MODEL
High-speed steel straight groove spiral groove machine tap is an efficient tool for machining internal threads. It is made of high-speed steel and has the characteristics of strong wear resistance and stable cutting performance. The straight groove tap has a simple structure and is suitable for through-hole and short-chip material processing. The iron chips are discharged forward during cutting; the spiral groove tap realizes upward chip removal through the 15°-50° helix angle design, which is particularly suitable for blind hole processing. It can effectively improve the surface quality of the thread and extend the tool life. The machine design is suitable for CNC centers or tapping machines. The high-speed steel material supports higher cutting speeds. Among them, the spiral groove tap has become the first choice for difficult-to-process materials due to its smooth chip removal and good centering.
