Tap DIN 352 Form B M4 x 0.7 mm HSS‑Co ISO2 (6H) — TECWERK

The Tap DIN 352 Form B M4 x 0.7 mm HSS‑Co ISO2 (6H) is a single‑cut machine tap designed for producing precise metric through threads in steels up to approximately 900 N/mm², with straight flutes and relieved flank geometry for consistent thread quality

• HSS‑Co for high wear resistance
• Straight flutes for reliable chip evacuation
• ISO2 (6H) tolerance for precise metric threads

Precision where standard conformity matters

This threading tool is manufactured to DIN 352 and delivers the ISO2 (6H) tolerance commonly required in industrial assemblies. The combination of a cobalt‑alloyed high‑speed steel (HSS‑Co) substrate and the Form B specification results in a tool that maintains cutting geometry under repeated use. For procurement and production planning, the standard compliance means predictable fitting behaviour and reduced sorting at inspection — a clear advantage for workshops and small production lines that demand repeatable accuracy.

Engineered performance for common steels

Specified for use in steels up to 900 N/mm², the tap’s material choice and geometry balance toughness and wear resistance. HSS‑Co provides enhanced heat resistance compared with conventional high‑speed steels, which helps during interrupted cuts or when higher cutting speeds are required. The tool is uncoated, allowing for stable performance in lubricated operations and straightforward regrinding when service life is reached — a practical benefit for maintenance budgets and tool life management.

Reliable chip control and thread integrity

The straight flutes and relieved flanks support effective chip evacuation and reduce the risk of thread deformation in through‑hole applications. The incorporated cutting chamfer for through threads minimises initial cutting forces and helps produce clean thread starts, which simplifies assembly and improves torque characteristics of threaded fasteners. For users less familiar with tap geometry: relieved flanks reduce friction along the thread flank, enhancing surface finish and measurement conformity.

Selection and application made straightforward

As a single‑cut (einschnitt) machine tap in Form B, the tool is suited to standard tapping heads and machine spindles; it is intended primarily for through‑hole threads. When matching to a process, consider the M4 x 0.7 mm designation together with the stated material suitability to ensure compatibility with workpiece strength and cutting parameters.
