It is built for right-hand rotation with a regular spiral flute and a straight cylindrical shank measuring 0.2500 inches in diameter. The 135-degree point geometry reduces the thrust needed to start a hole and is web-thinned to improve chip clearance. This bit is suited for drilling operations in steel, aluminum, and other non-ferrous materials. It is installed and used by machinists, maintenance technicians, and trade professionals requiring a precise small-diameter drill in general-purpose applications.\u003c\/p\u003e\u003cp\u003eThe 5997108 is designed for general-purpose drilling in production and maintenance environments. Its wire gauge 40 size makes it a go-to for tapping prep, instrument work, and small fastener clearance holes in steel and non-ferrous stock. The 2.3750-inch overall length and 1.3750-inch flute length provide adequate reach for typical bench and drill press work without sacrificing rigidity at this small diameter. The series QC21P designation places it within a standardized jobber-length family built to ANSI specifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 40 with 0.0980-inch decimal diameter for precise small-bore drilling\u003c\/li\u003e\n\u003cli\u003e135-degree standard point with web thinning reduces walking and lowers required thrust\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction handles steel, aluminum, and non-ferrous workpieces\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish is compatible with a wide range of cutting fluids\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with tapered web promotes chip evacuation in through-hole applications\u003c\/li\u003e\n\u003cli\u003eStraight shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit suitable for use in handheld drills, drill presses, and CNC drilling operations where a straight-shank wire gauge 40 bit is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed and operated by machinists, maintenance technicians, and trade professionals using standard drill chucks rated for the 0.2500-inch shank diameter. Secure the shank fully in the chuck before operation and confirm the chuck key is removed prior to starting the machine. Use appropriate cutting fluid when drilling steel to extend tool life and maintain hole quality. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 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\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 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\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC21P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Aluminum, Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5997108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51699567493426,"sku":"5997108","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14c3de90969c6378087aaa7d157a7434_5d796840-6339-41ed-ac71-8f823bbc983d.jpg?v=1788377569","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997108-jobber-drill-bit-40-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
