With a 3\/8 inch mill diameter, 7 flutes, and a 0.015 inch corner radius, this tool delivers a fine surface finish while maintaining edge integrity under heavy cutting loads. The close pitch and variable index geometry help reduce chatter and harmonic vibration. A TiN coating increases surface hardness and wear resistance. Licensed machinists, tool and die makers, and CNC operators use this end mill for finishing passes in steel, stainless steel, cast iron, superalloys, and titanium.\u003c\/p\u003e\n\u003cp\u003eThe SGS 77143 belongs to the Series 77C and is built for finishing applications where tight tolerances and surface quality are critical. It is suited for use in end mill holders on CNC machining centers handling steel, stainless steel, cast iron, superalloys, and titanium. The right-hand flute direction and right-hand cutting action are standard for conventional vertical and horizontal milling setups. With a 1.625 inch length of cut and 3 inch overall length, it accommodates moderate-depth finishing passes in both production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge sharpness in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e7-flute, close-pitch design maximizes chip contact for smooth finishing passes\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces chatter and vibration during the cut\u003c\/li\u003e\n  \u003cli\u003eTiN coating improves surface hardness and extends tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e0.015 inch corner radius protects the cutting edge and reduces stress concentrations at shoulder corners\u003c\/li\u003e\n  \u003cli\u003eChipbreaker geometry helps manage chip evacuation during finishing cuts\u003c\/li\u003e\n  \u003cli\u003eSingle-end, straight-cylindrical shank fits standard end mill holders without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with end mill holders on CNC machining centers. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium. Secondary application covers hard materials. Not centercutting; this tool is intended for peripheral and finishing passes, not plunge cutting.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified machinists or CNC operators with the machine fully powered down and the spindle locked before tooling changes. Seat the straight-cylindrical shank fully into the end mill holder and torque the retention mechanism to the holder manufacturer specification. Confirm runout with a dial indicator before engaging the workpiece. This tool is not centercutting and should not be used for plunge or drill-entry operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 15\/16 inch (1.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0020 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0016 to 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\u003eOverall Length Tolerance\u003c\/strong\u003e: +\/- 0.0620 inches\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: TiN\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\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Close\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 77C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: End Mill Holders\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.13 inches (L) x 0.55 inches (W) x 0.55 inches (H)\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: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 77143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51749518442802,"sku":"77143","price":142.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2ce39e0ca3a1483bc4b501a5b888ef7_4d5ba6ba-e9b4-40ab-af4a-d25ba1a1646e.jpg?v=1788907121","url":"https:\/\/voomisupply.com\/products\/sgs-77143-corner-radius-end-mill-3-8-in-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
