The bit measures 0.0210 inches in decimal diameter and 1 inch overall length, with a 1\/4-inch spiral flute and a straight-cylindrical shank of equal 0.0210-inch diameter. A 118-degree standard point with web thinning reduces thrust on entry and helps the bit start accurately without a center punch on most materials. Two regular-spiral flutes evacuate chips efficiently during through-hole drilling. This is a general-purpose, right-hand-cut bit suited for production or maintenance drilling by machinists, tool-and-die techs, and HVAC or electrical tradespeople who need small precision holes.\u003c\/p\u003e\n\u003cp\u003eWire gauge size No. 75 drill bits are used when close-tolerance small-diameter holes are required — common applications include pilot holes, tap-drill prep for miniature threads, orifice drilling, and instrument or panel work. The CHICAGO-LATROBE 44145 is rated for use in cast iron and steel as primary workpiece materials, making it appropriate for light ferrous metalworking, sheet metal fab shops, and precision maintenance environments. The oxide finish performs best with cutting oil applied to the workpiece. Series 150 designates Chicago-Latrobe standard jobber geometry conforming to DIN 338.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge No. 75 decimal diameter of 0.0210 inches for close-tolerance small-bore work\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with oxide coating for basic lubricity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point with web thinning for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eTwo regular-spiral flutes for consistent chip evacuation in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets accepting 0.0210-inch shanks\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 jobber length geometry — Series 150\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 drill press, hand drill, or CNC spindle equipped to hold a 0.0210-inch straight-cylindrical shank.

Power down and lock out the drill press or machine spindle before changing bits. Apply cutting oil to the workpiece when drilling ferrous metals to extend bit life and reduce heat buildup. Do not exceed the recommended feed rate for small-diameter bits, as wire gauge sizes are prone to breakage under side load or excessive feed pressure.\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. 75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0210 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1 inch\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: 0.0210 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 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: 0.1 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: 44145\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51735938236722,"sku":"44145","price":44.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1eca19afe150757905f09246344639f8_b4fc2b42-b26f-49fc-8cf1-047963fd1ba9.jpg?v=1788775004","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-44145-no-75-jobber-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
