Built from M7 high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced heat buildup compared to uncoated HSS bits. The 135-degree split point self-centers on contact, eliminating the need for a center punch on most surfaces. With a 5-5\/8 inch overall length and a right-hand spiral flute, this bit is a standard workhorse for machinists, fabricators, maintenance techs, and trade professionals who drill frequently in varied materials.\u003c\/p\u003e\u003cp\u003eThis bit fits typical jobber-length drill applications across residential, commercial, and light industrial settings. It is sized at 29\/64 inch (0.4531 inch decimal equivalent) with a matching straight-cylindrical shank of the same diameter, making it compatible with standard drill chucks and drill presses. Primary workpiece materials include aluminum, aluminum alloy, bronze, superalloy, and wood. The web-thinned, tapered web configuration reduces thrust requirements and improves chip evacuation, which is especially useful when drilling deeper holes in softer metals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction rated for heavy-duty, high-performance drilling\u003c\/li\u003e\n\u003cli\u003eTitanium nitride (TiN) coating extends cutting life and resists wear\u003c\/li\u003e\n\u003cli\u003e135-degree split point self-centers on entry, reducing or eliminating center-punch prep\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces drilling thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank seats securely in standard 3-jaw drill chucks and drill press spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length replacement or stock bit for use in hand drills, drill presses, and CNC drilling operations where a 29\/64 inch straight-shank bit is specified.

Secure the shank fully into the chuck jaws and tighten evenly to prevent slippage under load. Use appropriate cutting fluid or coolant when drilling metals to manage heat, even though this bit does not support through-coolant delivery. Follow applicable OSHA and shop safety standards for rotating tool operation, including proper eye protection and secure workpiece fixturing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 29\/64 inches (0.4531 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4-3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 29\/64 inches\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: M7 High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003ePoint Type\u003c\/strong\u003e: Split Point, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Aluminum, Aluminum Alloy, Bronze, Superalloy, Wood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T1HDG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.01 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: 012829\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRIUMPH TWIST DRILL","offers":[{"title":"Default Title","offer_id":67911504888114,"sku":"012829","price":36.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/187bcd00d381a26acf12051c8bb6e877.jpg?v=1791211229","url":"https:\/\/voomisupply.com\/products\/triumph-twist-drill-012829-jobber-drill-bit-29-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
