Machine thread tap DIN 371C M5 x 0.8 mm HSS-Co TiN 6H — TECWERK

The Machine thread tap DIN 371C M5 x 0.8 mm HSS-Co TiN 6H is a production-grade machining tool intended for forming accurate ISO metric threads in blind holes, especially in steel components up to 1000 N/mm² tensile strength.

• HSS-Co construction with TiN coating
• Designed for blind-hole tapping applications
• ISO metric M5 x 0.8 with tolerance ISO2 (6H)
• 40° right-hand spiral for efficient chip evacuation
• 6 mm shank for standard machine mounting

Industrial-grade accuracy reduces rework and inspection time

The tap is built to the DIN 371C form and delivers a consistent ISO metric thread (M5 x 0.8) with ISO2 (6H) tolerance, ensuring interchangeability and predictable fit. This high repeatability supports quality-controlled production where the focus is on minimizing rework and aligning with drawing tolerances. Specifying a tap with an established standard like DIN 371C simplifies process validation and reduces the time spent on final inspection.

Coating and substrate engineered for extended tool life

Made from HSS-Co (cobalt-alloy high-speed steel) and finished with a TiN coating, the tool balances toughness with surface hardness to resist built-up edge and abrasive wear. The TiN layer reduces friction at the cutting interface, which in turn helps achieve smoother thread flanks and longer tool life in cyclic production runs. These material choices make the tool particularly suitable for moderate to high-strength steels, where heat resistance and wear performance are essential for stable output.

Geometry optimised for blind holes and reliable chip control

The 40° right-hand spiral geometry coupled with relieved flanks promotes directed chip flow out of the thread root and reduces the risk of chip congestion in blind bores. For production lines that rely on machine tapping heads or automatic tapping units, this geometry supports unbroken cycles by lowering the incidence of tap breakage and the need for manual chip clearing. The 6 mm shank fits common collets and holders, providing secure clamping and repeatable concentricity during operation.

Process compatibility and practical benefits for production

Conforming to recognised standards and featuring a metric thread form simplifies integration into existing workflows; parts produced with this tap match the expectations of ISO tolerance classes and DIN specifications. The tool's focus on blind-hole performance and material capability up to steels up to 1000 N/mm² makes it a pragmatic choice for general engineering workshops and small-batch industrial production alike. Reduced downtime, predictable maintenance intervals and easier quality assurance are direct outcomes of selecting the correct tool geometry and substrate for the task.
