Built to Series 1500 standards, it features a titanium nitride (TiN) coating over a cobalt substrate, delivering increased surface hardness and extended tool life in demanding production environments. The 130-degree split point uses an X-thinned web geometry to promote self-centering and reduce the thrust force needed to start a hole. Overall length is 3.0625 inches with a flute length of 1.625 inches. The straight-cylindrical shank measures 3\/16 inch in diameter. Machinists, tool-and-die technicians, and maintenance mechanics are the primary users of this bit.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling blind holes, cross holes, and through holes in steel and alloy steel workpieces. The regular spiral flute and right-hand cut make it compatible with conventional drill presses, CNC machining centers, and hand-held power drills. The TiN coating reduces friction and heat buildup during continuous production runs. No coolant-through capability is present, so flood coolant or cutting oil applied externally is the recommended cooling method when drilling ferrous materials at sustained feed rates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction with TiN coating for elevated heat and wear resistance in steel applications\u003c\/li\u003e\n\u003cli\u003e130-degree X-thinned point promotes self-centering and reduces walking on entry\u003c\/li\u003e\n\u003cli\u003eTapered web configuration with 2 regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, straight-cylindrical shank for standard drill chuck compatibility\u003c\/li\u003e\n\u003cli\u003eRated for blind hole, cross hole, and self-centering drilling operations\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 for use in steel and alloy steel workpieces as indicated by the P-category primary workpiece material code.

Ensure the shank is fully seated and the chuck is tightened securely before beginning a cut. Power down the machine and relieve all stored energy before changing bits. Apply an appropriate cutting oil or flood coolant externally, as this bit does not support coolant-through delivery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch \/ 3.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0625 inches (77.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.625 inches (41.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch\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: X-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: Regular Spiral\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\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: 0.018 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 15125005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731959120178,"sku":"15125005","price":34.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2ff3d46052850bdfb26147fe22c8efe.jpg?v=1788737251","url":"https:\/\/voomisupply.com\/products\/osg-15125005-cobalt-jobber-drill-bit-1-8-inch-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
