Round Die: 5/16-18, 21 mm OD, High Speed Steel MPN:400237

Hardman 6744 round dies are manufactured from high speed steel materials to withstand the rigorous requirements of die sinking, chasing or thread rolling operations making them ideal tools for metalworking applications like jewelry, watches or automotive parts. They come fitted with a 5/16 -18 thread pitch design allowing adjustable fits when fitting into die holders thus making sure there's an accurate alignment between workpiece and die face ensuring quality finished product with precise details. The outside diameter measuring 21mm allows smooth passes while rolling threads hence ensuring uniformity across multiple pieces being produced avoiding human error during thread creation operations leading to cost savings due to less remakes thus meeting high volume production needs effectively. These dies offer excellent wear resistance properties due to the use of high speed steel construction providing consistent and accurate performance for long durability periods minimizing tool changeovers reducing downtime leading towards increased productivity uptime making it an essential tool in industries relying on fast yet precision thread creations such as automotive, military or machining sectors.
