Built with 4 helical flutes and a centercutting geometry, this end mill handles both plunge cutting and peripheral milling in a single tool. The mill diameter measures 0.2030 inches (13\/64 inch nominal) with a 0.2500-inch cylindrical shank. Length of cut is 0.6250 inches (5\/8 inch), and overall length is 2.5 inches. The 38-42 degree helix angle promotes efficient chip evacuation and reduces heat buildup during extended cutting passes.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in vertical machining centers, CNC knee mills, and manual milling machines where a small-diameter, close-tolerance cutter is required. Its solid carbide construction makes it appropriate for hardened steels, stainless alloys, cast iron, and non-ferrous materials. The cylindrical shank seats directly into standard ER or end mill holders sized for 1\/4-inch shank tooling. Machinists, tool-and-die makers, and CNC operators working in job shops, maintenance facilities, and production environments are the typical end users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003e4 helical flutes for improved surface finish and chip flow\u003c\/li\u003e\n\u003cli\u003e38-42 degree helix angle reduces cutting forces and heat generation\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance over high-speed tool steel\u003c\/li\u003e\n\u003cli\u003e0.2500-inch cylindrical shank fits standard 1\/4-inch end mill and collet holders\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker geometry for clean finish cuts in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for standard 1\/4-inch cylindrical shank end mill holders and ER collet systems accepting a 0.2500-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down or placed in E-stop before changing tooling. Confirm the shank is fully seated and the set screw or collet nut is torqued according to the toolholder manufacturer specifications. Inspect runout with a dial indicator after seating to verify concentricity before initiating a cutting program.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.2030 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 13\/64 inch\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (Decimal)\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (Fractional)\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eHelix Angle\u003c\/strong\u003e: 38-42 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 14788473\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51736971444530,"sku":"14788473","price":44.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e7ddb139d189a882c17a95287955adb.jpg?v=1788782523","url":"https:\/\/voomisupply.com\/products\/accupro-14788473-square-end-mill-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
