The Baer Circular Die HSS - UNC - Right Hand - For Stainless Steels - No 4 x 40 is a precision external-threading tool designed for stainless steel applications. It’s built for machinists and fabricators who demand clean, accurate threads on cylindrical workpieces.

• Thread size: No. 4-40 UNC external thread for stainless steel shafts and rods
• Material: High-Speed Steel (HSS) for durable cutting edges and long tool life
• Thread direction: Right-hand threading standard
• Cutting geometry: Precisely ground edges for smooth engagement and consistent thread form
• Compatibility: Designed for use with a standard die stock or die holder for easy rotation and controlled cutting
• Application: Ideal for repairing or provisioning fine external threads on stainless components

Using this circular die in a die stock provides steady, controlled rotation, reducing tool chatter and producing uniform threads with minimal burrs. Its robust HSS construction is well-suited for repeated use in stainless environments, delivering reliable performance across repair, fabrication, and precision-threading tasks.
