Engineered for heavy-duty industrial drilling and demanding production applications, the Ingersoll Rand 6LR3 Inline Air Drill delivers an impressive 222.2 in-lb maximum torque with a 500 RPM free speed to provide exceptional drilling control and high torque output for larger drill diameters and difficult materials. Its inline configuration positions the pneumatic motor directly behind the spindle, allowing excellent balance and precise axial alignment for accurate drilling during continuous industrial operation.
The 6LR3 is designed for manufacturing, metal fabrication, machinery assembly, and maintenance environments where consistent pneumatic performance and operator control are essential. Its low operating speed allows greater cutting control while maximizing available torque, making it ideal for heavy-duty drilling applications. The streamlined inline design helps reduce operator fatigue during prolonged use while providing the durability and reliability expected from Ingersoll Rand industrial pneumatic tools.
