Self-feed bits use a center screw tip to pull the bit through material without requiring heavy axial pressure, making them a standard tool for electricians and plumbers drilling through joists, studs, and plates during rough-in work. The SDF138 is sold as a single bit and is sized at 1-3\/8 inches, a diameter commonly required for conduit, pipe, and cable rough-in applications.\u003c\/p\u003e\n\u003cp\u003eThis bit is well suited for residential and light commercial rough-in installations where trade professionals need to bore through dimensional lumber, engineered lumber, or wood plate stock. Electricians use this diameter for running conduit or cable bundles through framing. Plumbers use it for drain, waste, and vent pipe rough-in through floor and wall framing. The 1-3\/8 inch diameter accommodates a range of common pipe and conduit sizes in typical trade applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-3\/8 inch cutting diameter sized for common conduit and pipe rough-in work\u003c\/li\u003e\n  \u003cli\u003eSpeed-D-Feed self-feed design pulls bit through material with minimal axial pressure\u003c\/li\u003e\n  \u003cli\u003eCenter screw tip provides positive feed and accurate hole placement\u003c\/li\u003e\n  \u003cli\u003eSingle-bit unit quantity for targeted replacement or kit supplementing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard self-feed bit compatible with 1\/2 inch chuck corded drills and right-angle drills commonly used in electrical and plumbing rough-in applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSelf-feed bits are installed and operated by licensed electricians, plumbers, and general trade contractors during rough-in framing stages. Always confirm that the drill chuck is fully tightened and rated for the bit shank diameter before operation. Inspect framing members for embedded nails, screws, or metal plates before drilling to avoid bit damage or kickback. Follow applicable NEC or IPC hole-spacing and edge-distance requirements when boring through structural framing members.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBit Type\u003c\/strong\u003e: Speed-D-Feed Self-Feed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Unit\u003c\/strong\u003e: 1\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: L H Dottie Co\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SDF138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DOTTIE","offers":[{"title":"Default Title","offer_id":51560528937266,"sku":"SDF138","price":174.33,"currency_code":"USD","in_stock":false}],"url":"https:\/\/voomisupply.com\/products\/l-h-dottie-co-sdf138-speed-d-feed-drill-bit-1-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
