To select the correct OSG extension tap, match the thread size (e.g., M6x0.75) and tolerance class (e.g., D4 / 4H-6H) to your hole requirements. Consider material type—OSG taps are designed for multiple materials. For blind holes, choose a modified bottoming chamfer; for through holes, a plug chamfer may suffice. Always verify the flute count and coating for your application.
