It features a 0.125-inch (1\/8-inch) cutting diameter with a 0.375-inch length of cut and a 1.5-inch overall length. The four-flute, right-hand spiral design runs at a 30-degree helix angle, promoting efficient chip evacuation and smooth cutting action. A titanium nitride (TiN) coating improves surface hardness and extends tool life across a wide range of workpiece materials. Micrograin carbide construction delivers consistent edge integrity under demanding cutting conditions. This tool is suitable for machinists and toolroom professionals working with close-tolerance slots, pockets, and profiles.\u003c\/p\u003e\u003cp\u003eThe SGS 39177 is applicable across a broad range of material groups including hardened steels, cast irons, stainless steels, non-ferrous metals, structural steels, and high-temperature alloys, corresponding to material codes H, K, M, N, P, and S. Its variable index design reduces chatter and harmonic vibration during cut, making it well suited for finish milling passes in tight-tolerance work. The straight-cylindrical shank seats directly into standard collet chucks and milling tool holders with a 0.125-inch (1\/8-inch) bore. Regular-length geometry makes it a practical choice for benchtop CNC mills, vertical machining centers, and manual knee mills where clearance is not a limiting factor.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.125-inch cutting diameter with mill diameter tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003eFour-flute spiral configuration with 30-degree right-hand helix for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eTitanium nitride (TiN) coating for improved wear resistance and tool longevity\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for sharp, stable cutting edges\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces vibration and chatter during milling\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable, allowing direct plunge entry into workpiece material\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/8-inch bore collet chucks and milling tool holders.

Ensure the spindle is fully powered down and locked out before mounting or removing the end mill from the tool holder. Verify collet bore size matches the 0.125-inch shank diameter and that the tool is seated to the full recommended grip length before tightening. Inspect the cutting edges for chips or damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (1-1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 \/ -0.00032 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: 39177\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51751033798962,"sku":"39177","price":33.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d1fadfafaa1b1399170d1f68a383c816_2cb46c78-c084-4f5b-8983-8162005fa5d6.jpg?v=1788921299","url":"https:\/\/voomisupply.com\/products\/sgs-39177-square-end-mill-0-125in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
