With a 19\/32-inch (0.5938 inch) cutting diameter and a 1\/2-inch straight-cylindrical shank, this bit fits standard 1\/2-inch chuck equipment even though the cutting end is larger. The 118-degree split point starts on contact without a center punch and reduces walking on hard surfaces. Cobalt construction handles heat buildup better than standard high-speed steel, making it a dependable choice when drilling through tough ferrous metals.\u003c\/p\u003e\n\u003cp\u003eThe 53438 is suited for portable drilling operations on cast iron, steel, alloy steel, and carbon steel workpieces in fabrication shops, maintenance environments, and industrial job sites. The Series 190C design covers general-purpose drilling where a reduced shank allows a larger-diameter bit to run in a 1\/2-inch chuck. Licensed electricians, millwrights, pipefitters, and general maintenance mechanics commonly reach for this type of bit when drilling oversized holes without switching to a larger drill press setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material provides increased heat and wear resistance compared to standard HSS bits\u003c\/li\u003e\n  \u003cli\u003e118-degree split point reduces thrust and eliminates center-punch requirements on most metals\u003c\/li\u003e\n  \u003cli\u003eReduced shank design (1\/2-inch shank, 19\/32-inch cutting diameter) allows use in standard 1\/2-inch chucks\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix for consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003e2-flute configuration with 3-1\/8-inch flute length handles moderate hole depths\u003c\/li\u003e\n  \u003cli\u003eGeneral-purpose performance rating covers a wide range of ferrous workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style general-purpose replacement or direct-use cobalt drill bit compatible with any 1\/2-inch keyed or keyless drill chuck in portable or bench-mounted drilling equipment.

Secure the workpiece with a vise or clamps before drilling to prevent rotation and injury. Apply cutting fluid or coolant to extend bit life when drilling through hard alloy steels, even though the bit is rated for dry use. Inspect the cutting edges before each use and replace or resharpen if chipping or dullness is observed to maintain hole-diameter tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 19\/32 inches (0.5938 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches \/ 12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.25 inches (57.15 mm)\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eDrill Length Type\u003c\/strong\u003e: Reduced Shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 190C\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\u003eTool Application\u003c\/strong\u003e: Portable Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 53438\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51733149286706,"sku":"53438","price":76.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/810a585191417944449e2017319df3fa.jpg?v=1788751939","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-53438-cobalt-reduced-shank-drill-bit-19-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
