Built on the Series 77 platform, this tool features a 5\/8 inch cutting diameter, 7-flute geometry, and a variable helix design that helps reduce chatter and harmonics during high-speed milling. The TiN (titanium nitride) finish increases surface hardness and extends tool life in abrasive cutting conditions. The micrograin carbide substrate provides a balance of edge sharpness and wear resistance. This end mill is installed and operated by machinists and CNC programmers working in job shop, production, and tool and die environments.\u003c\/p\u003e\u003cp\u003eThe SGS 77209 is suited for milling a wide range of workpiece materials. The manufacturer material codes indicate compatibility with hardened steels (H), cast irons (K), stainless steels (M), non-ferrous metals (N), steel alloys (P), and superalloys (S). The 1-5\/8 inch length of cut and 3-3\/4 inch overall length make it well matched to medium-depth slotting, profiling, and peripheral milling operations in both vertical and horizontal CNC machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-flute spiral geometry increases feed rate potential compared to standard 4-flute end mills\u003c\/li\u003e\n\u003cli\u003eVariable helix angle reduces resonance and chatter at high spindle speeds\u003c\/li\u003e\n\u003cli\u003eTiN finish improves surface hardness and reduces built-up edge on ferrous materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers consistent edge integrity\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration for standard CNC spindle use\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank with h6 tolerance for accurate tool holder fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe SGS 77209 is compatible with workpiece materials designated under material codes H, K, M, N, P, and S, covering hardened steels, cast irons, stainless steels, non-ferrous metals, steel alloys, and superalloys.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Use a calibrated tool holder with appropriate h6 bore tolerance to maintain runout specifications. Confirm correct tool stick-out length and validate feeds and speeds against the workpiece material before running the first pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 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\u003eFinish\u003c\/strong\u003e: TiN\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\u003ePackage Weight\u003c\/strong\u003e: 0.05 pounds\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: 77209\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51731534872882,"sku":"77209","price":333.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37c9d26a24b9df3c4974624afb507dc3_43a8b1ea-28b5-499f-8e27-c9331973d7dd.jpg?v=1788732257","url":"https:\/\/voomisupply.com\/products\/sgs-77209-square-end-mill-5-8-inch-7-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
