Built to Series 1511 specifications, this bit features a 1\/4 inch diameter, a 118-degree standard point angle, and a bright uncoated finish. The 15-inch overall length and 11-inch flute length give machinists, pipefitters, and maintenance technicians the reach needed to drill through thick structural members, deep castings, and assemblies with obstructed access. Web-thinned geometry reduces thrust and improves chip evacuation during the cut.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling in aluminum, magnesium, copper, nickel, titanium, and synthetic materials as primary workpiece materials. It also performs in secondary applications involving stainless steel, nickel alloy, hardened steel, malleable iron, high strength bronze, magnesium alloy, and reinforced plastics. The straight cylindrical shank accepts standard drill chucks without a reduction sleeve. Right-hand spiral flutes with a regular spiral type make this a general-purpose tool appropriate for machine shop, mechanical contracting, and field maintenance work where extended reach is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e15-inch overall length provides extended reach for deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003e11-inch flute length promotes chip evacuation over the full depth of cut\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle compatible with a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces drilling thrust and entry force\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with bright uncoated finish for general-purpose use\u003c\/li\u003e\n  \u003cli\u003eTwo-flute right-hand spiral design with straight cylindrical 1\/4 inch shank\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose extra length drill bit compatible with any standard drill chuck or press accepting a 1\/4 inch straight cylindrical shank.

Reduce feed rate when drilling harder secondary materials such as stainless steel or hardened steel to avoid overheating the uncoated HSS cutting edge. Apply cutting fluid or lubricant appropriate to the workpiece material to extend tool life. Allow the bit to clear chips frequently when drilling the full depth of the flute length.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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-Cylindrical\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 15xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1511\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\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: 5999817\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693821985074,"sku":"5999817","price":75.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/859ed864a7f3c84e81bad631702c9720.jpg?v=1788317824","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999817-extra-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
