How to select the correct OSG tap for steel threading?

For threading steel, select an OSG spiral flute tap for blind holes or a spiral point tap for through holes. Match the thread size (e.g., 1/4"-28 UNF) and tolerance class (e.g., H3 / 2B-3B) to your application. Consider material hardness and hole depth; OSG taps are engineered for precision and durability in steel and stainless steel.
