At 1 inch in diameter with a 15-inch overall length and an 11-inch spiral flute, this bit reaches depths that standard-length drill bits cannot. The uncoated HSS construction provides reliable performance across a broad range of workpiece materials. A web-thinned, tapered web design reduces thrust load at the point and improves chip evacuation. This bit is intended for use by machinists, maintenance technicians, and fabrication professionals working on production or job-shop equipment.\u003c\/p\u003e\n\u003cp\u003eThis extra length drill bit is suited for through-hole and deep-hole drilling in applications where extended reach is required, such as structural fabrication, mechanical assembly, and maintenance drilling. Primary workpiece materials include aluminum, magnesium, copper, nickel, synthetic materials, and titanium. Secondary workpiece materials include stainless steel, steel, nickel alloys, malleable iron, hardened steel, high strength bronze, magnesium alloy, and reinforced plastics. The straight-cylindrical shank seats in standard drill chucks and milling machine spindles with a 1-inch capacity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 inch diameter with 15-inch overall length for deep-hole reach\u003c\/li\u003e\n  \u003cli\u003e11-inch spiral flute length promotes efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eUncoated high speed steel construction for general-purpose metalworking\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting thrust and improves point penetration\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle suitable for a wide range of metals\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction with regular spiral; Series 1511 designation\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for dimensional consistency\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 drill presses, lathes, and milling machines equipped with a 1-inch straight-cylindrical shank capacity.

Secure the straight-cylindrical shank firmly in a properly sized drill chuck or collet before operation. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve hole quality, particularly when drilling stainless steel or nickel alloys.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1 inch\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 inch\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1511\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 15xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\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: 5999811\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51710281646386,"sku":"5999811","price":337.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5edfec512f0da12b0de14d0e92d81d6_39c04595-f541-4c20-a2fa-9edbb59d83ef.jpg?v=1788465146","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999811-extra-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
