It carries a 7\/8 inch (0.8750 inch) cutting diameter with a 1\/2 inch straight-cylindrical shank, allowing it to run in standard 1\/2 inch drill chucks without requiring a larger spindle. The 118-degree split point starts on contact without walking, reducing setup time on cast iron and steel. A spiral flute geometry and coated finish support heat resistance and chip evacuation during continuous drilling operations. This bit is part of the Series 190C-TN line and is suited for use by machinists, pipefitters, ironworkers, and maintenance technicians who need a reliable reduced shank geometry in the field or on the floor.\u003c\/p\u003e\n\u003cp\u003eThe 53656 is built for portable drilling applications on primary workpiece materials including cast iron and steel, with secondary compatibility covering alloy steel and carbon steel. The reduced shank design makes it practical when the drill chuck capacity is limited to 1\/2 inch but a larger bore diameter is required. With a 6 inch overall length and 3-1\/8 inch flute length, it handles moderate-depth holes without excessive deflection. Right-hand cut direction is standard for use with conventional forward-rotating drills and drill presses.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for improved heat and wear resistance in ferrous metal drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree split point reduces thrust and eliminates center punch requirement on most metals\u003c\/li\u003e\n  \u003cli\u003eReduced shank (1\/2 inch) fits standard 1\/2 inch chucks while cutting a 7\/8 inch diameter bore\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends tool life in cast iron, alloy steel, and carbon steel applications\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral design with regular helix promotes efficient chip clearance\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0012 inches ensures consistent, close-tolerance holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for general-purpose portable drilling in cast iron, steel, alloy steel, and carbon steel.

Always power down and de-energize the drill or press before securing the bit in the chuck. Confirm chuck jaw engagement is fully seated on the 1\/2 inch shank before operation. Do not use this bit in SDS or spline-drive chucks without an appropriate adapter, as the straight shank requires a keyed or keyless chuck interface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/8 inch (0.8750 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\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\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eCoolant Required\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 190C-TN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 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: 53656\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":52127026446642,"sku":"53656","price":130.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87f98e80c41f705df4eb069c4dbd0b13_dd6ef3a1-cbe9-4b9a-813d-dd0b224e1d65.jpg?v=1790088728","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-53656-reduced-shank-drill-bit-7-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
