Built from high speed steel with a bright uncoated finish, this bottoming tap features a 3-flute geometry that clears chips efficiently in short-thread-depth situations. With an overall length of 1.938 inches and a thread length of 0.31 inches, it is sized for compact M3 work where full thread depth close to the bottom of a blind hole is required. The 6H class of fit and D3 thread limit deliver consistent tolerance control for general-purpose metric threading. Machinists and tool-and-die technicians reach for this tap when standard plug or taper taps cannot reach full depth.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for manual tapping operations in job shop, maintenance, and production environments. It handles blind-hole and through-hole threading in a range of workpiece materials. Its bottoming chamfer — typically 1 to 2 thread leads — allows threading to the bottom of a blind hole after a plug tap has started the thread. Series 1003 identifies this as a standard Cleveland metric hand tap line intended for light-duty hand and machine-assisted tapping setups.\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\u003e3-flute straight-flute geometry for efficient chip evacuation in short-thread applications\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup to affect thread tolerance\u003c\/li\u003e\n  \u003cli\u003e6H class of fit with D3 thread limit for consistent metric tolerance control\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, M3x0.50 metric coarse pitch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading M3x0.50 metric coarse threads in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces in both blind-hole and through-hole applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by machinists or maintenance technicians using a standard tap wrench or T-handle; ensure the workpiece is securely fixtured before tapping. Use a plug or taper tap to start the thread before using this bottoming tap in a blind hole. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish.
