The bit measures 31\/32 inch (0.9688 inch decimal) in diameter with a 1\/2-inch straight-cylindrical shank, allowing it to run in standard 1\/2-inch chucks even at a larger cutting diameter. Overall length is 6 inches with a 3-1\/8-inch flute length. The 118-degree split-point tip starts on contact without a center punch and reduces walking on flat stock. Two right-hand spiral flutes clear chips efficiently during through-hole and blind-hole work. Tool material is cobalt, which retains hardness at elevated cutting temperatures better than standard HSS, making it well suited for abrasive or tough base materials.\u003c\/p\u003e\n\u003cp\u003eThe 53462 is built for portable drilling applications where a full-shank bit at this diameter would exceed chuck capacity. It is commonly used by machinists, maintenance technicians, pipefitters, and ironworkers drilling cast iron, carbon steel, alloy steel, and similar ferrous materials. The reduced 1\/2-inch shank fits corded drills, magnetic base drills, and drill presses equipped with standard 1\/2-inch keyless or keyed chucks. The Series 190C designation places this bit in a general-purpose cobalt line intended for production and field use across a broad range of steel grades and cast iron components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material retains cutting hardness at high temperatures for drilling tough ferrous alloys\u003c\/li\u003e\n  \u003cli\u003e118-degree split-point tip reduces thrust and eliminates center-punch requirement on flat workpieces\u003c\/li\u003e\n  \u003cli\u003eReduced 1\/2-inch shank allows use in standard 1\/2-inch chucks at a 31\/32-inch cutting diameter\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with two regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCoated finish for added wear resistance and reduced friction during drilling\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.0000 to -0.0012 inch for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in portable drills and drill presses fitted with 1\/2-inch chucks.

Secure the workpiece firmly before drilling and verify the chuck is tightened fully on the reduced shank to prevent slippage. Wear appropriate PPE including eye protection and cut-resistant gloves when handling and operating. Inspect the cutting tip for wear or chipping before each use and replace the bit if the split point shows significant degradation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 31\/32 inch (0.9688 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\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\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\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\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0012 inch\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: 0.7 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: 53462\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51749732614450,"sku":"53462","price":128.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/441b219c6f6404fbcbfc1be4f95b71e5.jpg?v=1788909701","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-53462-reduced-shank-cobalt-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
