This spiral point tap is exclusively designed for threading stainless steel and its alloys, delivering optimal performance on the following grades:
Austenitic Stainless Steel: 304, 316, 316L, 301, 302 (most challenging to tap due to work-hardening properties, our tap effectively minimizes this issue)
Martensitic Stainless Steel: 410, 420, 440 (handles the toughness and hardness of quenched martensitic grades)
Ferritic Stainless Steel: 430, 409 (ideal for low-carbon ferritic grades with good corrosion resistance)
Stainless Steel Alloys: Stainless steel with high chromium, nickel or molybdenum content, stainless steel castings
Note: Also suitable for mild steel, carbon steel and low-hardness alloys, making it a versatile tool for mixed-material production lines.
