All bits are machined from high-speed steel with an oxide finish and feature a 118-degree split-point geometry for fast, accurate starts on metal surfaces. The 1\/2-inch round shank diameter allows these oversized bits to chuck into standard 1\/2-inch capacity drill presses and hand drills without requiring a large-capacity chuck. Overall length is 7.75 inches. The set is packaged in a plastic storage case. It is designed for general-purpose metalworking and multipurpose drilling applications and is installed or operated by machinists, maintenance technicians, fabricators, and experienced tradespeople.\u003c\/p\u003e\n\u003cp\u003eThis set is suited for residential and commercial metalworking tasks where drilling holes from 0.56 inch up to 1 inch is required. The reduced shank design makes it practical for use on standard drill presses, magnetic drills, and hand-held drills equipped with a 1\/2-inch chuck. Typical applications include through-hole drilling in mild steel plate, structural angle iron, pipe flanges, and general fabrication work. The oxide coating provides mild corrosion resistance and reduces chip welding during cutting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8-piece set covers 9\/16 inch to 1 inch in 1\/16-inch increments\u003c\/li\u003e\n  \u003cli\u003e118-degree split-point tip for accurate, self-starting entry with reduced walking\u003c\/li\u003e\n  \u003cli\u003eReduced shank diameter of 1\/2 inch fits standard 1\/2-inch drill chucks\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for general-purpose metalworking durability\u003c\/li\u003e\n  \u003cli\u003eOxide finish provides mild corrosion resistance and lubricity\u003c\/li\u003e\n  \u003cli\u003eIncludes plastic storage case for organized transport and protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/2-inch capacity drill chucks on drill presses, magnetic base drills, and corded hand drills used in general metalworking and multipurpose drilling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDrill bit installation and use should be performed by a qualified machinist or tradesperson familiar with proper speeds and feeds for high-speed steel tooling in metal. Secure the workpiece firmly before drilling and verify the chuck is tightened fully around the 1\/2-inch reduced shank before operation. Always wear appropriate eye protection and ensure the drill press table or workpiece fixture is locked down. Do not exceed the rated capacity of the drill or chuck.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T180D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Bit Size\u003c\/strong\u003e: 9\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Bit Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStep Increments\u003c\/strong\u003e: 1\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Reduced Shank Length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Metalworking, Multipurpose Drill Bits\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStorage Unit Type\u003c\/strong\u003e: Case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStorage Unit Material\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 090598\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRIUMPH TWIST DRILL","offers":[{"title":"Default Title","offer_id":67906078900530,"sku":"090598","price":418.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/332f457bbe3b3c6b1319d1a05d04d24f.jpg?v=1791164481","url":"https:\/\/voomisupply.com\/products\/triumph-twist-drill-090598-reduced-shank-drill-bit-set","provider":"Voomi Supply","version":"1.0","type":"link"}
