Built from high speed steel with a coated finish, this bit measures 0.1875 inches in diameter with a 118-degree standard point angle. The spiral flute geometry and web-thinned, tapered web configuration promote efficient chip evacuation and reduced thrust during entry. At 5.75 inches overall length with a 3.375-inch flute, the taper length body reaches deeper holes than a jobber-length bit without requiring an extension. The tanged shank seats securely in compatible drill chucks and taper-shank holders. Right-hand cutting with a regular spiral makes it a direct-fit for standard drill presses and hand drills used by machinists, pipefitters, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThe 49512 is suited for drilling alloy steel, carbon steel, cast iron, and tool steel in production and maintenance environments. The taper length design is commonly specified when a jobber-length bit lacks the reach for deep-hole work in flanges, structural members, or heavy-wall pipe fittings. The general-purpose grade and coated finish extend tool life under moderate feed rates and speeds without requiring coolant-through capability. Single-piece packaging makes it a practical bench stock item for tool cribs and service vans.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction for durability across ferrous metal applications\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eSpiral flute design promotes chip clearance during deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends cutting life compared to uncoated HSS bits\u003c\/li\u003e\n  \u003cli\u003eTanged shank for positive drive in taper-shank holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, no coolant-through required — compatible with standard drill setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in alloy steel, carbon steel, cast iron, and tool steel applications.

Secure the workpiece firmly before drilling to prevent movement and ensure bit alignment. Verify that the drill press or hand drill is powered down and the bit is fully seated and locked in the chuck before starting. Follow applicable shop safety standards and use appropriate eye protection and cutting fluid for the material being drilled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.375 inches (60.32 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Tanged\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: +0.0000 to -0.0007 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron, Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 255AN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance Grade\u003c\/strong\u003e: General Purpose\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: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 49512\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51748328767794,"sku":"49512","price":18.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/787e773df971f467c373b1eb0a272f07_01935645-6bac-4a82-a285-e1d8fc12f42a.jpg?v=1788892499","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-49512-taper-length-drill-bit-3-16-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
