The bit measures 3\/8 inch in diameter and 5 inches in overall length, with a 135-degree split-point tip that reduces walking on contact and starts cutting immediately without a center punch on most surfaces. Construction uses cobalt alloy steel throughout the body, providing heat resistance during high-friction drilling operations. The web is built thick for rigidity, reducing flex and breakage risk under load. This bit is sized for jobber-length applications and fits standard 3\/8-inch or larger drill chucks. Electricians, pipefitters, HVAC techs, and general tradespeople reach for cobalt bits when working with conduit bodies, structural steel, and equipment enclosures.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling into ferrous and non-ferrous metals in both residential and commercial trade applications. Typical use cases include drilling through steel junction boxes, HVAC equipment panels, stainless fastener clearance holes, structural steel members, and metal framing. The 3\/8-inch diameter is a common size for conduit knockouts, lag bolt clearance, and anchor bolt pass-throughs. The cobalt alloy composition makes it a practical choice wherever heat buildup from friction would degrade a standard twist bit prematurely.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt alloy steel construction for high heat resistance during metal drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split-point tip reduces bit walking and improves bite on hard surfaces\u003c\/li\u003e\n  \u003cli\u003eThick web design increases rigidity and resists breakage under lateral load\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch diameter x 5 inch length suits jobber-length drilling tasks\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard 3\/8-inch and larger keyed or keyless drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber-length cobalt drill bit for use in any standard drill or drill press accepting a 3\/8-inch shank.

Secure the workpiece firmly before drilling to prevent rotation and bit damage. Start at a lower RPM for larger diameter bits in hard materials, increasing feed pressure gradually. Always wear appropriate eye protection when operating drill bits on metal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBit Type\u003c\/strong\u003e: Cobalt Jobber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Material\u003c\/strong\u003e: Cobalt Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 8.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: China\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: IRWIN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 26135434\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51138421227826,"sku":"26135434","price":32.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305533730.png?v=1778255947","url":"https:\/\/voomisupply.com\/products\/irwin-26135434-cobalt-alloy-drill-bit-3-8-x-5-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
