The 135-degree split-point tip features four cutting edges that prevent walking on contact and allow fast penetration without a center punch. Black oxide tempering reduces frictional heat and improves chip evacuation during drilling. The extended 12-inch length reaches into deep cavities, wall assemblies, and structural members that standard-length bits cannot access. Licensed tradespeople and experienced DIYers working on rough-in and retrofit applications will find the extra reach especially useful when drilling through framing, conduit runs, and layered materials.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling wood, plastic, wallboard, plywood, soft metals, aluminum, brass, and bronze. It handles occasional use in stainless steel and other hard metals. Typical applications include electrical and plumbing rough-in through deep framing members, HVAC ductwork penetrations, and general construction tasks where a standard-length bit falls short. The carded single-bit packaging makes it convenient for job-site procurement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split-point tip with four cutting edges prevents walking and eliminates the need for a center punch\u003c\/li\u003e\n\u003cli\u003eExtra length at 12 inches reaches deep framing, wall cavities, and stacked material assemblies\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides durability across wood, plastic, and metal substrates\u003c\/li\u003e\n\u003cli\u003eBlack oxide tempering treatment reduces frictional resistance and improves chip flow during drilling\u003c\/li\u003e\n\u003cli\u003eRecommended for wood, plastic, wallboard, plywood, soft metals, aluminum, brass, and bronze\u003c\/li\u003e\n\u003cli\u003eSuitable for occasional use in stainless steel and other hard metals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use extra-length drill bit compatible with standard 3\/8-inch and 1\/2-inch keyed or keyless drill chucks accepting 3\/16-inch round shanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and used by electricians, plumbers, HVAC technicians, and general contractors. Always disconnect power at the panel or de-energize the work area before drilling near electrical components. Secure the workpiece before drilling, use appropriate eye protection, and reduce feed pressure when transitioning between material layers to prevent bit deflection. Consult NEC or IFGC clearance requirements when drilling through structural or fire-rated assemblies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.52 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 14.96 inches x 1.89 inches x 0.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: 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: DISSTON COMPANY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 504662\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DISSTON CO","offers":[{"title":"Default Title","offer_id":51723695456562,"sku":"504662","price":23.58,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29c893bff65191c77b8a3736d0b480fa.jpg?v=1788607465","url":"https:\/\/voomisupply.com\/products\/disston-company-504662-extra-length-hss-drill-bit-3-16x12in","provider":"Voomi Supply","version":"1.0","type":"link"}
