Built on the Series S638 platform, this single-end tool features a 1\/4 inch cutting diameter, a 5\/8 inch length of cut, and a 1\/4 inch straight-cylindrical shank with an overall length of 2 inches. Six spiral flutes with a variable helix geometry improve chip evacuation and reduce chatter during finishing and semi-finishing passes. The AlTiN coating provides heat resistance and extended tool life in ferrous materials and high-temperature alloys. This end mill is centercutting, allowing plunge entry. It is manufactured from micrograin carbide stock for edge sharpness and wear resistance.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual knee mills where a long-series, small-diameter tool is needed for reaching into pockets, slots, or stepped features. Typical applications include slot milling, profile milling, and contour work in steel, stainless steel, cast iron, and similar ferrous materials. The right-hand cut and right-hand flute orientation match standard spindle rotation on most vertical and horizontal machining centers. It is installed by machinists and CNC operators in job shops, aerospace, and general manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for superior edge retention and rigidity\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for thermal resistance and extended tool life in ferrous and high-temp alloy cutting\u003c\/li\u003e\n  \u003cli\u003e6-flute variable helix design reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eLong-series length of cut at 5\/8 inch provides reach for deeper pocket and slot work\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute orientation for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for CNC machining center and manual mill setups requiring a 1\/4 inch shank, 1\/4 inch diameter solid carbide square end mill in the SECO Series S638 long-series configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists and CNC operators using an appropriate collet, end mill holder, or hydraulic chuck rated for 1\/4 inch straight-cylindrical shanks. Verify runout at the spindle and holder before cutting to preserve edge geometry on a 6-flute tool. Ensure spindle is fully stopped and machine is in an e-stop or lockout condition before changing tooling. Follow shop speeds-and-feeds protocols for the specific workpiece material and machine spindle power.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End, Square\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\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: S638\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.060 to -0.060 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03115934\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558264275250,"sku":"03115934","price":101.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9e60b8dd76ed78d0de80234cc8705d8_b9b586e4-8215-4971-920e-8ed3358784cc.jpg?v=1786407817","url":"https:\/\/voomisupply.com\/products\/seco-03115934-square-end-mill-1-4-inch-6-flute-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
