  • Round Die: Thread size: 1/2-28 UNEF; outside diameter (OD): 38mm / 1.5"; Thickness: 10mm / 0.4"; 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.

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.

Had to clean burrs from the starting threads on the die before I could cut decent threads with it. Now it is fine.

I used this to clean up buggered threads on a rifle barrel. It could be because of my inexperience, but about half way down the threads it started to get difficult to turn. on inspection the cutting teath were starting to fracture and break. Oil was used and I was careful on the start and cutting motinos. I bought cheap,and cheap is what was delivered.

It's a die. It does what it is supposed to do. I'm happy with it.

It seems well made for the price. I was able to smooth out some threads on my freedom stick. I had a whisper pickle that would get stuck on the first thread. After working this to and fro about 20 times, there is a tremendous improvement.

I had no problems starting the die or with it cutting the threads. The threads were a nominal fit with no wobble.

This die is way, way too small to fit a 1/2 thread adapter tool. The thread is too big to be anything else, but it is clear that poor machining and measurement went into making this.
