With a 0.078-inch cutting diameter and a 0.39-inch length of cut, this tool is built for tight-tolerance work in ferrous and non-ferrous materials. The four-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. An AlTiN coating increases surface hardness and thermal resistance, extending tool life under high-speed cutting conditions. Micrograin carbide construction provides the rigidity and edge retention required for demanding machining environments. This end mill is single-end and centercutting, allowing plunge entry as well as standard peripheral milling.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers, manual mills, and precision production environments where small-diameter tooling is required. The 0.125-inch straight cylindrical shank fits standard collet systems and tool holders designed for 1\/8-inch shank tooling. It is commonly used in die and mold work, aerospace component machining, medical device manufacturing, and general precision part production where fine detail and close tolerances are essential. The extended length type designation and 2.5-inch overall length provide additional reach for deeper pocket or slot milling within its rated length-of-cut range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.078-inch cutting diameter with a tolerance of +0.000 to -0.001 inches for tight dimensional control\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand spiral geometry with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for increased heat resistance and extended tool life at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for superior rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with h6 tolerance for secure collet engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/8-inch collet chucks and compatible tool holders on CNC and manual milling machines that accept straight cylindrical shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the machine fully powered down and the spindle stopped. Ensure the collet and tool holder are clean and free of debris before seating the shank to the correct depth. Verify runout after installation using a dial indicator before beginning a cutting operation. Follow machine manufacturer guidelines and applicable shop safety standards for small-diameter carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.078 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.30 to 0.50 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\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.062 \/ -0.062 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.63 inches L x 0.5 inches W x 0.5 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.013 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: 02657\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51754503110962,"sku":"02657","price":57.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e925b7926288d93830cee7285dffea97_00d012b5-95d8-4376-85a5-5336666d87de.jpg?v=1788946090","url":"https:\/\/voomisupply.com\/products\/sgs-02657-square-end-mill-0-078in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
