It features a 1\/2 inch diameter, a 1-1\/2 inch length of cut, and a 0.02 inch corner radius that reduces stress concentrations at the base of milled features. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. With four flutes and a bright\/uncoated finish, this tool is suited for high-precision work where dimensional accuracy is critical. Machinists and CNC operators working in job shops, tool rooms, and production environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is appropriate for use on CNC machining centers and manual mills handling ferrous and non-ferrous materials where a corner radius profile is required. The extra-long overall length of 6 inches extends reach for deep-pocket and long-reach milling scenarios. Its centercutting design allows direct plunge entry, adding versatility to slotting, profiling, and ramping operations. The right-hand flute direction and right-hand cutting direction are standard for conventional CNC setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.02 inch corner radius reduces tool stress and improves part surface finish at pocket corners\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral design supports efficient chip removal and stable cutting\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth cutting action and reduces chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge milling and ramping entry\u003c\/li\u003e\n\u003cli\u003eExtra-long 6 inch overall length provides extended reach for deep-pocket work\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction delivers hardness and wear resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill for use in standard 1\/2 inch collet or end mill holders on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Secure the shank fully in a clean, properly sized collet or end mill holder to the recommended engagement depth before tightening. Inspect the tool and holder for runout before beginning a cut.
