Die M48x1.5 left-hand HSS DIN 22 568 – left-hand metric fine thread of medium-to-large diameter
The M48x1.5 left-hand die is a specialized round tool made of high-speed steel (HSS) with a hardness of 64 HRC, combining a medium-to-large diameter of 48 mm with a left-hand metric fine thread with a pitch of 1.5 mm. This combination is used in medium and large rotating machinery where the direction of rotation during operation requires a left-hand thread, while increased vibration resistance from the fine pitch is also required. Compliance with DIN 22 568 and a tolerance of 6g ensure proper mating with left-hand 6H nuts. This tool is intended for specialized workshops serving the machinery industry, rotating equipment, and structures requiring left-hand threads with increased reliability at medium-to-large dimensions.
Key benefits of the M48x1.5 left-hand fine-thread die
- Left-hand fine thread at a diameter of 48 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 48 mm for medium-to-large machinery – a size found in gearboxes, large grinding machines, and industrial machinery requiring a left-hand thread with additional properties
- HSS steel hardness of 64 HRC – ensures long service life when cutting left-hand metric fine threads in structural steels up to 800 MPa
- Tolerance class 6g according to ISO – a medium accuracy grade with controlled clearance ensures a proper fit with left-hand nuts at medium-to-large dimensions
- Solid round construction – one-piece construction provides the rigidity required for cutting left-hand threads with a fine pitch at medium-to-large diameters
The M48x1.5 left-hand die is a solution for specialized workshops servicing medium and large rotating machinery, industrial gearboxes, grinding machines, and equipment where the direction of rotation requires a left-hand thread and operating conditions also require a fine pitch. Due to its specific characteristics (left-hand + fine pitch + medium-to-large diameter), threading requires highly qualified operators, rigid holders, and intensive lubrication.
Frequently asked questions
Prepare a rod (diameter 47.6-47.65 mm) with a chamfered end. Clamp it very securely to eliminate vibration. Rotate the die counterclockwise (to the left), making two turns forward, then reversing half a turn clockwise. When cutting a left-hand metric fine thread of medium-to-large diameter, check perpendicularity frequently.
Use threading oils or cooling and lubricating emulsions, applied generously before starting and every 2-3 turns. A left-hand metric fine thread with a diameter of 48 mm requires intensive lubrication – a pitch of 1.5 mm generates a large number of chips, requiring lubricant to be continuously present for smooth operation.
Remember that unscrewing a left-hand thread requires turning clockwise. Immediately rotate clockwise (to the right) to withdraw the die. Clean the flutes very thoroughly and check the rod diameter with a micrometer. Resume with more intensive lubrication and more frequent reversing – for a left-hand metric fine thread, every 1.5 turns instead of every 2.
