How to select the right OSG tap for a threading application?

Select an OSG tap based on thread size, material, and hole type. For through holes, a spiral point tap like the 1240208 pushes chips forward. Match the tap tolerance (e.g., H5) to the required thread class (2B-3B). Consider coating for tool life; TiCN suits ferrous materials.
