Built from cobalt steel with a bright finish, this bit features a 135-degree split-point tip that reduces walking at startup and allows for faster penetration with less feed pressure. The straight shank is compatible with standard drill chucks. At 2.75 inches overall length, this is a compact, true jobber-length format suited to benchtop drill presses, hand drills, and CNC setups where consistent hole quality is required.\u003c\/p\u003e\u003cp\u003eThis bit is intended for industrial and commercial end users including machinists, fabricators, plumbers, electricians, and HVAC technicians who need reliable small-diameter drilling in ferrous and non-ferrous metals. The cobalt steel construction provides elevated heat resistance compared to standard high-speed steel bits, making it appropriate for drilling harder materials such as stainless steel and cast iron. Packaged individually, it is a direct replacement or add-to-kit option for 1\/8-inch diameter work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt steel construction for improved heat resistance and hardness\u003c\/li\u003e\n\u003cli\u003e135-degree point angle reduces bit walking and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eStraight shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eBright finish for easy visual inspection of bit wear\u003c\/li\u003e\n\u003cli\u003eJobber-length format balances reach and rigidity for general drilling tasks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or stock bit for standard 3-jaw drill chucks accepting straight-shank bits in 1\/8-inch diameter across benchtop drill presses, hand drills, and light CNC equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and changed by machinists, fabricators, and trade technicians using a standard chuck key or keyless chuck. Always power down and de-energize the drill or drill press before changing bits. Secure the shank fully in the chuck jaws and confirm the bit is centered before operation. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Diameter\u003c\/strong\u003e: 1\/8 inches (0.125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Configuration\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IRWIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3016008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51524586242354,"sku":"3016008","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19353a125f8d34c49536ec82661e2812.jpg?v=1785452480","url":"https:\/\/voomisupply.com\/products\/irwin-3016008-jobber-drill-bit-1-8-in-cobalt-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
