M18 left-hand HSS die DIN 22 568 – a reliable tool for medium-sized left-hand threads
Mechanical structures with counter-rotating components require precise left-hand threads with appropriate strength properties. M18 left-hand HSS die manufactured in accordance with DIN 22 568 allows cutting of external M18x2.5 left-hand threads on steel, aluminum, and brass rods. The high-speed steel (HSS) cutting edges ensure a uniform thread profile and a long service life without loss of cutting performance.
Properties of the M18 left-hand die for external threads
- Top-quality high-speed steel (HSS) – efficiently machines materials with tensile strengths up to 800 MPa over many operating cycles
- Durable construction measuring 45 x 18 mm – appropriate proportions ensure stability and reliable torque transmission
- Tolerance 6g according to DIN 22 568 – ensures dimensional conformity with left-hand nuts in accuracy class 6H
- Form B with a lead-in notch – allows axial tool alignment and a controlled start to cutting
- Left-hand geometry (LH) – cutting edges designed to cut left-hand threads through counterclockwise rotation
The M18x2.5 left-hand thread is used in conveyor drive mechanisms, adjustment components in textile machinery, bearing puller screws, and joints between shafts rotating in opposite directions. M18 left-hand HSS die is important equipment for maintenance workshops and facilities manufacturing equipment with left-hand threaded components. Choose a tool ready to handle specialized projects.
Frequently asked questions
Left-hand threads prevent joints from loosening on their own due to vibration or rotation. They are also used in systems with shafts rotating in opposite directions.
Yes, the die stock is selected solely according to the outside diameter of the die. The thread direction does not affect how the tool is secured in the die stock.
The same lubricants are used as for right-hand threads – threading oil or a cooling and lubricating emulsion. The type of lubricant depends on the workpiece material, not the thread direction.
