VÖLKEL Round Die DIN 223 (DIN EN 22568) HSS - BSC 5/16 x 26

The VÖLKEL round die according to DIN 223 (DIN EN 22568) is manufactured from HSS (High-Speed Steel) and designed for cutting BSC bicycle threads according to BS 811. The British Standard Cycle thread is widely used in bicycle components, providing reliable and precise external threads. With its robust design, this die is ideal for general use in machinable materials up to 800 N/mm², particularly unalloyed and low alloy steels.

Applications and Benefits
  • Thread type: BSC bicycle thread (BS 811), used in bike parts.
  • Perfect for general workshop use.
  • Suitable for materials up to 800 N/mm².
  • Manufactured according to DIN 223 (DIN EN 22568).
  • Made from HSS for long service life and accuracy.

Step-by-Step Guide (External Thread Cutting)
  1. Preparation: Choose the correct die (BSC). Deburr and clean the workpiece end.
  2. Clamping: Place the die into a die stock and secure it tightly.
  3. Starting: Position the die square to the workpiece and begin turning clockwise.
  4. Cutting: Turn continuously, apply cutting oil, and ensure smooth chip evacuation.
  5. Finishing: Cut until the desired thread length is achieved.
  6. Removing: Unscrew the die carefully counterclockwise.
  7. Checking: Test the finished thread with a gauge or bike component.

Technical Features (BSC)
  • Thread type: BSC bicycle thread according to BS 811
  • Standard: DIN 223 (DIN EN 22568)
  • Material: HSS
  • Application: General use; non-alloyed & low alloy steels up to 800 N/mm²
