M39 HSS DIN 22 568 die – durable construction for threading heavy components
Cutting threads on large-diameter bars requires a tool with adequate strength. Die M39 HSS meets the requirements of DIN 22 568 and is designed to cut M39x4 external threads in structural steels, free-cutting steels, and nonferrous metals. Its high-speed steel (HSS) construction keeps the cutting edges fully functional over a long service life.
Characteristics of the M39 die for external threads
- HSS tool material with increased hardness – enables effective threading of materials with a tensile strength of up to 800 MPa
- Heavy-duty dimensions of 75 x 30 mm – increased outside diameter and thickness provide resistance to deformation under substantial cutting forces
- Thread tolerance 6g in accordance with DIN 22 568 – ensures a proper fit with nuts and components in tolerance class 6H
- Form B construction with a precut slot – facilitates correct positioning on the material and efficient chip removal
- Suitable for manual and machine operation – works with die stocks and can be used on conventional lathes
The M39x4 thread is used in heavy industrial machinery, anchors and foundation bolts, gearbox shafts, and load-bearing structural components. Die M39 HSS provides reliable tooling for manufacturing plants and technical service centers that machine large workpieces. Invest in a tool that meets the toughest threading challenges.
Frequently asked questions
Start by measuring the bar diameter with a caliper to an accuracy of 0.05 mm. Using thread charts or catalog information, select a die with the appropriate size and thread pitch, along with the recommended starting material diameter.
This marking confirms compliance with the standard governing the specifications of round dies for ISO metric threads. The standard defines tool geometry, overall dimensions, thread tolerance (usually 6g), and construction type – form B indicates a closed version with a precut slot.
Mount the tool only in a suitable die stock and keep it perpendicular to the bar axis. Remember to apply even pressure and use a lubricant. Avoid mounting it in improvised holders – incorrect clamping causes the die to crack.
