Built from high speed steel (HSS), it carries a bright, uncoated finish suited for a wide range of ferrous and non-ferrous materials. The cutter measures 0.125 inches in diameter with a 0.75-inch length of cut, a 0.1875-inch straight shank, and an overall length of 3.125 inches. Four spiral flutes with a 30-degree right-hand helix provide efficient chip evacuation and consistent surface finishes in slotting, profiling, and peripheral milling applications.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard collet and tool holders accepting a 3\/16-inch straight shank. Its long-series classification and double-end design make it a cost-effective choice for production shops running light-to-moderate material removal on milling machines and CNC machining centers. Typical applications include slot cutting, step milling, and contour work in aluminum, mild steel, plastics, and similar machinable materials where an HSS cutter is appropriate.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design extends usable tool life before replacement\u003c\/li\u003e\n  \u003cli\u003e4 right-hand spiral flutes at a 30-degree helix angle for efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides toughness across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — ready for use as supplied or compatible with field coating processes\u003c\/li\u003e\n  \u003cli\u003eLong-series length classification for added reach in deeper setups\u003c\/li\u003e\n  \u003cli\u003eStraight shank fits standard collets and end mill holders without modification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank replacement end mill compatible with collet chucks, end mill holders, and milling machine spindles accepting a 3\/16-inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Secure the shank fully within the collet or holder to the manufacturer-recommended engagement depth before tightening. Inspect the collet and holder bore for wear or contamination prior to clamping. Always bring the spindle to a full stop before changing tooling, and verify runout with a dial indicator when tight tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.125 inches (3-1\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eSingle or Double End\u003c\/strong\u003e: Double End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 851\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 851-0125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693400883506,"sku":"851-0125","price":36.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b593b05999c38f8a15a925f3190ec2f.jpg?v=1788311830","url":"https:\/\/voomisupply.com\/products\/value-collection-851-0125-square-end-mill-1-8-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
