The 135-degree split-point geometry reduces walking on entry and requires no center punch on most materials. At 2.375 inches overall length with a 1.375-inch flute, this is a standard jobber proportion suited for hand-held drills, drill presses, and CNC setups running small-diameter work. The web-thinned, tapered-web construction keeps cutting forces low and chip evacuation clean. Rated for general-purpose use with a heavy-duty grade designation, it carries ANSI specification compliance and is cataloged for high-temperature alloy applications.\u003c\/p\u003e\n\u003cp\u003eThis bit is sized at 0.0980 inches (decimal) and is a frequent choice for tapping pilot holes, instrument and panel work, sheet-metal drilling, and precision machining where wire-gauge sizing is specified. The straight cylindrical shank seats directly in standard Jacobs-style chucks and collet holders without adapters. The Series HX10-HX15-HX18 designation places it within a family of HSS jobber bits covering the 0.0500-to-0.1000-inch decimal range. Right-hand spiral flute cutting direction is compatible with standard forward-rotation spindles. Typical users include machinists, HVAC sheet-metal technicians, electricians, and maintenance trades working with small-diameter hole requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 40 wire gauge, 0.0980-inch decimal diameter — precise sizing for tap-drill and instrument work\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces drill walk and lowers thrust force on entry\u003c\/li\u003e\n  \u003cli\u003eHSS construction with bronze straw coating for lubricity and mild heat resistance\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web for improved chip clearance and reduced cutting resistance\u003c\/li\u003e\n  \u003cli\u003e1.375-inch flute length supports maximum drilling depth of 1.375 inches\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant, heavy-duty grade, Series HX10-HX15-HX18\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard Jacobs-style drill chucks and collet holders accepting a 0.0980-inch straight cylindrical shank.

At this diameter, use moderate feed pressure to avoid bit deflection or breakage — small HSS bits are susceptible to side-loading. Power down the drill or machine and confirm the spindle has stopped completely before changing bits. Cutting fluid or light oil is recommended when drilling hard or high-temp alloys to extend tool life.\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: No. 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0980 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.375 inches\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: 1.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral, 2 Flutes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bronze Straw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: High-Temp Alloy\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 by Diameter Ratio\u003c\/strong\u003e: 14xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HX10-HX15-HX18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.005 pounds\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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5995872\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51695140307250,"sku":"5995872","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28291d695eb6c90708270d4dadfdae7d_5bd64a0b-253f-4005-bde5-74d0e9da6597.jpg?v=1788331642","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5995872-no-40-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
