M28x2 fine pitch hand taps
Hand Tap M28x2 DIN 2181/2 6H HSS is designed for cutting precision M28 metric threads with a pitch of two millimeters in structural steels, stainless steels and non-ferrous metals. The design based on DIN 2181/2 standards guarantees high outline accuracy and dimensional repeatability in workshop applications and short-run production.
Performance parameters: nominal diameter twenty-eight millimeters; stroke two millimeters; profile sixty degrees according to ISO 68-1; bore tolerance class 6H (ISO 965); right-hand direction; straight chip grooves allow even chip removal. HSS high-speed steel in ground version guarantees long life and resistance to micro-chipping. The two-piece design according to DIN 2181/2 - introducer (I) and finisher (II) - ensures even load distribution and precise alignment. In machining practice, the stability and smoothness of the process is supported by the M28x2 Hand Tapping Set, which allows for the maintenance of an exact fit and high-quality surface finish.
- Stable guidance - even distribution of torsional torque between members ensures smooth machining and eliminates the risk of jamming.
- Wear resistance - high speed steel in a precision grind ensures long life and retains edge sharpness.
- Class 6H fit - maintenance of nominal dimensions makes it possible to work with Class 6g mandrels without mounting clearances.
- Repeatable accuracy - precise geometry and optimum chip evacuation, which is supported by Set Taps M28x2 Manuals, ensure high thread quality and a stable profile over the entire working range.
Meeting the requirements of DIN 2181/2 (design), ISO 68-1 (metric outline) and ISO 965 (6H tolerance) guarantees full compatibility with inspection instruments and dimensional stability. In unit cycles and precision assemblies, the repeatability of the profile and the durability of the tool in long-term operation are maintained.

Frequently asked questions
1. What does set Taps M28x2 contain?
The set consists of two thread cutters - a peeler and a finisher, which, when used consecutively, guarantee full thread formation.
2. What pre-drilled hole should I drill for M28x2?
Drill 26.0 mm (28 mm nominal minus 2 mm pitch) to get the correct filling of the profile at grade 6H.
3. What holes and materials is M28x2 HSS suitable for?
It works well in through-holes and blind holes (with bottom stock for the nut). Recommended materials: structural and automatic steels up to 800 MPa, cast iron, brass, aluminum; for stainless and hard-to-machine steels, the HSS-E/HSSE-PM version with intensive lubrication is preferred.
