It features a 0.5313 inch (17\/32 inch) diameter, a 135-degree split-point tip for self-centering starts without a center punch, and a parabolic flute geometry that efficiently evacuates chips at a 6xD flute-to-diameter ratio. The bright, uncoated finish suits general-purpose applications where coating is not required. With an overall length of 8 inches and a flute length of 4-3\/4 inches, this bit provides the reach needed for deeper bores in production and maintenance environments. It carries ANSI standards compliance and is rated for general-purpose, heavy-duty use.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in metalworking, fabrication, and maintenance applications across residential and commercial settings. The straight shank and standard 17\/32 inch shank diameter make it compatible with most drill chucks and drill press setups. The parabolic flute design and web-thinned, tapered web configuration make it particularly effective when drilling into materials that generate significant chip load. Machinists, tool and die technicians, and maintenance professionals working in shops or in the field will find this bit appropriate for production runs and repair work alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering starts, reducing walk on hard or curved surfaces\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry with 6xD ratio for efficient chip evacuation in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces thrust requirements on harder materials\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for heavy-duty, general-purpose metalworking\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for general-purpose use across a broad material range\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant taper length design provides extended reach over jobber-length bits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe PRECISION TWIST DRILL 5997219 QC91P series is compatible with 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 workpieces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and operated by machinists and maintenance technicians using standard drill presses, CNC machines, or hand-held power drills equipped with an appropriately sized chuck. Secure the straight shank firmly in the chuck before use and verify that the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid or coolant for the specific material being drilled to extend tool life, noting that this bit does not have coolant-through capability. Inspect the cutting edges and web area before each use and replace the bit if chipping or excessive wear is detected.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5313 inches (17\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches (214 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4-3\/4 inches (140 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5313 inches (17\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\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\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\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: 0.5 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: 5997219\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51700357857586,"sku":"5997219","price":141.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/493f31ed2c78d8c96911c7c32cd9970a_d63dcad7-39b2-46cc-a452-fe5c089ea458.jpg?v=1788389354","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997219-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
