Built from high-speed steel with a bright, uncoated finish, this bit features a 135-degree split point that starts on contact and reduces walking without a center punch. The parabolic flute geometry clears chips aggressively, making it well suited for steel alloy workpieces where heat and chip packing are concerns. At 15\/64 inches in diameter with a 3-7\/8-inch overall length, it fits standard drill chucks and drill presses used daily in trade and fabrication work. The Series 150DH designation indicates a heavy-duty grade intended for production drilling environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is used in residential and commercial trade applications wherever 15\/64-inch holes are required in steel alloy and similar ferrous materials. Typical scenarios include HVAC bracket fabrication, electrical panel knockouts, plumbing hanger installations, and general sheet-metal or structural steel work. The straight-cylindrical shank fits 3-jaw chucks on handheld drills, drill presses, and magnetic drills. Right-hand cut rotation is standard for all conventional drill equipment. The 2-flute, web-thinned design reduces thrust force and extends cutting life in repetitive drilling tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point starts on contact and eliminates walking on flat or curved metal surfaces\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes fast chip evacuation and reduces heat buildup in steel alloy\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction lowers drilling thrust and extends bit life\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles the heat generated in production and repetitive drilling\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows easy visual inspection of cutting edge condition\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank is compatible with standard 3-jaw chucks across hand drills and drill presses\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber-length drill bit for use in any standard 3-jaw chuck accepting a 15\/64-inch straight-cylindrical shank, suitable for drilling steel alloy and similar ferrous materials in trade fabrication and service work.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove drill bits only with the tool unplugged or the drill press powered down and the chuck key removed from the chuck. Secure the workpiece with a vise or clamps before drilling to prevent rotation and injury. Apply cutting fluid or oil when drilling steel alloy to extend bit life and reduce heat. Inspect the cutting edges before each use and replace the bit if chipping or dullness is evident, as a damaged split point increases thrust force and reduces hole accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 15\/64 inches (0.2344 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 15\/64 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\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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 68915\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51737457066290,"sku":"68915","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/800ba2a9e475f5d1ec3a291a71e00fe1.jpg?v=1788788800","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-68915-jobber-drill-bit-15-64-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
