Coated with titanium nitride (TiN) for extended tool life and reduced friction, it features a 130-degree R-thinned point that improves self-centering and reduces thrust in harder materials. The bit measures 5\/8 inch (0.6250 inch) in diameter with an overall length of 7-27\/32 inches and a spiral flute length of 5-3\/16 inches. With a straight-cylindrical shank at 3\/4 inch diameter, it seats securely in standard drill chucks and tool holders. This is a Series 1500 tool built for professional metalworking environments.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling blind holes, cross holes, and through-holes in steel and alloy steel workpieces in production, maintenance, and fabrication settings. The right-hand cut and regular spiral flute geometry handle chip evacuation efficiently in ferrous materials. Typical users include machinists, tool and die workers, maintenance mechanics, and metalworking tradespeople who need consistent, repeatable hole quality in harder stock. The tapered web configuration and R-thinned point reduce walking on entry, making it practical for both drill press and hand-held power tool applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction with TiN coating for durability in ferrous and alloy steel materials\u003c\/li\u003e\n\u003cli\u003e130-degree R-thinned point for improved self-centering and reduced thrust\u003c\/li\u003e\n\u003cli\u003eSpiral flute with tapered web configuration for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 2-flute design suited for blind holes, cross holes, and through-hole drilling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 3\/4 inch diameter for secure chuck engagement\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design — compatible with standard external coolant or dry cutting setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling steel and alloy steel workpieces.

Secure the shank fully in the chuck before operation and verify runout is within acceptable limits for the application. Always wear appropriate eye protection and follow applicable shop safety procedures when operating drill presses or handheld power tools. Do not exceed the recommended RPM and feed rates for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inch \/ 15.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7-27\/32 inches (199 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5-3\/16 inches (131 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2-1\/32 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\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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 -0.027 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: 0.605 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: 15625005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727801844018,"sku":"15625005","price":405.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/78ce53a7a1810b7ee43c2cc6b56c088a_ec4d0785-115a-4240-878c-512fc8202d0c.jpg?v=1788682653","url":"https:\/\/voomisupply.com\/products\/osg-15625005-cobalt-drill-bit-5-8-inch-tin-130-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
