Each bit features a 135-degree split point for fast, accurate starts without center-punching, and a bronze oxide finish that reduces friction and extends tool life. The straight shank design fits standard three-jaw chucks without adapters. Bit sizes step from 1\/16 inch to 1\/2 inch in 1\/32-inch increments, giving technicians a complete fractional range for drilling steel, stainless, cast iron, and other hard materials. The set ships in a metal storage case and is sold as a single unit.\u003c\/p\u003e\u003cp\u003eThis set is suited for commercial and industrial metalworking environments where hard-metal drilling is routine. It is also appropriate for multipurpose trade use on job sites requiring a broad range of fractional hole sizes in ferrous and non-ferrous metals. HVAC, plumbing, and electrical contractors working with structural steel, sheet metal framing, or enclosures will find the 1\/16-inch to 1\/2-inch size range covers the majority of common fastener clearance and conduit knockout applications. The Series SAD21HD designation identifies this as a heavy-duty production-grade set.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction for superior hardness and heat resistance when drilling hardened steels and stainless\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces walking and eliminates the need for center-punching on most surfaces\u003c\/li\u003e\n\u003cli\u003eBronze oxide finish lowers friction and dissipates heat during high-speed drilling\u003c\/li\u003e\n\u003cli\u003e15-piece fractional set covers 1\/16 inch through 1\/2 inch in 1\/32-inch step increments\u003c\/li\u003e\n\u003cli\u003eStraight shank fits standard drill chucks without collets or adapters\u003c\/li\u003e\n\u003cli\u003eMetal storage case keeps bits organized and protects cutting edges between uses\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard three-jaw drill chucks accepting straight-shank bits up to 1\/2 inch, compatible with benchtop drill presses, hand drills, and right-angle drills used in metalworking and general trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this set is performed by licensed or qualified tradespeople working with drill presses or portable drills in metalworking contexts. Always secure the workpiece with a vise or clamp before drilling to prevent rotation. Use appropriate cutting fluid or coolant when drilling hardened or stainless steel to extend bit life, even though coolant-through capability is not built into these bits. Inspect each bit for wear or chipping before use and replace any bit that shows damage to the cutting edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bronze Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Drill Bit Size\u003c\/strong\u003e: 1\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Bit Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStep Increments\u003c\/strong\u003e: 1\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Jobber Length\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Metalworking, Multipurpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStorage Unit Material\u003c\/strong\u003e: Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStorage Unit Type\u003c\/strong\u003e: Case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SAD21HD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.1 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: 099826\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRIUMPH TWIST DRILL","offers":[{"title":"Default Title","offer_id":67911762280754,"sku":"099826","price":198.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13811d39981716377f2e4f6c408f388c.jpg?v=1791218994","url":"https:\/\/voomisupply.com\/products\/triumph-twist-drill-099826-cobalt-drill-bit-set-15-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
