Die M56x1.5 left-hand HSS DIN 22 568 – left-hand metric fine thread of medium-to-large diameter
The M56x1.5 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 56 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 required. Compliance with DIN 22 568 and a tolerance class of 6g ensure correct mating with 6H left-hand nuts. This tool is intended for specialist workshops serving the machinery industry, large rotating equipment, and assemblies requiring left-hand threads with enhanced reliability.
Main advantages of the M56x1.5 left-hand fine-thread die
- Left-hand fine thread at a diameter of 56 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 56 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 M56x1.5 left-hand die is a solution for specialist 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 metric fine thread. Due to this combination (left-hand + fine pitch + medium-to-large diameter), threading requires a highly skilled operator, rigid die stocks with long handles of at least 500 mm, and intensive lubrication with products specifically intended for metric fine threads.
Frequently asked questions
Prepare a rod (diameter 55.6-55.65 mm) with a chamfer. Clamp it very securely to eliminate vibration. Turn the die to the left (counterclockwise), making two turns forward, then back off half a turn to the right. For a left-hand metric fine thread of medium-to-large diameter, use a die stock with handles of at least 500 mm and check squareness regularly.
Use threading oils or cooling and lubricating emulsions, applied very generously before starting and every 2-3 turns. A left-hand metric fine thread at a diameter of 56 mm requires intensive lubrication – a pitch of 1.5 mm generates a very large number of chips, requiring a continuous supply of lubricant for smooth operation under substantial cutting forces.
Remember that unscrewing a left-hand thread requires turning to the right. Immediately turn clockwise to safely withdraw the die. At a medium-to-large diameter, problems can be dangerous – clean the flutes very thoroughly and check the rod diameter with a micrometer. Resume with the highest frequency of backing off (every 1.5 turn) and generous fresh lubrication under the supervision of an experienced operator familiar with left-hand threads.
