The bit features a 25\/32-inch cutting diameter with a 1\/2-inch straight-cylindrical shank, allowing it to be chucked in standard 1\/2-inch capacity drill chucks despite the larger cutting diameter. Constructed from high speed steel with a coated finish, it carries a 118-degree standard point angle suited for general-purpose drilling. With a 6-inch overall length and a 3-1\/8-inch flute length, this right-hand cut bit handles a wide range of production and field drilling tasks.\u003c\/p\u003e\n\u003cp\u003eThe 55450 is used in residential and light commercial applications where a larger bore diameter is required but only a 1\/2-inch chuck is available. Typical install scenarios include rough carpentry, pipe penetration prep, structural steel work, and general fabrication. The two-flute spiral design with regular helix provides adequate chip evacuation in both ferrous metals and wood. This bit is cataloged under Chicago-Latrobe Series 190 and is sized for general-purpose portable drilling without coolant.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduced shank design: 25\/32-inch cutting diameter with 1\/2-inch shank fits standard 1\/2-inch chucks\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry in wood, carbon steel, alloy steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003eCoated finish for improved wear resistance and surface protection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute spiral design promotes consistent chip clearing\u003c\/li\u003e\n  \u003cli\u003eNo coolant required — suitable for portable and handheld drilling operations\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 equipped with a 1\/2-inch capacity chuck.

Confirm the drill press or handheld drill is powered off and unplugged before changing bits. Apply steady, consistent feed pressure and allow the flutes to clear chips naturally — forcing the bit increases heat buildup and shortens tool life. No coolant is required for typical applications, but reducing feed rate when drilling harder alloy steels will extend bit 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: 25\/32 inches (0.7812 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: 2.25 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: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eCoolant Required\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Portable Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 190\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.47 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: 55450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51755255103794,"sku":"55450","price":58.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6a518c7d7a87e23621130ed2ca9ab5f.jpg?v=1788952715","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-55450-reduced-shank-drill-bit-25-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
