It features a 1\/4 inch cutting diameter, a 0.045 inch corner radius, and four flutes with a right-hand spiral and medium helix geometry. The tool carries an AlTiN (aluminum titanium nitride) PVD coating, which supports cutting in heat-intensive applications involving superalloys, titanium, stainless steel, and ferrous metals. At 2.5 inches overall length with a 3\/4 inch length of cut, it is sized for standard toolholder setups in vertical and horizontal machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for both roughing and finishing operations on difficult workpiece materials including titanium alloy, Inconel, stainless steel, cast iron, and alloy steel. The 0.045 inch corner radius reduces stress concentration at the cutting edge, extending tool life in interrupted cuts and hard materials. The straight cylindrical shank at 1\/4 inch diameter fits standard precision toolholders. Single-end configuration makes it a direct consumable replacement in production and job-shop environments where consistent edge geometry is required across runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.045 inch corner radius reduces edge chipping in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating improves heat resistance and tool life in superalloys and stainless steel\u003c\/li\u003e\n  \u003cli\u003eFour-flute right-hand spiral geometry supports both roughing and finishing passes\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and dimensional stability at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eNormal pitch, medium helix, and straight cylindrical shank for compatibility with standard toolholders\u003c\/li\u003e\n  \u003cli\u003eCorner radius tolerance of -0.0010 to 0.0010 inches and mill diameter tolerance of -0.0020\/0.0000 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard precision toolholders.

Ensure the toolholder is clean and free of debris before seating the shank, and torque the retention screw or collet nut to the toolholder manufacturer specification. Verify runout with a dial indicator before production cutting. Do not exceed the recommended depth of cut or feed rate for the workpiece material, as solid carbide tools are brittle under excessive lateral load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.045 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0010 to 0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020\/0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloys and Titanium, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: TITAN USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TC74122\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51748450730290,"sku":"TC74122","price":48.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a85ba67f8ac7723278d272de46ce350b_08eb2885-d987-4e18-81ba-e1c7d3bb9fa7.jpg?v=1788893927","url":"https:\/\/voomisupply.com\/products\/titan-usa-tc74122-corner-radius-end-mill-1-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
