Ingersoll Rand offers a complete range of DC fastening tools in straight, right angle and (a unique) push-to-start  configurations. 
Ingersoll Rand DC fastening tools have built in torque transducers. The torque delivered by the tool is dynamically measured by the transducer and through a closed loop micro processor control, the tool is shut off when the desired torque is achieved. Angle control is attained through a resolver interfaced with the closed loop system. Advance strategies such as fastening to yield are achieved through algorithms.
The new IR QE-IC series fastening systems are the realization of an investment in innovation and technology that promises and delivers an unparalleled level of performance. The new QEIC systems perform dramatically better than existing closed-loop DC platforms in improving productivity, reducing cost of ownership and maintenance, and offering a proven means of tightening critical assemblies.

Tools:

Four motor platforms named the QE2, QE4, QE6 and QE8 include tools in angle, inline, push-to-start and pistol configurations.

Productivity:

• Faster speeds at torque
• Improved accuracy with Sine Drive technology
• Programmable momentary switch
• Modular designs offer optimum flexibility.

Ergonomics:

• Lightweight design
• Compact package
• Comfortable grip surfaces and smooth contours
• Low-force trigger and rotary reverse switch

Reliability:

• Digital Link between tool and controller
• One-piece rugged chassis
• Improved gear and cable life
• Non-contacting switches
