How to select the correct OSG spiral point tap for my application?

To select the correct OSG spiral point tap, match the thread size (e.g., 5/16"-18 UNC) and tolerance class (H7 / 2B-3B) to your workpiece material and hole type. Spiral point taps are ideal for through holes. Consider coating for tougher materials. OSG offers various chamfer types; plug chamfer is common for general use. Consult OSG's technical data for optimal performance.
