Baer Circular Die in high-speed steel (HSS) is built for precise external threading on cylindrical workpieces. This UNEF, right-hand die is designed for general-use threading tasks, offering reliable performance for both professional shops and DIY projects.

• Material: High-speed steel (HSS) construction for wear resistance and longer tool life.
• Thread form and size: UNEF (Unified National Extra Fine) right-hand threads, 1-3/16" diameter with 18 TPI.
• Cutting geometry: Precisely ground cutting edges to produce clean, accurate threads and smooth engagement with mating parts.
• Usage: Circular die designed for external threading on cylindrical workpieces and used with a die holder or die stock for controlled rotation.
• General-purpose reliability: Engineered for longevity in a wide range of threading tasks, reducing tool changes and downtime.

The Baer circular die is ideal for repairing or creating UNEF-threads on shafts, studs, spacers, and other cylindrical components. When paired with a compatible die stock and proper lubrication, it delivers consistent thread quality, minimizes chatter, and helps you achieve a reliable fit with nuts and other fasteners. Regular cleaning and a light coat of oil after use will preserve the cutting edges for future jobs.
