- Thread specification: 1/4"-28 UNF left-hand thread, suitable for applications requiring reverse-threaded fasteners.
- Cutting edges: Precisely ground edges deliver clean, accurate thread formation and smooth engagement with mating parts.
- Diameter: 1/4 inch nominal diameter aligns with standard threading stock and tooling setups.

This Baer circular die helps you produce dependable left-handed threads on shafts and rods, reducing rework and ensuring a solid fit with corresponding components. The combination of HSS construction and precision-ground cutting edges provides long tool life and repeatable results across multiple projects, whether you’re rebuilding machinery, fabricating fixtures, or fabricating custom fasteners. For best results, pair with a compatible die stock and light cutting fluid to maintain smooth operation and accurate thread form.
