With a 0.1969-inch cutting diameter, a 0.7874-inch length of cut, and a 4-flute configuration, this end mill delivers clean square shoulders and flat-bottom features in demanding machining environments. The 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces. The WXL coating provides enhanced wear resistance for extended tool life in production settings. This tool is a single-end, center-cutting design intended for use in CNC machining centers and manual mills operated by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slot milling, peripheral milling, and profiling operations in shop and production environments. The 0.2362-inch shank diameter fits standard collets and end mill holders common in light to medium-duty machining setups. The micrograin carbide substrate supports high-speed cutting with tight tolerances. Applications include mold and die work, part profiling, and precision contouring in both prototype and production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.1969-inch cutting diameter with 0.7874-inch length of cut for small-feature milling\u003c\/li\u003e\n  \u003cli\u003e4-flute geometry for improved surface finish and material removal rate\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes efficient chip flow and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eWXL coating delivers enhanced wear resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction maintains edge integrity at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock solid carbide square end mill fitting any CNC or manual mill equipped with a collet or end mill holder accepting a 0.2362-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth and torque the retention mechanism per the machine and toolholder manufacturer specifications. Verify runout with a dial indicator before beginning the cut, as excessive runout accelerates edge wear and reduces surface finish quality on small-diameter tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1969 inches (5 mm)\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: 0.7874 inches (20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 inches (6 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 60 mm\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: WXL\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\u003eVariable Helix\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\u003ePackage Dimensions\u003c\/strong\u003e: 2.65 inches L x 0.5 inches H x 0.45 inches W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.045 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 37420004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732740997426,"sku":"37420004","price":149.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/03aeaa0383091d0c86ad16d7b81f6b36_3ce47890-2a6d-42ee-9f08-ec608379f87b.jpg?v=1788746198","url":"https:\/\/voomisupply.com\/products\/osg-37420004-square-end-mill-0-1969-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
