Built on OSG Series 7020, this stub-length end mill features a 1\/16 inch cutting diameter with a 3\/16 inch length of cut and a 30-degree helix angle. The diamond finish coating improves surface hardness and lubricity, reducing heat buildup during aggressive cuts. With only 2 flutes and a micrograin carbide substrate, the tool maintains rigidity and edge integrity in tight-tolerance slots, pockets, and contours at small diameters. It is centercutting and configured for right-hand cut with right-hand spiral flutes, making it compatible with standard CNC machining center spindles.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for precision slot milling, pocketing, and contouring operations on CNC machining centers and high-speed mills. The 1\/8 inch shank diameter fits standard collet systems, and the 1\/2 inch extended reach makes it practical for accessing deeper features without excessive tool deflection. It is intended for machinists and tooling specialists working on tight-tolerance components in aerospace, mold-making, medical device, and general precision machining environments where small-diameter tooling and dimensional accuracy are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/16 inch cutting diameter with plus 0.00 \/ minus 0.02 mm diameter tolerance for tight dimensional control\u003c\/li\u003e\n  \u003cli\u003eSolid carbide micrograin substrate provides rigidity and wear resistance at small diameters\u003c\/li\u003e\n  \u003cli\u003eDiamond finish reduces friction and extends tool life in demanding cut conditions\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle with spiral flute geometry promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry directly into the workpiece\u003c\/li\u003e\n  \u003cli\u003eStub length classification minimizes deflection when working at this diameter scale\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/8 inch collet systems on CNC machining centers and high-speed milling machines.

Secure the 1\/8 inch shank in a properly sized collet or tool holder and torque to the machine manufacturer specification. At this diameter, runout control is critical — verify total indicator runout before cutting. Do not exceed the recommended speed and feed parameters for the workpiece material and coating type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.0560 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1\/2 inch\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\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\u003eFinish\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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: plus 0.00 \/ minus 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: 0.02 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 70200316\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728555147570,"sku":"70200316","price":149.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/356efcf0d99998d584b4716ede55c9ad.jpg?v=1788693243","url":"https:\/\/voomisupply.com\/products\/osg-70200316-square-end-mill-1-16-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
