1. Material The hexagonal die with NPT pipe thread is primarily crafted from carbon steel and undergoes heat treatment, achieving a hardness of approximately 5662 HRC. This hardness ensures toughness, tempering stability, and outstanding abrasion resistance. 2. Strong Practicality The carbon steel trimmer with NPT pipe thread features a hexagonal design that fits most wrenches and machine tools, making it versatile for various applications. Multiple chip removal slots facilitate smooth ejection of metal chips, preventing clogging and ensuring efficient task completion. 3. Scope of Application This tool is designed for machining, correcting, or cleaning external threads. It is suitable for general thread cutting in materials such as stainless steel, aluminum alloy, cast iron, copper, iron, aluminum, and plastic. It is ideal for maintenance and work on pipes, plates, and machinery. 4. Easy to Use The threaded hex die strictly adheres to the most common pipe thread standard—NPT taper tube with 60° teeth. Precision machining ensures clear, flat threads that are robust enough for most threadcutting tasks.
