Baer Round Cutting Die UN 1-5/16 x 12 - HSS is a general‑use tool crafted to cut external threads on cylindrical stock by hand with a die stock. Built for reliability in everyday machining, it’s a solid choice for both hobbyists and professionals who value precise, repeatable threads.

• Material: High-speed steel (HSS) construction for toughness and wear resistance.
• Thread standard: UN 12 TPI (12 threads per inch) with right‑hand direction; designed to DIN 223 (DIN EN 2256) standards for broad compatibility.
• Size: Nominal diameter UN 1-5/16" x 12; outer diameter approximately 1.3125" (about 33.34 mm); height around 18 mm.
• Chamfer: Chamfer of 1.75° to ease starting threads and improve cutting accuracy.
• Construction details: Four cutting edges inside the circular die with a groove for chip clearance; intended for use with standard die stocks and holders.
• Applications: General-purpose threading on common structural steels, copper, and compatible materials, suitable for typical engineering tasks up to about 750 N/mm².

With this Baer die, you can create robust, clean external threads on rods, bolts, or shafts without complex equipment. The durable HSS tooling maintains sharp cutting edges for consistent engagement with mating parts, reducing the risk of cross‑threading. Its compact form and standard die stock compatibility make it a dependable choice for repairs, prototyping, and light fabrication in both workshop and field settings.
