M22x2.5mm Hand Tap Set HSS ISO2 (6H) 3-Pc, Right-Hand - TECWERK

High-speed steel construction and an ISO2 (6H) tolerance deliver durable, accurate threads while the three-stage configuration reduces tap breakage and improves cycle consistency; order the set directly via Metav Werkzeuge or ask the consultants for specification support.

Hand tap set M22 x 2.5 mm HSS ISO2 (6H) – 3-piece by TECWERK

The Hand tap set M22 x 2.5 mm is a manual three-piece tap set for producing metric ISO threads to DIN standards, suitable for through and blind holes in steels up to 900 N/mm².

• HSS high-speed steel construction
• Metric ISO thread to DIN 13 sheet 1
• ISO2 (6H) tolerance for precise fits
• Three-piece set: rough, medium, finish

Precision and durability for repeatable threads

The Hand tap set M22 x 2.5 mm HSS ISO2 (6H) 3-piece is manufactured from HSS, providing a balance of toughness and wear resistance for robust shop-floor use. The taps meet the DIN 13 metric thread geometry and the ISO2 (6H) tolerance band, which ensures consistent thread fit and interchangeability with standard fasteners. For machinists, this means fewer rejects and more predictable assembly outcomes when working with common engineering steels. The specification for use in steels up to 900 N/mm² gives a clear limit for material selection and helps to prevent premature tool failure in tougher alloys.

Faster, safer threading with a three-stage approach

A set comprising the rough, intermediate and finish taps reduces cutting forces at each stage and minimises the risk of tap breakage — a frequent cause of downtime in manual tapping operations. The staged process improves chip evacuation and leads to a cleaner flank surface on the finished thread, translating into higher thread quality and less rework. The right-hand cutting geometry suits standard hand-tapping procedures and the defined sequence enhances process reliability, particularly where a mixture of through and blind holes must be handled with the same tooling.

Workshop compatibility and practical handling

With a shank Ø 18 mm the set fits most standard manual holders and tap wrenches, easing integration into existing workstations without further adaptation. The designation for both through and blind holes clarifies application scope, while the right-hand cut follows conventional machining practice. For maintenance, the HSS material can be re-sharpened in specialised service centres when life is exhausted, extending the economical service life of the set. For selection or workplace integration advice, Metav’s technical team is available to explain fitment and process implications.

Understanding standards and avoiding common errors

Adherence to metric thread standards reduces assembly issues and simplifies procurement of mating components. The mention of DIN 13 sheet 1 indicates the thread profile and pitch form, while the ISO2 (6H) tolerance denotes a standard internal thread class for general industrial use. When tapping, correct lubrication and the recommended tap sequence should be followed to reduce wear and prevent chipping of the cutting edges. Where material strength approaches the upper limit of 900 N/mm², consider appropriate coolant and conservative feed to maintain tool life.

FAQ

What materials are suitable for these taps? The Hand tap set M22 x 2.5 mm HSS ISO2 (6H) 3-piece by TECWERK is rated for steels up to 900 N/mm² and is optimised for standard engineering steels within that strength range.

Is the set suitable for blind holes as well as through holes? Yes. The three-piece configuration is specified for both through and blind holes, enabling controlled chip formation and safer tapping in blind bores.

What does ISO2 (6H) mean for thread fit? ISO2 (6H) denotes the internal thread tolerance class that provides a standard medium fit appropriate for general industrial assemblies, ensuring compatibility with common external fasteners.

Which standards define the thread geometry of the set? Thread geometry follows the metric specifications referenced as DIN 13 sheet 1, and the taps conform to the DIN 352 designation for hand taps.

What is included in the set and how does it improve process reliability? The set contains three taps — rough, intermediate and finish — which together reduce cutting loads, improve chip control and lower the risk of tap fracture compared with single-pass tapping
