It measures 3\/8 inch (0.3750 inch decimal) in diameter with a 5-7\/16 inch overall length and a 3-5\/8 inch flute length. The bit features a 130-degree R-thinned point for improved self-centering and reduced thrust in hard materials. A titanium nitride (TiN) coating extends surface hardness and wear resistance. This bit is intended for use by machinists, maintenance technicians, and metalworking tradespeople who require consistent performance in production or field drilling operations.\u003c\/p\u003e\u003cp\u003eThe OSG 15375005 is suited for drilling blind holes, cross holes, and through holes in steel and alloy steel workpieces. Its regular spiral flute geometry promotes efficient chip evacuation in these materials. The straight-cylindrical shank fits standard 3\/8 inch drill chucks and collet holders found on drill presses, CNC machines, and hand drills. This bit fits within OSG Series 1500 and is appropriate for right-hand-cut applications where a standard jobber length reach is sufficient for the workpiece depth.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction provides heat resistance and durability when drilling hardened and alloy steels\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and extends tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003e130-degree R-thinned point promotes self-centering and reduces walking on hard surfaces\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with tapered web configuration improves chip flow and reduces drill deflection\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank is compatible with standard 3\/8 inch chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eTwo-flute design balances cutting speed and chip clearance for metalworking applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use jobber drill bit for standard 3\/8 inch drill chucks and collet holders; suitable for use in drill presses, machining centers, and hand-held power drills where a straight-cylindrical shank bit is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this drill bit should be performed by a qualified machinist or technician familiar with proper tooling procedures. Ensure the drill chuck or collet is fully de-energized and the spindle is at a complete stop before inserting or removing the bit. Seat the shank fully into the chuck and verify runout before beginning any cut. Do not exceed the tool's rated speed range for the workpiece material being drilled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 9.53 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-7\/16 inches (5.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-5\/8 inches (92.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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 -0.022 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole, Cross Hole, Drilling, Self-Centering\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: 0.13 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: 15375005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730487279922,"sku":"15375005","price":121.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cefebfd883eda87f081617add0778b70.jpg?v=1788718317","url":"https:\/\/voomisupply.com\/products\/osg-15375005-cobalt-jobber-drill-bit-3-8-inch-130-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
