Information
When tapping, appropriate lubricating oil is good for cutting or cooling, making the cutting easier and faster, improving the smoothness and dimensional accuracy, and helping to extend the service life.
The following lubricants are recommended: steel - cutting oil, machine oil; pig iron - dry oil; aluminum - kerosene; stainless steel - mixed kerosene; hard plastic - dry oil. Be sure to select the appropriate cutting oil for complex tapping process and apply anti-rust oil for maintenance after use.
Round Threading Dies
The round dies can process, correct or clean external threads. Conical locking hole, strong locking and not loose. Great for maintenance and repair work on pipes, boards and machinery.
Applications
Perfect for rethreading existing threads in hard materials like metal, or making new threads in softer material such as plastic.
Easy to Use
Suitable for tapping stainless steel, aluminum alloy, cast iron, copper, iron, aluminum, plastic, etc.. NOT suitable for tile, concrete, walls, stone, etc.
Alloy Tool Steel Dies
- High hardness
- Wear resistance
- High hardening capacity
- Tempering resistance
Tips for Round Dies
The end of the bar should be chamfered 1*45 degree, and the chamfer is too large to cut in. 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.
It needs to be reversed every 1/4~1/2 turn to facilitate the chip discharge from the chip hole. When tapping, add suitable lubricating oil to the cutting edge, and repeat the operation 3-4 times until the thread length is obtained. When using by hand, pay attention to even force and avoid blind force.
Straight Flute Thread Taps
Straight flute design, downward chip removal, fast tapping with accuracy. Suitable for processing through holes or shallow blind holes. Perfect for drilling and tapping aluminum, zinc, alloy etc..
Easy to Use
Used on drilling machines, tapping machines, CNC and milling machines. Use with tapping oil to get higher quality threads and more durable taps.
Coatings
Features just the base substrate without any additional coatings, suitable for wide ranges of applications.
High Speed Steel Taps
- High hardness
- High wear resistance
- High heat resistance
- Good process performance
- Good strength and toughness
