Built from high speed steel with a coated finish, it carries a 63\/64 inch (0.9844 inch) cutting diameter on a 1\/2 inch Weldon shank, allowing it to run in standard 1\/2 inch chucks even at this near-1-inch diameter. The 118-degree split point reduces walking on entry and lowers thrust force at the start of a cut. Overall length is 6 inches with a 3-1\/8 inch flute length, keeping the bit manageable in handheld or drill-press setups. Series 190F, right-hand cut, two-flute spiral design.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for portable drilling operations in fabrication shops, field service, and maintenance environments. Primary workpiece materials include wood, alloy steel, carbon steel, and cast iron. The Weldon shank with three flats prevents slippage under high torque loads, making it appropriate for larger-diameter holes where rotational force is significant. It is a practical choice for trades that drill oversize pilot holes, conduit knockouts in panels, or large-diameter clearance holes in structural steel or framing members.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e63\/64 inch cutting diameter (0.9844 inch decimal) on a reduced 1\/2 inch shank for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003e118-degree split point for reduced walking and lower entry thrust\u003c\/li\u003e\n  \u003cli\u003eWeldon shank with 3 flats prevents bit rotation under high torque\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended service life\u003c\/li\u003e\n  \u003cli\u003eTwo-flute regular spiral design promotes chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eGeneral-purpose rating covers wood, alloy steel, carbon steel, and cast iron\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 1\/2 inch Weldon-style chucks and end-mill holders.

Secure the Weldon shank fully into the chuck or holder, tightening the set screw against one of the three flats before operation. Ensure the workpiece is clamped or fixtured before starting a cut to prevent spinning. Follow applicable shop safety standards and manufacturer guidelines for drill speed selection based on workpiece material and bit diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 63\/64 inch (0.9844 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch \/ 12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 3\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)\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: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0012 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Portable Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Reduced Shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Wood\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron, Wood\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 190F\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: 52463\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51733805793586,"sku":"52463","price":84.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a09e90d707075c064bf08301be23d2c_aa082eac-2e9b-4d0d-a6e4-7808914e5380.jpg?v=1788759358","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-52463-reduced-shank-drill-bit-63-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
