Die M50x1.5 left-hand HSS DIN 22 568 – left-hand metric fine thread of medium-to-large diameter
The M50x1.5 left-hand die is a highly specialized round tool made of high-speed steel (HSS) with a hardness of 64 HRC, combining a medium-to-large diameter of 50 mm with a left-hand metric fine thread with a pitch of 1.5 mm. This combination is used in medium-to-large rotating machinery where the direction of rotation during operation requires a left-hand thread, while enhanced vibration resistance provided by the fine pitch is also needed. Compliance with DIN 22 568 and the 6g tolerance ensure proper mating with 6H left-hand nuts. This tool is intended for specialized workshops servicing medium-to-large machinery, rotating equipment, and assemblies requiring left-hand threads with enhanced reliability.
Why choose the M50x1.5 left-hand metric fine thread die
- Left-hand fine thread at a diameter of 50 mm – combining a left-hand thread with a fine pitch provides dual protection: mechanical protection against unscrewing and design-based protection against vibration-induced loosening in medium-to-large sizes
- Diameter of 50 mm for medium-to-large machinery – a size used in large gearboxes, large grinding machines, and industrial machinery requiring a left-hand thread with additional properties
- Fine pitch of 1.5 mm – increases the load-bearing area of the joint and improves resistance to vibrational loads in large rotating equipment exposed to vibration
- HSS steel hardness of 64 HRC – ensures long tool life when cutting left-hand metric fine threads in structural steels up to 800 MPa at medium-to-large diameters
- Solid round construction – one-piece construction provides the maximum rigidity required for cutting left-hand threads with a fine pitch at medium-to-large diameters
The M50x1.5 left-hand die is a solution for specialized workshops servicing medium-to-large rotating machinery, industrial gearboxes, large grinding machines, and equipment where the direction of rotation requires a left-hand thread and operating conditions additionally require a fine thread for maximum reliability. Due to the specific combination (left-hand + fine thread + medium-to-large diameter), threading requires a mechanical drive or at least rigid die stocks with long handles measuring at least 500 mm, as well as intensive lubrication.
Frequently asked questions
The tool is designed for cutting left-hand threads on large spindles, drive shafts, and gearbox components that rotate clockwise. Combining the left-hand direction with an ultra-fine pitch of 1.5 mm ensures maximum resistance to loosening and micrometric adjustment accuracy in large structural components.
The M50x1.5 left-hand version has the opposite thread direction and a pitch of 1.5 mm instead of the standard 5 mm. This more than threefold difference in pitch, together with the left-hand direction, provides exceptional joint stability and adjustment accuracy comparable to micrometer systems.
Rotate the tool counterclockwise, using a generous amount of lubricant. After each turn, back the die off clockwise by half a turn to remove chips. Due to the substantial diameter and fine pitch, thread cutting requires patience.
