Somta Somta Series 511 - HSS Straight Flute Short Hand Bottom (Finishing) Tap MF12 x 1.25mm

HSS Bottom Tap Metric M12 × 1.25

The SOMTA 5111203 – M12 × 1.25 HSS Bottom Tap is a precision tool designed for cutting fine-pitch internal threads in blind holes. Manufactured from high-speed steel (HSS), this bottoming tap features a short chamfer lead ideal for threading close to the hole base. The fine pitch (1.25mm) makes it perfect for applications requiring greater thread engagement and finer adjustment, such as in automotive, aerospace, and precision engineering components.

• Bottoming Chamfer (1-2 Threads) – Enables full thread depth in blind holes.
• Metric Fine Thread – M12 × 1.25 pitch offers higher strength and thread density than coarse threads.
• Straight Flute Design – Ensures steady cutting and efficient chip evacuation.
• High-Speed Steel (HSS) – Provides excellent wear resistance and tool longevity.
• Bright Finish – Reduces cutting friction and improves thread surface quality.
• Manual or Machine Use – Suitable for use in hand tapping or machine-based operations.
