Built from micrograin carbide and coated with Titanium Nitride (TiN), this tool delivers extended wear resistance and cutting life. It features a 0.75 inch mill diameter, a 3 inch length of cut, and a 5.25 inch overall length, placing it in the extra long category for deeper reach operations. The 7-flute configuration improves chip load distribution and surface finish quality. A variable helix geometry reduces chatter and vibration during aggressive cuts. A chipbreaker edge promotes efficient chip evacuation in tougher materials.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for machining a broad range of workpiece materials, including hardened steels, cast iron, stainless steel, non-ferrous metals, aluminum alloys, and high-temp alloys, corresponding to material codes H, K, M, N, P, and S. The extra long length of cut makes it a practical choice for deep pocket milling, slotting, and profiling where standard-length tooling cannot reach. It is used in CNC machining centers and manual mills across production shops, tool rooms, and precision job shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTitanium Nitride (TiN) coating extends tool life and reduces friction\u003c\/li\u003e\n\u003cli\u003e7-flute design improves feed rates and surface finish\u003c\/li\u003e\n\u003cli\u003eVariable helix reduces vibration and chatter during cutting\u003c\/li\u003e\n\u003cli\u003eChipbreaker geometry aids chip evacuation in deep cuts\u003c\/li\u003e\n\u003cli\u003eExtra long 3 inch length of cut for deep pocket and profiling operations\u003c\/li\u003e\n\u003cli\u003eh6 tolerance on both mill diameter and shank diameter for precise fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the SGS Series 77 end mill family.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Use a calibrated torque wrench and the correct collet or end mill holder to achieve proper clamping without distorting the shank. Verify runout with a dial indicator after seating to ensure concentricity within acceptable tolerance before beginning a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\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: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 77\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H, K, M, N, P, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.38 inches L x 1.2 inches W x 1.2 inches H\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 77278\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51727278866738,"sku":"77278","price":597.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6defa9232ac58b527f7e6baa71b2cef8.jpg?v=1788675817","url":"https:\/\/voomisupply.com\/products\/sgs-77278-square-end-mill-0-75in-7-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
