It features a 3\/4 inch cutting diameter paired with a 1\/2 inch straight-cylindrical shank, allowing it to run in standard 1\/2 inch chuck capacity drills without sacrificing cutting size. The 118-degree split point starts on contact and reduces walking, while the cobalt construction handles the heat generated when drilling cast iron, alloy steel, and carbon steel. Right-hand spiral flutes clear chips efficiently throughout the 3-1\/8 inch flute length.\u003c\/p\u003e\n\u003cp\u003eThis Series 190C bit is built for general-purpose metal drilling in both shop and field environments. The reduced shank design makes it practical for portable drilling rigs and corded hand drills where chuck capacity is limited to 1\/2 inch. Primary workpiece materials include cast iron and steel. Secondary applications cover alloy steel, carbon steel, and cast iron in fabrication, maintenance, and mechanical contracting work. Machinists, millwrights, ironworkers, and general maintenance trades reach for this bit when cutting diameter needs to exceed the available chuck size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inch cutting diameter with 1\/2 inch reduced shank for use in standard 1\/2 inch chucks\u003c\/li\u003e\n  \u003cli\u003eCobalt tool material provides heat resistance for drilling ferrous metals and hard alloys\u003c\/li\u003e\n  \u003cli\u003e118-degree split point reduces drill walking and lowers entry thrust\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flutes with regular helix promote consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003e6 inch overall length with 3-1\/8 inch flute length for reach in deep-hole applications\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0012 inches for controlled hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in portable drilling applications with 1\/2 inch chuck capacity drills.

Ensure the shank is fully seated and the chuck is properly tightened before operation. Secure the workpiece firmly to prevent rotation during drilling. Follow applicable shop safety standards and wear appropriate eye protection when drilling metal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0012 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Required\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 190C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: 53448\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51737005850930,"sku":"53448","price":85.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7f8dbce7e8b7972df55941cec955559.jpg?v=1788783076","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-53448-cobalt-drill-bit-3-4-in-reduced-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
