The hardness of HSS M35 after heat treatment is higher than HSS 6542 (M2). The Aluminum Titanium Nitride (AlTiN) coating on a thread tap can effectively improve the high-temperature processing life of taps and provide higher surface hardness. Feature - Straight fluted taps have a good effect on processing materials with high hardness, materials that are prone to tool wear, through and blind holes with short tapping depths. The 4 straight flute design of the tap allows for efficient chip removal during the threading process. Application - Thread milling taps are versatile tools used for creating precise and durable internal threads in metalworking industries and applications, ensuring accurate results on ordinary lathes, drilling machines, and tapping machines.
