The bit measures 3\/8 inches in diameter with a 5 inches overall length and a 3.625 inches flute length. The 135-degree split point geometry reduces walking on entry and requires less feed pressure compared to standard 118-degree points. At 80 HRC hardness, the HSS blank provides toughness and heat resistance for drilling through steel, cast iron, aluminum, and similar materials.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for electricians, plumbers, HVAC technicians, and general contractors who need a reliable jobber-length bit for drilling through metal framing, pipe hangers, brackets, and structural steel in residential and commercial applications. The jobber-length format makes it compatible with standard 3\/8-inch and 1\/2-inch keyed or keyless chucks on corded and cordless drills. It is sold individually, making it practical as a single replacement or supplemental bit for an existing set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating increases surface hardness and reduces friction for longer service life\u003c\/li\u003e\n  \u003cli\u003e135-degree split point starts on contact and reduces bit walking without center punching\u003c\/li\u003e\n  \u003cli\u003e80 HRC hardness rating provides durability in demanding drilling applications\u003c\/li\u003e\n  \u003cli\u003eJobber-length format fits standard drill chucks and is compatible with common drill press setups\u003c\/li\u003e\n  \u003cli\u003e3.625 inches flute length provides adequate chip clearance for through-hole drilling in typical material thicknesses\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber-length replacement drill bit suitable for use with standard 3\/8-inch and 1\/2-inch drill chucks in handheld drills and bench-mounted drill presses.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall this bit into a properly rated chuck and tighten securely before operation. Ensure workpieces are clamped or secured before drilling to prevent rotation. Use appropriate cutting fluid or lubricant when drilling ferrous metals to reduce heat buildup and prolong bit life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.625 inches\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: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 80 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBit Series\u003c\/strong\u003e: Jobber Length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\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: IR63924\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51346999509298,"sku":"IR63924","price":15.44,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310499696.jpg?v=1782096088","url":"https:\/\/voomisupply.com\/products\/irwin-ir63924-hss-jobber-drill-bit-3-8-in-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
