Built from micrograin solid carbide, it offers high rigidity and edge retention compared to HSS tooling. The 0.125 inch corner radius reduces stress concentrations at pocket floors and shoulders, extending part and tool life. A TiCN (titanium carbonitride) coating lowers friction and improves wear resistance in ferrous and non-ferrous cutting applications. With a 0.750 inch mill diameter, a 2.25 inch length of cut, and a 5 inch overall length, this is a long-series end mill suited to deeper cavity work that standard-length tools cannot reach.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard CNC machining centers, vertical mills, and manual mills equipped with a 0.750 inch collet or end mill holder. The long LOC and single-end, centercutting geometry make it appropriate for plunge entry, side milling, and full-slot operations in steel, stainless, cast iron, and harder non-ferrous materials. Right-hand cutting direction and right-hand spiral fluting are standard for conventional and climb milling on most CNC and manual setups. It is sold as a single unit and is typically purchased by machinists, tool-and-die makers, and CNC programmers working in job shops or production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for high rigidity and extended edge life\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and improves wear resistance in ferrous and non-ferrous cutting\u003c\/li\u003e\n  \u003cli\u003e0.125 inch corner radius reduces stress at pocket floors and improves surface finish at part corners\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eLong-series length of cut (2.25 inches) for deep cavity and deep shoulder milling\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral geometry with right-hand cut and right-hand flute direction for standard CNC and manual mill setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 0.750 inch collet chucks or end mill holders on CNC machining centers and manual vertical mills.

Secure the shank fully within the holder to the recommended minimum engagement depth per the holder manufacturer before tightening. Verify runout with a dial indicator after mounting, as excessive runout accelerates corner radius wear and degrades corner geometry. Feed, speed, and depth-of-cut parameters should be set per the material being cut and should not exceed the tool manufacturer recommendations for this diameter and coating combination.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.04 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12183143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732637942066,"sku":"12183143","price":277.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/52505c9a0f2a92263f53a613a7899784.jpg?v=1788745300","url":"https:\/\/voomisupply.com\/products\/accupro-12183143-corner-radius-end-mill-3-4-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
