Built from high-speed steel (HSS) with a bright uncoated finish, this plug-chamfer tap is suited for threading operations that require a reliable STI thread form in steel, aluminum, and similar materials. At 2 inches overall length with a 2-flute design and D1 thread limit, it delivers controlled cutting action in through-hole applications. Machinists and maintenance technicians use it when installing helical thread inserts to restore or create durable internal threads.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shops, production environments, and maintenance repair operations where M3 x 0.5 STI threads are required. The plug chamfer style makes it suitable for through-holes, providing the progressive cutting entry needed for consistent thread form across a range of workpiece materials. It is a single-piece item packaged individually, appropriate for both bench work and light production use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSTI metric coarse thread form for use with helical thread inserts\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides progressive cutting entry in through-holes\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for general-purpose threading performance\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n  \u003cli\u003eD1 thread limit for controlled thread fit\u003c\/li\u003e\n  \u003cli\u003e2-flute design assists chip evacuation in short-chipping materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for operations requiring M3 x 0.5 metric coarse STI taps in through-hole threading applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap should be installed in a compatible tap holder or tapping chuck set to the correct speed for the workpiece material.
