It carries a wire gauge size of 10, which corresponds to 0.1935 inches in decimal. The 135-degree split point reduces walking and allows self-centering entry without a center punch on most surfaces. A parabolic flute profile with web thinning and a tapered web configuration moves chips efficiently out of deep holes, reducing heat buildup and improving feed rates. The bright, uncoated finish suits applications where lubrication or coolant is applied at the point of cut. Overall length is 6 inches with a 3-5\/8 inch flute, giving it the extended reach typical of taper length geometry. This bit is installed by machinists, maintenance technicians, and tool-and-die professionals in production and repair settings.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling alloy steel, carbon steel, tempered steel, hardened steel, stainless steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, copper, graphite, magnesium, magnesium alloy, nickel, titanium, and titanium alloy. The taper length body is particularly useful when drilling through thicker stock or when a jobber length bit lacks the reach required for the application. Its straight shank fits standard drill chucks and collet systems without modification, making it compatible with benchtop drill presses, CNC machining centers, and handheld power drills equipped with a keyed or keyless chuck sized for a 0.1935 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 10 (0.1935 inches) taper length geometry for extended reach drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with self-centering action reduces the need for a center punch\u003c\/li\u003e\n  \u003cli\u003eParabolic flute profile with web thinning promotes fast, clean chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction rated for heavy-duty use across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish is compatible with standard cutting fluids and coolants\u003c\/li\u003e\n  \u003cli\u003eStraight shank at 0.1935 inches fits a wide range of standard chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI standards for drill bit geometry and tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style taper length replacement drill bit conforming to ANSI standards, compatible with standard drill chucks and collet systems accepting a 0.1935 inch straight shank.

Power down the machine and lock out the spindle before changing or inspecting the bit. Apply an appropriate cutting fluid or coolant for the material being drilled to extend tool life and improve hole quality. Avoid forcing the feed rate beyond what the material and machine setup can handle, as taper length bits are more susceptible to deflection than stub or jobber lengths under excessive side load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1935 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\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 Length\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 0.1935 inches\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreaded Shank\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\u003eTool Performance\u003c\/strong\u003e: General Purpose\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: 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\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: 5997964\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51694412792114,"sku":"5997964","price":34.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/493f31ed2c78d8c96911c7c32cd9970a_6fe3c868-f56d-4670-aa50-f19a87f414df.jpg?v=1788324247","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997964-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
