It features a 1\/4 inch cutting diameter, a 3\/4 inch length of cut, and a 2-1\/2 inch overall length with a 1\/4 inch shank diameter. The tool is ground from micrograin carbide stock and finished with a diamond coating, which improves surface finish and extends tool life in ferrous and non-ferrous cutting. The 30-degree helix angle and spiral flute geometry promote efficient chip evacuation and reduce cutting forces during slotting, profiling, and peripheral milling operations.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual mills where tight tolerances and fine surface finishes are required. The stub-length configuration provides added rigidity, making it appropriate for shallow-to-medium-depth cuts in steel, aluminum, and similar machinable materials. It is a single-end tool with a right-hand cut and right-hand flute direction, consistent with standard spindle configurations on most vertical machining centers. The centercutting capability allows plunge entry without a pre-drilled pilot hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for wear resistance and dimensional stability\u003c\/li\u003e\n\u003cli\u003eDiamond finish coating for improved surface finish and extended tool life\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle with spiral flute geometry for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard spindle compatibility\u003c\/li\u003e\n\u003cli\u003eStub length for increased rigidity in precision milling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4 inch shank square end mill compatible with collet chucks, end mill holders, and shrink-fit tooling systems accepting 1\/4 inch shank tooling on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank to the full recommended insertion depth in the holder to minimize runout and prevent tool pull-out under cutting loads. Verify tool projection and runout with a dial indicator before beginning a new operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\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: Diamond\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.00 \/ -0.02 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 7020\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 70201116\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51742690869554,"sku":"70201116","price":295.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ea6f006bc40b842664019e16920e4f9b.jpg?v=1788838869","url":"https:\/\/voomisupply.com\/products\/osg-70201116-square-end-mill-1-4-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
