Built from high speed steel (HSS) with a bright\/uncoated finish, this bit measures 25\/64 inch (0.3906 inches) in diameter with a 7-inch overall length and a 4-3\/8-inch parabolic flute. The 135-degree split point promotes self-centering entry without a center punch, reducing walking and improving hole accuracy. A tapered web configuration and web-thinned geometry reduce cutting resistance and help clear chips efficiently during through-hole operations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production and maintenance machining environments where general-purpose metal drilling is required. The parabolic flute profile — rated at a 6xD flute-to-diameter ratio — supports efficient chip evacuation in deeper drilling passes. Applicable materials include alloy steel, carbon steel, stainless steel, hardened steel, tempered steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, copper, graphite, magnesium, magnesium alloy, nickel, titanium, and titanium alloy. It is used in manual drill presses, CNC drill cycles, and handheld drilling operations where a straight shank bit is appropriate.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e25\/64 inch (0.3906 inches) diameter, straight shank — no chuck adapter required\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for self-centering, walk-free starts on metal surfaces\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry at 6xD ratio for deep-hole chip clearance\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for heavy-duty grade performance\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces thrust and cutting load\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — compatible with cutting fluid application\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut; no coolant-through capability\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 straight-shank drill chucks accepting 25\/64 inch shanks.

Secure the straight shank firmly in a keyed or keyless drill chuck rated for the intended RPM and feed rate. De-energize and lock out the machine before changing or inspecting the bit. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish; this bit does not support coolant-through 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: 25\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.3906 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4-3\/8 inches\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\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\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3906 inches (25\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC91P\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: 5997232\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51712746422578,"sku":"5997232","price":55.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/493f31ed2c78d8c96911c7c32cd9970a_4020ed6e-185d-4029-b7a8-b6f39492890b.jpg?v=1788488342","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997232-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
