How to select the right OSG spiral point tap?

Select based on thread size (1/4"-20 UNC), hole type (through-hole), material, and tolerance class (H2 / 2B-3B). Spiral point taps are best for through holes as they push chips ahead. Match tap coating to workpiece hardness. 3G Electric can help with application-specific recommendations.
