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
Can process, correct or clean external threads. For tapping stainless steel, aluminum alloy, cast iron, copper, iron, aluminum, plastic, etc.. NOT suitable for tile, concrete, walls, stone, etc.
Alloy Tool Steel Die
It has high hardness, wear resistance, high hardening capacity and tempering resistance. Great for maintenance and repair work on pipes, boards and machinery.

Tips
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.
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.
