How to select the right CHICAGO-LATROBE tap for my application?

Select based on thread size, material, and hole type. For through holes, a spiral point tap like the 280850 pushes chips ahead. For blind holes, use a spiral flute tap. Match the tap tolerance (e.g., H5) to your required thread class (2B-3B). Consult CHICAGO-LATROBE's technical data for material-specific speeds.
