M68x2 fine thread hand taps
Hand Tap M68x2 ISO 529/2 6H HSS is designed for making precision metric threads with a diameter of sixty-eight millimeters and a pitch of two millimeters. It works well in machining structural steels, metal alloys and materials with a hardness of up to eight hundred megapascals, ensuring a clean outline and dimensional repeatability in manual and assembly operations.
Technical parameters: nominal diameter 68 mm, pitch 2 mm, thread profile sixty degrees according to ISO 68-1, hole tolerance class 6H according to ISO 965, right-hand direction. Straight chip grooves provide controlled chip evacuation and friction reduction. Made from HSS high speed steel in a precision grind reduces micro-cracking and ensures blade life. A two-part system according to ISO 529/2 - an inserting member (I) and a finishing member (II) - stabilizes the process and balances torsional torque. Recommended drill bit: 66 mm; lubrication with emulsion or active oil improves surface quality and increases edge life.
- Work efficiency - precise guidance and repeatability of machining steps is supported by the M68x2 Hand Tapping Set, which facilitates alignment and profile cleanliness.
- Uniform coil shaping - dividing the work into two stages makes it possible to achieve a uniform thread profile without jamming or deformation.
- High blade life - HSS high speed steel after grinding maintains low surface roughness and reduces edge wear.
- 6H fit accuracy - maintenance of the effective dimension ensures a positive "pass/fail " inspection.
Reference to ISO 529/2, ISO 68-1 and ISO 965 guarantees full compatibility with inspection instruments and stability of coil geometry. In workshop practice, high predictability of results and smooth operation is enabled by Set Taps Manual M68x2, which ensures consistency between thread insertion and finishing phases.

Frequently asked questions
1. What are the advantages of being made of HSS?
HSS high-speed steel provides high durability, wear resistance and stable operation even in demanding conditions.
2. What does the M68x2 set include?
The set consists of two threaders - a peeler and a finisher, which, when used in succession, guarantee full thread formation.
3. What pre-drilling for M68x2?
Drill 66 mm (68 mm diameter minus 2 mm pitch) to get the correct filling of the profile in class 6H.
