How to select the correct OSG spiral point tap for threading?

To select the correct OSG spiral point tap, match the thread size (e.g., #4-36 UNS), tolerance class (H2 / 2B-3B), and material compatibility. For blind holes, spiral point taps push chips forward; for through holes, consider spiral flute taps. Always verify the chamfer type (plug, bottoming, or taper) based on hole depth.
