HORNIT NPT závitník 3/4-14 DIN-374C HSSE 800

The HORNIT NPT Tap 3/4-14 DIN-374C HSSE 800 is a high-performance threading tool designed for cutting internal NPT (National Pipe Taper) threads in a variety of materials. Manufactured from premium HSSE (High-Speed Steel with Cobalt), this tap offers exceptional durability and heat resistance, ensuring long tool life even in demanding applications. With a nominal pipe size of 3/4 inch and 14 threads per inch, it delivers precise and consistent threads for pipe fittings and connections.

Advantages

Made from HSSE 800 material, this tap provides superior wear resistance and toughness compared to standard HSS taps. The cobalt content enhances red hardness, allowing for higher cutting speeds and improved performance on harder materials. The straight flute design ensures efficient chip evacuation and reduces the risk of clogging, resulting in cleaner threads and reduced torque during operation. Compliant with DIN 374 standard and tolerance class C, it guarantees reliable and accurate threading every time.
