It features a 25\/32 inch cutting diameter with a 1\/2 inch Weldon shank, allowing it to seat securely in standard half-inch chucks and side-lock holders without slipping. The bit is manufactured from high speed steel with a coated finish for added wear resistance. A 118-degree split point reduces walking at startup and lowers thrust requirements compared to a conventional point. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling operations.\u003c\/p\u003e\n\u003cp\u003eThe 52450 belongs to the CHICAGO-LATROBE 190F series and is suited for general-purpose portable drilling on job sites and in shop environments. The reduced shank design makes a larger diameter bit accessible through smaller chuck capacities, a practical solution when drilling alloy steel, carbon steel, cast iron, or wood with a half-inch drive tool. The 3-number-of-flats Weldon shank prevents rotation in the holder under torque loads common to larger diameter bits. Licensed electricians, pipefitters, ironworkers, and general contractors typically reach for this bit when oversized holes are needed with standard portable equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e25\/32 inch cutting diameter (0.7812 inch decimal) with a tolerance of +0.0000 to -0.0012 inches\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch Weldon shank with 3 flats for positive torque transfer in side-lock holders\u003c\/li\u003e\n  \u003cli\u003e118-degree split point for reduced walking and lower feed pressure at entry\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended service life\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eGeneral-purpose rating suitable for 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 portable drilling applications with 1\/2 inch side-lock or Weldon-style chuck systems.

Ensure the drilling tool is powered off and unplugged before inserting or removing the bit. Apply cutting fluid when drilling ferrous metals to reduce heat buildup and extend bit life. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point geometry is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 25\/32 inch (0.7812 inch)\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\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, 3 flats\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 Length Type\u003c\/strong\u003e: Reduced shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 190F\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: 0.5 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: 52450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51727420031282,"sku":"52450","price":62.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a09e90d707075c064bf08301be23d2c_2590de2d-962c-48a0-a079-d72a057e51d5.jpg?v=1788677686","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-52450-reduced-shank-drill-bit-25-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
