Ingersoll Rand 5LK1 Non-Reversible Inline Pneumatic Drill combines a 0.4 HP air motor with a 3,100 RPM free speed for efficient hole drilling in suitable materials. Part of the 5 Series, this compact air drill features a 1/4-inch chuck capacity for compatible drill bits and a 30.1 in-lbs maximum working torque for controlled drilling performance. Its non-reversible inline configuration provides forward-only spindle rotation, making it suitable for production tasks where reverse operation is unnecessary. The lever-start mechanism allows operators to activate the drill directly while maintaining control over the drilling operation.
The 5LK1 features a compact straight-body construction measuring 8.1 inches in overall length and weighing 2.0 lbs with chuck. Its inline arrangement positions the drill spindle along the tool body, making it suitable for direct-access drilling and repetitive workstation operations. A 0.8-inch side-to-center distance provides a useful clearance measurement when working near adjacent components or fixtures. The drill uses a high-quality chuck for secure retention of compatible drill bits and delivers a practical power-to-weight ratio for repeated drilling tasks. With 16 CFM air consumption, a 1/4-inch NPT air inlet, and a manufacturer-listed 74.6 dBA sound level, the 5LK1 provides defined operating specifications for integration into industrial compressed-air systems.

FAQs:
- Q: What is the operating speed of the Ingersoll Rand 5LK1 pneumatic drill?
A: The 5LK1 delivers a free speed of 3,100 RPM with a 0.4 HP pneumatic motor. Its maximum working torque is 30.1 in-lbs. - Q: What size drill bits can the Ingersoll Rand 5LK1 accommodate?
A: The drill features a 1/4-inch chuck capacity for compatible drill bits. The appropriate drilling diameter depends on the workpiece material, bit design, and operating conditions. - Q: Can the 5LK1 operate in reverse?
A: No. The 5LK1 is a non-reversible pneumatic drill with forward-only spindle rotation. It is intended for drilling tasks that do not require a reversing function. - Q: What compressed-air supply does the 5LK1 require?
A: The manufacturer specifies 16 CFM air consumption and a 1/4-inch NPT air inlet. The compressed-air supply should be appropriately sized to maintain the drill's required operating conditions. - Q: How does the 5LK1 compare with the Ingersoll Rand 5LL1?
A: Both are 5 Series non-reversible inline drills with 0.4 HP motors and 1/4-inch chuck capacities. The 5LK1 operates at 3,100 RPM with 30.1 in-lbs maximum working torque, while the 5LL1 operates at 2,300 RPM with 39.8 in-lbs maximum working torque. The 5LK1 offers higher rotational speed, whereas the 5LL1 provides greater working torque.
