The 135-degree split point geometry reduces walking and cutting force on entry, making it well suited for production and repetitive drilling tasks. The web-thinned, tapered web design improves chip evacuation and reduces thrust load. Right-hand spiral fluting with a regular helix handles chip clearing in a range of ferrous workpiece materials. This bit is installed and used by machinists, millwrights, and maintenance technicians across industrial and commercial job sites.\u003c\/p\u003e\n\u003cp\u003eThe 012711 is designed for drilling alloy steel, carbon steel, and general alloy materials where a heavy-duty, high-performance drill bit is required. The straight-cylindrical shank fits standard three-jaw drill chucks on benchtop drill presses, magnetic drills, and handheld power drills. The split-point tip is self-centering, which eliminates the need for a center punch on most flat surfaces. The gold oxide coating provides mild lubricity and corrosion resistance during storage and use. With a flute length of 2-15\/16 inches and an overall length of 4-1\/4 inches, this bit handles typical through-hole and blind-hole jobber-length applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter K size  -  0.2810 inches decimal equivalent, heavy-duty grade for demanding applications\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning for self-centering entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eM7 high speed steel construction for toughness and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating provides lubricity and surface protection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute with tapered web for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber-length drill bit for use in standard three-jaw drill chucks accepting a 0.2810-inch straight-cylindrical shank; suitable for drilling alloy steel, alloy, and carbon steel workpieces in industrial and maintenance applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a properly sized drill chuck and tighten securely before operation. Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Apply cutting fluid or coolant when drilling harder alloy steels to extend bit life and maintain dimensional accuracy. Inspect the cutting edges and split point for wear or chipping before each use and replace the bit if edge integrity is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2810 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 Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/4 inches\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: 0.2810 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M7 High Speed Steel\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, Carbon Steel, Alloy\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: T3HD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.63 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: 012711\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRIUMPH TWIST DRILL","offers":[{"title":"Default Title","offer_id":67910408274226,"sku":"012711","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/993397bfbc18e87a2e39c2d83928897a.jpg?v=1791197807","url":"https:\/\/voomisupply.com\/products\/triumph-twist-drill-012711-drill-bit-letter-k-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
