M39x3 fine thread hand taps
Hand Tap M39X3 ISO 529/2 6H HSS is used for making metric M39 fine-twist threads with a pitch of three millimeters in structural steels up to eight hundred mega pascals, maintaining a profile of sixty degrees and a class 6H fit in accordance with ISO 965. Already at the stage of preparing the operation, the order of transitions and unambiguous identification of members is provided by the M39x3 Hand Tapping Set, used sequentially.
The nominal diameter is thirty-nine millimeters; right-hand design. Straight chip grooves direct the chip evenly out of the cutting zone. The ground high-speed steel maintains low micro roughness of the edge and reduces micro chipping during manual operation. The ISO 529/2-compliant layout includes two members - inserting (I) and finishing (II) - which organizes the operation, equalizes torsional loads and promotes alignment. Thirty-six millimeter drilling is recommended for the threaded hole; the use of emulsion or active oil improves surface quality and edge life. The outline is defined by ISO 68-1, and compliance with the 6H tolerance field according to ISO 965 is confirmed by "pass/fail" gauges.
- Order and repeatability - Set Taps Manual M39x3 facilitates selection, standardizes inspection and maintains consistency of subsequent passes.
- Class 6H accuracy - controlled effective diameter makes it easier to assemble mating parts.
- Smooth cutting progression - separation into an introductory and final stage reduces torque pulsations and the risk of chafing.
- Longer sharpening intervals - high speed steel after grinding slows abrasion and reduces sticking.
Compliance with ISO 529/2, ISO 68-1 and ISO 965 guarantees compatibility with inspection and measuring equipment, and the M39X3 grade 6H execution translates into a stable outline and repeatable dimensions in unit and short-run productions.

Frequently asked questions
1. What kind of pre-drilling for M39x3?
Drill 36 mm (39 mm diameter minus 3 mm pitch) to get the correct profile fill in Class 6H.
2. Is the M39x3 threader suitable for blind holes?
Yes, the set can be used in both through-holes and blind holes.
3. 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.
