TECWERK Machine Tap DIN 374B MF14×1.5 HSS‑Co 6H

The TECWERK Machine Tap DIN 374B MF14×1.5 HSS‑Co 6H is a straight‑fluted, Form B machine tap for producing fine metric threads in through‑hole applications.

• HSS‑Co for improved wear resistance
• Form B straight flutes for stable chip formation
• Tolerance class 6H for consistent thread fit
• Shank Ø 11 mm for secure machine clamping

Accurate fine threads with industrial tolerance

The machine tap is engineered to produce MF14×1.5 metric ISO fine threads in accordance with DIN 13, meeting the 6H tolerance class. The use of cobalt high‑speed steel (HSS‑Co) ensures a combination of edge stability and heat resistance, which translates into predictable dimensional results and fewer rejects in serial production. For engineers and production planners this means reproducible thread geometry and reduced rework rates, supporting tighter process control on fine‑thread components.

Designed for through‑hole productivity and chip control

Form B straight flutes and a dedicated peel chamfer for through threads make this tap efficient when cutting through holes. The straight‑flute geometry promotes controlled chip breaking in long‑chipping non‑ferrous metals and temper‑cast materials, while the chamfer reduces lead‑in torque and minimises risk of thread distortion at entry. The shank Ø 11 mm provides a secure interface with standard machine holders, supporting steady rotation and axial guidance during tapping cycles.

Robust geometry for demanding materials

The tool is suitable for use in steels with tensile strength up to approximately 1,000 N/mm², temper cast iron and long‑chipping non‑ferrous alloys. The flanks are relief‑ground, which reduces friction along the thread flanks and lowers cutting forces; this improves tool life and surface finish. Where consistent thread quality is required across mixed batches of materials, the combination of material choice and flank treatment helps maintain performance under elevated cutting temperatures and variable cutting conditions.

Practical integration into workshop and production workflows

As a machine tap for production use, this item supports straightforward handling and inventory management. The compact specification and compatibility with standard tapping spindles simplify setup; the robust HSS‑Co composition and design choices reduce downtime linked to frequent tool changes. For purchasing departments and workshop managers, the product offers a dependable option to consolidate tooling needs while maintaining the precision required for fine‑thread assemblies.

FAQ

Is this tap suitable for fine metric threads in compliance with DIN standards?
Yes. The TECWERK machine tap produces metric ISO fine threads (MF 14×1.5) and conforms to DIN 13 with a 6H tolerance class for industrially reliable fits.

Which materials can be machined with this tap?
The tap is suitable for steels up to approximately 1,000 N/mm² tensile strength, temper cast iron and long‑chipping non‑ferrous metals, as specified for the TECWERK machine tap.

What does Form B straight‑fluted mean in practice?
Form B indicates a straight‑fluted design that provides stable chip formation and is particularly effective for through‑hole tapping when combined with the peel chamfer present on this tool.

What is the shank diameter and how does it affect machine mounting?
The shank diameter is 11 mm, which ensures a secure clamping interface with common tapping holders and reduces run‑out during high‑precision tapping operations.

Does the tool include any geometry to aid chip removal in through holes?
Yes. The tool features a peel chamfer for through threads, designed to lower lead‑in torque and assist chip evacuation when cutting through holes.
