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 have been a machinists for 15+ years and have used hundreds of taps/dies of various sorts. These are not going to good enough for a large production run, but if you just need to use them for a few parts or to clean up existing threads they are good enough to do it.I got these to clean existing threads and thread one shaft. It did it just fine but, the die is non adjustable so you can't adjust for wear or adjust the pitch diameter.

So you bought yourself that neato Harbor Freight and chainsaw beam cutting attachment but it didn't come with the proper bolt to mount it!? Well have no fears! This here is the exact die you need to make your own! Find a grade 5 or higher bolt the same size, but with about an inch and a half of shoulder, cut off the right hand threads, grind a chamfer, and start cutting some left hand threads. Don't be afraid to use some cutting oil while you're at it. You'll have yourself a custom, hand made left hand bolt long enough to mount that cool new beam cutter in no time!
