Ingersoll Rand 7LN3A44 Non-Reversible Pneumatic Angle Drill | 0.75 HP | 600 RPM | 1/2" Chuck Capacity

When drilling operations require access around machinery frames, fixtures, or other obstructions, the Ingersoll Rand 7LN3A44 Non-Reversible Pneumatic Angle Drill combines a 90-degree chuck configuration with controlled, low-speed drilling performance. Part of the 7 Series, this lever-start air drill delivers 0.75 HP, a 600 RPM free speed, and 255 in-lbs (28.1 Nm) of maximum working torque for drilling applications that benefit from greater turning force at lower speeds. Its 1/2" (13 mm) chuck capacity accommodates appropriately sized drill bit shanks, while the right-angle head positions the chuck perpendicular to the main tool body. This arrangement helps operators reach drilling locations where a conventional straight or pistol-grip drill may be difficult to position.

The Ingersoll Rand 7LN3A44 features double-row ball bearings that support concentric drilling, helping maintain alignment during hole-making operations. Its modular construction allows easier access to service components, while variable-speed lever control enables operators to begin drilling gradually before increasing speed. With an 11.1" overall length, 4.1" angle head height, and 0.7" side-to-center distance (the distance from the spindle centerline to the side of the angle head), the drill provides useful dimensional information for planning access around fixtures and workpieces. Weighing 4.2 lbs, it operates through a 1/4" NPT air inlet with a specified 26 CFM air consumption. Its non-reversible operation makes it suitable for forward-drilling tasks in manufacturing, assembly, fabrication, and industrial maintenance environments.

Features:

• 90-degree angle head positions the chuck perpendicular to the tool body, helping operators drill around obstructions and within restricted working areas.
• 0.75 HP pneumatic motor provides power for production drilling and industrial assembly operations.
• 600 RPM free speed and 255 in-lbs maximum working torque support lower-speed drilling applications requiring controlled rotation and substantial turning force.
• 1/2" chuck capacity accommodates drill bit shanks within the specified chuck size.
• Double-row ball bearings support precise, concentric hole-making by helping maintain spindle alignment.
• Lever-start actuation with variable-speed control allows gradual drill starting and adjustment of rotational speed during operation.
• Modular construction facilitates component interchangeability and simplifies maintenance procedures.
• Non-reversible configuration provides forward drilling operation for applications that do not require powered reverse rotation.

Tech Tip: To increase tool performance, extend tool life, and lessen repair costs, use it with a Filter-Regulator-Lubricator (FRLs)

Applications:

• Industrial manufacturing and production assembly – Drilling holes in components positioned within assembly fixtures or equipment structures where straight drill access is restricted.
• Metal fabrication – Performing controlled drilling on metal parts and fabricated assemblies requiring a right-angle approach to the workpiece.
• Machinery maintenance and MRO – Accessing drilling locations near machinery frames, mounting brackets, and surrounding components during repair work.
• Industrial equipment assembly – Drilling holes in structural components, brackets, and mounting locations where the 90-degree head improves tool positioning.
• Toolrooms and fixture construction – Producing holes in workholding fixtures and assembled components where low-speed operation and consistent spindle alignment are important.

FAQs:

• Q: What makes the Ingersoll Rand 7LN3A44 suitable for drilling in restricted spaces?
  A: Its 90-degree chuck arrangement lets the drill bit approach the workpiece perpendicular to the main tool body. The 4.1" angle head height and 0.7" side-to-center distance help buyers evaluate clearance around fixtures and machinery. Check the complete tool dimensions and installed drill bit length before selecting it for a confined location.
• Q: Can the Ingersoll Rand 7LN3A44 run in reverse?
  A: No. The 7LN3A44 is a non-reversible pneumatic angle drill intended for forward rotation. If powered reverse operation is required for your application, select a model specifically equipped with that capability.
• Q: What air supply does the 7LN3A44 require?
  A: Ingersoll Rand specifies 26 CFM (736 L/min) air consumption and a 1/4" NPT air inlet. The compressor and air distribution system must provide adequate airflow and the operating pressure specified in the tool instructions. Account for pressure losses through hoses, fittings, and air preparation equipment when planning the installation.
• Q: What is the difference between the 7LN3A44 and the 7LM3A43 angle drills?
  A: The 7LN3A44 operates at 600 RPM with 255 in-lbs of maximum working torque and a 1/2" chuck capacity. The 7LM3A43 operates at 900 RPM with 170 in-lbs of maximum working torque and a 3/8" chuck capacity. The 7LN3A44 is the lower-speed, higher-torque option with the larger chuck.
• Q: How does variable-speed lever control work on this non-reversible drill?
  A: The lever-start throttle allows the operator to vary drilling speed, including starting at a lower rotational speed for better control when positioning the bit. Variable-speed operation does not provide reverse rotation; the 7LN3A44 remains a forward-only drill.
