Built from high speed steel (HSS) with a bright uncoated finish, this bit features a 135-degree split point that self-centers on contact, reducing the need for a center punch. The parabolic flute geometry promotes efficient chip evacuation, especially in deep-hole applications. With a flute-to-diameter ratio of 6xD and a tapered web configuration, the 5997907 is suited for demanding production drilling where standard-length bits lack the reach.\u003c\/p\u003e\n\u003cp\u003eThis taper length drill bit is intended for professional machinists, tool-and-die tradespeople, and fabricators working in shop, industrial, and manufacturing environments. It is well suited for drilling into alloy steel, carbon steel, stainless steel, cast iron, aluminum, brass, bronze, copper, titanium, magnesium, and hardened or tempered steel. The straight shank and 0.1969-inch diameter make it compatible with standard drill chucks across a variety of drill press and handheld power tool setups. It conforms to DIN 340 standards for taper length drill geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering entry without a center punch\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design for fast, efficient chip removal in deep holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for heavy-duty drilling performance\u003c\/li\u003e\n  \u003cli\u003eTapered web with web thinning reduces thrust and cutting resistance\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with cutting fluids\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 340 taper length specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style taper length replacement or production drill bit for use in standard straight-shank drill chucks; compatible material applications include alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, copper, graphite, hardened steel, magnesium, magnesium alloy, malleable iron, nickel, stainless steel, steel, tempered steel, titanium, and titanium alloy per manufacturer specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or qualified tradespeople using a drill press, milling machine, or handheld power drill with a compatible chuck. Secure the straight shank fully in the chuck before operation and confirm the shank is locked to prevent slippage. Apply appropriate cutting fluid for the material being drilled to extend bit life and improve hole finish. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is visible.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1969 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 5.00 mm\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 Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length (Inch)\u003c\/strong\u003e: 3-27\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length (mm)\u003c\/strong\u003e: 87.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (Decimal Inch)\u003c\/strong\u003e: 5-13\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (mm)\u003c\/strong\u003e: 132.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1969 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 5.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length (mm)\u003c\/strong\u003e: 45.00 mm\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\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\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 Application\u003c\/strong\u003e: Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC91PM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 340\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: 5997907\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51711910838578,"sku":"5997907","price":38.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0523b926873e5beee59d705109f2aa85_4c695b59-33ec-4a6d-81d7-e3164872f0b6.jpg?v=1788481277","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997907-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
