TECWERK machine tap M12 x 1.25 mm — HSS‑Co, Form C, DIN 374C

The TECWERK machine tap M12 x 1.25 mm is a high-performance machine tap for producing metric fine threads (DIN 13) in blind holes, designed for industrial use in steels, malleable cast iron and long‑chipping non‑ferrous metals

• HSS‑Co construction for enhanced hardness and wear resistance
• Form C geometry with 40° right‑hand helix
• Flank‑honed cutting edges for improved chip control
• Suitable for blind holes; tolerance field 6H

High productivity and consistent thread quality for industrial tapping

The combination of HSS‑Co material and precise Form C geometry delivers a balance of toughness and cutting performance that supports higher cycle rates in production environments. The cobalt alloy increases heat resistance and edge retention during machining of tougher steels up to approximately 1000 N/mm², reducing the frequency of tool changes and downtime. As a result, process reliability and component repeatability improve, which is particularly important in series production and maintenance operations.

Clear guidance on materials and application scope

Designed for metric fine threads in accordance with DIN 13, the tool is optimised for blind‑hole tapping where controlled chip formation is essential. The specification “M12 x 1.25 mm” denotes a fine thread profile, while the 6H tolerance field ensures compatible fit with standard mating parts. The tool is suitable for use in steels, malleable cast iron and long‑chipping non‑ferrous metals, offering versatility for workshops handling mixed batches or repair work across different materials.

Geometry and chip control explained for safe, reliable results

A 40° right‑hand helix combined with flank‑honed cutting edges promotes predictable chip flow and reduces the risk of chip jamming in blind holes. The honed flanks lower cutting forces and improve surface finish by smoothing the engagement between tool and workpiece. In practice, this geometry helps maintain machine spindle and tapping head life while producing clean internal threads with minimal rework.

Compatibility, mounting and operational considerations

The tool’s shaft Ø 9 mm allows secure clamping in common tapping fixtures and tooling systems used on CNC machines and tapping heads. Designed as a machine tap for power tapping operations, the component benefits from controlled feed and rigid support to exploit the HSS‑Co material advantages fully. Appropriate coolant and correct spindle speeds for the workpiece material further enhance tool life and thread accuracy.
