Machine tap DIN 371B M5 x 0.8 mm — HSS‑Co, Form B, straight‑fluted

Machine tap DIN 371B M5 x 0.8 mm HSS‑Co 6H TECWERK is a metric ISO tap for efficient production threading in a wide range of steels and general workshop applications

• Cobalt HSS for increased wear resistance
• Straight‑fluted Form B for reliable chip evacuation
• ISO2 (6H) tolerance for tight, repeatable threads
• Shank Ø 6 mm for secure clamping

Consistent productivity for repetitive threading operations

The combination of HSS‑Co material and a Form B straight‑fluted geometry delivers a balance of hardness and toughness that suits serial production. This threading tool is specified to metric ISO standards (DIN 13 Sheet 1) and produced to ISO2 (6H) tolerance, which ensures consistent, high‑quality threads across batches. Because the design includes a dedicated cut for through threads, downtimes caused by reworking or thread failures are reduced, supporting smoother workflows and fewer rejects.

Reduced machining effort and clearer process outcomes

A straight flute profile simplifies chip control in through‑hole tapping and lowers the risk of chip packing in blind holes when combined with correct coolant and feed parameters. The tool’s shank Ø 6 mm and compatibility with common collets or tap holders means quick tool changes and reliable clamping. For operations working with tougher materials, the cobalt alloy extends tool life so that maintenance intervals are longer and mean time between tool changes increases, which improves overall shop efficiency.

Practical compatibility with common workshop materials

Designed for use in steels up to approximately 900 N/mm², this threading tool is suitable for a wide range of general engineering steels and typical workshop alloys. The metric M5 x 0.8 mm specification matches standard components and fasteners, making the tap a practical choice for repair, maintenance and small‑batch production tasks. Clear technical standards and tolerances facilitate integration into quality control processes and help maintain interchangeability with existing hardware.

Confidence through standards and supplier support

Selecting a tap manufactured to DIN and ISO standards reduces uncertainty during procurement and inspection. The combination of standardised geometry, defined tolerances and an alloyed high‑speed substrate provides predictable performance and easier process documentation. Paired with a dependable supplier, the tool becomes part of a dependable supply chain that supports traceability and long‑term planning in production environments.

FAQ

What material is the tap made from and why is that important?
The tap is made from HSS‑Co (cobalt high‑speed steel); this material increases wear resistance and toughness, extending tool life under higher cutting stresses.

Which thread and tolerance does the tool produce?
The tool produces a metric M5 x 0.8 mm thread to ISO2 (6H) tolerance, meeting DIN 13 Sheet 1 requirements for consistent, interchangeable threads.

Is the tap suitable for blind holes or only for through threads?
The tap is designed with a dedicated cut for through threads, optimising chip evacuation and performance in through‑hole applications; appropriate process adjustments are recommended for blind holes.

What clamping diameter is required for the tap?
The shank diameter is 6 mm, compatible with standard tap holders and collets used in machining centres and tapping units.

Can this tap machine harder steels?
The tool is specified for steels up to approximately 900 N/mm² tensile strength; selection should consider workpiece material and machining parameters.
