Built from high speed steel with a bright\/uncoated finish, it features a 135-degree split point that self-centers on contact, reducing walking and the need for a center punch. The parabolic flute geometry and web-thinned, tapered web construction promote fast chip evacuation during deep-hole drilling. At 19\/64 inch (0.2969 inches) in diameter with a 4-inch flute length and 6-3\/8-inch overall length, this bit handles taper-length applications where a standard jobber bit falls short. Licensed trade professionals and machinist-level technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for general-purpose metalworking in both shop and field environments. The parabolic flute design and split point make it effective in interrupted cuts and on curved surfaces. The QC91P series targets professionals who need reliable, repeatable hole quality in production or maintenance contexts. Material compatibility spans a broad spectrum including alloy steel, carbon steel, hardened steel, tempered steel, stainless steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, copper, titanium, titanium alloy, magnesium, magnesium alloy, nickel, and graphite.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering starts without a center punch\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry accelerates chip clearance in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust requirements and extends tool life\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles a broad range of metals including hardened and stainless steels\u003c\/li\u003e\n  \u003cli\u003eTaper length body provides extra reach beyond standard jobber length\u003c\/li\u003e\n  \u003cli\u003eANSI-standard straight shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and direct fitment for applications requiring a 19\/64 inch straight-shank taper length drill bit conforming to ANSI standards.

Ensure the drill press, hand drill, or CNC spindle is fully stopped and secured before changing bits. Verify chuck jaws are clean and that the straight shank is fully seated and tightened before operation. For coolant-sensitive setups, note that this bit does not support through-coolant delivery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 19\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.2969 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 Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2969 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose, Heavy-Duty Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC91P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.083 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: 5997225\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51698124914994,"sku":"5997225","price":43.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/493f31ed2c78d8c96911c7c32cd9970a_5905dcd0-c8bb-4f2e-beb8-a81c77f55d78.jpg?v=1788358075","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997225-taper-length-drill-bit-19-64","provider":"Voomi Supply","version":"1.0","type":"link"}
