THR NPT 1/4×18 7.1xD8x60

Description

THR NPT 1/4×18 7.1xD8x60 is a high-precision solid carbide thread mill engineered for CNC machining of 1/4-18 NPT (National Pipe Taper) internal threads used in hydraulic fittings, pneumatic components, mould tooling, and industrial fluid systems. This CNC threading cutter is designed to produce accurate taper, clean thread profile, and smooth sealing surfaces in materials such as stainless steel, P20 steel, D2 tool steel, alloy steel, and hardened engineering metals.

Manufactured from premium micro-grain carbide rod, this thread mill provides excellent wear resistance, cutting edge strength, and thermal stability, allowing reliable performance in high-speed CNC machining centers. Compared to conventional tapping, thread milling offers better chip control, improved dimensional accuracy, and lower risk of tool breakage, especially when machining tough or hardened materials. This makes it the preferred choice for die & mould machining, aerospace fittings, automotive components, and precision mechanical parts.

With a 7.1 mm cutting diameter, D8 shank, and 60 mm overall length, this tool offers strong rigidity and precise control for accurate NPT internal threading. The rigid shank ensures low run-out, excellent concentricity, and smooth thread finish, resulting in leak-proof and perfectly formed pipe threads that meet industrial sealing requirements.

This tool is commonly searched as NPT thread mill, carbide thread milling cutter, CNC pipe thread tool, solid carbide threading tool, precision carbide tools India, and CNC cutting tools manufacturers, making it highly visible to buyers searching for industrial cutting tools suppliers and CNC tools supplier in India.

The THR NPT 1/4×18 7.1xD8x60 is widely used in hydraulic manifolds, pneumatic blocks, mould inserts, valve bodies, and fluid connectors, where precise thread geometry and reliable sealing are critical. Its ability to maintain consistent pitch and accurate taper makes it an essential tool for high-precision CNC machining environments.
