With 3 flutes and an AlTiN coating, this tool delivers clean thread profiles and extended tool life in a wide range of workpiece materials. The cutting diameter is 0.1240 inches, the length of cut is 0.4410 inches, and the overall length is 2.5 inches. The 3\/16-inch (0.1875 inch) shank fits standard collet chucks and toolholders used in CNC machining centers. This is a precision ground carbide tool intended for use by skilled machinists and toolroom professionals.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for CNC machining of M4x0.7 threads in both through-hole and blind-hole configurations. The helical flute geometry allows a single-pass thread interpolation strategy, reducing cycle time compared to tapping operations. It is appropriate for use in steel, stainless steel, aluminum, and other machinable metals. Internal thread milling requires a machine capable of helical interpolation. External thread milling is also supported with this tool, making it a versatile option for shops producing small-diameter threaded features on precision components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts M4x0.7 threads in both internal and external configurations\u003c\/li\u003e\n  \u003cli\u003e3-flute helical geometry supports smooth chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating improves heat resistance and extends tool life in ferrous and hardened materials\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and dimensional stability at high spindle speeds\u003c\/li\u003e\n  \u003cli\u003e0.4410-inch length of cut accommodates typical thread depth requirements for M4 fastener applications\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design  -  suitable for use with external coolant or mist lubrication\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification helical flute thread mill for M4x0.7 thread profiles in CNC machining applications requiring helical interpolation capability.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists on CNC machining centers capable of helical interpolation. Secure the 3\/16-inch shank in a precision collet or shrink-fit toolholder and verify runout before cutting. Confirm correct thread interpolation programming before engaging the workpiece.
