How to select the correct OSG extension tap for deep-hole threading?
To select the correct OSG extension tap, match the thread size (e.g., M6x1) and tolerance class (e.g., D5 / 4H-6H) to your application. For deep holes, choose a spiral-flute design with a modified bottoming chamfer to clear chips and thread near the hole bottom. Ensure the tap length provides sufficient reach without compromising rigidity. Consult OSG's technical data for material-specific recommendations.
