M55x3 fine thread hand taps
Hand Tap M55x3 DIN 2181/2 HSS is a precision-made tool designed for cutting metric fine-coil threads in structural and alloy steels with strengths up to eight hundred megapascals. High accuracy and stability of the process is ensured by Set Taps Manual M55x3, whose appropriately selected members guarantee a smooth transition from the introduction phase to the finishing phase, minimizing the risk of jamming and unevenness of the outline.
Performance parameters: nominal diameter fifty-five millimeters; stroke three millimeters; outline sixty degrees according to ISO 68-1; hole tolerance class 6H (ISO 965); right-hand direction; straight chip grooves for predictable chip evacuation. HSS high-speed steel in a precision grind maintains edge sharpness and reduces the risk of micro chipping. A two-member arrangement in accordance with DIN 2181/2 - insertion member (I) and finishing member (II) - distributes torsional loads and promotes threading alignment. Recommended drill bit for threading: fifty-two millimeters; lubrication with emulsion or active oil improves surface quality and extends tool life.
- Uniform guidance - a two-stage workflow reduces torsional torque fluctuations and guarantees a stable thread outline.
- Blade durability - ground HSS high-speed steel maintains low micro roughness and resistance to dulling even with intensive use.
- Accuracy of fit - Class 6H ensures a proper fit with Class 6g male threads, eliminating the risk of installation backlash.
- Quality control - geometry and dimensions can be verified with pass/fail gauges, maintaining full compliance with ISO standards.
Meeting the requirements of DIN 2181/2 (execution), ISO 68-1 (metric outline) and ISO 965 (6H tolerance) guarantees full compliance with inspection instruments. In unit and short-run cycles, high dimensional repeatability and thread profile stability are ensured by the M55x3 Hand Thread Set, maintaining quality consistency throughout the machining process.

Frequently asked questions
1. What does the M55x3 set include?
The set consists of two thread cutters - a peeler and a finisher, which, when used in succession, guarantee full thread formation.
2. What pre-drilling for M55x3?
Drill 52 mm (55 mm diameter minus 3 mm pitch) to get the correct filling of the profile in class 6H.
3. What are the advantages of manufacturing with HSS?
HSS high-speed steel provides high durability, wear resistance and stable operation even in demanding conditions.
