It features a 5\/8-inch mill diameter, a 0.06-inch corner radius, and 7 helical flutes ground from micrograin carbide. The AlTiN coating — marketed under SGS proprietary designation Ti-NAMITE-A — delivers thermal resistance and extended tool life in high-heat cutting environments. A close pitch configuration and variable index flute spacing reduce chatter and harmonics during aggressive passes. With a 2.5-inch length of cut and 4.5-inch overall length, this is a long-reach tool suited to deep-wall profiling and finishing passes where a standard-length end mill cannot reach.\u003c\/p\u003e\n\u003cp\u003eThe SGS 77242 is designed for finishing cuts in steel, stainless steel, cast iron, superalloys, and titanium, as well as hard materials. It is a single-end, right-hand cut, right-hand flute tool with a straight cylindrical shank compatible with standard end mill holders. The Series 77C geometry and close pitch make it particularly well suited to high-material-removal finishing passes on hardened workpieces. This tool is used primarily in CNC machining centers by machinists and toolroom professionals in job shop, aerospace, and precision manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate provides rigidity and edge retention in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN (Ti-NAMITE-A) coating resists heat buildup during dry and high-speed cutting\u003c\/li\u003e\n  \u003cli\u003e7-flute, close-pitch configuration maximizes surface finish quality and feed rate capability\u003c\/li\u003e\n  \u003cli\u003eVariable index fluting reduces resonance and chatter on deep-wall finishing passes\u003c\/li\u003e\n  \u003cli\u003e0.06-inch corner radius extends tool life and reduces edge chipping at the cutter tip\u003c\/li\u003e\n  \u003cli\u003eLong-reach geometry: 2.5-inch length of cut on a 4.5-inch overall length tool\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand helix, single-end design for use in standard end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill holders accepting a 5\/8-inch straight cylindrical shank.

Secure the straight cylindrical shank in a compatible end mill holder to the torque specifications required by the holder manufacturer. This tool is not centercutting and should not be used for direct plunge cuts; ramp or helical entry paths are required. Verify runout after clamping and before commencing a cut to protect both the tool and the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.06 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: -0.0020 to 0.0000 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: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (Ti-NAMITE-A)\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\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Close\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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\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\u003eLength Type\u003c\/strong\u003e: Long\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\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 77C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 77242\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51744672547122,"sku":"77242","price":393.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6defa9232ac58b527f7e6baa71b2cef8_ae43497f-9f86-4438-bd86-b2f63b04f7ed.jpg?v=1788859833","url":"https:\/\/voomisupply.com\/products\/sgs-77242-corner-radius-end-mill-5-8-inch-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
