Single‑flute thread tap DIN 352 Form B M5×0.8 HSS‑Co ISO2 (6H) TECWERK — straight‑fluted, uncoated metric tap for through holes

A Single‑flute thread tap DIN 352 Form B M5×0.8 HSS‑Co ISO2 (6H) designed for producing ISO metric internal threads in medium to high‑strength steels, optimised for clean chip removal and accurate thread geometry.

• HSS‑Co for increased wear resistance
• Straight flutes (Form B) for through holes
• ISO2 (6H) tolerance for precision fit
• Peeling chamfer for clean thread entry

Faster, more reliable threading in tougher steels

Made from HSS‑Co, this single‑flute tap delivers elevated red‑hardness and improved wear resistance compared with standard high‑speed steels, which translates into longer tool life when machining tougher workpieces. The straight‑flute Form B geometry supports effective chip evacuation in through‑hole applications; fewer chip jams mean shorter cycle times and less interruptive rework. The peeling chamfer (Schälanschnitt) eases thread engagement and produces a clean start, reducing the need for secondary operations and improving overall process efficiency.

Precision threads that meet industrial standards

Thread form and fit are critical in assembly. The tap conforms to DIN 13, Sheet 1 and produces metric ISO threads with the ISO2 (6H) tolerance field, ensuring consistent internal thread accuracy and interchangeability with standard fasteners. The combination of flank relief grinding and the chosen tolerance class reduces cutting forces and minimises the risk of seizure in medium‑strength steels up to approximately 900 N/mm² tensile strength. These characteristics support dependable assembly outcomes in production and maintenance environments.

Practical handling and process advantages

The single‑groove design concentrates cutting action and makes chip control predictable in continuous runs; this simplifies coolant access and cleaning routines. Although uncoated, the cobalt‑alloyed substrate maintains hardness under heat, so shorter dwell periods and stable feeds remain possible without premature flank wear. The tool’s geometry also reduces the tendency to create burrs at the thread start, which lowers finishing work and improves downstream quality control metrics.

Where this tap is most effective

Ideal for metalworking shops and production lines that require repeatable metric threadmaking in through holes, the tool suits applications in mechanical engineering, maintenance workshops and component assembly. The tap is particularly effective for medium‑to‑high strength steels where elevated thermal stability and wear resistance are required but coating is not essential. It also performs well where controlled chip formation and removal are priorities.

FAQ

What materials is this tap suitable for?
The Single‑flute thread tap DIN 352 Form B M5×0.8 HSS‑Co ISO2 (6H) is specified for use in steels up to approximately 900 N/mm² tensile strength and is designed for medium‑ to high‑strength steel applications.

Is the tap coated for improved wear resistance?
This TECWERK tap is uncoated; wear resistance is provided by the HSS‑Co substrate, which maintains hardness at elevated cutting temperatures.

What advantages does the straight‑flute (Form B) geometry provide?
Straight flutes facilitate predictable chip evacuation in through‑hole threading and help reduce chip packing, making the tool particularly effective in continuous production where clean chip removal is essential.

Does the tap produce threads to an industry standard tolerance?
Yes. Threads produced by this tap conform to DIN 13, Sheet 1 and are manufactured to the ISO2 (6H) tolerance field for a standardised fit with metric fasteners.

Can this tap be used for blind holes?
The design, including the peeling chamfer, is optimised for through holes; when used in blind holes, chip evacuation must be managed carefully to avoid chip accumulation.
