Irwin 1/4"-20 NC HCS 1" Across Hexagon Fractional Die (6520ZR)

The Irwin 1/4"-20 NC Hexagon Fractional Die (6520ZR) is a high-performance threading tool engineered for both professionals and DIY enthusiasts. This precision-made die is crafted from high-carbon steel, a material known for its strength and ability to maintain a sharp cutting edge. It is specifically designed to create new 1/4"-20 NC threads or repair existing ones that have been stripped, rusted, or otherwise damaged. Its unique hexagon shape gives it a distinct advantage over traditional round dies, allowing it to be used with a die stock for standard operation or, in situations where space is restricted, with a common wrench or socket. This versatility makes it an indispensable tool for a wide range of applications, including automotive repair, plumbing, and general maintenance. The Irwin 6520ZR ensures consistent, clean, and accurate threads, helping you complete projects with a professional finish.

HOW TO USE:

1. Preparation: Secure the bolt or rod in a vise, ensuring it is held firmly. Select the correct die stock or wrench for the 1" hexagon size. If the bolt is damaged, use a file to clean the end and create a smooth, chamfered start.
2. Lubrication: Apply a generous amount of cutting oil to the area where the threads will be cut or repaired. This helps reduce friction, prolongs the life of the die, and results in a smoother finish.
3. Threading: Place the die squarely on the end of the bolt or rod. Apply firm, even pressure and turn the die clockwise. Turn the die a quarter turn forward, then a half turn backward to break the chips.
4. Completion: Continue this back-and-forth motion until the desired length of thread has been created. Remove the die and clean the newly cut threads with a wire brush to remove any metal shavings.
