Built from high speed steel with a bright, uncoated finish, this bit features a 0.2770 inch (Letter J) diameter, a 118-degree standard point angle, and a right-hand spiral flute configuration. The taper length body provides extra reach compared to jobber-length bits, making it well suited for applications where depth clearance is required. Web thinning reduces thrust and improves chip evacuation at the cutting tip. This bit belongs to the Series R55 line and conforms to ANSI standards.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is used in metalworking, fabrication, and maintenance applications across industrial and commercial settings. The straight shank fits standard drill chucks without additional adapters. Its general-purpose classification covers a broad spectrum of materials including carbon steel, alloy steel, stainless steel, aluminum, brass, bronze, cast iron, copper, nickel alloys, magnesium alloys, and reinforced plastics. Machinists, pipefitters, ironworkers, and maintenance technicians commonly reach for this bit when drilling through structural metal or mechanical components requiring a deeper hole than a standard-length bit allows.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.2770 inch diameter, equivalent to Letter J drill size\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a wide material range\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned tip for reduced thrust\u003c\/li\u003e\n  \u003cli\u003e3-7\/8 inch flute length with 6xD flute-to-diameter ratio for extended reach\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for consistent chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight shank with no threading for direct chuck mounting\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant Series R55 construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose taper length drill bit compatible with alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, cermet, copper, graphite, hardened steel, high strength bronze, magnesium, magnesium alloy, malleable iron, nickel, nickel alloy, reinforced plastic materials, and stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a standard drill press, hand drill, or milling machine chuck rated for a 0.2770 inch straight shank. Secure the shank fully in the chuck before operation and confirm chuck key is removed prior to starting. Apply appropriate cutting fluid when drilling hard metals such as stainless steel or hardened alloys to extend tool life and reduce heat buildup. Ensure workpiece is clamped or fixtured securely to prevent movement during drilling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2770 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.875 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\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\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: 0.2770 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eThreaded Shank\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R55\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\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: 6000459\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51704585716018,"sku":"6000459","price":33.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/479647ba23fbd9e6f114d277bf8570f3.jpg?v=1788423672","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000459-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
