How to select the correct CHICAGO-LATROBE tap for a job?

Select a tap based on thread size, material, and hole type. For through holes, a spiral-point tap like the CHICAGO-LATROBE #12-24 UNC pushes chips ahead. For blind holes, use a spiral-flute tap. Match the chamfer type (plug, bottoming, or taper) to the hole depth. Always verify the thread class (e.g., 2B) and material hardness.
