6mm Machine Tap DIN 371B M6x1 HSS-Co ISO2 (6H), Straight Flute Countersink For Through Holes - TECWERK

Combine the HSS‑Co construction with the straight‑fluted Form B geometry and flank relief to achieve reliable M6×1 threads in steels up to approximately 900 N/mm²; order via Metav Werkzeuge or consult our advisors for application guidance.

TECWERK machine thread tap DIN 371B M6×1 HSS‑Co 6H — straight‑fluted, Form B, for through threads

The TECWERK machine thread tap DIN 371B M6×1 HSS‑Co 6H is a machine tap designed to produce ISO metric threads with precision and repeatability in workshop and light industrial production settings.

• HSS‑Co, Form B, straight‑fluted design
• Flank relief for clean thread finishing
• ISO metric thread M6×1, tolerance field 6H
• Shaft diameter 6 mm for machine holders

Consistent M6×1 threads for demanding components

This machine tap combines a HSS‑Co substrate with a geometry specified to DIN 371B, delivering reproducible results for ISO metric threads. The tolerance field 6H corresponds to a standard internal thread fit and ensures compatibility with mating bolts and components, reducing rework and inspection time. Specified for steels up to ~900 N/mm², the tool is suitable for many common engineering steels used in fixtures, brackets and small assemblies where thread accuracy is critical.

Efficient chip evacuation and secure thread finishes

The straight‑fluted profile promotes reliable chip flow during through‑hole tapping, while the built‑in peel‑cut chamfer (Schälanschnitt) is optimised for through threads to reduce chip congestion and minimise jamming. The flank relief (flanks hinterschliffen) improves cutting action at the thread flanks, producing a clean thread root and flank geometry that requires less post‑processing. Together these features lower cycle times and support consistent surface quality across production runs.

Simple integration and handling in machine setups

A 6 mm shank diameter suits standard collets and quick‑change holders, facilitating rapid tool changes and minimal spindle adjustment. Conformance to DIN 13 Sheet 1 and the ISO metric standard supports interchangeability across tools and fixtures, simplifying inventory and planning. Supplied as a single unit per packaging, the tap is a compact, production‑ready option for workshops seeking a balance of durability and predictable performance.

FAQ

What materials is this tap suitable for?
The TECWERK machine thread tap is specified for use in steels up to approximately 900 N/mm², making it suitable for common engineering steels used in workshops and small‑batch production.

Is the thread tolerance suitable for standard bolts?
Yes; the tap produces an ISO metric thread to tolerance field 6H, which is a standard internal thread tolerance compatible with typical external bolt tolerances.

Can this tap be used in a machine with a 6 mm collet?
The tool has a 6 mm shank diameter and is intended for insertion into standard 6 mm holders and collets used in automatic and manual machine tapping operations.

What is the advantage of the straight‑fluted Form B design?
The straight‑fluted Form B profile improves chip evacuation in through‑hole tapping and, together with the peel‑cut chamfer, reduces the risk of chip build‑up and tap breakage during continuous production.

Does this tap conform to recognised standards?
The tap is manufactured to DIN 371B specifications and produces metric ISO threads in accordance with DIN 13 Sheet 1 and ISO tolerancing conventions.
