Die M33x1 HSS DIN 22 568 – ultra-fine threading tool for precision joints

The M33x1 die is a specialized round tool made of high-speed steel (HSS) with a hardness of 64 HRC, combining a diameter of 33 mm with an ultra-fine pitch of 1 mm. This unusual combination produces a thread with exceptional properties – maximum leak tightness, the highest vibration resistance, and the ability to adjust tightening force with extreme precision at medium dimensions. Compliance with DIN 22 568 and a 6g tolerance ensure proper mating with 6H nuts in highly specialized industrial applications. This tool is intended for workshops serving the aerospace industry, precision instrumentation, and structures requiring the highest joint reliability at medium dimensions.

Main advantages of the M33x1 ultra-fine-thread die

  • Ultrafine pitch of 1 mm at a diameter of 33 mm – an exceptionally unusual combination providing extreme joint leak tightness and maximum resistance to loosening under high vibration
  • Diameter of 33 mm for specialized applications – a size found in precision machinery, measuring instruments, and equipment requiring the highest joint reliability
  • HSS steel hardness of 64 HRC – high hardness enables extended cutting of ultrafine-pitch threads in steels up to 800 MPa despite the extremely high number of thread turns
  • Tolerance class 6g according to ISO – medium accuracy with controlled clearance ensures a proper fit in precision mechanisms requiring stability
  • Solid round construction – one-piece construction eliminates cumulative errors that are critical with an ultra-fine pitch and ensures maximum repeatability

The M33x1 die is a highly specialized tool for workshops serving the aerospace industry, precision instrumentation, medical equipment, and critical structures where safety and reliability requirements are the highest. It is suitable for cutting threads on critical components requiring maximum leak tightness and vibration resistance. Due to the unusual combination, threading requires a highly qualified operator, very stable workholding, and intensive lubrication with products specifically designed for fine threads.

Frequently asked questions

Prepare a rod (diameter 32.85-32.9 mm) with a carefully chamfered end. Clamp it very securely to eliminate any vibration. Keep the die strictly perpendicular, making one full turn forward, then reversing half a turn to break the chips. With an ultra-fine pitch, check perpendicularity very frequently and lubricate every turn.

An ultra-fine pitch requires the most intensive lubrication. Use high-quality threading oils, applied generously before each turn. With a diameter of 33 mm and a pitch of 1 mm, a very large number of chips is generated – lubricant must be present at all times to ensure smooth operation and protect the cutting edges.

An ultra-fine pitch generates an extremely large number of chips. At the slightest increase in resistance, immediately unscrew the die completely and clean the flutes very thoroughly with compressed air. Check the rod diameter with a micrometer (tolerances are very tight). Resume with the highest possible reversing frequency (every 0.75-1 turns) and a generous application of fresh lubricant.
