LOW SPIRAL TAP ( HS )

Low Spiral Tap ( HS )

Spiral taps are aimed at blind hole tapping operations. The spiral angle and shape of the groove are specially designed. The most suitable spiral angle can make the cutting chips smoothly and smoothly discharged from the hole, and the groove shape can make the cutting chips become Small and crimped, for carbon steel, alloy steel and non-ferrous metals to be cut, it has excellent durability and can obtain good precision, so it has a better life. Generally, the length of inverted teeth for blind holes is 2.5 teeth. High-vanadium high-speed steel with high toughness and wear resistance is often used.
