Ingersoll Rand 728LA2 Pneumatic Pistol Grip Maintenance Drill | 0.50 HP | 2,100 RPM | 3/8" Chuck Capacity

When routine equipment repairs and fabrication work call for more turning force than a high-speed drill provides, the Ingersoll Rand 728LA2 Pneumatic Pistol Grip Maintenance Drill delivers a practical balance of drilling speed and torque. Part of the 728 Series, this air-powered drill operates at 2,100 RPM free speed (rotational speed without drilling resistance) and develops 54 in-lbs (6.1 Nm) of maximum working torque. Its 3/8" (10 mm) chuck capacity accommodates appropriately sized drill bit shanks for general maintenance, repair, and assembly tasks. Compared with the faster 728JA1 model, the 728LA2 provides greater working torque at a lower rotational speed, making it a useful option when drilling conditions require additional turning force rather than maximum bit speed.

Powered by a 0.50 HP pneumatic motor, the Ingersoll Rand 728LA2 features a trigger-start pistol grip configuration and non-reversible operation for forward drilling. Its standard-duty keyed chuck provides a conventional method of securing drill bits, while the 7.3" overall length and 2.5 lb weight, measured with the chuck, help operators assess tool handling and clearance. The 0.9" side-to-center distance describes the clearance from the drill's spindle centerline to the side of the tool, which is useful when drilling near adjacent surfaces. With a 1/4" NPT air inlet and 19 CFM air consumption, the 728LA2 can be incorporated into a suitably sized compressed-air system. Ingersoll Rand positions the 728 Series as an economical general-purpose drill family for maintenance applications.

Features:

• 2,100 RPM free speed provides a moderate-speed drilling option for maintenance tasks where controlled material removal is preferred over higher rotational speed.
• 54 in-lbs maximum working torque offers greater turning force than the 3,800 RPM 728JA1 model for applications requiring additional torque.
• 0.50 HP air motor delivers the manufacturer's specified power output for general-purpose drilling operations.
• 3/8" standard-duty keyed chuck accommodates compatible drill bit shanks and allows mechanical tightening using a chuck key.
• Trigger-start pistol grip arrangement provides straightforward drill activation and familiar handling for repair and maintenance personnel.
• Compact 7.3" overall length and 2.5 lb weight support handheld use in general workshop and equipment-servicing environments.
• Non-reversible configuration provides forward drilling operation without an additional reverse control.
• 728 Series construction is intended to withstand repeated drops and harsh working environments encountered during maintenance work.

Applications:

• Industrial maintenance and MRO – Drilling mounting holes, repairing machinery brackets, and preparing replacement components during routine equipment servicing.
• Automotive and fleet workshops – Performing appropriate drilling operations on accessible brackets, panels, and repair components during vehicle maintenance.
• Metal fabrication – Drilling holes in fabricated metal parts where the selected drill diameter and workpiece material call for moderate rotational speed.
• Manufacturing and general assembly – Preparing holes in fixtures, workpieces, and equipment components using a forward-only pneumatic drill.
• Mechanical repair and workshop operations – Supporting routine drilling tasks on compatible materials when a reliable compressed-air supply is available.

FAQs:

• Q: What is the difference between the Ingersoll Rand 728LA2 and 728JA1 maintenance drills?
  A: The 728LA2 operates at 2,100 RPM with 54 in-lbs of maximum working torque, while the 728JA1 operates at 3,800 RPM with 30 in-lbs. Both have 0.50 HP rated power and 3/8" chuck capacity. The 728LA2 favors additional torque, while the 728JA1 favors higher drilling speed.
• Q: What air compressor capacity does the Ingersoll Rand 728LA2 require?
  A: Ingersoll Rand specifies 19 CFM (538 L/min) air consumption and a 1/4" NPT air inlet. Select a compressor and air supply system capable of delivering the required airflow at the manufacturer's recommended operating pressure. Consider losses through hoses, couplings, and air preparation equipment when sizing the system.
• Q: Does the 728LA2 have a reversible drilling function?
  A: No. The 728LA2 is a non-reversible pneumatic drill intended for forward drilling. Applications requiring reverse rotation should use a drill model specifically equipped with that function.
• Q: Does the 728LA2 have a keyed or keyless chuck?
  A: The 728LA2 uses a standard-duty 3/8" keyed chuck. Ingersoll Rand identifies the 728L6K as the corresponding 2,100 RPM configuration with a keyless chuck. Choose the chuck arrangement that best suits your drilling and bit-changing requirements.
• Q: Can the 728LA2 be used to drill steel or other metals?
  A: Yes, when the drill bit, workpiece material, and drilling conditions are appropriately matched. The 2,100 RPM rating is the tool's free speed, not a universal recommended cutting speed. Consult Ingersoll Rand's drilling speed guide to select the correct bit diameter and operating conditions for the material.
