Measuring 9\/64 inch (0.1406 inch decimal) in diameter with an overall length of 2-7\/8 inches and a flute length of 1-3\/4 inches, this bit is built for heavy-duty work in alloy and alloy steel. The 135-degree split point promotes self-centering entry and reduces walking on hard surfaces. A gold oxide coating adds surface hardness and heat resistance. Right-hand spiral flutes evacuate chips efficiently during extended drilling runs. Licensed tradespeople and maintenance machinists reach for this bit when standard high-speed steel tooling falls short.\u003c\/p\u003e\u003cp\u003eThe 011509 is suited for drilling alloy steel and similar hard metals in fabrication, maintenance, and mechanical service environments. The straight-cylindrical shank accepts standard three-jaw chucks on drill presses, hand drills, and right-angle drill attachments. The Series T1C designation places this bit in a heavy-duty, high-performance tier appropriate for production and repetitive drilling tasks where bit longevity and hole accuracy matter. It ships individually and is sold in a minimum quantity of one unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction with gold oxide coating for extended tool life in hard metals\u003c\/li\u003e\n\u003cli\u003e135-degree split point for self-centering entry on alloy and alloy steel workpieces\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration reduces thrust and improves chip clearance\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for reliable chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard three-jaw chucks without an adapter\u003c\/li\u003e\n\u003cli\u003eSeries T1C heavy-duty grade rated for high-performance drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber length drill bit compatible with any standard three-jaw chuck or drill press accepting a straight-cylindrical shank in the 9\/64 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists, HVAC technicians, plumbers, or electricians familiar with rotating tool safety. Secure the workpiece firmly before drilling and confirm chuck jaws are fully tightened. Match spindle speed to the workpiece material and bit diameter per standard machining tables. Do not apply excessive lateral force, as cobalt bits are harder but more brittle than standard high-speed steel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 9\/64 inch (0.1406 inch decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9\/64 inch\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 Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\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\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 011509\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRIUMPH TWIST DRILL","offers":[{"title":"Default Title","offer_id":67914841293106,"sku":"011509","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f51dadf5d11f845931048f310d1008b.jpg?v=1791251260","url":"https:\/\/voomisupply.com\/products\/triumph-twist-drill-011509-cobalt-drill-bit-9-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
