Built from cobalt with a gold oxide coating, this bit delivers the heat resistance and wear durability required for hard-material applications. The 135-degree split point promotes self-centering entry, reducing walking and the need for a center punch on most surfaces. At 4-3\/4 inches overall length with a 3-7\/16 inch spiral flute, it fits standard drill chucks and handles depths typical of jobber-length work. This bit is suited for use by machinists, maintenance techs, and fabricators working with tough ferrous metals.\u003c\/p\u003e\n\u003cp\u003eThe 011522 is intended for drilling alloy steel and similar hard ferrous materials in industrial maintenance, fabrication, and machine shop environments. The straight-cylindrical shank at 11\/32 inch diameter seats securely in keyed or keyless chucks. The web-thinned, tapered web configuration reduces thrust load during entry, making it practical for both drill press and hand-drill applications where consistent hole quality in hard stock is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction with gold oxide coating for heat resistance and extended tool life in hard metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for self-centering, walk-free entry without a center punch\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust and improves chip clearance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for efficient material evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty grade rated for alloy and alloy steel workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit jobber-length drill bit for use in standard 11\/32 inch chuck-compatible drill presses, CNC drilling setups, and handheld power drills within the T1C series lineup.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or trained maintenance personnel familiar with proper drill bit seating and speed-feed selection for cobalt tooling. Ensure the chuck is fully tightened and the workpiece is securely clamped before operation. Apply appropriate cutting fluid when drilling hard alloy steels to manage heat buildup and extend bit life. Inspect the cutting edge and web condition before each use and replace if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 11\/32 inches (0.3438 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-7\/16 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\u003eFlute Type\u003c\/strong\u003e: Spiral (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\u003eShank Diameter\u003c\/strong\u003e: 11\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel\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: T1C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.56 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: TRIUMPH TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 011522\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRIUMPH TWIST DRILL","offers":[{"title":"Default Title","offer_id":67911205224754,"sku":"011522","price":23.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e1894e8436e2cf0f3e939746239b04f.jpg?v=1791206413","url":"https:\/\/voomisupply.com\/products\/triumph-twist-drill-011522-cobalt-drill-bit-11-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
