Built from high speed steel with a coated finish, it features a 21\/32 inch (0.6562 inch) cutting diameter paired with a 1\/2 inch Weldon shank, allowing it to chuck into standard 1\/2 inch capacity drill drivers and magnetic base drills without requiring a larger chuck. The 118-degree split point promotes self-centering at entry and reduces walking on flat or curved surfaces. With a 6 inch overall length and a 3-1\/8 inch flute length, the bit clears chips efficiently during deep-hole passes. Two spiral flutes in a regular helix configuration move material out of the cut while maintaining rigidity.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for portable drilling applications in metalworking, fabrication, and carpentry environments. The reduced shank design is particularly useful when a larger diameter bit must be used with a 1\/2 inch chuck. The three-flat Weldon shank prevents rotation in the chuck under torque, making it appropriate for production drilling, maintenance work, and field service on structural steel, cast iron, carbon steel, alloy steel, and wood. The Series 190F designation places it in CHICAGO-LATROBE's general-purpose coated HSS lineup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e21\/32 inch cutting diameter with a reduced 1\/2 inch Weldon shank for use in standard 1\/2 inch chucks\u003c\/li\u003e\n  \u003cli\u003eThree-flat Weldon shank prevents bit rotation under high-torque drilling conditions\u003c\/li\u003e\n  \u003cli\u003e118-degree split point for self-centering entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended wear life in general-purpose applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with two regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.0000 to -0.0012 inches for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose reduced shank drill bit compatible with portable drills and drill presses fitted with 1\/2 inch capacity chucks or Weldon-style tool holders.

Secure the Weldon shank fully into the chuck or tool holder, engaging the flats against the set screw to prevent slippage under load. Always power down the drill and disconnect power before changing bits. Use appropriate cutting fluid or lubricant when drilling ferrous metals to reduce heat buildup and extend tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 21\/32 inch (0.6562 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\u003eShank Type\u003c\/strong\u003e: Weldon (3-Flat)\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 Helix\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0012 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Portable Drilling, General Purpose\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: 0.4 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: 52442\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51748821729586,"sku":"52442","price":52.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a09e90d707075c064bf08301be23d2c_2291a296-f15a-473e-b845-70fdccdeb573.jpg?v=1788899023","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-52442-reduced-shank-drill-bit-21-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
