The 1\/2-inch diameter bit features a 135-degree split point that is self-centering, reducing the need for a center punch and minimizing walking on hard surfaces. A gold oxide coating extends tool life by resisting heat and wear. The right-hand spiral flute geometry promotes efficient chip evacuation. This bit is built for professionals who regularly drill into alloy steel and similarly tough workpiece materials where standard high-speed steel bits fall short.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for fabrication shops, mechanical contractors, pipefitters, and industrial maintenance technicians who need reliable performance in ferrous metals and alloy steels. The T1C Series designation indicates a high-performance, heavy-duty grade intended for production drilling environments as well as field work. The web-thinned, tapered web configuration reduces cutting resistance and improves penetration rates on tough materials. The straight-cylindrical shank accepts standard 1\/2-inch drill chucks found on most corded and cordless drill presses and handheld tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction with gold oxide coating for extended heat resistance and tool life\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with self-centering geometry reduces walk without a center punch\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers cutting resistance in alloy and hard steels\u003c\/li\u003e\n  \u003cli\u003eRight-hand regular spiral flute promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 1\/2-inch shank fits standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty T1C Series grade rated for high-performance production and field use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/2-inch straight-cylindrical chuck drill presses and handheld power drills.

Secure the workpiece firmly before drilling to prevent movement and ensure a clean, accurate hole. Inspect the bit shank and chuck interface for debris before seating, and confirm the chuck is fully tightened before operation. Do not exceed the rated speed range for the material being drilled, and apply appropriate cutting fluid when drilling alloy steels to manage heat buildup.\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\/2 inch (0.5000 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 Length\u003c\/strong\u003e: 4-1\/2 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\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\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: 1\/2 inch\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 Application\u003c\/strong\u003e: Self-Centering\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: 1.46 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: 011532\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRIUMPH TWIST DRILL","offers":[{"title":"Default Title","offer_id":67918720958770,"sku":"011532","price":37.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0af0710fd10cc1fb350fa72cc6e95403.jpg?v=1791272558","url":"https:\/\/voomisupply.com\/products\/triumph-twist-drill-011532-cobalt-drill-bit-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
