The bit carries an 11\/16-inch cutting diameter with a reduced 1\/2-inch straight-cylindrical shank, allowing it to seat in standard 1\/2-inch chucks. The 118-degree split point geometry promotes fast penetration and reduces walking on entry without a center punch. Built from cobalt tool steel and finished with a protective coating, the 53444 handles elevated heat generated during cutting in ferrous materials. Flute length measures 3-1\/8 inches with a 6-inch overall length. This is a two-flute, right-hand cut bit in the Series 190C line.\u003c\/p\u003e\n\u003cp\u003eThe 53444 is suited for general-purpose portable drilling in cast iron, steel, alloy steel, and carbon steel. Machinists, maintenance technicians, fabricators, and field tradespeople use reduced shank bits when the required hole diameter exceeds the capacity of a 1\/2-inch chuck. The cobalt construction makes this bit a practical choice where high-speed steel bits wear prematurely due to work hardening or sustained heat buildup. It is packaged and sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool steel construction resists heat and wear in ferrous metal drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree split point reduces entry walking and lowers thrust requirement\u003c\/li\u003e\n  \u003cli\u003eReduced shank design — 11\/16-inch cutting diameter fits 1\/2-inch chucks\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute spiral flute configuration clears chips efficiently\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends surface life and reduces friction during cuts\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length with 3-1\/8-inch flute length suits most portable drilling depths\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any 1\/2-inch keyed or keyless drill chuck. Primary workpiece materials are cast iron and steel; secondary compatible materials include alloy steel, carbon steel, and cast iron. Rated for general-purpose tool performance in portable drilling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the reduced shank fully into the chuck jaws before tightening to prevent slippage and runout. Always wear eye protection and secure the workpiece before drilling. When drilling hard ferrous materials, use the lowest practical RPM and apply consistent feed pressure to avoid overheating the cutting edge. No coolant system is required for this bit, but intermittent relief of the bit from the cut helps dissipate heat during extended use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11\/16 inches (0.6875 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.25 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\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\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\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\u003eTool Application\u003c\/strong\u003e: Portable Drilling\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: 0.4 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: 53444\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51747526213938,"sku":"53444","price":77.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c5b3fdacd6e9ea13e74199b8e693f8e.jpg?v=1788881902","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-53444-reduced-shank-cobalt-drill-bit-11-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
