M6x1mm Single-Start Thread Tap DIN 352 Form B HSS-Co ISO2 (6H) With Chamfer For Through Holes, Uncoated - TECWERK

Take advantage of a hard-wearing HSS‑Co cutting material and a straight‑fluted Form B design to achieve consistent, ISO‑compliant M6×1 threads in steels up to approx. 900 N/mm²; order directly via Metav Werkzeuge or consult the Metav team for technical advice.

Single‑flute tap DIN 352 Form B M6×1 HSS‑Co ISO2 (6H) – TECWERK

The single‑flute tap DIN 352 Form B M6×1 is a straight‑fluted cutting tap designed for producing precise metric ISO threads, particularly suited to through‑threading in medium‑strength steels.

• HSS‑Co for high wear resistance
• Straight‑fluted Form B geometry
• ISO2 (6H) tolerance for metric threads

High performance and long tool life for medium‑strength steels

The use of HSS‑Co (cobalt‑alloyed high‑speed steel) increases hot hardness and wear resistance compared with standard HSS, which translates into longer service life under continuous production conditions. The tap is specified for steels up to approx. 900 N/mm² tensile strength, so the material choice ensures reliable cutting action where ordinary HSS would wear prematurely. This results in fewer tool changes and more predictable process windows, supporting efficient batch production and maintenance work alike.

Consistent, interchangeable metric threads to ISO2 (6H)

Designed to the DIN 352 Form B standard and compliant with DIN 13 Blatt 1, the tap produces M6×1 metric threads to the ISO2 (6H) tolerance field. This guarantees dimensional compatibility with standard fasteners and mating parts, reducing fitment issues in assemblies. The integrated cutting chamfer for through threads improves initial engagement and reduces the risk of cross‑threading when working with through holes, providing a dependable outcome for both series manufacture and repair applications.

Geometry engineered for chip control and breakage safety

The straight‑fluted Form B geometry combined with the single‑cut design helps control chip formation and evacuation in through‑threading operations. Flank relief (hinterschliffen) reduces radial contact and cutting forces, which lowers the likelihood of tap breakage under intermittent loading. Although the tool is uncoated, the cobalt alloy compensates by offering improved durability; the uncoated surface also facilitates straightforward resharpening when required, extending the useful life of the tool in a cost‑effective way.

Practical suitability and workshop considerations

This tap is particularly well suited to workshops, maintenance departments and production facilities that require repeatable metric threads with minimal setup complexity. As an uncoated HSS‑Co tool, it performs best with appropriate cutting fluid and controlled feed to maximise tool life and surface finish. Supplied as a single unit (packaging unit: 1), it integrates easily into existing tooling inventories and is a practical choice for both occasional repairs and regular production runs.

FAQ

What materials can this tap machine through?
The TECWERK single‑flute tap is specified for use in steels up to approx. 900 N/mm² and is therefore suitable for many common construction and alloy steels.

Does the tap produce standard tolerances for interchangeable threads?
Yes — the tool cuts metric threads to ISO2 (6H) tolerance in accordance with DIN 13 Blatt 1, ensuring compatibility with standard fasteners.

Is the tap coated or suitable for regrinding?
The tap is uncoated and made from HSS‑Co, which allows straightforward regrinding when edge restore is needed while delivering increased hot hardness during use.

What advantage does the straight‑fluted Form B offer?
The straight‑fluted Form B design aids chip control in through‑threading, simplifies chip evacuation and, combined with flank relief, helps reduce cutting forces and tap breakage.

Is this tap suitable for blind holes or only through holes?
The tool features a cutting chamfer optimised for through threads, but it may be used in other applications provided cutting conditions and chip evacuation are carefully managed.
