M68x4 fine thread hand taps
Hand Tap M68x4 DIN 2181/2 6H HSS is a precision tool designed for making internal metric threads with a diameter of sixty-eight millimeters and a pitch of four millimeters. In workshop applications, high accuracy and cleanliness of the thread surface is provided by the M68x4 Hand Tapping Set, designed in accordance with DIN and ISO standards for manual and assembly work.
The technical parameters include a nominal diameter of 68 mm, a stroke of 4 mm, an outline of sixty degrees according to ISO 68-1, a bore tolerance of class 6H (ISO 965), and a right-hand design. The straight chip grooves ensure controlled chip evacuation and stable workflow. The material - HSS high-speed steel in a ground version - guarantees wear resistance and maintains edge sharpness even at higher torsional torque. The two-piece arrangement according to DIN 2181/2 (introduction I and finishing II) balances loads and promotes machining alignment. Recommended drill bit: 66.0 mm; use of emulsion or active oil improves surface structure and extends blade life.
- Process control - gradual torque distribution stabilizes work and reduces the risk of seizure.
- Durability and precision - high-hardness high-speed steel maintains sharp edges and a clean coil outline.
- 6H fit accuracy - maintaining the effective dimension guarantees a positive pass/fail test.
- Repeatability of results - ergonomic operation and consistency of machining phases supported by Set Taps Manual M68x4 translate into uniform results and safe guidance.
Meeting the requirements of DIN 2181/2 (execution), ISO 68-1 (outline geometry) and ISO 965 (6H tolerance) guarantees full compatibility with the measuring equipment. The solution developed by enables reproducible results in unit and short-run production, combining durability with dimensional precision.
