It features a 1 inch cutting diameter, a 1.5 inch length of cut, and a 3.04 mm (0.1200 inch) corner radius that reduces stress concentrations at the cutting edge and extends tool life. With 5 flutes, a variable helix, and variable index geometry, the 121340 delivers improved surface finish and reduced chatter compared to standard fixed-helix tools. The nACo-style FX1 coating adds heat and wear resistance. Machining professionals and toolroom technicians use this end mill in CNC machining centers and manual mills for precision contouring, slotting, and profiling.\u003c\/p\u003e\n\u003cp\u003eThe 121340 is suited for roughing and finishing operations on steel, cast iron, superalloys, titanium, hard materials, and stainless steel. Its short-length geometry and 1 inch straight-cylindrical shank (h6 tolerance) make it a stable choice for high-feed applications where rigidity matters. The centercutting design allows plunge entry, adding versatility in 3-axis and multi-axis machining environments. This tool fits standard end mill holders and is appropriate for production shops and toolrooms working across a range of ferrous and difficult-to-machine alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 inch cutting diameter with 1.5 inch length of cut for short, rigid stick-out\u003c\/li\u003e\n  \u003cli\u003e3.04 mm corner radius reduces edge chipping and improves corner durability\u003c\/li\u003e\n  \u003cli\u003e5-flute variable helix and variable index design minimizes chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eFX1 coating provides wear and thermal resistance for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand helical flutes with submicron carbide grade for edge toughness in superalloys and hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill holders.
