Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, this tap produces clean 3\/8-16 UNC threads in a range of materials including mild steel, aluminum, and plastics. The spiral point geometry pushes chips ahead of the cut rather than packing them into the flutes, making it well-suited for through-hole tapping at production feed rates. The 3-flute plug chamfer configuration provides a gradual lead-in and reduces the torque required to start the thread. Class 3B fit tolerance and H3 thread limit ensure threads meet standard fastener mating requirements.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shops, manufacturing facilities, and maintenance environments where 3\/8-16 UNC through-hole threads are required. Typical applications include tapping steel plate, aluminum extrusions, cast iron housings, and structural components. The plug chamfer makes it appropriate for production tapping operations on drill presses, CNC machining centers, and manual tapping machines. Right-hand thread direction aligns with standard toolholder and drive configurations. The TiN coating extends tool life in abrasive materials and reduces built-up edge during cutting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread form for standard inch-series fastener compatibility\u003c\/li\u003e\n  \u003cli\u003eSpiral point design pushes chips forward, ideal for through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eTiN coating improves wear resistance and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit holds Class 3B fit for precise thread tolerance control\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides controlled lead-in and reduced starting torque\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, compatible with standard drive setups and tapping heads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard spiral point plug tap for use in through-hole tapping of 3\/8-16 UNC threads; compatible with standard tap holders, tapping heads, and collet chucks sized for 3\/8-inch shank taps.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Always secure the workpiece and ensure the tap is properly aligned with the drilled hole before engagement to prevent tap breakage. Use an appropriate cutting fluid for the material being tapped.
