Built to Series 150 standards and conforming to DIN 338, this bit features a 118-degree standard point angle, a regular spiral flute with web-thinned geometry, and a straight-cylindrical shank. Overall length is 4.0 inches with a flute length of 2.75 inches. The web-thinned, tapered web configuration reduces thrust during entry and improves chip evacuation. Licensed trades and metalworking professionals choose this bit for general-purpose drilling in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThe 44174 is designed for right-hand cutting in cast iron and steel workpieces. Its 2-flute spiral design handles both ferrous and general shop materials across a range of applications including fabrication, maintenance repair, and light production drilling. The straight-cylindrical shank accepts standard 3-jaw drill chucks found on bench drills, hand drills, and magnetic-base drills. No coolant-through capability is present, making this bit suited for dry or externally lubricated setups typical in general shop use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter D diameter: 0.2460 inches with a tight tolerance of -0.0007 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry in cast iron and steel\u003c\/li\u003e\n  \u003cli\u003eOxide coating provides a layer of surface hardness and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces cutting thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eRegular 2-flute spiral geometry suits a wide range of ferrous workpiece materials\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 dimensional standards for consistent fitment and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber length drill bit compatible with any standard 3-jaw drill chuck that accepts a 0.2460-inch straight-cylindrical shank.

Secure the straight-cylindrical shank firmly in a properly sized drill chuck before use and verify chuck key is removed before powering on the tool. Apply appropriate cutting fluid or lubricant when drilling steel to extend tool life and maintain dimensional tolerance. 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 Size (Letter)\u003c\/strong\u003e: D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2460 inches\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: Oxide\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0 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: 0.2460 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 inches\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\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0388 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: 44174\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51747376726322,"sku":"44174","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1eca19afe150757905f09246344639f8_e1d931ca-f19e-4caa-818d-4e6019804c29.jpg?v=1788879161","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-44174-letter-d-jobber-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
