It carries a Titanium Nitride (TiN) coating that reduces friction and extends cutting life in demanding production environments. The bit features a 130-degree point angle with R-thinned web geometry, which lowers thrust force at entry and improves self-centering on curved or angled surfaces. At 3-9\/16 inches overall length with a 2-1\/8-inch flute length, it fits standard drill chucks used in machine shops, maintenance operations, and metalworking trade applications. This bit is sold individually and suited for machinists, maintenance mechanics, and trade professionals working with ferrous metals.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for blind hole drilling, cross-hole drilling, through drilling, and self-centering operations on steel and alloy steel workpieces. The straight-cylindrical shank measures 3\/16 inch in diameter, making it compatible with standard drill press chucks, hand drills, and CNC drill heads that accept straight-shank tooling. The regular spiral flute promotes chip evacuation in short-to-medium depth holes typical of production and maintenance drilling tasks. This bit is a strong fit for job shops, MRO operations, and trade professionals who need a reliable cobalt bit for everyday steel drilling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction with TiN coating for extended tool life in steel and alloy steel\u003c\/li\u003e\n\u003cli\u003e130-degree point angle reduces walking and improves entry accuracy\u003c\/li\u003e\n\u003cli\u003eR-thinned web lowers thrust and supports self-centering without a center punch in many applications\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute promotes chip clearance in blind and through-hole drilling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eSeries 1500 high-performance grade for demanding production and maintenance use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct sourcing option for cobalt jobber-length drill bits in the 0.1500 to 0.2000 decimal inch size range, compatible with any drill press, hand drill, or CNC machine that accepts a 3\/16-inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by trade machinists and maintenance professionals using standard drill chuck equipment. Secure the shank fully in the chuck before operation and confirm chuck key removal before powering on. Use appropriate cutting fluid when drilling steel to manage heat, especially in blind-hole applications where chip evacuation is limited. Always wear appropriate eye protection and follow applicable shop safety procedures when operating drilling equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11\/64 inches (0.1719 inches \/ 4.37 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-9\/16 inches (3.5625 inches \/ 90.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-1\/8 inches (53.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eCoolant Through\u003c\/strong\u003e: No\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: 1500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 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: 15171905\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737650069810,"sku":"15171905","price":50.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a03c2f67d24880a4f149bc53922ecba3.jpg?v=1788791868","url":"https:\/\/voomisupply.com\/products\/osg-15171905-cobalt-jobber-drill-bit-11-64-in-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
