Built from high speed steel with a coated finish, this bit features a 3\/16 inch (0.1875 inch) diameter, a 120-degree four-facet point, and a regular spiral flute configuration. The shorter screw machine length profile provides increased rigidity compared to jobber-length bits, reducing deflection and improving hole accuracy in production and repair environments. Web thinning reduces thrust force at entry, making this bit well suited for hand-feed and machine-feed drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The straight-cylindrical shank fits standard drill chucks without modification. Typical applications include production machining, maintenance and repair operations, and toolroom work where a compact, rigid bit is preferred over a longer jobber-length drill. The Series 1100 designation places this in OSG high-performance tooling and it is sold as a single unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/16 inch (0.1875 inch) diameter with tolerance of +0 to -0.018 mm for close-tolerance hole sizing\u003c\/li\u003e\n  \u003cli\u003e120-degree four-facet point angle for self-centering entry and reduced walking\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces drilling thrust and extends bit life\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (5xD flute-to-diameter ratio) provides superior rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for improved wear resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute spiral design for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard three-jaw chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production drill bit compatible with steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces as specified by the manufacturer for OSG Series 1100 tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by machinists or qualified trade professionals familiar with metalworking drill press, CNC, or hand-held power tool operation. Secure the straight-cylindrical shank firmly in the chuck and verify concentricity before drilling. Always power down and de-energize the machine before changing tooling. Do not exceed the recommended feed and speed parameters for the workpiece material to avoid premature wear or bit breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch \/ 4.76 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 70.00 mm (approximately 2.76 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 26.00 mm (approximately 1.02 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (approximately 0.236 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Four Facet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Aluminum, Aluminum Alloy, Aluminum Silicate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.018 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4 inches length, 0.25 inches width, 0.25 inches height\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 859547611\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736991990066,"sku":"859547611","price":67.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8fb891b805ec4cc06a9fbb22f4b9e646_cd007b19-06c8-4dcd-9444-528b6e81998b.jpg?v=1788782815","url":"https:\/\/voomisupply.com\/products\/osg-859547611-screw-machine-drill-bit-3-16-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
