Die M24x1.5 left-hand HSS DIN 22 568 – left-hand metric fine thread for precision machines
The M24x1.5 left-hand die is a specialized round tool made of high-speed steel (HSS) with a hardness of 64 HRC, combining a diameter of 24 mm with a left-hand metric fine thread with a pitch of 1.5 mm. A left-hand thread is cut in the opposite direction to a standard thread, preventing self-unscrewing in rotating equipment, while the fine pitch further increases vibration resistance. Compliance with DIN 22 568 and a tolerance of 6g ensure a proper fit with left-hand 6H nuts. This tool is used in precision machines, industrial equipment, and wherever components rotate clockwise during operation and require maximum protection against loosening while maintaining high precision.
Key benefits of the M24x1.5 left-hand fine-thread die
- Left-hand metric fine thread with a pitch of 1.5 mm – combining a left-hand direction with a fine pitch provides dual protection: mechanical protection against unscrewing and design-based protection against vibration-induced loosening
- Diameter of 24 mm for precision applications – a size commonly found in rotating machinery, industrial equipment, and structures requiring a left-hand thread with increased reliability
- HSS with a hardness of 64 HRC – provides long service life when cutting left-hand metric fine threads in structural steels up to 800 MPa, aluminum, and brass
- 6g tolerance according to ISO – a standard accuracy grade with controlled clearance ensures a proper fit with left-hand nuts in precision mechanisms
- Solid round construction – non-segmented construction eliminates dimensional errors and ensures stability when cutting left-hand metric fine threads
The M24x1.5 left-hand die is a tool for machine shops specializing in rotating machinery, power tools, and industrial equipment requiring a left-hand thread with the additional benefits of a fine pitch. It is particularly useful for cutting threads on shafts, pins, and studs where a standard right-hand thread could loosen and vibration resistance is also required. The combination of a left-hand thread and a fine pitch requires increased operator attention during the process.
Frequently asked questions
Prepare the rod (diameter 23.6-23.65 mm) with a chamfer. Position the die squarely and turn counterclockwise (to the left), making two forward turns, then back off half a turn clockwise. When cutting a left-hand metric fine thread, pay particular attention to squareness and lubricate every 2-3 turns to ensure quality.
For structural steels, use threading oils applied before starting and replenished every 3 turns. Left-hand metric fine threading requires intensive lubrication – at a pitch of 1.5 mm, a large amount of chips is generated. The left-hand direction does not affect lubrication requirements; pitch and diameter determine them.
For a left-hand thread, the backing-off direction is reversed – turn to the right (clockwise). Stop immediately if binding occurs, back off completely, and clean the flutes with a brush or compressed air. Verify the rod diameter with a micrometer. Resume with generous lubrication and more frequent backing off – for a left-hand metric fine thread, every 1.5 turn instead of every 2.
