TECWERK Hand tap set DIN 352, M2 x 0.4 mm – HSS, ISO2 (6H), 3-piece

The TECWERK hand tap set designed for precise metric M2 x 0.4 threads, suitable for through and blind holes in workshop and industrial maintenance.

• HSS for robust cutting performance
• Metric ISO thread M2 x 0.4 mm (DIN 352)
• ISO2 (6H) tolerance for interchangeability
• Three-piece set: taper, intermediate, finishing

Consistent metric threads with industrial tolerances

The set delivers accurate metric threads based on DIN 352 and the ISO2 (6H) tolerance band, ensuring reproducible results for small-thread production and repair work. The progressive three-step system—taper, intermediate and finishing cutter—reduces cutting forces at each stage, which leads to clean flank geometry and fewer rejected parts. For production environments where thread interchangeability and assembly reliability matter, this approach minimises rework and secures component fit in serial assemblies and precision fixtures.

Material suitability and durability for workshop use

Manufactured from HSS, the taps are engineered for durability when machining common workshop alloys; the specification notes suitability for steels up to approx. 900 N/mm², making the set appropriate for many maintenance and fabrication tasks. The 2.8 mm shank provides stable seating in tap wrenches and holders, while the right-hand cutting geometry optimises chip formation during manual tapping. The chosen cutting material and geometry balance wear resistance and edge sharpness so that thread quality is retained over repeated use in day-to-day workshop operations.

Workflow efficiency and application flexibility

Presented as a compact three-piece set, the tools support an efficient workflow: the taper cutter establishes the thread lead, the intermediate cutter increases thread depth with controlled cutting, and the finishing cutter achieves final tolerance and surface finish. This sequence is particularly beneficial for blind holes where progressive material removal reduces breakout and tool stress. The combination of metric standardisation and practical set design makes the kit well suited to electronics, instrument making and general mechanical repair where small, reliable threads are required.

FAQ

What materials can be machined reliably with this tap set?
The TECWERK hand tap set is specified for steels up to approx. 900 N/mm² and is suitable for typical workshop materials used in small-thread applications.

What is included in the three-piece set?
The set comprises a taper (lead) cutter, an intermediate cutter and a finishing cutter to achieve final thread depth and tolerance.

Is the tolerance adequate for interchangeable assemblies?
Yes, the ISO2 (6H) tolerance band provides consistent fits for standardised metric assemblies and simplifies component replacement.

Can this set be used for blind-hole tapping?
The set is designed for both through and blind holes; the progressive cutters reduce breakout and help control chip evacuation in blind threads.

Which standard governs the thread form and dimensions?
Thread geometry and dimensions are referenced to DIN 352 for small metric hand taps.
