It features a Titanium Nitride (TiN) coating over a cobalt substrate, which extends tool life and reduces friction during cutting. The 130-degree point angle and R-thinned web geometry support self-centering entry and clean penetration into hard materials. At 6-5\/32 inches overall length with a 4-1\/16 inch flute length, this bit fits standard drill chucks and CNC setups alike. The 1\/2-inch straight-cylindrical shank provides secure tool holding. It is intended for use by machinists, tool-and-die shops, and maintenance technicians working on production or repair drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling blind holes, cross holes, and through holes in steel and alloy steel workpieces. The right-hand spiral flute with regular spiral type efficiently evacuates chips in typical shop and field conditions. The TiN coating makes it a practical choice when tool longevity matters across repeated drilling cycles in medium-to-hard ferrous materials. It is sold individually and sized for applications requiring a 0.4375 inch (7\/16 inch) bore diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction with Titanium Nitride (TiN) coating for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle with R-thinned web for self-centering and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch straight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eSuited for blind hole, cross hole, and self-centering drilling applications\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0 to -0.027 mm for precise bore sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber length drill bit in OSG Series 1500, suited for use in steel and alloy steel (material code P) drilling applications.

Secure the shank fully in the chuck or collet before operation and confirm tool runout is within acceptable limits. Do not exceed the recommended feed and speed parameters for cobalt tooling in the workpiece material being drilled. Inspect the cutting edges before each use and remove the bit from service if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/16 inches (0.4375 inches \/ 11.11 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-5\/32 inches (6.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4-1\/16 inches (4.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-25\/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\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\u003eDrill Bit Material\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 -0.027 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: 0.239 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 15437505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729168466226,"sku":"15437505","price":160.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/78ce53a7a1810b7ee43c2cc6b56c088a_9d304b16-2e51-4ed8-95ca-8dae7579b3fe.jpg?v=1788701268","url":"https:\/\/voomisupply.com\/products\/osg-15437505-cobalt-jobber-drill-bit-7-16-inches-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
