Built from micrograin carbide, it delivers the hardness and edge retention required for demanding cuts in ferrous and non-ferrous metals, high-temperature alloys, and cast materials. The four-flute configuration with a 30-degree helix angle provides a balance of chip evacuation and surface finish quality. This is a centercutting tool, allowing plunge entry as well as conventional peripheral and slot milling. Shank diameter is 0.375 inches and overall length is 2.5 inches, making it suited for standard toolholders in CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in machine shop environments where close-tolerance milling of ferrous alloys, stainless steels, non-ferrous metals, superalloys, and similar materials is required. Primary workpiece material codes listed include H, K, M, N, P, and S, covering high-temperature alloys, cast iron, stainless, non-ferrous, steel, and special materials. The regular-length geometry and straight cylindrical shank make it compatible with standard ER collets, milling chucks, and hydraulic toolholders. It is a single-end tool intended for machine tool use by machinists and tool-and-die professionals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for high hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design with 30-degree helix angle for chip control and finish quality\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge milling and slot entry\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic vibration during cutting\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with cutting fluid on compatible workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with straight cylindrical toolholders including ER collet chucks, hydraulic chucks, and milling chucks accepting a 0.375-inch shank diameter.

Ensure the spindle is fully stopped and the machine is powered down or in a safe-stop state before installing or removing the end mill from the toolholder. Verify toolholder runout is within acceptable limits before beginning cuts, as excess runout will accelerate edge wear and reduce dimensional accuracy. Always consult the applicable speeds-and-feeds data for the specific workpiece material before engaging the cut.\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eLength of Cut\u003c\/strong\u003e: 1.0 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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\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: +0.00000 \/ -0.00035 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H, K, M, N, P, S\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: 30141\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51751888159026,"sku":"30141","price":80.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/676b9cc03a4c53099f46eb00df1104ae.jpg?v=1788924578","url":"https:\/\/voomisupply.com\/products\/sgs-30141-square-end-mill-21-64-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
