1.Size:3/8-32 Unef


  • Round Die: Thread size: 5/16-32 UNEF; outside diameter (OD): 25mm / 1.0"; Thickness: 9mm / 0.35"; accuracy class: 6g. Made of alloy tool steel, hardness, high torque, good toughness and wear-resistance.
  • Applications: Can process, correct or clean the external threads. Suitable for general purpose threading in stainless steel, aluminum alloy, cast iron, copper, iron, aluminum, plastic, etc.. Great for maintenance and repair work on pipes, boards and machinery.
  • Features: Conical locking hole, strong locking and not loose. Perfect for re-threading existing threads in hard materials like metal and making new threads in soft material such as plastic. The surface is lubricated with grease to prevent rust, the thread is clear and easy to repair.
  • Easy to Use: The positioning groove of the die should be aligned with the fastening screw in the middle of the die wrench, and the screw should be inserted into the slot of the die and tightened. The end of the bar should be chamfered 1*45 degree, and the chamfer is too large to cut in.
  • Tips: It needs to be reversed every 1/4~1/2 turn to facilitate the chip discharge from the chip hole. Suitable lubricating oil should be added to the cutting edge of the die when tapping the thread. The bar diameter should be smaller ( about 0.05mm-0.15mm) than the nominal diameter of the required thread. Excessive diameter can easily cause difficult cutting and lead to damage to the die teeth.

Information

  • Dies can process external threads, and be divided into a cutting part, a positioning part and a chip hole. Dies have round dies, square dies, hex dies according to the shape. They are also called as ordinary thread dies, pipe thread dies and tapered pipe thread dies according to the purpose.
  • Use chip fluid (oil) to obtain quality threads, and it is also suitable for thread maintenance. Suitable lubricating oil is conducive to cutting or cooling, making cutting easier, improving smoothness and dimensional accuracy.

Applications

  • Round threading dies are suitable for general purpose threading.
  • Can process, correct or clean the external threads. Good for maintenance and repair work.

Lubricating Oil

  • Lubricant should be applied to the cutting edge. It can help to extend the service life of tools in tapping operations.
  • Suitable lubricating oil is conducive to cutting or cooling, making cutting easier, improving smoothness and dimensional accuracy.
  • It needs to be reversed every 1/4~1/2 turn to facilitate the chip discharge from the chip hole.

Notice

  • Check the specification and outer diameter of the die and the clamping range of the die wrench to ensure that the two match. Choose a suitable screwdriver to unscrew the fixing screws on the main body of the die wrench.
  • Put the die into the clamping body of the die wrench, and turn the die slightly to make the side hole of the die consistent with the position of the wrench fixing screw.
  • Tighten the screws with a suitable screwdriver, so that the die and the wrench can be closely combined. When operating the tapping tool into a semicircle, it must be retracted to ensure that the chips are discharged in time.

I was pleased how well this chased threads and cut new threads. I bought it for tire valve stem threads. I have TPMS caps on my wheels to monitor temperature and pressure when traveling but one wheel had a leak. There wasn’t quite enough threads for that cap to seal so I easily cut new threads to accommodate it and stop the leak.
