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.
