Built from micrograin carbide, it delivers consistent cutting performance and edge retention in demanding machining environments. The 3-flute, spiral design with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 9\/64 inch (0.1406 inches) in diameter with a 1\/2 inch length of cut and 3\/16 inch shank, this is a small-diameter tool suited for fine-detail work, slots, and pocketing operations. It is centercutting, allowing direct plunge entry into the workpiece. Installed by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual milling machines where tight-tolerance small-diameter cuts are required. The right-hand cut and right-hand flute configuration are standard for conventional and climb milling setups. The uncoated micrograin carbide construction is appropriate for dry or wet cutting applications depending on material and shop practice. Its regular length profile fits standard toolholders accepting a 3\/16 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for superior edge retention and wear resistance\u003c\/li\u003e\n\u003cli\u003e3-flute spiral design with 40-degree helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge cuts without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute — standard for most milling setups\u003c\/li\u003e\n\u003cli\u003eTight mill diameter tolerance of +0.000 \/ -0.002 inches for precision fitment\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for a range of materials and cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or production end mill for CNC machining centers and manual mills accepting a 3\/16 inch shank diameter with right-hand rotation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and the tool is secured with the correct collet or toolholder sized for a 3\/16 inch shank before operation. Verify runout and tool projection before cutting.
