It has a 21\/64-inch (0.3281-inch) mill diameter, a 1-inch length of cut, and a 3\/8-inch straight cylindrical shank. Overall length is 2-1\/2 inches. The two-flute spiral design paired with a TiN finish gives this tool strong chip evacuation and wear resistance. Micrograin carbide construction supports tight tolerances and consistent performance across repeated cuts. It is centercutting, allowing plunge entry as well as conventional peripheral milling. Right-hand cut and right-hand flute orientation are standard for this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations on a broad set of workpiece materials, including cast iron, non-ferrous metals, stainless steel, carbon steel, and high-temperature alloys, as indicated by its primary material codes H, K, M, N, P, and S. The regular length profile fits standard knee mills, CNC machining centers, and toolroom mills where a compact reach is appropriate. It is typically purchased by machinists, tool-and-die shops, and maintenance shops handling general-purpose metal removal work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiN finish for improved lubricity and extended tool life\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling without a pre-drilled entry\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth cutting action and chip flow\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches for precise fitment\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral configuration for efficient chip clearance in a range of materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill suitable for standard 3\/8-inch collet or end mill holders on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Secure the shank in a clean, properly sized collet or end mill holder torqued per the holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, as excessive runout will accelerate edge wear and affect dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 21\/64 inch (0.3281 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiN\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3\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: 39341\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51727194423602,"sku":"39341","price":82.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a672e10575632fa4a0bdefb6762549c9.jpg?v=1788674565","url":"https:\/\/voomisupply.com\/products\/sgs-39341-square-end-mill-21-64-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
