The lead screw is the pointed, threaded tip that pulls the bit through wood and guides the cutting head into the material. When the lead screw on a self-feed bit becomes worn, damaged, or stripped, replacing it restores full cutting performance without requiring a completely new bit. This part is sold in a pack of 5, making it a practical stock item for electricians, plumbers, and other trades that rely on self-feed bits for boring through framing and joists.\u003c\/p\u003e\n\u003cp\u003eSelf-feed bits are standard tools in rough-in work across residential and light commercial construction. They are used to drill large-diameter holes through wood studs, plates, and joists for routing pipe, conduit, and cable. The LENOX 3390012LS lead screw is compatible with LENOX self-feed bit models in the LL100 through LL256 range. Keeping replacement lead screws on hand reduces downtime when a bit tip fails mid-job, particularly on high-volume installations where bits see heavy daily use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbon steel construction for durability in wood-boring applications\u003c\/li\u003e\n  \u003cli\u003eThreaded lead screw design pulls the bit through material and centers the cut\u003c\/li\u003e\n  \u003cli\u003eReplaces worn or damaged tips on self-feed bits without replacing the full bit\u003c\/li\u003e\n  \u003cli\u003eCompatible with LENOX self-feed bit models LL100 through LL256\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 5 for job-site convenience and parts inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with LENOX self-feed drill bits in the LL100 through LL256 range as stated by the manufacturer.

Before replacing the lead screw, ensure the drill is unplugged or the battery pack is removed. Use the appropriate wrench or bit tool to remove the worn screw and thread in the replacement, securing it firmly before returning the bit to service. Do not overtighten in a way that damages the bit body threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Type\u003c\/strong\u003e: Lead Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Type Compatibility\u003c\/strong\u003e: Self-Feed Bits\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Models\u003c\/strong\u003e: LL100 through LL256\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: LENOX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3390012LS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LENOX","offers":[{"title":"Default Title","offer_id":51544404361522,"sku":"3390012LS","price":18.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b6ba65912790152d3287dc8c45494b2.jpg?v=1785926275","url":"https:\/\/voomisupply.com\/products\/lenox-3390012ls-lead-screw-self-feed-drill-bit-replacement-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
