Built from high speed steel with a bright\/uncoated finish, it features a 135-degree split point and a parabolic flute geometry with web thinning for faster chip evacuation and reduced thrust. The straight shank measures 9\/32 inches in diameter, matching the 9\/32-inch drill diameter. Overall length is 6-1\/4 inches with a flute length of 3-7\/8 inches. This bit is intended for professional machinists and metalworking trades requiring a reliable general-purpose taper length drill.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for right-hand cut drilling operations in both production and job-shop environments. Its parabolic flute profile and web-thinned split point make it effective in difficult-to-machine materials including stainless steel, hardened steel, titanium, cast iron, aluminum, brass, bronze, copper, carbon steel, alloy steel, magnesium, nickel, and graphite. The taper length body provides additional reach compared to a standard jobber bit, making it useful in applications where clearance depth or reach is a factor. It conforms to ANSI standards and is classified as a heavy-duty grade bit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces walking and lowers required drilling thrust\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes efficient chip removal at higher feed rates\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration improves cutting performance in tough alloys\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides heat resistance during continuous metal drilling\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish allows easy visual inspection for wear or damage\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant heavy-duty grade rated for self-centering tool applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible 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.

Secure the shank fully in the chuck before operation and verify chuck tightness. Always wear appropriate eye protection and secure the workpiece before drilling. Follow shop safety procedures and applicable ANSI machining standards when operating at rated speeds and feeds for the target material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC91P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 9\/32 inches (0.2812 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\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\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-7\/8 inches\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\u003eOverall Length\u003c\/strong\u003e: 6-1\/4 inches\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: 9\/32 inches (0.2813 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.083 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: 5997448\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51708984787250,"sku":"5997448","price":39.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/493f31ed2c78d8c96911c7c32cd9970a_93d7cde6-3d10-4f3e-8d43-af6a21fca1e3.jpg?v=1788449600","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997448-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
