With a 1\/4 inch cutting diameter, 7 flutes, and a variable helix geometry, it delivers reduced chatter and improved chip evacuation compared to standard fixed-helix designs. The TiN coating adds surface hardness and wear resistance for extended tool life. At 3\/4 inch length of cut and 2-1\/2 inch overall length, this is a long-series tool suited for applications requiring additional reach. The micrograin carbide substrate supports tight tolerances with an h6 shank and mill diameter tolerance. A chipbreaker is integrated into the flute geometry. Installed by machinists, toolroom technicians, and CNC operators.\u003c\/p\u003e\u003cp\u003eThe SGS 77115 is built for milling hard and difficult-to-cut materials. Compatible material codes include H, K, M, N, P, and S, which correspond to hardened steels, cast irons, stainless steels, non-ferrous metals, carbon and alloy steels, and heat-resistant superalloys. This tool is used in CNC machining centers and manual mills for slotting, profiling, and peripheral milling in production and toolroom environments. The long-series length makes it suitable for deep-feature milling where standard-length tools cannot reach.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-flute variable helix design reduces harmonics and chatter during aggressive cuts\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction provides rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiN finish increases surface hardness and extends tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003eChipbreaker geometry assists with chip management in long-reach and deep-slot applications\u003c\/li\u003e\n\u003cli\u003eh6 tolerance on both shank and mill diameter ensures precise fitment in standard collets and toolholders\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute spiral geometry compatible with standard CNC and manual spindle configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with workpiece material codes H, K, M, N, P, and S as specified by the manufacturer.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank to the full recommended grip depth in the collet or toolholder before torquing. This tool is not center-cutting and should not be used for direct plunge operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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\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\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\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\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: 77115\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51731578782002,"sku":"77115","price":90.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2ce39e0ca3a1483bc4b501a5b888ef7_8d42f56e-54bf-44fc-b9ab-f72c2ce8a186.jpg?v=1788732747","url":"https:\/\/voomisupply.com\/products\/sgs-77115-square-end-mill-1-4-in-7-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
