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.

Cuts great male and female threads. Nice and tight.

How can a tap and die set be superior to another? Their made to spec. This set was simply cheaper than the others and works just fine. That was enough reason for me to but them.

Used to tap hole for 6-32 brass machine screws. Worked great. Only problem was the die was smaller diameter, and I had to buy tools to hold the tap and die. I should have read the description better.

A decent balance between quality and price for a rare and archaic thread type (12-32 UNEF).

I needed to make some small screws for someone of varying length. Used both the tap and the die. The tap was used to hold the threaded screw so I could cut a slot in the screw. So the tap and die bot worked well and the screws fit the other person's equipment.

The tap seem to be halfway decent, but the die is way under size sent the item back

Sometimes SSD 2.5" to 3.5" adapters aren't threaded. This fixes that problem.
