12mm Machine Tap DIN 374C HSS-Co Vapourised Form C MF12x1.25 6H Blind Hole, 9mm Shank - TECWERK

Take advantage of the combination of HSS‑Co toughness, a 40° helix for improved chip evacuation and ISO2 (6H) tolerance for consistently accurate metric fine threads; order directly via Metav Werkzeuge or ask the consultants for specification support.

Machine tap DIN 374C Univ. M12 x 1.25 HSS‑Co, 40° helix – TECWERK

A universal machine tap, Machine tap DIN 374C Univ. M12 x 1.25 HSS‑Co, designed for producing precise metric fine threads in blind holes across a range of engineering materials.

• HSS‑Co for high wear resistance
• 40° right‑hand helix for chip control
• ISO2 (6H) tolerance for exact thread fit
• 9 mm shank for robust toolholding

Consistent cutting performance through cobalt high‑speed steel

The use of HSS‑Co (cobalt high‑speed steel) delivers improved hot hardness and extended tool life compared with standard high‑speed steel. This material choice means fewer tool changes and more predictable process windows when machining steel, stainless steel or non‑ferrous metals. For production environments where downtime is costly, the alloyed substrate maintains cutting edges under elevated temperatures, reducing wear and ensuring that thread quality remains within specification over longer batches.

Accurate fine threads with DIN conformity for reliable assemblies

Compliant with DIN 374C and intended for metric ISO fine thread M12 x 1.25, the tap meets established standards for thread geometry and quality. The ISO2 (6H) tolerance class ensures a consistent internal fit, which minimises assembly play and the need for rework. The form and relief of the cutting flanks are engineered to reduce insertion torque and lower the risk of thread distortion, delivering reliable thread profiles for components that demand precise mating and repeatable performance.

Optimised chip evacuation and surface finish for blind‑hole tapping

A 40° right‑hand helix provides aggressive chip control, particularly advantageous when forming threads in blind holes, as chips are guided away from the cutting edge and out of the hole more effectively. The tap’s vapourised coating improves lubricity and wear resistance in interrupted cuts, while the flank relief reduces friction at the thread flank, aiding surface finish and reducing the tendency to gall. The 9 mm shank secures the tool in standard collets and holders for stable machining under power tapping conditions.

Practical benefits for workshop and production use

The universal design and material compatibility make this tool suitable for general workshop and industrial use where fine threads are required across mixed workpiece materials. By standardising on a robust thread‑forming tool that adheres to DIN/ISO norms, procurement can reduce variant stock while maintaining process reliability. For technical clarifications or application advice, Metav Werkzeuge provides specification guidance and can advise on machine settings and coolant strategies to match the chosen workpiece material and tapping cycle.
