HSS Metric Fine Tap M25 x 1.5 Bottom – Somta Series 511
The SOMTA 5112503 – M25 x 1.5 Metric Fine Bottom Tap is engineered for precise internal threading near the base of blind holes. Crafted from high-grade High-Speed Steel (HSS), this tap delivers excellent cutting performance and wear resistance. It features a bottoming chamfer with only 1–2 threads engaged, making it ideal for finishing threads started with taper or intermediate taps. The fine 1.5 mm pitch ensures a tight, high-integrity thread profile suitable for applications that demand enhanced precision and sealing.
