It carries an AlTiN (aluminum titanium nitride) PVD coating, which extends tool life when cutting superalloys, titanium alloys, stainless steel, and hardened cast iron. The 0.0600-inch corner radius reduces stress concentration at the cutting edge and improves surface finish on profiled features. At 6 inches overall length with a 3-inch length of cut, this is an extra-long geometry suited for deep-pocket milling, cavity work, and extended-reach applications where a standard-length tool cannot reach the workpiece.\u003c\/p\u003e\u003cp\u003eThis end mill is built for CNC machining centers handling roughing and finishing passes in ferrous metals, high-temperature alloys, Inconel, stainless steel, and titanium alloy workpieces. The straight cylindrical shank accepts standard toolholders and collet chucks. The right-hand flute direction and right-hand cutting geometry follow conventional milling setup. The 30-degree helix angle and normal pitch promote chip evacuation and stable cutting forces. Machinists running aerospace, medical, and heavy industrial parts will find this tool particularly suited for materials that rapidly wear uncoated carbide.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN PVD coating for extended life in superalloys, stainless steel, titanium, and cast iron\u003c\/li\u003e\n\u003cli\u003e0.0600-inch corner radius with tolerance of -0.0010 to +0.0010 inches for consistent edge geometry\u003c\/li\u003e\n\u003cli\u003eExtra-long 6-inch OAL with 3-inch length of cut enables deep-reach pocket milling\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and heat resistance at high cutting speeds\u003c\/li\u003e\n\u003cli\u003eRight-hand, spiral flute geometry supports conventional and climb milling in CNC setups\u003c\/li\u003e\n\u003cli\u003eSingle-end, centercutting-style corner radius end geometry suitable for both roughing and finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-shank toolholders and collet chucks accepting a 3\/4-inch shank diameter.

Confirm toolholder runout is within acceptable limits before engaging the cut, as elevated runout accelerates edge wear on carbide tools. Power down the spindle and follow lockout\/tagout procedures before loading or changing the tool. Avoid side-loading the tool beyond the recommended depth of cut for the workpiece material to prevent chipping the carbide substrate.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 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: 3.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 inches\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: -0.0030 \/ 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Superalloys and Titanium, Stainless Steel, Cast Iron, High-Temperature Alloy, Alloy Steel, Inconel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\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 Index\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.16 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: TC74656\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51736858263858,"sku":"TC74656","price":358.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd47e8aa7038d40d36ccb972eb4125a1_d1bcd9c1-1e3c-4994-b4cf-08f7774d1118.jpg?v=1788781158","url":"https:\/\/voomisupply.com\/products\/titan-usa-tc74656-corner-radius-end-mill-3-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
