Manufactured from high speed steel with a bright uncoated finish, this bit measures 0.2280 inches in diameter (wire size No. 1) and carries a standard 118-degree drill point angle. The overall length is 3.875 inches with a 2.625-inch flute length, making it a compact, versatile bit suited for production and maintenance drilling. A web-thinned, tapered web design reduces thrust at entry. Licensed HVAC, plumbing, and mechanical contractors rely on this type of bit when removing seized fasteners or drilling pilot holes in ferrous components during equipment service.\u003c\/p\u003e\n\u003cp\u003eThe 44471 is built for drilling cast iron and steel in residential and commercial maintenance scenarios. The left-hand spiral flute configuration is particularly useful when extracting broken or stripped fasteners, as the cutting action applies counter-clockwise torque that can back out damaged screws during drilling. The straight-cylindrical shank is compatible with standard three-jaw drill chucks. This bit is part of Chicago-Latrobe Series 150L, a general-purpose line engineered for consistent performance across a range of ferrous workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand cut spiral flute for counter-clockwise drilling and fastener extraction\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with bright uncoated finish\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces drilling thrust and improves chip clearance\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard three-jaw chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eNo. 1 wire size (0.2280 inches) with tight diameter tolerance of -0.0007 to 0.0000 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or service bit compatible with standard three-jaw drill chucks accepting a 0.2280-inch straight-cylindrical shank.

Always secure the workpiece before drilling and confirm the drill is set to reverse rotation to engage the left-hand cut. Wear appropriate eye protection and ensure cutting speed is appropriate for the workpiece material and bit diameter. Do not force the bit through hardened material grades beyond the general-purpose rating of high speed steel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2280 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\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2280 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0332 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: 44471\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51734761832754,"sku":"44471","price":20.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8711a7c85be6739c9d910ae01a810660.jpg?v=1788766731","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-44471-jobber-length-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
