• High Carbon Steel Construction: Made from high carbon steel, this die offers exceptional strength and durability, providing a long service life and reliable performance.
• Clear Identification: The thread size is clearly etched on the die, allowing for quick and easy identification, reducing the chance of using the wrong tool for the job.

SPECIFICATIONS:

• Model: Irwin / Hanson 7404
• Thread Size: 3/8"-18 NPT
• Hexagon Width: 1-7/16 inches
• Threads per Inch: 18
• Die Material: High Carbon Steel
• Cutting Direction: Right-hand

HOW TO USE:

1. Preparation: Ensure the damaged pipe is clean and free of debris. If necessary, use a wire brush to remove any rust or dirt from the existing threads.
2. Lubrication: Apply a suitable cutting oil to both the pipe threads and the die. This reduces friction and heat, resulting in a cleaner cut and extending the life of the tool.
3. Positioning: Place the die squarely over the damaged threads of the pipe. Ensure the die is aligned properly to follow the existing thread pattern.
4. Cutting: Using a wrench or socket on the hexagon head, turn the die clockwise. Apply steady, firm pressure while rotating. After each full turn, reverse the rotation slightly to break off chips and clear the flutes.
5. Completion: Continue turning the die until the re-threaded section is complete. Remove the die and clean the pipe to remove any metal shavings and excess oil.
