Produktübersicht
Tackle the toughest industrial environments with our Metric Round (RD) DIN 20400 laydown threading inserts. Unlike the standard DIN 405 (which handles finer pitches), the DIN 20400 series is a heavy-duty 30° round thread primarily used in mining machinery and large valves where threads are subject to high impact or debris contamination.
Diese Hartmetall-Gewindebohrer feature a “Full Profile” design that cuts the rounded groove and tops the rounded crest (R0.22104P / R0.23851P) in a single operation. This smooth, rounded geometry is easy to clean and highly resistant to damage compared to sharp V-threads.
Wichtigste Merkmale und Vorteile
- Impact Resistance: The rounded profile eliminates stress concentrators, making it ideal for heavy dynamic loads.
- Heavy Capacity: Während ein Standard 16er-Gewindeeinsatz handles fine work, these large I.C. inserts (1/2″ and 5/8″ U-Type) are built for coarse pitches up to 8.0mm.
- Präzisionsform: Maintains the strict radius tolerances required by DIN 20400 to ensure smooth assembly even in dirty conditions.
-
Richtungsoptionen: Wir bieten umfassende Lösungen, darunter Linksgewindeeinsatz models (e.g., 22IL 5.0 RD) often required for rotational equipment.

Bearbeitungsrichtlinien
- DIN Standard: Ensure you are cutting DIN 20400. Do not confuse this with DIN 405 (which uses smaller inserts like the 16er threading insert for finer pitches).
-
Werkzeughalter:
-
22ER/IR inserts fit standard size 22 threading inserts for lathe holders.
-
27U inserts require specialized U-Type holders.
-
- Cutting Force: The large contact area of a round thread generates significant cutting pressure. Ensure rigid clamping and use multiple passes to achieve the full depth.
