Each bit features a 135-degree split point that reduces walking and allows drilling to begin without a center punch. The bronze oxide finish helps resist heat and corrosion during high-speed operation. Bit sizes step in 1\/64-inch increments from 1\/16 inch up to 1\/2 inch, covering the most common hole sizes in metal fabrication, maintenance, and mechanical service work. The set is stored in a metal case for organized jobsite access.\u003c\/p\u003e\n\u003cp\u003eThis set is suited for drilling into steel, stainless steel, cast iron, and other hard metals encountered in HVAC, plumbing, electrical, and general mechanical trades. The cobalt construction handles the heat generated when cutting through harder alloys where standard high-speed steel bits would dull prematurely. Straight shanks are compatible with standard 3-jaw drill chucks on corded drills, cordless drills, and drill presses. The jobber length geometry balances reach and rigidity for most through-hole and shallow-depth drilling tasks on structural members, enclosures, and equipment housings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material provides superior heat resistance for drilling hard metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces bit walking and eliminates the need for center punching in most situations\u003c\/li\u003e\n  \u003cli\u003eBronze oxide coating helps extend bit life by reducing friction and heat buildup\u003c\/li\u003e\n  \u003cli\u003e29-piece set steps from 1\/16 inch to 1\/2 inch in 1\/64-inch increments\u003c\/li\u003e\n  \u003cli\u003eStraight shank fits standard 3-jaw drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMetal storage case keeps bits indexed and protected between uses\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3-jaw drill chucks accepting straight-shank bits up to 1\/2 inch.

Ensure the drill is powered off and the chuck is fully tightened around the shank before operating. Use appropriate cutting fluid or lubricant when drilling hard alloys to extend bit life and maintain hole quality. Wear ANSI-rated eye protection when drilling metal, and secure workpieces firmly to prevent rotation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 29\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\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\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bronze Oxide\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\/64 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\u003eStorage Unit Type\u003c\/strong\u003e: Metal Case\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\u003eWeight\u003c\/strong\u003e: 4 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: 099822\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRIUMPH TWIST DRILL","offers":[{"title":"Default Title","offer_id":67913212395826,"sku":"099822","price":388.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c27f3f4660a65c8e0a015c13f2e0844.jpg?v=1791243579","url":"https:\/\/voomisupply.com\/products\/triumph-twist-drill-099822-cobalt-drill-bit-set-29-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
