It features a 135-degree split point that reduces walking and allows self-centering entry without a center punch. The parabolic flute geometry promotes faster chip evacuation and reduced heat buildup during deeper drilling operations. With an overall length of 4.25 inches and a flute length of 2.25 inches, this bit is designed for applications that require reach beyond what a jobber-length bit provides. It is suited for use by machinists, maintenance technicians, sheet metal workers, and trade professionals working in demanding production or field environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for general-purpose heavy-duty drilling across a broad range of materials, including alloy steel, carbon steel, stainless steel, hardened steel, tempered steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, copper, nickel, titanium, titanium alloy, magnesium, magnesium alloy, and graphite. The taper length body suits work where standard jobber bits lack sufficient reach, such as drilling through structural members, deep flanges, or stacked material. The straight cylindrical shank fits standard drill chucks without adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eParabolic flute profile with web thinning for fast chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration adds rigidity while maintaining cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated HSS finish compatible with cutting oils and standard coolants\u003c\/li\u003e\n  \u003cli\u003e6xD flute-length-to-diameter ratio provides extended reach versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for dimensional accuracy and geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use taper length drill bit for standard 3-jaw drill chucks accepting a 3\/32 inch straight cylindrical shank, suitable for benchtop drill presses, handheld drills, and milling machine setups across general metalworking applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall this bit into a properly sized drill chuck and tighten securely with a chuck key before operation. Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Apply cutting fluid when drilling ferrous metals, stainless steel, or titanium to extend bit life and control heat. Inspect the cutting edges for wear or chipping before each use and replace the bit if the split point or flute geometry is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC91P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 3\/32 inch (0.0938 inch)\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\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\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: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered with web thinning\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\u003eShank Diameter\u003c\/strong\u003e: 3\/32 inch (0.0938 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 6xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Self-Centering, General Purpose\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: 0.042 pounds\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: 5997472\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51691133731122,"sku":"5997472","price":20.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/493f31ed2c78d8c96911c7c32cd9970a_4b5b610d-0a31-4e76-a485-f68344fffa46.jpg?v=1788280676","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997472-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
