JIS Spiral Flute Taps With No Coating

Wilson's JIS Spiral Flute Taps With No Coating have significant advantages in quality control, and rigorous quality ensures product stability and reliability. It is suitable for machining materials such as cast iron and aluminum, and can effectively prevent the formation of chip blocks. It is an economical and affordable choice for conventional processing needs in the automotive, general machinery, hardware and other industries.

Product features

1.Strictly bench marking against JIS standards and quality certification

The entire production process closely follows JIS B 4401 and JIS B 4403 standards, with clear specifications for the dimensional accuracy, tooth profile angle tolerance, and surface roughness of the tap. Let's talk about the pitch tolerance, which will be strictly controlled within a very small range to ensure a seamless fit with the workpiece thread. At the same time, through international quality system certifications such as ISO 9001, every step from raw material procurement to finished product delivery follows standardized processes to ensure consistent quality.

2.Fine inspection of raw materials at every level of quality control

For raw materials such as high-speed steel and powder high-speed steel, testing is particularly strict. Carefully analyze the content of carbon, tungsten, molybdenum and other elements with a direct reading spectrometer, without any carelessness; Use a metallographic microscope to observe the distribution of carbides, ensuring that the particles are fine and uniform, and avoiding any defects in the material that may affect the performance of the tap. Only raw materials that have passed comprehensive testing can enter the production process and ensure quality control from the source.

3.Accurate monitoring in critical processes

High precision equipment and professional methods are used to monitor key processes such as machining spiral grooves and heat treatment. For example, using a tool microscope to detect the angle of the spiral groove and the fillet of the cutting edge, the error is controlled within a very small range; During heat treatment, use an infrared thermometer to monitor the quenching temperature and holding time to ensure that the hardness of the tap reaches 62-66HRC, making the cutting edge both wear-resistant and tough, and more convenient to use.
