Built from micrograin solid carbide with a bright\/uncoated finish, it delivers consistent cutting performance in demanding machining environments. The 3\/4-inch diameter tool carries a 0.03-inch corner radius across 3 right-hand spiral flutes, producing smooth edge transitions and reducing stress concentrations in finished workpiece profiles. With a 1-5\/8-inch length of cut and 4-inch overall length, it suits a wide range of peripheral and slot milling applications on CNC machining centers and manual mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for job shops, tool rooms, and production machining environments where accurate corner radii and tight diameter tolerances are required. The centercutting geometry allows direct plunge entry, adding flexibility for ramping and pocket milling operations. The single-end configuration and 3\/4-inch shank diameter make it compatible with standard ER and side-lock toolholders commonly found on vertical and horizontal machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e0.03-inch corner radius reduces corner chipping on finished profiles\u003c\/li\u003e\n  \u003cli\u003e3 right-hand spiral flutes with right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge, ramp, and helical interpolation entry\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for non-ferrous and general-purpose milling\u003c\/li\u003e\n  \u003cli\u003eTight mill diameter tolerance of +0.0002\/-0.0008 inches for consistent fitment and runout control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills using 3\/4-inch straight-shank toolholders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes must be performed by a qualified machinist with the spindle fully stopped and machine power isolated.
