QE & QM Series Tool Model Numbering System

When an application calls for straight, in-line fixtured spindles, the user can choose between QE or QM spindles. 
As a guideline, QE spindles are recommended for normal duty applications that require very high rundownspeeds and where there is a moderate cycle rate. They are suitable for most industrial applications.
QM spindles are recommended for heavy duty applications that involve high cycle rates or installation on automatic stations. They offer a maximum durability and the most robust solution for such applications.

QE Series DC Electric Tools

QM Series DC Electric Tools

The Ingersoll Rand series of QE-DC electric tools uses a ‘smart’ numbering system to describe the tool and its features.

• The first 3 digits in the numbering system describe the tool series by motor size. There are 3 basic sizes:
  • QE4
  • QE6
  • QE8

   

• The next digit describes the body style. There are 6 different styles:
  
  • Angle
  • In-line
  • Offset
  • Pistol
  • Push-tostart
  • Motor
    
    • (which is an in-line tool that has no output spindle but can be used for adaptation for special attachments)
      
  • It is important to note that not all 3 series of tools have all 6 styles available.

   

• The next digit describes the method of tool start activation. There are 4 manual methods:
  • Trigger
  • Lever
  • Extended lever
  • Push-to-start
    
  • Remote start
    • (where the start signal is activated from an external source)

     

• The following 3 digits specify the tool’s maximum torque capacity in Nm.
  
  • Tools that have a maximum torque capacity of less than 100Nm have a 0 as their first digit.

   

• The next digit describes the method of mounting or fixturing the tool. There are 5 methods available depending on the model type:
  
  • Standard gear case
    
    • (which has no mounting method)
      
  • integrated flange
  • 2 styles of splined bolt-on mounting plates
  • mounting plate with an integral torque reaction bar

   

• The final 5 digits describe the output spindle. The first 2 digits of this group describe the spindle type and size, the next digit the drive type and the last 2 digits the drive size.

The Ingersoll Rand series of QM-DC electric tools uses a ‘smart’ numbering system to describe the tool and its features.

• The first 3 digits in the numbering system describe the tool series by motor size. There are 4 basic sizes:
  • QM3
  • QM5
  • QM7
  • QM9

   

• The next digit describes the body style. There are 2 different styles:
  
  • Straight
  • Motor
    
    • (The power unit is an in-line tool that has no output spindle but can be used for adaptation for special attachments.)

     

• The next digit describes the sensor options. There are 6 options:
  • Transducer
  • Transducer blank
    • (for loosening applications where a transducer is not required)
      
  • Power Unit
    • (no transducer)
  • Redundant Torque Transducer
  • Redundant Angle Encoder
  • Both Redundant Torque Transducer and Angle Encoder

   

• The following 3 digits specify the tool’s maximum torque capacity in Nm.
  
  • Tools that have a maximum torque capacity of less than 100Nm have a 0 as their first digit.

   

• The next digit describes the spring tension in the floating spindle. There are 3 options:
  
  • Light spring
    
  • Heavy spring
  • Solid (Locked) Spindle with no float
    

   

• The final 5 digits describe the output spindle. The first 2 digits of this group describe the spindle type and size, the next digit the drive type and the last 2 digits the drive size.
