With a 1 inch cutting diameter, a 1.75 inch length of cut, and a 0.01 inch corner radius, this tool delivers controlled edge geometry that reduces stress concentration at part corners and extends tool life in demanding cuts. The 4-flute, right-hand spiral configuration provides efficient chip evacuation and a stable cutting action suited to ferrous and non-ferrous materials. Machined from micrograin carbide stock and left in a bright uncoated finish, this end mill is installed by CNC machinists and manual mill operators working in job shops, tool rooms, and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is built for profiling, slotting, and contouring operations where a small corner radius is required to meet part print tolerances. The centercutting design allows plunge entry, giving operators flexibility in tool paths without requiring a pre-drilled start hole. With a 1 inch shank diameter and 4 inch overall length, it seats directly in standard ER or end mill holders sized for 1 inch straight shanks. The single-end configuration and right-hand cutting direction are consistent with conventional CNC vertical and horizontal milling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.01 inch corner radius reduces stress risers and meets tight fillet requirements on finished parts\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction provides rigidity and wear resistance in hard or abrasive materials\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand spiral design balances chip load and surface finish in profiling cuts\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with or without cutting fluid across a range of materials\u003c\/li\u003e\n\u003cli\u003e1 inch shank diameter matches standard collet and end mill holder tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual milling machines equipped with tool holders accepting a 1 inch straight shank end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or CNC setup technician. Secure the shank fully into a clean, properly sized end mill holder or collet chuck and torque the retention hardware to the holder manufacturer specification. Inspect the shank and holder bore for chips or contamination before seating.
