With a 0.250-inch mill diameter, 1-inch length of cut, and 4-inch overall length, this tool delivers accurate material removal in a compact long-reach profile. The micrograin carbide substrate and TiCN coating work together to extend tool life in abrasive and hard-material applications. A 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces, making it well-suited for slotting, profiling, and peripheral milling tasks performed by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for use in CNC machining centers and manual knee mills where a 1\/4-inch shank diameter is required. The long length-of-cut configuration supports deeper slot milling and side-milling passes without tool changes. Its centercutting geometry allows plunge entry directly into the workpiece. Typical applications include milling of steel alloys, stainless steel, cast iron, and similar ferrous materials in both production-run and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiCN finish improves surface hardness and reduces friction during cutting\u003c\/li\u003e\n  \u003cli\u003e40-degree spiral flute helix angle promotes aggressive chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003e4-flute configuration balances chip load and surface finish quality\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute geometry compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills accepting a 1\/4-inch round shank end mill holder or collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolroom practices. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the end mill from its holder or collet. Verify collet runout is within acceptable tolerance before beginning a cut, as excessive runout accelerates edge wear on a tool of this diameter. Consult the machine manufacturer and applicable shop safety standards for proper clamping torque and tool-stick-out guidelines.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.250 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: 1.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12183479\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731906593074,"sku":"12183479","price":59.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/15fa3c59b0b15f41ae14d0dc9f43d170.jpg?v=1788736400","url":"https:\/\/voomisupply.com\/products\/accupro-12183479-square-end-mill-1-4-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
