Built from high speed steel with a bright uncoated finish, it features a 135-degree split point and a parabolic flute design that clears chips efficiently during drilling. The web-thinned, tapered web construction reduces thrust and improves hole entry in harder materials. At 3.25 inches overall length with a 2.125-inch flute length, it fits standard drill chucks via its straight-cylindrical shank. This is a heavy duty Series 150DH bit suited for production and maintenance drilling applications.\u003c\/p\u003e\u003cp\u003eThe 69021 is designed for drilling steel alloy and similar ferrous workpiece materials. Its parabolic flute geometry makes it well suited for applications where chip evacuation and cutting speed matter, such as fabrication shops, mechanical contractors, and industrial maintenance environments. The right-hand cut and split-point tip allow the bit to self-center without a pilot hole on flat or curved steel surfaces, reducing setup time on the job.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 21 at 0.1590 inches diameter for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point self-centers and reduces walking on steel surfaces\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes fast chip evacuation and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers drilling thrust and extends bit life\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction rated for heavy duty use in steel alloy materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish allows visual wear inspection during service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use jobber length drill bit for standard straight-shank drill chucks and compatible with any application requiring a wire size 21 diameter hole in ferrous or similar workpiece materials.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by trade professionals and machinists using standard keyed or keyless drill chucks rated for the 0.1590-inch shank diameter. Secure the shank fully in the chuck before operation and verify the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid or coolant when drilling steel alloy to manage heat and extend bit life. Inspect the cutting edges for wear before each use and replace the bit if chipping or dullness is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 21\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1590 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\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\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1590 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\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\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: 150DH\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 69021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51748862394674,"sku":"69021","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05f81fdc880a6a136b0c09c8256d2cef.jpg?v=1788899745","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-69021-jobber-drill-bit-wire-21-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
