate hole placement.
Designed for continuous industrial service, the 5LK1B1 combines a compact pneumatic motor with a low-profile angled head to improve maneuverability in confined spaces. The higher operating speed makes it well suited for production drilling where faster material penetration is desired, while the lightweight angle-head configuration helps technicians work comfortably in machinery, fabrication assemblies, and maintenance applications with limited clearance.

FAQs:
- Q: What advantage does the 45° small angle head provide?
A: The 45° head offers improved access around obstructions while maintaining a drilling angle that is more direct than a 90° configuration, making it useful for applications with moderate clearance restrictions. - Q: Why does this drill operate at 3,000 RPM?
A: The higher free speed allows faster drilling in applications where quicker material penetration is preferred while maintaining controlled pneumatic performance. - Q: What is the benefit of the lever-start throttle?
A: The lever-start throttle provides responsive speed control, allowing operators to start holes accurately and maintain consistent drilling control. - Q: Is this drill suitable for continuous industrial operation?
A: Yes. The manufacturer's catalog identifies the 5LK1B1 as an industrial pneumatic angle drill intended for production and maintenance environments.
