Features and Benefits

What's New?

  • Terminal strip has been replaced with new wiring harness which provides increased reliability and takes up less space inside the reamer, making it easier to service and replace
  • New easy access setup switches are durable, waterproof, and fully protected from the elements without requiring the use of external flap protection
  • Check valve has been upgraded to a more robust and durable design
  • New wiring harness, setup switches and check valve are all common across both the TOUGH GUN TT3 and TT3E Reamer platforms

Safe and Accurate Setup

  • External setup switches allow independent operation of the sprayer, clamp and spindle during manual setup
  • Cutter blade lifts into position but does not spin when activated by the spindle setup switch

Ease of Maintenance

  • All wiring connections are built into the new wiring harness, reducing the risk of wiring errors during maintenance
  • Improved wire labeling for easy identification

Dependable Performance


  • 3/4 Horsepower lubricated air motor with gear reducer provides the high torque required for spatter removal at the lower speed needed to protect the spindle and cutter blade from excessive wear
  • No damage will occur to the air motor if stalling occurs
  • Operates in any position


  • Spindle has rotating rod accuracy of 0.001" - 0.004" at its extended position for cutting repeatability and optimized spatter removal
  • Fixed motor, clamp and v-block provide cutting accuracy and repeatability – No manual adjustments to nozzle clamps, cutter height, or motor height are required

Increased Reliability

  • Sprayer reservoir is located on the opposite side of the unit as an additional safeguard against overfilling / leakage onto internal electronics
  • All pneumatic valves are internally mounted
  • External setup switches are protected and seals protect points of entry

This dedicated motor lubricator maximizes performance and protects your TOUGH GUN™ Reamer investment by extending the life of the motor, and is highly recommended for use in damp and moisture rich environments. Factory set for optimal pneumatic oil lubrication, the lubricator is available as an option when configuring your new unit* or is retrofittable to your existing TOUGH GUN TT3 Reamer.

*Ordering your new TOUGH GUN Reamer with the factory-installed lubricator option increases your warranty from 1 to 2 years, or increase your warranty to 3 years with the factory-installed lubricator option plus exclusive use of TOUGH GARD™ Anti-Spatter Liquid.




Filter / Regulator

The Filter / Regulator unit from Tregaskiss is another recommended accessory that helps extend the life of your TOUGH GUN Reamer. The filter cleans the air supply to the reamer and restricts debris from reaching the motor, keeping it uncontaminated and ensuring maximium performance and longer life, while the regulator works to ensure optimal air pressure is achieved at the unit.



Spray Containment

The innovative Spray Containment unit from Tregaskiss helps prevent air contamination by catching anti-spatter overspray in its sealed basin, improving the air quality of the working environment and maintaining the cleanliness of the weld cell. Click here to learn more.

Nozzle Detection

Nozzle Detection for the TOUGH GUN TT3 Reamer uses a proximity sensor mounted on the side of the reamer that can be used independently of the ream cycle. The robot positions the front end of the MIG gun close to the sensor to detect the presence of the nozzle. If the nozzle is present, a signal is then sent back to the robot controller or PLC. Learn more about the nozzle detection system.
