The bit features a 135-degree split point that self-centers on contact, reducing walking and the need for a center punch. A black oxide coating provides mild corrosion resistance and reduces friction during cutting. The hex shank measures 1\/4 inch across flats and locks securely into quick-change chuck systems, impact drivers, and standard three-jaw chucks. Overall length is 4.25 inches with a flute length of 2.375 inches, and the maximum drilling depth is 2.375 inches.\u003c\/p\u003e\u003cp\u003eThis jobber drill bit is suited for light-gauge metal fabrication, electrical rough-in work, HVAC sheet metal drilling, plumbing bracket installation, and general trade use on job sites. The right-hand spiral flute design clears chips efficiently during through-hole drilling. The hex shank makes it compatible with quick-change driver systems commonly used in the field, reducing tool swap time. It is sold individually with a minimum order quantity of 5 units per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point self-centers on contact, minimizing bit walking on smooth surfaces\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction handles general-purpose drilling across multiple materials\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating reduces friction and provides mild corrosion resistance\u003c\/li\u003e\n\u003cli\u003e1\/4 inch hex shank fits quick-change chucks and standard three-jaw chucks\u003c\/li\u003e\n\u003cli\u003eRight-hand regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eJobber length with 4.25 inch overall length suits most standard drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill bit compatible with any 1\/4 inch hex-drive quick-change chuck, standard keyless or keyed drill chuck, or hex-accepting impact driver rated for drilling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed electrician, HVAC technician, or plumber installing this bit should ensure the drill is powered off and the chuck is fully secured before beginning work. Use appropriate cutting fluid or lubricant when drilling hardened metals to extend bit life. Follow applicable worksite safety codes and wear eye protection at all times. Inspect the cutting edges before each use and replace the bit if chipping or dullness is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint 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\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral, Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inch (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 49356\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Specification\u003c\/strong\u003e: Yes\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: 4935639\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51541833056562,"sku":"4935639","price":34.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b07c9f8d85281a85a7c42eefb5e757f8.jpg?v=1785886251","url":"https:\/\/voomisupply.com\/products\/irwin-4935639-3-16-inch-jobber-drill-bit-hss-hex-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
