Wilson have Spiral Point Taps in sale. It is also known as screw tip taps and front cut taps, and is divided into ISO SPiral Point Taps, DIN SPiral Point Taps, and JIS SPiral Point Taps. In the machining of through-hole threads, its performance is particularly outstanding. Speaking of which, its design is quite clever. There is a special spiral cutting edge at the front end, which is called the screw tip. Because of this screw tip, when tapping, the chips can be discharged forward along the spiral direction of the screw tip and leave the machining area in the direction of the tap feed. In this way, the chips will not pile up in the hole. Therefore, it is accurate to use it for threaded machining of through holes or shallow holes.
Looking at the structural design again, the angle of the cutting edge at the front end of the Spiral Point Taps is not arbitrarily determined, but is precisely calculated, generally between 10 ° and 15 °. This angle can make cutting more effortless, disperse cutting force, and reduce vibration during machining. Its handle and working part transition smoothly, so it can maintain stability during high-speed rotation. Moreover, many front-end taps use coating technology, such as TiN coating, which can make the surface harder, more wear-resistant, and reduce the friction coefficient; As for TiAlN coating, it is very awesome under high temperature environment, and suitable for processing high-strength materials. These coatings can help tap use longer.
Spiral Point Taps is mainly used to process through-hole threads, and there are also many materials that can be processed, such as low carbon steel, medium carbon steel, stainless steel, aluminum alloy, copper alloy, etc. It can often be seen in industries such as automobile manufacturing, mechanical processing, and electronic appliances. For example, it is indispensable for processing the through-hole threads on the engine cylinder block and the connecting threads on the electrical casing.
