It features a 0.75 inch cutting diameter, a 1.875 inch length of cut, and a 4 inch overall length with a 0.75 inch straight-cylindrical shank. Seven flutes with a variable helix angle of 37 degrees improve chip evacuation and reduce harmonic vibration during interrupted or deep cuts. A titanium nitride (TiN) finish increases surface hardness and wear resistance. The micrograin carbide substrate supports higher feed rates and longer tool life compared to standard carbide grades. This tool is installed by machinists and CNC operators working in job shops, production environments, and tool rooms.\u003c\/p\u003e\n\u003cp\u003eThe SGS 77245 is suited for milling hardened steels, cast irons, stainless steels, aluminum and other non-ferrous metals, heat-resistant superalloys, and a broad range of engineered materials as indicated by workpiece material codes H, K, M, N, P, and S. It is a right-hand cut, right-hand flute, spiral flute design classified under SGS Series 77. The regular-length geometry fits standard tool holders and collet chucks without extended-reach adapters. Typical applications include slotting, peripheral milling, and contouring in both wet and minimum-quantity lubrication setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e7-flute variable helix at 37 degrees reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases hardness and lowers friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute for conventional CNC mill spindles\u003c\/li\u003e\n  \u003cli\u003eh6 tolerance on both mill diameter and shank diameter for precise tool holder fit\u003c\/li\u003e\n  \u003cli\u003eNon-center-cutting geometry — not intended for direct plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and production end mill for CNC machining centers and manual mills accepting a 0.75 inch straight-cylindrical shank via collet chuck, end mill holder, or shrink-fit tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes must be performed with the spindle fully stopped and the machine control in a safe state. Seat the shank fully into the tool holder and torque the retention mechanism per the tool holder manufacturer specification. Confirm runout with a dial indicator before cutting, as excessive runout accelerates edge wear on high-flute-count carbide tools. This tool is not center-cutting — use a pilot hole, ramp entry, or helical interpolation when entering a closed pocket.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\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 (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\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\u003eCentercutting\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\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\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.062 \/ -0.062 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 77\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: 77245\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51748609687858,"sku":"77245","price":516.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37c9d26a24b9df3c4974624afb507dc3_b00a3189-5ca5-4a6a-96ef-e217879d1e89.jpg?v=1788895689","url":"https:\/\/voomisupply.com\/products\/sgs-77245-square-end-mill-7-flute-solid-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
