M3–M20 HSSG Hand Tap Set Double-Ended With Roughing And Finishing Cuts, ISO 6H - VÖLKEL GmbH

Take advantage of precision ground HSS taps and ISO2 (6H) tolerance to produce consistent metric threads in both through and blind holes. The two‑stage design with pilot and finishing cutters reduces rework and extends tool life; order the set directly via Metav Werkzeuge or request advice from our consultants.

HexTap Hand Tap Set M3–M20, HSS‑G, ISO2 (6H) — VÖLKEL

HexTap Hand Tap Set M3–M20 delivers metric ISO threads for general workshop and maintenance use, combining ground HSS cutting edges with a two‑stage tap geometry for reliable thread form and reduced tapping forces.

• HSS‑G ground high‑speed steel taps
• Two-sided taps with pilot and finish cutters
• Metric ISO threads to DIN 13, tolerance ISO2

Consistent thread quality from ground HSS material

The HexTap hand tap set is engineered with HSS‑G cutting material and a two‑step geometry to guarantee a defined thread profile under varied workshop conditions. Ground high‑speed steel provides a sharp, wear‑resistant cutting edge that maintains form over multiple uses. Compliance with DIN 13 and the ISO2 (6H) tolerance field ensures that internal threads match standard bolts and components, supporting interchangeability and reducing assembly issues. The kit is intended for reliably producing metric threads in typical engineering materials up to approximately 900 N/mm² tensile strength.

Two‑stage cutting for efficient production and reduced rework

A sequence of pre‑cut and finish‑cut flutes is built into the design to split material removal into controlled steps: the pre‑cut forms the initial thread, while the finish‑cut completes the profile to standard tolerance. This staged approach lowers cutting forces, reduces torque peaks and helps avoid tap breakage in hand operations. The result is fewer scrapped parts, less rework and a smoother tapping process for both through and blind holes. For maintenance and light production environments, this means faster job turnaround with consistent results.

Broad size range for common workshop applications

Covering sizes M3–M20, the set addresses a wide span of fastening needs encountered in mechanical workshops, toolrooms and service departments. The taps are suitable for unalloyed and low‑alloy steels and other readily machinable materials, delivering a practical solution when metric ISO threads are required on assemblies or repairs. The range minimises the need to source individual taps for each common size and supports standardisation of in‑house tooling.

Practical handling and expected outcomes in everyday use

Designed as a hand tap set, the geometry balances ease of start, cutting reliability and thread accuracy. Use in combination with appropriate tapping practice — correct alignment and steady feed — yields threads that meet the declared tolerance class and provide secure fastenings. The two‑step design also helps users new to manual tapping achieve better results sooner, while experienced operatives will appreciate the consistent thread form and reduced likelihood of tap wear or failure.

FAQ

What materials can be machined with this tap set?
The HexTap hand tap set from VÖLKEL (SKU 4000867038NW) is specified for unalloyed and low‑alloy steels and other well machinable materials, up to roughly 900 N/mm² tensile strength.

Is the set suitable for blind holes as well as through holes?
Yes, the two‑stage geometry of the VÖLKEL HexTap hand tap set is designed for both through and blind holes, allowing controlled chip removal and accurate finishing.

Which thread standard and tolerance does the kit meet?
Threads are formed to metric DIN 13 with tolerance field ISO2 (6H); the set also addresses Whitworth pipe threads G in accordance with DIN ISO 228 where applicable.

How does the two‑stage tap design benefit everyday workshop use?
Splitting cutting into pre‑cut and finish‑cut steps reduces torque and wear during tapping, delivering more consistent threads and fewer broken taps when using the HexTap hand tap set.

Can the taps be used for stainless or hardened steels?
The VÖLKEL HexTap hand tap set is specified for good machinable materials and steels up to about 900 N/mm²; for stainless or hardened steels consult material‑specific tooling recommendations.
