uxcell 1/2-16 UNF HSS Bottom Tap

This uxcell hand bottom tap is designed for creating or re-tapping threads in mild steels, aluminum, iron, copper, and hard plastics. Made from M2 (6542) High Speed Steel, it offers excellent hardness, wear resistance, and heat resistance for a long service life. The straight groove design facilitates chip removal and reduces operating resistance for efficient processing, resulting in clear, burr-free threads. For optimal results, use appropriate tapping oil and consistent pressure. Ideal for tapping through or shallow holes, and for re-tapping damaged or stuck threads.
