Round Die DIN 223 (DIN EN 22568) HSSE VAP - M 3 x 0.5

1. Preparation: Turn the round bar or shaft down to the nominal thread diameter (here 3.0 mm). Lightly chamfer the edges to facilitate the initial cut. Fix the workpiece securely in the vise or clamping device.
2. Clamping: Insert the round die into the appropriate die stock and secure it firmly with the clamping screws (Form B).
3. Lubrication: Before starting, generously apply cutting oil to the die and the start of the workpiece. The VAP surface helps to retain the oil optimally.
4. Starting the Cut: Place the die perpendicularly to the workpiece axis. Press lightly and turn the die stock clockwise evenly. The chamfer assists with centered cutting.
5. Cutting Process: Turn the die continuously clockwise to cut the thread, ensuring a constant supply of lubricant.
6. Final Check: Once the desired thread has been cut, carefully turn the die off completely. Check the thread using a suitable thread ring gauge or nut.

The information applies to the quality and application areas of the HSSE VAP die presented here.

Q1: What does the designation HSSE VAP mean?

A1: HSSE stands for High-Speed Steel with Cobalt, offering higher hardness and hot hardness than HSS. VAP (Vaporized) is a surface treatment that improves the adhesion of cutting oil, thereby extending tool life, especially for tough and stainless materials.

Q2: Which materials is this die particularly suitable for?

A2: Due to the HSSE VAP material, it is ideal for demanding materials such as stainless steels, high-strength alloyed steels up to 1200 N/mm², as well as cast aluminum and spheroidal graphite cast iron (GGG).

Q3: What is the advantage of the closed Form B?

A3: The closed form (Form B) is very stable. It is clamped in the die stock with an adjusting screw and is particularly suitable for machine use or for manual applications where high stability is required.

Q4: What does the tolerance 6g indicate?

A4: The 6g tolerance is the common standard tolerance for external threads. It ensures a normal, clearance-free fit to an internal thread with a 6H tolerance (the common standard for internal threads).

Q5: Can I use this die without cutting oil?

A5: For optimal results, maximum tool life, and a clean cut, especially with stainless or tough materials, the use of high-quality cutting oil is strongly recommended. The VAP treatment further supports the effect of the cutting oil.
