Part of the SS-2 series, this stub-length tool features a 1\/64 inch (0.0200 inch) cutting diameter and a 1\/32 inch length of cut, making it well-suited for fine detail work in tight geometries. The 30-degree helix spiral flute design promotes efficient chip evacuation, while the uncoated Tuffy-grade carbide substrate delivers hardness and wear resistance. Licensed machinists and CNC programmers working with miniature features will find this end mill fits standard 1\/8 inch straight-cylindrical shank toolholders at 1-1\/2 inches overall length.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for slot milling, profiling, and pocket milling in small-scale or micro-machining operations. Its centercutting capability allows direct plunge entry into workpiece material. The right-hand cut and right-hand flute configuration is standard for conventional CNC machining centers and manual mills. It is particularly applicable in industries where fine-feature milling of metals, plastics, or composites is required at the micro scale.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide Tuffy-grade construction for hardness and wear resistance in micro-milling applications\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without pilot drilling\u003c\/li\u003e\n\u003cli\u003e30-degree helix spiral flute promotes efficient chip evacuation at small cutting diameters\u003c\/li\u003e\n\u003cli\u003eStub length configuration (1\/32 inch LOC) provides rigidity to minimize deflection at micro scale\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for compatibility with standard CNC and manual mill setups\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for applications where coating buildup at micro diameters is a concern\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tool for CNC machining centers and manual mills accepting a 1\/8 inch straight-cylindrical shank end mill in the SS-2 series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholder torque and runout procedures for the specific collet or chuck in use. Confirm shank seating depth and minimize tool overhang to reduce deflection at this cutting diameter. Power down and lock out the spindle before changing tooling.
