This single-end, center-cutting tool features a 3\/8-inch diameter with a 0.09-inch corner radius and six helical flutes arranged in a close-pitch, right-hand cutting configuration. The 45-degree high helix geometry promotes efficient chip evacuation and reduces cutting forces. An AlTiN (aluminum titanium nitride) PVD coating provides excellent heat and wear resistance, making this tool well-suited for dry or semi-dry machining. Machining professionals and toolroom operators rely on this geometry for precise finishing passes on tough workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThe XF-602-12-090 is intended for finishing operations on steel, stainless steel, cast iron, superalloys, and titanium. Its 7\/8-inch length of cut and 2-1\/2-inch overall length make it appropriate for shallow-to-moderate depth milling in production and toolroom environments. The Weldon flat shank is compatible with standard side-lock toolholders and collet chucks equipped for that shank profile. This end mill fits CNC machining centers and manual knee mills used by machinists, tool and die makers, and aerospace and precision manufacturing shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin substrate for high rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating rated for steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eSix-flute close-pitch design optimized for finishing-grade surface finishes\u003c\/li\u003e\n  \u003cli\u003e45-degree high helix angle promotes smooth chip flow and reduces tool deflection\u003c\/li\u003e\n  \u003cli\u003e0.09-inch corner radius reduces stress concentration and extends tool life at workpiece corners\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank for positive engagement in side-lock toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard side-lock toolholders and collet systems that accept a 3\/8-inch Weldon flat shank.

Verify toolholder runout with a dial indicator before committing to finish-depth passes, as excessive runout will accelerate wear on a six-flute finishing tool. Torque the Weldon flat setscrew per the toolholder manufacturer's specification. Confirm feeds, speeds, and depth of cut against the ROBBJACK XF series cutting data before first use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: XF-602\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0900 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.8750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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 Mill Material\u003c\/strong\u003e: Solid Carbide Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Close\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\u003eChipbreaker\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\u003eCoolant Through\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0010 to 0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: 0.0001 to 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0600 to 0.0600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: ROBBJACK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: XF-602-12-090\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":52110361035058,"sku":"XF-602-12-090","price":158.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74b5392f7428b1d1b12869615042e161_9b608b9f-847e-4929-a311-ff184ee4b9db.jpg?v=1790076187","url":"https:\/\/voomisupply.com\/products\/robbjack-xf-602-12-090-corner-radius-end-mill-3-8-in-6-fl","provider":"Voomi Supply","version":"1.0","type":"link"}
