Built from M7 high-speed steel with a gold oxide coating, this bit delivers extended wear resistance in high-volume drilling applications. The 135-degree split point provides self-centering entry without the need for a center punch, reducing walkout on hard or smooth surfaces. A right-hand spiral flute with web-thinned, tapered web construction improves chip evacuation and reduces cutting torque. Licensed HVAC, mechanical, and general trade professionals rely on this series for repetitive small-hole work in metal and non-metal substrates.\u003c\/p\u003e\n\u003cp\u003eThe 012643 is engineered for drilling into alloy steel, carbon steel, and wood, making it a practical choice across metal fabrication, HVAC sheet-metal work, mechanical assembly, and general maintenance applications. With a 1.25-inch flute length and 2.25-inch overall length, it fits standard keyless and keyed drill chucks used in bench drills and handheld power tools. The straight-cylindrical shank seats securely in 3-jaw chucks without slippage. The T2HD series is rated as heavy-duty, high-performance tooling appropriate for production or repetitive drilling environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge 43 size at 0.0890 inches diameter for precise small-hole work\u003c\/li\u003e\n  \u003cli\u003eM7 high-speed steel construction rated for heavy-duty, high-performance use\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with self-centering geometry eliminates center-punch step\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating reduces friction and extends cutting edge life\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web improves chip flow and reduces thrust force\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix for reliable chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-cylindrical chuck systems; compatible with drilling alloy steel, carbon steel, and wood workpieces as specified in the T2HD series application data.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by a machinist, fabricator, or trade professional using a keyed or keyless 3-jaw drill chuck. Secure the straight-cylindrical shank fully into the chuck before operation to prevent runout. Match spindle speed to workpiece material and bit diameter per standard machining reference charts. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling steel to extend tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 43\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0890 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\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\u003eFlute Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0890 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eTool Application\u003c\/strong\u003e: Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Wood\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T2HD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: TRIUMPH TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 012643\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRIUMPH TWIST DRILL","offers":[{"title":"Default Title","offer_id":67905970110770,"sku":"012643","price":35.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4052658e95cb8c21f54b816eed97171b.jpg?v=1791161436","url":"https:\/\/voomisupply.com\/products\/triumph-twist-drill-012643-wire-size-43-hss-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
