Manufactured from high speed steel with a titanium nitride (TiN) coating, it offers improved wear resistance and longer tool life compared to uncoated taps. The straight 3-flute design suits hand tapping operations in a range of ferrous and non-ferrous materials. With an overall length of 1.9375 inches and a 0.625-inch thread length, this tap is sized for compact M3 x 0.50 metric coarse threading applications. It is right-hand thread direction and carries a D1 thread limit for close-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in maintenance, repair, and production environments where M3 x 0.50 metric coarse blind-hole threads are required. It is well suited for machine shops, toolrooms, and field service applications involving small fastener threads in metal components. The bottoming chamfer allows threading to within a few pitches of the bottom of a blind hole, making it appropriate as a finishing tap following a taper or plug tap. Machinists, maintenance technicians, and tool and die professionals routinely use this style of tap for precise, hand-driven threading work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eTiN coating improves wear resistance and reduces friction during cutting\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e3-flute straight flute design provides chip clearance in hand tapping operations\u003c\/li\u003e\n  \u003cli\u003eD1 thread limit for close-tolerance metric coarse thread production\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, M3 x 0.50 metric coarse standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for hand tapping M3 x 0.50 metric coarse blind holes in metalworking applications where a bottoming tap is required to complete thread depth.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is intended for use by machinists or trained technicians using a standard tap wrench. Always ensure the workpiece is securely clamped before tapping. Use an appropriate cutting fluid for the material being tapped to reduce tool wear and improve thread finish.
