Built from cobalt high speed steel (HSS-Co), this bit handles the heat and abrasion demands of ferrous materials where standard HSS tooling falls short. The 130-degree split point reduces walking and lowers thrust, making it well suited for production drilling without a center punch. The right-hand spiral flute geometry and R-thinned web configuration promote efficient chip evacuation and extend tool life in repetitive cycle operations. At 0.18 inches (wire size 15, 4.57 mm) diameter, it covers a commonly specified hole size in machined and fabricated steel components.\u003c\/p\u003e\u003cp\u003eThis bit is intended for use in screw machine operations, CNC drilling centers, drill presses, and hand-held power tools where a stub-length geometry is preferred for rigidity. The short flute length of 1.125 inches and overall length of 2.5625 inches reduce deflection in close-tolerance applications. It is suited for production shops, maintenance machinists, and industrial service technicians working with steel and alloy steel workpieces. The straight-cylindrical shank fits standard drill chucks without adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high speed steel construction for heat resistance in ferrous material drilling\u003c\/li\u003e\n\u003cli\u003e130-degree point angle with R-thinned web reduces thrust and prevents walking\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length provides increased rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 2-flute regular spiral for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks directly\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0 to -0.018 mm for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length drill bit for drilling steel and alloy steel; compatible with any standard drill chuck or collet accepting a straight-cylindrical shank at 0.18 inches diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or technician familiar with rotary cutting tools. Ensure the chuck or collet is fully tightened and the workpiece is securely fixtured before beginning the cut. No coolant-through capability is present on this bit; apply cutting fluid externally when drilling harder alloy steels to manage heat. Inspect the cutting edges for wear before each use and replace if chipping or dulling is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.18 inches (wire size 15, 4.57 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt High Speed Steel\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 Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 10180005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730071191858,"sku":"10180005","price":42.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a5f100eab2084451e06d6a8ec96ca21.jpg?v=1788711212","url":"https:\/\/voomisupply.com\/products\/osg-10180005-screw-machine-drill-bit-0-18-in-cobalt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
