How to select the correct OSG STI tap for steel?

Select an OSG STI tap based on thread size (e.g., 1/2"-13 UNC), material (steel or stainless steel), and required thread class (H4 / 2B-3B). Spiral-flute taps are ideal for through holes in steel as they eject chips upward. Always match the tap to the insert manufacturer's specifications for proper fit.
