Somta Somta Series 511 - HSS Straight Flute Short Hand Bottom (Finishing) Tap MF25 x 1.5mm

HSS Metric Fine Tap M25 × 1.5 Bottom – Somta Series 511

The SOMTA 5112503 – M25 × 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.

• Bottoming Chamfer – Designed for full-depth threading in blind holes with minimal lead-in space.
• Fine Pitch Threading (M25 × 1.5) – Ideal for applications requiring close thread engagement and tight tolerances.
• HSS Material – Ensures strength, heat resistance, and extended tool life under repeated use.
• Straight Flute Design – Suitable for short-chipping materials and versatile tapping operations.
• Short Hand Tap Style – Compact length enhances control and accessibility in confined setups.
• Right-Hand Thread – Standard cutting direction compatible with most metric systems.
