Die M3x0.25 HSS DIN 22 568 – ultraprecision tool for miniature threads
The M3x0.25 die is a highly precise round tool made of high-speed steel (HSS) with a hardness of 64 HRC, designed for cutting external metric threads with a minimum diameter of 3 mm and an ultrafine pitch of 0.25 mm. Threads of such extremely small dimensions require the highest manufacturing precision and are used in precision engineering, electronics, optics, and measuring instruments. Compliance with DIN 22 568 and a tolerance class of 6g ensure a proper fit with 6H nuts in applications requiring absolute dimensional accuracy. This tool is intended for the most specialized precision workshops and toolrooms producing miniature components to the most demanding requirements.
Key benefits of the M3x0.25 precision die
- Ultraminiature thread with a pitch of 0.25 mm – the extremely fine pitch ensures the highest joint precision and allows ultraprecise tightening torque adjustment in applications requiring absolute accuracy
- Diameter of 3 mm for the smallest components – the size makes the tool suitable for ultraminiature rods, studs, and pins in electronics, precision optics, and microinstrumentation
- HSS steel hardness of 64 HRC – maintains sharpness despite the extremely small cutting edge dimensions when cutting threads in steels, aluminum, and brass
- Tolerance class 6g according to ISO – standard accuracy grade with controlled clearance ensures a proper fit in ultraprecision mechanisms requiring the highest repeatability
- Solid round construction – the unsegmented construction eliminates dimensional errors that are absolutely critical at ultraminiature diameters and ensures stability during the most delicate operations
The M3x0.25 die is a tool for the most specialized workshops involved in precision engineering of the highest caliber and the manufacture of measuring instruments, precision optics, and microelectronics. It excels at cutting threads on ultraminiature adjustment studs, microscopic pins, and components requiring absolute dimensional accuracy. Due to the extreme dimensions and ultrafine pitch, threading requires exceptional care – perfect clamping under a microscope, perfect perpendicular alignment, ultraprecise lubrication, and an operator with the highest qualifications and experience in machining microcomponents.
Frequently asked questions
The recommended blank diameter ranges from 2.95 to 2.97 mm. With such an ultraminiature diameter and extremely fine pitch, precision in rod preparation is absolutely critical – even a deviation of 0.05 mm can prevent proper cutting.
The extreme challenges include exceptionally delicate cutting edges that are easily damaged by even slightly excessive pressure, the need to work under a magnifier or microscope to check perpendicular alignment, the risk of tool breakage from the slightest error, and the requirement for ultraprecise lubrication with specialized products.
This thread is used in ultraprecision measuring instruments (micrometric indicators), optics of the highest caliber (lens adjustment mechanisms), microelectronics (precision sensor housings), medicine (surgical instruments), and wherever ultraminiature threaded joints with absolute accuracy are required.
