About Taps

Straight flute design, made of 6542 high speed steel. It is used to process threads of various through holes or shallow blind holes. Can process copper, brass, A3 steel, aluminum, cast iron and other materials.

Generally used in conjunction with tapping machines, integrated bench drills, CNC lathes, machining centers, etc. Manual processing is also possible. When operating, control the speed according to the hardness of the material, the higher the hardness of the processed product, the slower the speed.

Recommended feed rate:

Hard steel: 5-10m/min, cast iron: 8-10m/min, ordinary steel: 6-15m/min.

About Dies

Made of alloy tool steel, hardness and wear resistance. Used to repair external threads. When in use, the conical locking hole of the die is aligned with the screw of the wrench and tightened. The conical keyhole has a strong locking force and is not easy to loosen.

Suggest:

Appropriate lubricating oil should be added to the die-cutting edge when cutting, It is to be reversed every 1/4~1/2 turn to facilitate chip discharge from the chip hole.

Tips

  • Please be sure to take protective measures when working, you need to wear goggles and protective gloves.
  • Before tapping confirm whether the diameter of the round hole is appropriate. Be sure to select the appropriate cutting oil for the complex tapping process and apply anti-rust oil for maintenance after use.
  • When tapping, control the speed according to the hardness of the material, it is necessary to add water or coolant to cool down to prevent excessive temperature and reduce tap loss.

I cannot speak to its durability as I had a one off use, really just for cleaning some existing threads. Locating left handed taps/dies is difficult, but found this set and it did the job for a reasonable price. (I used both the tap and die on the threads, and the fit to the existing threads was dead-on, and cleaned the threads so the item is usable again.)
