The bit measures 0.0820 inches in diameter, matching wire gauge size 45, with an overall length of 4.25 inches and a parabolic flute length of 2.25 inches. The 135-degree split point is web-thinned and self-centering, reducing walking and thrust load at the start of each hole. The bright, uncoated finish suits dry or wet cutting environments. Machinists, tool-and-die technicians, and trade professionals installing equipment or fabricating mounting hardware reach for this size when working with close-tolerance pilot holes or full-diameter bores in thin stock.\u003c\/p\u003e\n\u003cp\u003eThis bit is built for right-hand cutting in a standard drill press, CNC machine, or hand-held electric drill. Its parabolic flute geometry, rated at a 6xD flute-to-diameter ratio, clears chips efficiently in deep-hole applications. The QC91P series is rated for heavy-duty use across a broad material list including carbon steel, stainless steel, alloy 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 straight shank fits standard chucks without adapters, and the non-threaded shank seats securely in both keyed and keyless chuck styles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point with web thinning for self-centering entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry at 6xD ratio for efficient chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for heavy-duty cutting across 20-plus material types\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish compatible with dry cutting and most cutting fluids\u003c\/li\u003e\n  \u003cli\u003eStraight, non-threaded shank fits standard keyed and keyless chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI standards for taper length drill bit geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct addition for any setup requiring a wire gauge 45 (0.0820-inch diameter) taper length drill bit with a straight shank in rotating drill equipment.

Always ensure the workpiece is clamped or fixtured securely before drilling. Wear appropriate eye protection and confirm spindle speed is set to the correct RPM for the material and bit diameter before starting the cut. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged, as a worn split point increases thrust load and reduces hole accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0820 inches (Wire Size 45)\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\u003c\/strong\u003e: 2.25 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 Point\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\u003eShank Type\u003c\/strong\u003e: Straight, Non-Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0820 inches\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\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: 0.042 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: 5997132\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51701603303730,"sku":"5997132","price":24.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/493f31ed2c78d8c96911c7c32cd9970a_95e004ed-16bd-4e09-90d2-2d855d446786.jpg?v=1788402314","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997132-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
