Hand tap set DIN 352 M20 x2.5 mm HSS ISO2 (6H) – TECWERK

The Hand tap set DIN 352 M20 x2.5 mm HSS ISO2 (6H) is a workshop-ready metric tapping set designed for cutting ISO threads in steel components, suitable for both through and blind holes in medium-strength steels

• HSS material for reliable cutting performance
• Metric ISO threads to DIN 13, tolerance ISO2 (6H)
• For through and blind holes in steels up to 900 N/mm²
• Includes taper, plug and bottoming taps

Precision threading for demanding workshop tasks

The set delivers consistently accurate M20 x2.5 threads thanks to conformity with DIN 13 and the tight ISO2 (6H) tolerance band, which together ensure interchangeability and reliable assembly in production and maintenance jobs. Manufactured in HSS, the taps retain cutting geometry under repeated use, which reduces rework and supports predictable component fit. For workshops that produce or repair metric-threaded parts, this combination of standards and material provides a clear advantage in repeatable quality and reduced scrap rates.

Design and durability that keep production running

Each tap is supplied as a sequence of taper, intermediate and finishing cutters—often described as taper, middle and finishing tap—so that threads are formed progressively to minimise chip loads and avoid workpiece damage. The tools are forged with a 16 mm shank for secure clamping and stable hand operation, while the right-hand cutting geometry suits standard threading direction. Rated for steels up to 900 N/mm², the set provides a robust solution for general engineering steels and common workshop alloys, helping to lower downtime and extend tool life through controlled chip evacuation.

Easier selection and application for everyday workflows

The three-piece arrangement of starter, intermediate and finish taps simplifies process planning: roughing with the taper cutter, intermediate sizing, and finalising with the bottoming tap. This approach reduces the likelihood of tap breakage and improves thread quality in both through and blind holes, even when chip removal is restricted. Clear specification to ISO2 (6H) makes verification straightforward with standard gauges, and the metric designation means the set integrates seamlessly into existing workshop tool assortments without the need for conversions or special fixturing.

FAQ

What materials are suitable for these taps?
The TECWERK hand tap set is specified for steels up to approximately 900 N/mm² and is suitable for common engineering steels as noted in the product data.

Does the set include all tap stages for safe thread forming?
Yes, the kit contains taper, middle and finishing taps to progress the thread form safely from start to finish and reduce tap stress.

Is the tolerance suitable for serial production?
The taps are manufactured to ISO2 (6H) tolerance and DIN 13 guidance, making them appropriate where consistent interchangeability is required.

Can these taps be used in blind holes?
The set is designed for both through and blind holes; using the taper and middle taps first helps manage chip evacuation in blind applications.

What is the item number for ordering?
The SKU for ordering is 2000867121NW and the product is listed as the TECWERK hand tap set DIN 352 M20 x2.5 mm HSS ISO2 (6H).
