Built from high speed steel with a bright uncoated finish, this bit is engineered for heavy-duty drilling applications in steel alloy and similar ferrous materials. It features a 135-degree split point for fast, self-centering starts without a center punch, and a parabolic flute geometry that efficiently evacuates chips and reduces heat buildup during deeper cuts. The 2-3\/8 inch overall length fits standard drill chucks on benchtop drill presses, hand drills, and CNC equipment. It is part of the Series 150DH line, designed for production-volume use by machinists, maintenance mechanics, and fabricators.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for precision drilling in steel alloy workpieces in both production shop and maintenance environments. The straight-cylindrical shank seats securely in standard three-jaw chucks. The parabolic flute design makes it particularly effective in deeper holes where chip packing and heat are common concerns. The 135-degree split point eliminates the need for a center punch on flat stock and reduces walking on curved surfaces. It is sold individually, with a minimum order quantity of 12 units, making it practical for stocking in tool cribs or service vans that demand consistent small-diameter hole quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 40 at 0.0980 inches decimal diameter with a tight tolerance of -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for self-centering starts and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes fast chip evacuation and cooler cutting in deeper holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for heavy-duty use in steel alloy materials\u003c\/li\u003e\n  \u003cli\u003eTapered web with web-thinned geometry reduces drilling resistance and improves bit longevity\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with cutting fluids on a wide range of steels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Series 150DH OEM-style jobber length drill bit for use with standard three-jaw chucks accepting a 0.0980-inch straight-cylindrical shank.

Secure the shank fully in the chuck and verify runout before drilling into the workpiece. Use an appropriate cutting fluid or coolant when drilling steel alloy to extend bit life and maintain tolerance. Avoid excessive feed pressure on small-diameter bits, as it is the leading cause of breakage in wire-gauge sizes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0980 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\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\u003eFlute Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.375 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: 0.0980 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0000 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\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\u003eSeries\u003c\/strong\u003e: 150DH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 69040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51749429739826,"sku":"69040","price":47.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d1acd31143818fb06ef870e62f78359.jpg?v=1788905997","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-69040-jobber-drill-bit-wire-40-hss-135","provider":"Voomi Supply","version":"1.0","type":"link"}
