To select the right OSG tap, match the thread size (e.g., 1/4"-20 UNC), thread class (H1 / 2B-3B), and chamfer type (plug for general use) to your material and hole type. For blind holes, spiral point taps push chips forward; for through holes, consider spiral flute taps. Always verify coating and material compatibility.
